Full Text Available This article examines the interconnections between environmental issues and the protection of human rights, in a process that began in the United Nations Conference on the Human Environment (Stockholm, 1972 and has been developed by the greening of the regional human rights systems. In the Inter-American system the article 11 of the Additional Protocol to the American Convention on Economic, Social and Cultural Rights of 1988 — the Protocol of San Salvador — guarantees the right to a healthy environment. However the American Convention (on its arts. 3-25, 44-51 and 61-69 and its Additional Protocol (on its arts. 8, 13 and 19.6 only allow the submission of individual petitions to the Inter-American Commission and the possible acting of the Inter-American Court, in complaints containing alleged violations of civil and political rights, trade union rights and the right to education. Despite the lack of devices that are capable to ensure an effective protection to the right to a healthy environment, by itself, the Inter-American Court has demonstrated the greening of the human rights, which means, in other words, that it is quite possible to protect environmental issues by the demonstration of its interconnections with civil and political rights that are directly protected by the inter-American system. Therefore, it is necessary to understand the contributions of the jurisprudence of the Inter-American Court in the strengthening of the civil and political rights in cases related to environmental issues.

Recently the potential environmental hazard of photovoltaic modules together with their management as waste has attracted the attention of scientists. Particular concern is aroused by the several metals contained in photovoltaic panels whose potential release in the environment were scarcely investigated. Here, for the first time, the potential environmental hazard of panels produced in the last 30 years was investigated through the assessment of up to 18 releasable metals. Besides, the corresponding ecotoxicological effects were also evaluated. Experimental data were compared with the current European and Italian law limits for drinking water, discharge on soil and landfill inert disposal in order to understand the actual pollution load. Results showed that less than 3% of the samples respected all law limits and around 21% was not ecotoxic. By considering the technological evolutions in manufacturing, we have shown that during the years crystalline silicon panels have lower tendency to release hazardous metals with respect to thin film panels. In addition, a prediction of the amounts of lead, chromium, cadmium and nickel releasable from next photovoltaic waste was performed. The prevision up to 2050 showed high amounts of lead (30t) and cadmium (2.9t) releasable from crystalline and thin film panels respectively. Copyright © 2015 Elsevier B.V. All rights reserved.

Potential and limitations of environmental design with LCA tools

Directory of Open Access Journals (Sweden)

Alexander Hollberg

2017-10-01

Full Text Available The built environment has a very high impact on the environment. Architects can largely define the environmental impact a building will cause throughout its lifetime through its design. Especially the choice of material and the type of construction can be influenced in early design stages. To quantify the environmental impact, tools for Life Cycle Assessment (LCA are used. This paper discusses the results of four case studies of applying four different novel LCA tools in four different academic courses at different universities. The results show that the success of applying LCA tools highly depends on the point of time during the design process and the design strategy the student pursues. If the right tool is used at the right moment and matches the design strategy, it can help to improve the architectural quality and reduce environmental impacts. In most cases however, the time of application did not fit, resulting in additional effort for applying the LCA tool. In consequence, the architectural elaboration of the design and the improvement of environmental performance compete against each other. Either the architectural quality suffers or the tool is employed late and the environmental performance cannot be improved. Even if the point in time of the tool application is right, the success depends highly on the design strategy. The number of tools is growing and there is an adequate tool available for each design stage. The design strategy has to match the tool and this requires a willingness to adapt the design approach. The issue of environmental design shifted from a lack of adequate tools to the lack of adequate design approaches. Tools can be easily taught in seminars. Environmental design strategies, however, have to be included in design studios and developed throughout the entire design phase to become part of architectural education.

International environmental governance: Lessons learned from Human Rights Institutional Reform

Energy Technology Data Exchange (ETDEWEB)

Fauchald, Ole Kristian

2011-07-01

This report focuses on the possibility of establishing a High Commissioner for the Environment and transforming the UNEP Governing Council into a Council for the Environment. For this purpose, it considers the parallels between human rights regimes and environmental regimes. It provides a short-list of functions to be covered by a reformed environmental governance regime, and discusses how the reform can be coordinated with UNEP, as well as with the current and future institutional framework for sustainable development. The report also discusses how the reform can be related to fifteen core multilateral environmental agreements. Finally, the report considers how the reform can be carried out through a discussion of five separate options: a decision by the UN General Assembly, by the ECOSOC, or by the UNEP Governing Council, as well as through agreements between conferences of parties of environmental agreements, or directly between states. A main purpose of the report, which has been commissioned by the Norwegian Ministry for the Environment, is to provide input to the preparations for the Rio+20 Conference in 2012.(auth)

2016-07-01

Full Text Available In the current period, followed by the industrial revolution, the damaging effects of the one-dimensional attitude towards the environment caused by human have had countless hazards. To cope with these risks, the respect and protection of environmental values has attracted today's urban human attention once again and the issues about the human right to a decent, safe and healthy environment which is called briefly" environmental rights ", have widely been discussed. In fact, this research is formed on the basis of the principle that the right to a healthy environment, must be respected in the design of public spaces and the legal aspects of this principle must be considered in dealing with these spaces, so one of the necessary contexts to the conversion of today’s public spaces to valuable urban places would be provided. Therefore, in this study the human right to a healthy, safe and decent environment and the related concepts has been reviewed and the role of the environment in the process of transforming urban spaces to urban places has been discussed. This study also emphasizes on the role of the noise pollution of the urban public spaces as one of the threatening factors of the right to the environment, in the inefficiency and disorder in the process of the conversion of these spaces to public places and while reviewing the laws to reduce such pollution in urban public spaces, it stresses the necessity of considering these rules in designing the urban public spaces. This study uses descriptive and analytic research methodology and investigation techniques of literature review by using library studies.

Environmental potentials of policy instruments to mitigate nutrient emissions in Chinese livestock production.

Science.gov (United States)

Zheng, Chaohui; Liu, Yi; Bluemling, Bettina; Mol, Arthur P J; Chen, Jining

2015-01-01

To minimize negative environmental impact of livestock production, policy-makers face a challenge to design and implement more effective policy instruments for livestock farmers at different scales. This research builds an assessment framework on the basis of an agent-based model, named ANEM, to explore nutrient mitigation potentials of five policy instruments, using pig production in Zhongjiang county, southwest China, as the empirical filling. The effects of different policy scenarios are simulated and compared using four indicators and differentiating between small, medium and large scale pig farms. Technology standards, biogas subsidies and information provisioning prove to be the most effective policies, while pollution fees and manure markets fail to environmentally improve manure management in pig livestock farming. Medium-scale farms are the more relevant scale category for a more environmentally sound development of Chinese livestock production. A number of policy recommendations are formulated as conclusion, as well as some limitations and prospects of the simulations are discussed. Copyright © 2014 Elsevier B.V. All rights reserved.

Beyond Litigation: The Need for Creativity in Working to Realise Environmental Rights

Directory of Open Access Journals (Sweden)

Lisa Chamberlain

2017-06-01

Full Text Available Environmental harm is one of the biggest challenges facing communities living in poverty across the world. Unfortunately, in developing strategies to combat environmental harm, the lawyers that support such communities often tend to focus purely on litigation. Yet there are many reasons why litigation is not ideally suited to the environmental context. These reasons include the need for speed in order to avert irreversible harm quickly, the difficulty in quantifying and proving environmental harm using conventional legal tests, the very technical subject matter with which judges are often unfamiliar and the challenge of securing scientific experts. Fortunately litigation is not the only option, and a wealth of alternative strategies to realise environmental rights exist. Using the campaign to protect the Mapungubwe World Heritage Site in South Africa as a case study, this article will examine three such alternatives: namely the linkages between advocacy campaigns and company share price, community learning exchanges and an interesting model for collaboratively monitoring compliance by mining companies.

Potential of mediation for resolving environmental disputes related to energy facilities

Energy Technology Data Exchange (ETDEWEB)

None

1979-12-01

This study assesses the potential of mediation as a tool for resolving disputes related to the environmental regulation of new energy facilities and identifies possible roles the Federal government might play in promoting the use of mediation. These disputes result when parties challenge an energy project on the basis of its potential environmental impacts. The paper reviews the basic theory of mediation, evaluates specific applications of mediation to recent environmental disputes, discusses the views of environmental public-interest groups towards mediation, and identifies types of energy facility-related disputes where mediation could have a significant impact. Finally, potential avenues for the Federal government to encourage use of this tool are identified.

Potential environmental effects of energy conservation measures in northwest industries

Energy Technology Data Exchange (ETDEWEB)

Baechler, M C; Gygi, K F; Hendrickson, P L

1992-01-01

The Bonneville Power Administration (Bonneville) has identified 101 plants in the Pacific Northwest that account for 80% of the region's industrial electricity consumption. These plants offer a precise target for a conservation program. PNL determined that most of these 101 plants were represented by 11 major industries. We then reviewed 36 major conservation technologies used in these 11 industrial settings to determine their potential environmental impacts. Energy efficiency technologies designed for industrial use may result in direct or indirect environmental impacts. Effects may result from the production of the conservation measure technology, changes in the working environment due to different energy and material requirements, or changes to waste streams. Industry type, work-place conditions, worker training, and environmental conditions inside and outside the plant are all key variables that may affect environmental outcomes. To address these issues this report has three objectives: Describe potential conservation measures that Bonneville may employ in industrial programs and discuss potential primary impacts. Characterize industrial systems and processes where the measure may be employed and describe general environmental issues associated with each industry type. Review environmental permitting, licensing, and other regulatory actions required for industries and summarize the type of information available from these sources for further analysis.

A potential Human Rights Act in Queensland and inclusion of the right to health.

Brolan, Claire E; Herron, Lisa; Carney, Anna; Fritz, Eva M; James, Judy; Margetts, Miranda

2018-04-01

To identify the level of public support for a Human Rights Act for Queensland (HRAQ) and for inclusion of the right to health by participants in a public inquiry process. We reviewed the 492 written submissions to the Legal Affairs and Community Safety Committee's Inquiry into a potential HRAQ and the transcripts documenting the public hearings held by the Committee in 2016. A total of 465 written submissions were analysed; 419 (90%) were for a HRAQ. More than 80% of the 'for' submissions advocated the right to health's inclusion. At the seven public hearings, 72 persons made verbal submissions and most supported a HRAQ. Five major themes were identified in our synthesis of the public hearing transcripts. Three related specifically to health and human rights: 1) the need to consider the holistic health and human rights of Indigenous Queenslanders and Indigenous Queensland communities; 2) instilling a human rights culture in Queensland; and 3) access to health care and the underlying determinants of health. The other two themes related to the conduct of the Inquiry: 4) the importance of community participation in developing a HRAQ; and 5) concerns about the public consultation processes. This study found strong support in the majority of submissions for the Queensland Parliament to draft and enact a HRAQ, and for the inclusion of the right to health in such legislation. Implications for public health: The Queensland Parliament's enactment of a HRAQ that expressly included the right to health would increase the accountability and transparency of government health (and related) decision making and resource allocation, and would better identify and address health inequities across the state. This Act is imperative for improving the health and wellbeing of all Queenslanders, particularly rural and remote and Aboriginal and Torres Strait Islander Queenslanders. © 2017 The Authors.

PUBLIC PARTICIPATION AND WATER USE RIGHTS

Directory of Open Access Journals (Sweden)

Phillipa King

2015-11-01

Full Text Available The conservation and protection of water resources is paramount in the safeguarding of environmental rights and the attainment of sustainable development in South Africa. Although the National Water Act 36 of 1998 (the NWA seeks to provide a framework for ensuring the sustainable use of water resources, its application has been hindered by capacity and enforcement constraints, a legacy of water pollution (primarily as a result of mining and industrial activities, and poor resource management. To aggravate this situation, the difficulties in effectively implementing the NWA are exacerbated by inadequate public participation in water use licensing processes. Public participation in environmental decision-making has increasingly received recognition for its role in ensuring administrative justice and the protection of environmental rights. While environmental legislation (in many cases sets out procedures for ensuring that public views are taken into account in environmental decision-making processes, the judiciary has also recognised the pivotal role of public engagement in ensuring administrative justice where environmental rights are at stake. Sound public participation practices play an important role in identifying issues requiring consideration in the context of environmental assessment processes, as well as in ensuring that communities are empowered to monitor, identify and report on potential contraventions of environmental legislation. Water is a vital natural resource which is under significant pressure in South Africa. In the circumstances, effective public participation is crucial to ensuring the protection and equitable use of water resources. It follows that provision for comprehensive public engagement in water use licensing processes is integral to ensuring the sustainable management of water resources. While provision is made in the NWA for public engagement in the context of water use licensing processes, such participation is

Effective environmental protection by the reform of the administrative procedures and administrative legal rights

1978-01-01

The 52nd German Lawyers Meeting will be concerned in its legal department with the question of whether, from the points of view of the guaranteeing of the necessary environmental protection, additional regulations in the administrative procedures and administrative legal rights should be recommended. Here one is concerned, above all, with the problem of whether an administrative legal associations sueing or associations participation in administrative legal procedures is desirable in the interests of environmental protection. A negative answer must be given to this question. Discussion should concentrate on the problematical administrative legal interests, on the strengthening of administrative participation of popular opinion or interests in legal processes, on other improvements in administrative processes and on the legal control by Parliament of environmental protection.

2000-01-01

This book describes the complex processes that underlie the effects of different types of radiation at the cellular, organ and organismic level. Technical terms central to the subject matter are printed in italicize and explained in a glossary along with all physical quantities and dimensional units referred to. Through a systematic presentation of various aspects of the effects of environmental radiation on humans the author has endeavoured to make it clear that any discussion on potential health hazards must be conducted specific to the type of radiation in question. Furthermore, to study these issues meaningfully one must have a knowledge of the scientific basis of interactions between the various types of radiation and biological systems and be able to assess the relative impact of environmental radiation compared with other environmental health hazards

Weighing environmental externalities: Let's do it right

International Nuclear Information System (INIS)

Joskow, P.L.

1992-01-01

Should we as a society adopt policies to internalize external environmental costs? Of course we should. But we should do it correctly. State public utility commissions (PUCs) that are using numerical 'externality adders' reflecting global and regional environmental impacts in the resource planning and selection process are doing it wrong. The use of these adders is likely to lead to higher electricity prices without a commensurate improvement in environmental impacts in the resource planning and selection process are doing it wrong. The use of these adders is likely to lead to higher electricity prices without a commensurate improvement in environmental quality. Alternative approaches for dealing with environmental damages or externalities exist that can lead utilities to take account of the environmental costs associated with the generation of electricity more effectively and at lower cost. This article discusses what an externality is and why the use of environmental adders by PUCs in the resource selection process, while well intentioned, is a bad idea. The author discusses how the most egregious errors associated with the use of adders can be corrected if PUCs insist on using them. Finally, he outlines an alternative approach that state PUCs can pursue which will better serve the electricity customers they are supposed to protect and promote a cleaner environment at the lowest reasonable cost. The author emphasizes that this is not a debate about whether or not environmental costs should be factored into the investment and operating decisions of firms that produce pollution. Rather, it is about how it should be done and whether state PUCs are in a particularly good position to do it well, given their expertise, legal authorities, other responsibilities and scarce resources

Environmental characteristics and utilization potential of metallurgical slag: Chapter 19

Piatak, Nadine; De Vivo, Benedetto; Belkin, Harvey E.; Lima, Annamaria

2018-01-01

Slag, an abundant byproduct from the pyrometallurgical processing of ores, can be an environmental liability or a valuable resource. The most common environmental impact of slag is from the leaching of potentially toxic elements, acidity, or alkalinity that may impact nearby soils and surface water and groundwater. Factors that influence its environmental behavior include physical characteristics, such as grain size and porosity, chemical composition with some slag being enriched in certain elements, the mineralogy and partitioning of elements in more or less reactive phases, water-slag interactions, and site conditions. Many of these same factors also influence its resource potential. For example, crystalline ferrous slag is most commonly used as construction aggregate, whereas glassy (i.e., granulated) slag is used in cement. Also, the calcium minerals found in ferrous slag result in useful applications in water treatment. In contrast, the high trace-element content of some base-metal slags makes the slags economically attractive for extraction of residual elements. An evaluation tool is used to help categorize a particular slag as an environmental hazard or valuable byproduct. Results for one type of slag, legacy steelmaking slag from the Chicago area in the USA, suggest the material has potential to be used for treating phosphate-rich or acidic waters; however, the pH and trace-element content of resulting solutions may warrant further examination.

This paper sets for the description of the methodology, strategies and activities of Obati environmental and urbanistic upgrade. Obati is a 50 km. pipeline, built in 1974, that runs from Barueri to Sao Caetano do Sul terminals. From 70's decade the metropolitan region of Sao Paulo grew tremendously and thousands of poor people happened to live just at Obati's right of way limits. Being aware of its social and environmental responsibility, PETROBRAS decided to improve the situation and settled a brand new program in which engineering works were added to an environmental education and social communication program. The results were the integrity of pipeline's right of way , a better life quality of the neighborhood and the accomplishment and partnership of citizens, company and local government to keep the area safe and to sustain the whole program.

"Just another hoop to jump through?" using environmental laws and processes to protect indigenous rights.

Science.gov (United States)

Middleton, Beth Rose

2013-11-01

Protection of culturally important indigenous landscapes has become an increasingly important component of environmental management processes, for both companies and individuals striving to comply with environmental regulations, and for indigenous groups seeking stronger laws to support site protection and cultural/human rights. Given that indigenous stewardship of culturally important sites, species, and practices continues to be threatened or prohibited on lands out of indigenous ownership, this paper examines whether or not indigenous people can meaningfully apply mainstream environmental management laws and processes to achieve protection of traditional sites and associated stewardship activities. While environmental laws can provide a "back door" to protect traditional sites and practices, they are not made for this purpose, and, as such, require specific amendments to become more useful for indigenous practitioners. Acknowledging thoughtful critiques of the cultural incommensurability of environmental law with indigenous environmental stewardship of sacred sites, I interrogate the ability of four specific environmental laws and processes-the Uniform Conservation Easement Act; the National Environmental Policy Act and the California Environmental Quality Act; the Pacific Stewardship Council land divestiture process; and Senate Bill 18 (CA-2004)-to protect culturally important landscapes and practices. I offer suggestions for improving these laws and processes to make them more applicable to indigenous stewardship of traditional landscapes.

Guidelines for the Review of Environmental-Related Legislation Regarding the Realisation of the Right to Access to Sufficient Food

Directory of Open Access Journals (Sweden)

Inge Snyman

2015-12-01

Full Text Available The development of legislation for the progressive realisation of the right to access to sufficient food is labelled as an international and national objective. Section 27(2 of the Constitution of the Republic of South Africa, 1996 assigns a compulsory mandate to the South African government to take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of the right to access to sufficient food. The United Nations' Food and Agricultural Organization (FAO proposes a three-level strategy for the implementation of the right to food on a national legislative level, namely through: constitutional recognition, the implementation of a food framework law and the reviewing of relevant sectoral legislation. This contribution focuses on the last level of legislative provisioning, namely the reviewing of relevant sectoral legislation which influences, or possibly can, influence the realisation of the right to access to sufficient food. The right to access to sufficient food has multidimensional, interdisciplinary and cross-sectoral characteristics and consequently various sectors are involved in the realisation of the right to access to sufficient food. The FAO determines that the intended purpose will be to identify and review all sectoral legislation that might influence the availability, stability, access and adequacy of food, by means of a proposed reviewing process. The suggested reviewing process of the FAO is comprehensive and diverse; therefore the focus of this contribution is based on the reviewing of relevant environmental-related legislation only. The FAO does not make recommendations with regard to the specific aspects that need to be incorporated in environmental-related legislation to contribute to the progressive realisation of the right to access to sufficient food (in other words the aspects against which environmental-related legislation can be evaluated. Therefore this

Switchgrass-Based Bioethanol Productivity and Potential Environmental Impact from Marginal Lands in China

Full Text Available Switchgrass displays an excellent potential to serve as a non-food bioenergy feedstock for bioethanol production in China due to its high potential yield on marginal lands. However, few studies have been conducted on the spatial distribution of switchgrass-based bioethanol production potential in China. This study created a land surface process model (Environmental Policy Integrated Climate GIS (Geographic Information System-based (GEPIC model coupled with a life cycle analysis (LCA to explore the spatial distribution of potential bioethanol production and present a comprehensive analysis of energy efficiency and environmental impacts throughout its whole life cycle. It provides a new approach to study the bioethanol productivity and potential environmental impact from marginal lands based on the high spatial resolution GIS data, and this applies not only to China, but also to other regions and to other types of energy plant. The results indicate that approximately 59 million ha of marginal land in China are suitable for planting switchgrass, and 22 million tons of ethanol can be produced from this land. Additionally, a potential net energy gain (NEG of 1.75 x 106 million MJ will be achieved if all of the marginal land can be used in China, and Yunnan Province offers the most significant one that accounts for 35% of the total. Finally, this study obtained that the total environmental effect index of switchgrass-based bioethanol is the equivalent of a population of approximately 20,300, and a reduction in the global warming potential (GWP is the most significant environmental impact.

E-learning in medical education: the potential environmental impact.

2018-03-01

Introduction There is a growing interest in the use of e-learning in medical education. However until recently there has been little interest in the potential environmental benefits of e-learning. This paper models various environmental outcomes that might emerge from the use of an e-learning resource (BMJ Learning) in CPD. Methods We modeled the use of e-learning as a component of CPD and evaluated the potential impact of this use on the learner's carbon footprint. We looked at a number of models - all from the perspective of a General Practitioner (GP). We assumed that all GPs completed 50 h or credits of CPD per year. Results High users of e-learning can reduce their carbon footprint - mainly by reducing their travel to face-to-face events (reducing printing also has a small beneficial effect). A high user of e-learning can reduce the carbon footprint that relates to their CPD by 18.5 kg. Discussion As global warming continues to pose a risk to human and environmental health, we feel that doctors have a duty to consider learning activities (such as e-learning) that are associated with a lower carbon footprint.

Shore Side Electricity in Europe: Potential and environmental benefits

International Nuclear Information System (INIS)

Winkel, R.; Weddige, U.; Johnsen, D.; Hoen, V.; Papaefthimiou, S.

2016-01-01

In the context of reducing emissions from the transport sector, the EU Commission envisions a strong modal shift to energy efficient modes including maritime shipping and inland shipping, as an alternative for road transport. In view of the expected growth of the sector, the emissions from waterborne transport are a key concern. When at berth, ships typically use their auxiliary engines to generate electrical power for communications, lighting, ventilation and other on-board equipment. The extended use of vessels’ auxiliary engines augments greenhouse gas (GHG) emissions and air pollution in the adjacent ports, which are typically located in or near densely populated areas, thus leading to dangerous health and environmental effects. Shore Side Electricity (SSE) is an option for reducing the unwanted environmental impacts of ships at berth, i.e. GHG emissions, other air pollutants (NO_x, SO_x, PM) and noise of ships using their auxiliary engines. This paper quantifies the economic and environmental potential for SSE in Europe, through detailed estimation of in-port ships’ emissions and relevant energy demand, providing an insight of the expected barriers for implementation and formulating recommendations on policy actions that could accelerate the implementation of SSE in European harbors. - Highlights: • We model Shore Side Electricity (SSE) options for ports in the European region. • The economic and environmental potential for SSE in Europe is quantified. • The expected barriers for wide implementation of SSE are depicted. • We recommend policy actions that could accelerate SSE implementation.

Bisphenol A (BPA), identified as an endocrine disruptor, is an industrially important chemical that is used as a raw material in the manufacture of many products such as engineering plastics (e.g., epoxy resins/polycarbonate plastics), food cans (i.e., lacquer coatings), and dental composites/sealants. The demand and production capacity of BPA in China have grown rapidly. This trend will lead to much more BPA contamination in the environmental media and in the general population in China. This paper reviews the current literature concerning the pollution status of BPA in China (the mainland, Hong Kong, and Taiwan) and its potential impact on human health. Due to potential human health risks from long-term exposure to BPA, body burden of the contaminant should be monitored. Copyright © 2011 Elsevier Ltd. All rights reserved.

Cellulolytic potential under environmental changes in microbial communities from grassland litter

Directory of Open Access Journals (Sweden)

Renaud eBerlemont

2014-11-01

Full Text Available In many ecosystems, global changes are likely to profoundly affect microorganisms. In Southern California, changes in precipitation and nitrogen deposition may influence the composition and functional potential of microbial communities and their resulting ability to degrade plant material. To test whether environmental changes impact the distribution of functional groups involved in leaf litter degradation, we determined how the genomic diversity of microbial communities in a semi-arid grassland ecosystem changed under reduced precipitation or increased N deposition. We monitored communities seasonally over a period of two years to place environmental change responses into the context of natural variation. Fungal and bacterial communities displayed strong seasonal patterns, Fungi being mostly detected during the dry season whereas Bacteria were common during wet periods. Most putative cellulose degraders were associated with 33 bacterial genera and constituted ~18.2% of the microbial community. Precipitation reduction reduced bacterial abundance and cellulolytic potential whereas nitrogen addition did not affect the cellulolytic potential of the microbial community. Finally, we detected a strong correlation between the frequencies of genera putative cellulose degraders and cellulase genes. Thus, microbial taxonomic composition was predictive of cellulolytic potential. This work provides a framework for how environmental changes affect microorganisms responsible for plant litter deconstruction.

Bevacqua, Christine E; Rice, Clifford P; Torrents, Alba; Ramirez, Mark

2011-05-01

Steroid hormones can act as potent endocrine disruptors when released into the environment. The main sources of these chemicals are thought to be wastewater treatment plant discharges and waste from animal feeding operations. While these compounds have frequently been found in wastewater effluents, few studies have investigated biosolids or manure, which are routinely land applied, as potential sources. This study assessed the potential environmental contribution of steroid hormones from biosolids and chicken litter. Hormone concentrations in samples of limed biosolids collected at a waste treatment plant over a four year period ranged from farms had averages of 41.4ng/g dry weight E1, 63.4ng/g dry weight progesterone, and 19.2ng/g dry weight E1-sulfate (E1-S). Other analytes studied were 17β-estradiol (E2), estriol (E3), 17α-ethinylestradiol (EE2), testosterone, E2-3-sulfate (E2-3-S), and E2-17-sulfate (E2-17-3). Copyright © 2011 Elsevier B.V.

Brandão, Solange E; Bulbovas, Patricia; Lima, Marcos E L; Domingos, Marisa

The tolerance potential against the oxidative injury in native plants from forest ecosystems affected by environmental stressors depends on how efficiently they keep their pro-oxidant/antioxidant balance. Great variations in plant tolerance are expected, highlighting the higher relevance of measuring biochemical leaf trait indicators of oxidative injury in species with similar functions in the forest than in single species. The use of this functional approach seems very useful in the Brazilian Atlantic Forest because it still holds high plant diversity and was the focus of this study. We aimed at determining the tolerance potential of tree species from the Atlantic Forest remnants in SE Brazil against multiple oxidative environmental stressors. We assumed that pioneer tree species are more tolerant against oxidative stress than non-pioneer tree species and that their tolerance potential vary spatially in response to distinct combined effects of oxidative environmental stressors. The study was carried out in three Atlantic Forest remnants, which differ in physiognomy, species composition, climatic characteristics and air pollution exposure. Leaves of three pioneer and three non-pioneer species were collected from each forest remnant during wet (January 2015) and dry periods (June 2015), for analyses of non-enzymatic and enzymatic antioxidants and oxidative injury indicators. Both hypotheses were confirmed. The pioneer tree species displayed biochemical leaf traits (e.g. high levels of ascorbic acid, glutathione and carotenoids and lower lipid peroxidation) that indicate their higher potential tolerance against oxidative environmental stressors than non-pioneer species. The biochemical leaf traits of both successional groups of species varied between the forest remnants, in response to a linear combination of oxidative environmental stressors, from natural (relative humidity and temperature) and anthropogenic sources (ozone and nitrogen dioxide).

2013-01-01

A simulated oxidation technique was used to examine the impacts of degradation on the surface properties of biochar and the potential implications of the changes in biochar properties were discussed. To simulate the short- and long-term environmental degradation, mild and harsh degradation were employed. Results showed that after mild degradation, the biochar samples showed significant reductions in surface area and pore volumes. After harsh degradation, the biochar samples revealed dramatic variations in their surface chemistry, surface area, pore volumes, morphology and adsorption properties. The results clearly indicate that changes of biochar surface properties were affected by biochar types and oxidative conditions. It is suggested that biochar surface properties are likely to be gradually altered during environmental exposure. This implies that these changes have potential effects for altering the physicochemical properties of biochar amended soils. -- Highlights: •Mild and harsh degradation were employed to simulate natural degradation of biochar. •Mild degradation could reduce the surface area and micropore volumes of biochar. •Harsh degradation caused severe changes of all of the biochar surface properties. •Biochar types and oxidative conditions may dominate the changes of its properties. -- The simulated degradation of biochar in this study could provide a mechanism for forecasting short- or long-term environmental degradation of biochar

Characterizing the Estrogenic Potential of 1060 Environmental ...

Science.gov (United States)

In order to detect environmental chemicals that pose a risk of endocrine disruption, high-throughput screening (HTS) tests capable of testing thousands of environmental chemicals are needed. Alteration of estrogen signaling has been implicated in a variety of adverse health effects including cancer promotion, reproductive deficits, and vascular effects. Here we investigate the estrogenic potential of 1060 chemicals of environmental relevance using a real-time measure of growth kinetics by electrode impedance in the estrogen-responsive human ductal carcinoma, T47D cell line. Cells were treated in concentration response and measurements of cellular impedance were recorded every hour for six days. Progestens, androgens, and mineralocortocoids (progesterone, dihydrotestosterone, aldosterone) invoked a biphasic impedance signature that contrasted with the anticipated exponential impedance observed in response to known estrogen receptor agonists (17β-estradiol, genestein, bisphenol-A, nonylphenol, 4-tert-octylphenol). Several compounds, including bisphenol-A, and genestein caused impedance comparable to that of 17β-estradiol, although at much higher concentrations. Additionally, trenbolone and cyproterone acetate invoked the characteristic biphasic signature observed with other endogenous steroid hormones. The continuous real-time nature of this assay allows for the rapid detection of differential growth characteristics not easily detected by traditional cell prol

Factors in the Development of a Global Substantive Environmental Right

Stephen James Turner

2013-12-01

Full Text Available Owing to the fact that there is currently no international treaty that provides a globally accepted substantive human right for the protection of the environment (Anton and Shelton, 2011; Turner, 2009 there is a case for considering how such a right could or should be developed. This paper considers certain aspects of the potential development of such a right by focussing on key non-state actors that make decisions, which can affect the environment. Consideration is given to three different types of non-state actors: companies (corporations, the World Trade Organisation (WTO and multilateral development banks (MDBs. It specifically examines their ‘constitutional’ purposes and the overall legal constraints that their decision-makers are bound to comply with, and where applicable, the legal obligations that they impose upon their members.Therefore, this approach to the issue focuses on the legal foundations that determine how such actors make decisions and how that can affect the environment. This paper provides a broad perspective to illustrate the commonalities between the actors that are discussed in relation to their decision-making processes. Ultimately it provides an argument in support of the formal development of an international treaty that would create a global substantive environmental right. However it posits that such a treaty should inter alia be designed and framed in a manner, that would develop reformed legal obligations for the types of non-state actors discussed. Debido al hecho de que actualmente no existe ningún tratado internacional que proporcione un derecho humano globalmente aceptado para la protección del medio ambiente (Anton y Shelton 2011, Turner 2009 hay un argumento para considerar cómo podría o debería desarrollarse tal derecho.

Highlights: • We measure the metals released in the leaching solution by samples of PV panels. • We measure the environmental effects by a battery of ecotoxicological tests. • The experimental data are compared with the European and Italian benchmark limits. • We assess the potential emissions of metals from future PV waste. • Experimental results show that the photovoltaic panels present an environmental risk. - Abstract: Recently the potential environmental hazard of photovoltaic modules together with their management as waste has attracted the attention of scientists. Particular concern is aroused by the several metals contained in photovoltaic panels whose potential release in the environment were scarcely investigated. Here, for the first time, the potential environmental hazard of panels produced in the last 30 years was investigated through the assessment of up to 18 releasable metals. Besides, the corresponding ecotoxicological effects were also evaluated. Experimental data were compared with the current European and Italian law limits for drinking water, discharge on soil and landfill inert disposal in order to understand the actual pollution load. Results showed that less than 3% of the samples respected all law limits and around 21% was not ecotoxic. By considering the technological evolutions in manufacturing, we have shown that during the years crystalline silicon panels have lower tendency to release hazardous metals with respect to thin film panels. In addition, a prediction of the amounts of lead, chromium, cadmium and nickel releasable from next photovoltaic waste was performed. The prevision up to 2050 showed high amounts of lead (30 t) and cadmium (2.9 t) releasable from crystalline and thin film panels respectively.

Potential environmental benefits from regulatory consideration of synthetic drilling muds

International Nuclear Information System (INIS)

Burke, C.J.; Veil, J.A.

1995-02-01

When drilling exploration and production wells for oil and gas, drillers use specialized drilling fluids, referred to as muds, to help maintain well control and to remove drill cuttings from the hole. Historically, either water-based muds (WBMs) or oil-based muds (OBMs) have been used for offshore wells. Recently, in response to US Environmental Protection Agency (EPA) regulations and drilling-waste discharge requirements imposed by North Sea nations, the drilling industry has developed several types of synthetic-based muds (SBMs) that combine the desirable operating qualities of OBMs with the lower toxicity and environmental impact qualities of WBMs. This report describes the operational, environmental, and economic features of all three types of muds and discusses potential EPA regulatory barriers to wider use of SBMs

Psychiatry and human rights: a difficult relationship, but with a growing potential.

Science.gov (United States)

Jarab, Jan

2015-01-01

Persons with psychosocial disabilities (mental health problems) are under the protection of the new United Nations Convention on Rights of Persons with Disabilities (CRPD). The CRPD brings a human rights-based approach to disability: it challenges paternalistic views by emphasizing the person as a rights-holder, an active subject, and not just a passive object of care. It also represents a challenge to mainstream human rights movements and mechanisms who have long paid insufficient attention to human rights of persons with (psychosocial) disabilities. It is increasingly understood that human rights of persons with psychosocial disabilities (mental health problems) should not be seen in the narrow perspective, as if the only issue was the most controversial one, that is, deprivation of liberty. In many areas, reform-minded psychiatrists have themselves initiated human rights-friendly reforms. For instance, efforts to implement article 19 of the CRPD—independent living and inclusion in the community—are increasingly becoming part of the mainstream in mental health care. There is potential for further synergy between mental health professionals and human rights activists in looking at the whole range of civil, political, economic, and social rights listed in the Universal Declaration of Human Rights—realizing that all these rights apply also to persons with psychosocial disabilities, and working together towards removing real-life obstacles to their enjoyment.The building of bridges between the two different types of expertise should be encouraged. In this regard, psychiatry would benefit from more cooperation across borders as well as with international human rights bodies, non-governmental organizations and persons with psychosocial disabilities themselves

Environmental assessment of two different crop systems in terms of biomethane potential production

International Nuclear Information System (INIS)

Bacenetti, Jacopo; Fusi, Alessandra; Negri, Marco; Guidetti, Riccardo; Fiala, Marco

2014-01-01

The interest in renewable energy sources has gained great importance in Europe due to the need to reduce fossil energy consumption and greenhouse gas emissions, as required by the Renewable Energy Directive (RED) of the European Parliament. The production of energy from energy crops appears to be consistent with RED. The environmental impact related to this kind of energy primarily originates from crop cultivation. This research aimed to evaluate the environmental impact of different crop systems for biomass production: single and double crop. The environmental performances of maize and maize plus wheat were assessed from a life cycle perspective. Two alternative scenarios considering different yields, crop management, and climatic conditions, were also addressed. One normal cubic metre of potential methane was chosen as a functional unit. Methane potential production data were obtained through lab experimental tests. For both of the crop systems, the factors that have the greatest influence on the overall environmental burden are: fertilizer emissions, diesel fuel emissions, diesel fuel production, and pesticide production. Notwithstanding the greater level of methane potential production, the double crop system appears to have the worse environmental performance with respect to its single crop counterpart. This result is due to the bigger quantity of inputs needed for the double crop system. Therefore, the greater amount of biomass (silage) obtained through the double crop system is less than proportional to the environmental burden that results from the bigger quantity of inputs requested for double crop. - Highlights: • Environmental impact of two crop systems was evaluated • Biomethane specific production tests were carried out • Alternative scenarios (different yields and crop management) were assessed • Maize single crop obtains the better environmental performance • Critical factors are: fertilizer and diesel fuel emissions and diesel fuel

Projections for population growth estimate, on top of the current 7.4 billion world population, an increase of 2 billion people for the next 40 years. It is also projected that 66 per cent of the world population in 2050 will live in urban areas. To accommodate the urban population growth cities are changing continuously land cover to urban areas. Such changes are a threat for natural resources and food production systems stability and capability to provide food and other functions. However, little has been done concerning a rational soil management for food production in urban and peri-urban areas. This study focuses on the assessment of soil lost due to urban expansion and discusses the potential loss regarding the quality of the soil for food production and environmental functions. It is relevant to increase the knowledge on the role of soils in peri-urban areas and in the interaction of physical, environmental and social factors. The methodology consists of assessing the soil quality in and around urban and peri-urban areas. It focuses particularly on the physical properties and the environmental factors, for two periods of time and account the potential losses due to urban expansion. This project is on-going, therefore current advances will be presented and will look for a discussion on the contribution of soil quality for decision-making and land management in urban and peri-urban areas.

Many natural or human-caused disasters release potentially hazardous materials (HM) that may pose threats to the environment and health of exposed humans, wildlife, and livestock. This chapter summarizes the environmentally and toxicologically significant physical, mineralogical, and geochemical characteristics of materials produced by a wide variety of recent disasters, such as volcanic eruptions, hurricanes and extreme storms, spills of mining/mineral-processing wastes or coal extraction by-products, and the 2001 attacks on and collapse of the World Trade Center towers. In describing these characteristics, this chapter also illustrates the important roles that geochemists and other earth scientists can play in environmental disaster response and preparedness. In addition to characterizing in detail the physical, chemical, and microbial makeup of HM generated by the disasters, these roles also include (1) identifying and discriminating potential multiple sources of the materials; (2) monitoring, mapping, and modeling dispersal and evolution of the materials in the environment; (3) understanding how the materials are modified by environmental processes; (4) identifying key characteristics and processes that influence the materials' toxicity to exposed humans and ecosystems; (5) estimating shifts away from predisaster environmental baseline conditions; and (6) using geochemical insights learned from past disasters to help estimate, prepare for, and increase societal resilience to the environmental and related health impacts of future disasters.

Enhancing Environmental Protection and Socio-Economic Development in Africa: A Fresh Look at the Right to a General Satisfactory Environment under the African Charter on Human and Peoples' Rights

Directory of Open Access Journals (Sweden)

Emeka Polycarp Amechi

2009-06-01

Full Text Available The African Charter to Human and Peoples' Rights is an innovative document as it is the first human rights albeit regional instrument to provide for a substantive right to environment. However, the right as provided under the Charter is encumbered as it is linked to the promotion of development. Such linkage has led to the argument that the right can only be invoked where it will not infringe the requirements of socio-economic development. While this issue appears to have engaged the attention of most commentators, there has not been much enquiry into what the right aims to achieve and the implication for the achievement of sustainable development objectives including environmental protection and poverty reduction in Africa. This article therefore seeks to evaluate the utility of the right to the pursuit of sustainable development objectives in Africa.

This paper presents the environmental management experience of TRANSPETRO in the State of Sao Paulo, Brazil, in maintenance services on pipelines and pipeline right-of-way areas, focusing on the requirements of these services in order to ensure the integrity of the system and on the limitations in connection with a great number of authorizations and governmental agencies involved and the use of the environmental management as a solution. These services include, basically, replacement of pipeline sections, geotechnical and upgrading services in right-of-way areas in a pipeline network of about 3700 km, implemented in a wide range of environments, from urban areas to environmentally protected areas. In the first place, consideration is given to the complex legal question related to the various laws and the necessity to obtain approvals such as licenses, authorizations, awards and statements of commitment pertaining to the great number of governmental agencies involved. Subsequently, the main environmental impacts pertaining to said services are approached, with presentation of the tools used in Environmental Management, such as analysis of environmental hazards and aspects, contractual requirements, plans, guideline sheets, procedures, training and monitoring. At the end, a description is presented of the difficulties met, of the solutions adopted and of the new attitudes that are required for a continuous improvement of the process. (author)

New trouble brewing: environmental associations are granted the right to institute group action

Heller, W.

2005-01-01

An important legislative project is the transposition of Directive 2003/35/EC of the European Parliament and the Council about public participation in the development of certain plans and programs related to the environment, and the amendment of Directives 85/337/EEC and 96/61EC of the Council about public participation and access to courts of law. These directives must be transposed into national law and administrative regulations by June 25, 2005. The Directive on Public Participation introduced the right to institute group action. If these provisions were adopted as planned, environmental associations henceforth would be in a position, among other things, to bring action against plant permits, permits under water management and atomic energy laws, allocations of certificates under the new emissions trading system, etc. On February 21, 2005, the German Federal Ministry for the Environment (BMU) presented a first draft bill about supplementary provisions on legal remedies in environmental cases under the EU Directive (Environmental Legal Remedies Act), which is to be discussed with the Associations in the near future. The preface to the ministerial draft bill does not preclude the possibility of the introduction of group action giving rise to procedural delays in specific cases and, as a consequence, to additional expenses in investment projects. Legislation has ways and means to minimize negative consequences. (orig.)

A clarification of the ranking of environmentally related claims in bankruptcy and receivership proceedings, was presented. Also, the liability that a creditor assumes when taking control of a debtor's business or assets, particularly where environmental contaminants are concerned, was explained. The way that environmental law operates and the sorts of liability it imposes and upon whom, was also explained. Generally, environmental legislation imposes liability upon the owner of a contaminated property, whether or not the owner caused or created the problem. However, legislation also exists which imposes liability on the party in control and on the party which caused the contamination. A review of cases which deal with environmental legislation and their impact upon receivers in Saskatchewan and Alberta, was presented. Ways in which secured creditors can assess liability and minimize risks, were also described. The proposed amendments to the Bankruptcy and Insolvency Act (BIA) expand the current limited protection from personal liability for trustees in bankruptcy and extend it to receivers, trustees, monitors and agents

Does every child have a fundamental right to receive a high-quality education? We propose that people's beliefs about whether "nearly everyone" or "only some people" have high intellectual potential drive their positions on education. Three studies found that the more people believed that nearly everyone has high potential, the more they viewed education as a fundamental human right. Furthermore, people who viewed education as a fundamental right, in turn (a) were more likely to support the institution of free public education, (b) were more concerned upon learning that students in the country were not performing well academically compared with students in peer nations, and (c) were more likely to support redistributing educational funds more equitably across wealthier and poorer school districts. The studies show that people's beliefs about intellectual potential can influence their positions on education, which can affect the future quality of life for countless students.

Advertising energy saving programs: The potential environmental cost of emphasizing monetary savings.

Schwartz, Daniel; Bruine de Bruin, Wändi; Fischhoff, Baruch; Lave, Lester

Many consumers have monetary or environmental motivations for saving energy. Indeed, saving energy produces both monetary benefits, by reducing energy bills, and environmental benefits, by reducing carbon footprints. We examined how consumers' willingness and reasons to enroll in energy-savings programs are affected by whether advertisements emphasize monetary benefits, environmental benefits, or both. From a normative perspective, having 2 noteworthy kinds of benefit should not decrease a program's attractiveness. In contrast, psychological research suggests that adding external incentives to an intrinsically motivating task may backfire. To date, however, it remains unclear whether this is the case when both extrinsic and intrinsic motivations are inherent to the task, as with energy savings, and whether removing explicit mention of extrinsic motivation will reduce its importance. We found that emphasizing a program's monetary benefits reduced participants' willingness to enroll. In addition, participants' explanations about enrollment revealed less attention to environmental concerns when programs emphasized monetary savings, even when environmental savings were also emphasized. We found equal attention to monetary motivations in all conditions, revealing an asymmetric attention to monetary and environmental motives. These results also provide practical guidance regarding the positioning of energy-saving programs: emphasize intrinsic benefits; the extrinsic ones may speak for themselves.

With the increasing attention on developing a low-carbon economy, it is necessary to seek appropriate ways on reducing greenhouse gas (GHG) emissions through innovative municipal solid waste management (MSWM), such as urban symbiosis. However, quantitative assessments on the environmental benefits of urban symbiosis, especially in developing countries, are limited because only a limited number of planned synergistic activities have been successful and it is difficult to acquire detailed inventory data from private companies. This paper modifies and applies a two-step simulation system and used it to assess the potential environmental benefits, including the reduction of GHG emissions and saving of fossil fuels, by employing various Japanese plastics recycling/energy-recovery technologies in Shenyang, China. The results showed that among various recycling/energy-recovery technologies, the mechanical waste plastics recycling technology, which produces concrete formwork boards (NF boards), has the greatest potential in terms of reducing GHG emissions (1.66 kg CO(2)e/kg plastics), whereas the technology for the production of refuse plastic fuel (RPF) has the greatest potential on saving fossil fuel consumption (0.77 kg ce/kg-plastics). Additional benefits can be gained by applying combined technologies that cascade the utilization of waste plastics. Moreover, the development of clean energy in conjunction with the promotion of new waste plastics recycling programs could contribute to additional reductions in GHG emissions and fossil fuel consumption.

Hydraulic fracturing technologies, developed over the last 65 years, have only recently been combined with horizontal drilling to unlock oil and gas reserves previously deemed inaccessible. Although these technologies have dramatically increased domestic oil and natural gas production, they have also raised concerns for the potential contamination of local water supplies with the approximately 1,000 chemicals that are used throughout the process, including many known or suspected endocrine-disrupting chemicals. We discuss the need for an endocrine component to health assessments for drilling-dense regions in the context of hormonal and antihormonal activities for chemicals used. We discuss the literature on a) surface and groundwater contamination by oil and gas extraction operations, and b) potential human exposure, particularly in the context of the total hormonal and antihormonal activities present in surface and groundwater from natural and anthropogenic sources; we also discuss initial analytical results and critical knowledge gaps. In light of the potential for environmental release of oil and gas chemicals that can disrupt hormone receptor systems, we recommend methods for assessing complex hormonally active environmental mixtures. We describe a need for an endocrine-centric component for overall health assessments and provide information supporting the idea that using such a component will help explain reported adverse health trends as well as help develop recommendations for environmental impact assessments and monitoring programs.

Adam, David P.; Mahood, Albert D.

1981-01-01

Many Chrysophyte algae produce morphologically distinctive, siliceous, microscopic cysts during a resting stage of their life cycles; these cysts are often preserved in sediments. Scanning electron microscopy and Nomarski optics permit much more detailed observation of these cysts than was heretofore possible. We have used an ecologic and biogeographic approach to study the distribution of cyst forms in sediments and have established that many cyst types are found only in specific habitats, such as montane lakes, wet meadows, ephemeral ponds, and Sphagnum bogs. In the samples we have studied, cysts seem to be most common in fluctuating fresh-water habitats of low to moderate pH and some winter freezing. Numerous taxonomic problems have yet to be resolved. We believe that chrysophyte cysts have the potential to become a useful tool for both modern environmental assessments and paleoecological studies of Cenozoic fresh-water lacustrine deposits.

This report addresses the topic of environmental citizenship in the United States. The term refers to responsibilities each of us have with respect to helping our communities and nation make sound environmental decisions. This research centers on the citizens and what we ought to be doing, as opposed to what the government ought to be doing for us, to improve environmental citizenship. This report examines four central questions: What are the requirements (i.e., responsibilities) of citizenship vis-a-vis environmental decision- making processes; what constraints limit people`s ability to meet these requirements; what does our form of governance do to help or hinder in meeting these requirements; and what recommendations can be put forth to improve public participation in environmental decision making?

Animal rights and environmemntal rights in Brazilian Supreme Court

Full Text Available The subject. The article analyzes the arguments of the Federal Supreme Court of Brazil, used in the consideration of disputes concerning animal rights, in comparison with the developments of theorists in this field.The purpose of the article is to justify the necessity of respect for the rights of animals and the “animal dignity” by the courts.The methodology includes formal-legal analysis of courts’ decisions, comparative-legal analysis and synthesis as well as formal-logical analysis of scientific researches in the field of animal rights.The main results and scope of application. It is wrong to claim that the Brazilian Supreme Court decision in “Vaquejada” case (or even in “Farra do Boi” or cockfights cases would be an increase in the process of a supposed recognition of animal rights in the Brazilian constitutional jurisdiction. In such cases, most of the Judges who participated in the trial pondered and reinforced the prevalence of environmental law, including it wildlife protection (and non-submission of the animals to cruelty, pursuant to Art. 225, § 1, VII, of the Brazilian Constitution. In this way, it would have been disregarded the categorical difference between environmental law and animal rights. The Constitution itself encourages confusion between those categories when dealing with the prohibition of animal cruelty in a chapter on the environment (chap. VI. This article argues that the focus on the statement of environmental law, the Supreme Court allows them to be strengthened arguments considered as obstacles to the defenders of animal rights, particularly the anthropocentric argument that the balanced environment is important to make possible to human beings more quality of life. Analyzing the decisions, especially in of Vaquejada and Farra do Boi cases, it appears that points many important analyzed in the theoretical debate about animal rights, such as the notions of “animal dignity” and “flourishing life�

Earthquakes can be devastating to built infrastructure and the natural environment, as evidenced by the March 2011, M = 9.0 earthquake, and subsequent tsunami, in Japan. As seen in the Japanese event, environmental damage caused by secondary disasters (tsunami, leakage from a nuclear reactor) can equal or exceed the impacts of the primary event. In order to develop an environmental assessment system to examine secondary disasters, a comprehensive environmental impact evaluation was conducted after the Wenchuan earthquake that occurred on 12 May 2008 in the Sichuan Province, China. This evaluation focused on several key environmental elements such as wastewater, drinking water, soil, solid waste, radiation, and ecosystem-level effects. As part of this assessment, an analysis of root causes and potential solutions was conducted for key issues such as population relocation and resettlement in temporary dwellings, recovery of environmental protection functions, industrial development strategies and production recovery. Methods for post-quake environmental assessment were developed, utilizing GIS-based techniques for spatial evaluation of primary and secondary disaster patterns. The goal of this exercise was the development of effective assessment methods that can be rapidly applied in a post-disaster situation to reduce and mitigate damage caused by secondary disasters, and facilitate the recovery of impaired environmental management structure and function. - Highlights: Black-Right-Pointing-Pointer A comprehensive post-quake environmental risk evaluation system was developed. Black-Right-Pointing-Pointer The research identifies potential long-term environmental risks in many aspects. Black-Right-Pointing-Pointer The research analyzes potential solutions for many typical post-disaster issues. Black-Right-Pointing-Pointer Effective assessment methods can be applied in a post-disaster situation to reduce damage caused by secondary disasters.

Cocaine potentiates ketamine-induced loss of the righting reflex and sleeping time in mice. Role of catecholamines.

Cocaine in graded doses potentiated ketamine-induced loss of the righting reflex and sleeping time. Potentiation of drug-induced sleep with cocaine was not a generalized phenomenon inasmuch as it had no effect on sleep induced by pentobarbital or hexobarbital and decreased sleep induced by phenobarbital. Pentylenetetrazole reduced ketamine sleep but d-amphetamine had a potentiative action. dl-alpha-Methyl-p-tyrosine methyl ester itself increased both the number losing the righting reflex and the sleeping time induced by ketamine. However, the effect cocaine on sleeping time was blocked 3 h after the dl-alpha-methyl-p-tyrosine methyl ester was given. The alpha and beta adrenergic blocking drugs, phenoxybenzamine and propranolol, increased the number of animals losing the righting reflex with ketamine, and phenoxybenzamine lengthened the sleeping time. Alpha and beta adrenergic agonists, l-phenylephrine and isoproterenol, increased the number of animals going to sleep with ketamine but did not significantly alter how long they would sleep. The agonists had no effect on the cocaine interaction with ketamine, whereas the antagonists blocked the effect of cocaine. Both stimulation and blockade of dopamine receptors led to increased loss of the righting reflex and sleeping time with ketamine but only receptor blockade antagonized the effect of cocaine on ketamine-induced sleep. Thus, both the noradrenergic and dopaminergic systems appear to be involved in the ability of cocaine to potentiate ketamine-induced sleep.

Thorough examination of the physicochemical characteristics of a Ti-processing residue was undertaken, including mineralogical, geochemical, and radiochemical characterization, and an investigation of the environmental toxicity of soft-water leachate generated from the residue. Concentrations of most metals measured in the leachate were low; thus, the residue is unlikely to leach high levels of potentially toxic elements on exposure to low-ionic strength natural waters. Relative to stringent ecosystem health-based guidelines, only chromium concentrations in the leachate exceeded guideline concentrations for 95% species protection; however, sulfate was present at concentrations known to cause toxicity. It is likely that the high concentration of calcium and extreme water hardness of the leachate reduced the bioavailability of some elements. Geochemical modeling of the leachate indicated that calcium and sulfate concentrations were largely controlled by gypsum mineral dissolution. The leachate was not toxic to the microalga Chlorella sp., the cladoceran Ceriodaphnia dubia, or the estuarine bacterium Vibrio fischeri. The Ti-processing residue exhibited an absorbed dose rate of 186 nGy/h, equivalent to an annual dose of 1.63 mGy and an annual effective dose of 0.326 mGy. In summary, the results indicate that the Ti-processing residue examined is suitable for productive use as an environmental amendment following 10 to 100 times dilution to ameliorate potential toxic effects due to chromium or sulfate.

2013-01-01

Process energy integration and continuous improvement of process technology are increasing issues to ensure profitability of chemical productions. These objectives are increasingly important due to long-term environmental impact of energy degradation, such as resource depletion, emissions and the release of waste heat. The earlier energy conservation, process economics and environmental aspects are integrated into the process development, the easier and less expensive it is to improve the process design. In this work different distillation process design alternatives have been considered with respect to evaluations of process economics and potential environmental impacts. Optimum design alternatives are analyzed related to these objectives. A multi-criteria decision making technique such as (Analytic Hierarchy Process) AHP is applied for ranking the alternatives. This method reveals that the heat pump distillation unit which has the highest score of 52 % is the best alternative when compare with base case. In terms of the effluent streams the base case has a less potential environmental impact (PEI) compared with heat pump. The lower total PEI/ kg (7.45E-01) of the base case illustrates that the material utilization efficiency of the base case is better than the heat pump whose PEI/ kg is 8.14E-01. (author)

Monetary or environmental appeals for saving electricity? –Potentials for spillover on low carbon policy acceptability

Steinhorst, Julia; Matthies, Ellen

2016-01-01

The acceptability of low carbon policies is an important precondition for energy system transitions, such as the German Energiewende. This long-term experimental study examines the potential for behavioural spillover on the acceptability of low carbon policies, caused by a framed intervention to promote electricity saving behaviour. Clients of a German energy provider were randomly assigned to continuously receive electricity saving tips with either monetary framing (saving potential in €) or environmental framing (saving potential in CO_2). The control group did not receive any information. In two follow-up surveys, four (N=333) and nine months (N=258) later, participants rated the acceptability of several low carbon policies. A pre-survey assessed the personal ecological norm for saving electricity. Participants with strong personal ecological norms reported generally higher policy acceptability. After environmental framing they also indicated higher acceptability compared to the monetary framing or control group. These results indicate that information campaigns should be designed carefully in order to promote positive spillover effects. Environmental framing of private-sphere behaviour can increase the disposition for further pro-environmental behaviour in the public sphere, e.g. policy acceptability. When appealing to monetary benefits in pro-environmental behaviour, there is a risk of inhibiting positive spillover effects. - Highlights: •Policy acceptability may be influenced by type of framing and individual factors. •We examined long-term spillover effects in association with type of framing. •Framing (environmental vs. monetary) interacts with personal ecological norms. •For strong personal ecological norms, environmental framing increases acceptability. •Also, strong personal ecological norms increase low carbon policy acceptability.

Waste management is a successful instrument to minimize generated waste and improve environmental conditions. In spite of the large share of developing countries in the textile industry, limited information is available concerning the waste management strategies implemented for textiles on those countries and their environmental impacts. In the current study, two waste management approaches for hazardous solid waste treatment of acrylic fibers (landfill and incineration) were investigated. The main research questions were: What are the different impacts of each waste management strategy? Which waste management strategy is more ecofriendly? Life cycle assessment was employed in order to model the environmental impacts of each waste streaming approach separately then compare them together. Results revealed that incineration was the more ecofriendly approach. Highest impacts of both approaches were on ecotoxicity and carcinogenic potentials due to release of metals from pigment wastes. Landfill had an impact of 46.8 % on human health as compared to 28 % by incineration. Incineration impact on ecosystem quality was higher than landfill impact (68.4 and 51.3 %, respectively). As for resources category, incineration had a higher impact than landfill (3.5 and 2.0 %, respectively). Those impacts could be mitigated if state-of-the-art landfill or incinerator were used and could be reduced by applying waste to energy approaches for both management systems In conclusion, shifting waste treatment from landfill to incineration would decrease the overall environmental impacts and allow energy recovery. The potential of waste to energy approach by incineration with heat recovery could be considered in further studies. Future research is needed in order to assess the implementation of waste management systems and the preferable waste management strategies in the textile industry on developing countries.

Full Text Available In recent years, great interest in metallic nanoparticles has been observed, both because of their unlimited application possibilities, and also because of the unusual biological, chemical and physical features. It is expected that developments in nanotechnology will become the main promoter of scientific and technological innovations in the coming decades. Searching for a new and safe alternative to chemical pesticides, high hopes are associated with nanotechnology development. Particularly useful may be preparations containing nanoscale metal particles with strong antimicrobial properties. Importantly, safe and non-toxic for the plant components of biological origin may be used in nanoparticles synthesis. This article is a description of the potential applications of nanomaterials in environmental protection, which may become the basis for developing of new protection plant products with antimicrobial properties relative to plant pathogens and non-toxic to higher organisms.

Citizen Participation, Access to Environmental Information and Education in Uruguayan Environmental Law

Full Text Available Our country has followed a clear trend towards the recognition of various mechanisms of citizen participation and access to public information regarding environmental issues A few years ago, if, for instance, a person or group of people, concerned about the potential environmental impact caused by the establishment of a factory in their neighborhood, requested information from the Authorities, such request would have most likely been rejected. At present, there is a clear law-making policy towards acknowledging the possibility for a diversity of social players to be involved at different levels. In a State structured under a social rule of law, both community participation and civil society access to information in possession of the State, regarding issues that may affect the environment, are fundamental rights. Both concepts, information and participation, must go hand in hand, as the first operates as a condition to exercise the second. Civil society involvement in an environmental issue could never occur if, for instance, information held by the Government is not made available. In addition to protecting fundamental human rights, these concepts are enshrined in participatory democracy. They also enable civil society to be involved in environmental pollution issues. This paper is intended to provide a detailed research on the different instruments enshrining citizen participation and access to public information about environmental issues.

The Savannah River Site (SRS) is a 310-square-mile United States Department of Energy nuclear facility located along the Savannah River near Aiken, South Carolina. During operations, which started in 1951, hazardous substances (chemicals and radionuclides) were released to the environment. The releases occurred as a result of inadvertent spills and waste disposal in unlined pits and basins which was common practice before environmental regulations existed. The hazardous substances have migrated to the vadose zone and groundwater in many areas of the SRS, resulting in 515 waste units that are required by environmental regulations, to undergo characterization and, if needed, remediation. In the initial years of the SRS environmental cleanup program (early 1990's), the focus was to use common technologies (such as pump and treat, air stripping, excavation and removal) that actively and tangibly removed contamination. Exclusive use of these technologies required continued and significant funding while often failing to meet acceptable clean-up goals and objectives. Recognizing that a more cost-effective approach was needed, SRS implemented new and complementary remediation methods focused on active and passive technologies targeted to solve specific remediation problems. Today, SRS uses technologies such as chemical / pH-adjusting injection, phyto-remediation, underground cutoff walls, dynamic underground stripping, soil fracturing, microbial degradation, baro-balls, electrical resistance heating, soil vapor extraction, and micro-blowers to more effectively treat contamination at lower costs. Additionally, SRS's remediation approach cost effectively maximizes cleanup as SRS works pro-actively with multiple regulatory agencies. Using GIS, video, animation, and graphics, SRS is able to provide an accurate depiction of the evolution of SRS groundwater and vadose zone cleanup activities to convince stakeholders and regulators of the effectiveness of various cleanup

Environmental assessments estimate, evaluate and predict the consequences of natural processes and human activities on the environment. Long-term ecosystem observation and research networks (LTERs) are potentially valuable infrastructure to support environmental assessments. However, very few environmental assessments have successfully incorporated them. In this study, we try to reveal the current status of coupling LTERs with environmental assessments and look at the challenges involved in improving this coupling through exploring the role that Chinese Ecological Research Network (CERN), the LTER of China, currently plays in regional environment assessments. A review of official protocols and standards, regional assessments and CERN researches related to ecosystems and environment shows that there is great potential for coupling CERN with environment assessments. However in practice, CERN does not currently play the expected role. Remote sensing and irregular inventory data are still the main data sources currently used in regional assessments. Several causes led to the present situation: (1) insufficient cross-site research and failure to scale up site-level variables to the regional scale; (2) data barriers resulting from incompatible protocols and low data usability due to lack of data assimilation and scaling; and (3) absence of indicators relevant to human activities in existing monitoring protocols. For these reasons, enhancing cross-site monitoring and research, data assimilation and scaling up are critical steps required to improve coupling of LTER with environmental assessments. Site-focused long-term monitoring should be combined with wide-scale ground surveys and remote sensing to establish an effective connection between different environmental monitoring platforms for regional assessments. It is also necessary to revise the current monitoring protocols to include human activities and their impacts on the ecosystem, or change the LTERs into Long

Influence of Environmental Parameters on Trichoderma Strains with Biocontrol Potential

2003-01-01

Full Text Available Several mycoparasitic strains belonging to the filamentous fungal genus Trichoderma are promising candidates for the biological control of plant pathogenic fungi. When planning the application of antagonistic Trichoderma strains for the purposes of biological control, it is very important to consider the environmental parameters affecting the biocontrol agents in the soil. A series of abiotic and biotic environmental parameters has an influence on the biocontrol efficacy of Trichoderma. Some important parameters to be considered are the effects of temperature, water potential and pH, and the presence of pesticides, metal ions and antagonistic bacteria in the soil. Most of the Trichoderma strains are mesophilic. Low temperatures in winter may cause a problem during biological control by influencing the activity of the biocontrol agents. Another problem emerging during the application of Trichoderma strains as biocontrol agents is that they cannot tolerate dry conditions, however, we may need biocontrol agents against plant pathogenic fungi which are able to grow and cause disease even in dry soils. The pH characteristics of the soil also belong to the most important environmental parameters affecting the activities of mycoparasitic Trichoderma strains. Within the frames of a complex integrated plant protection strategy, we may have to combine Trichoderma strains with chemical pesticides or metal compounds, therefore it is important to collect information about the effects of pesticides and metal ions on the biocontrol strains. Antagonistic soil bacteria may also have negative effects on the biocontrol abilities of Trichoderma strains, therefore it may be advantageous if a biocontrol strain possesses bacterium- degrading abilities as well. This review will discuss the literature about the influence of temperature, water potential, pH, pesticides, metal ions and antagonistic bacteria on mycoparasitic Trichoderma strains including the results of our

The Environmental Mitigation Potential of Photovoltaic-Powered Irrigation in the Production of South African Maize

Directory of Open Access Journals (Sweden)

Sarah Wettstein

2017-09-01

Full Text Available Agriculture is under pressure to reduce its environmental impact. The use of renewable energy sources has potential to decrease these impacts. Maize is one of the most significant crops in South Africa and approximately 241,000 hectares are irrigated. This irrigation is most commonly powered by grid electricity generated using coal. However, South Africa has high solar irradiation, which could be used to generate photovoltaic electricity. The aim of this study was to determine the environmental mitigation potential of replacing grid-powered irrigation in South African maize production with photovoltaic irrigation systems using Life Cycle Assessment. The study included the value chain of maize production from cultivation to storage. Replacing grid electricity with photovoltaic-generated electricity leads to a 34% reduction in the global warming potential of maize produced under irrigation, and—applied at a national level—could potentially reduce South Africa’s greenhouse gas emissions by 536,000 t CO2-eq. per year. Non-renewable energy demand, freshwater eutrophication, acidification, and particulate matter emissions are also significantly lowered. Replacing grid electricity with renewable energy in irrigation has been shown to be an effective means of reducing the environmental impacts associated with South African maize production.

1995-01-01

Treatment chemicals are used in all facets of the natural gas industry (NGI) from well development through transmission and storage of natural gas. The multitude of chemicals used, combined with the dozens of chemical manufacturers and/or suppliers has lead to the availability of hundreds of possible chemical products. Because of the widespread use of chemical products and their numerous sources, the NGI needs access to consistent data regarding their effectiveness and potential environmental impacts. The objective of this work was to evaluate the effectiveness and potential environmental impacts of, chemical products used in the NGI. This assessment was initially focused on biocides and corrosion inhibitors and their use in the gas production, storage and transmission facilities, The overall approach was obtain the necessary data on chemical use and effectiveness directly from the oil and gas industry, supplemented with data/information obtained from the published literature. Five case histories of chemical use were documented and evaluated to assess the effectiveness of these chemicals. Potential environmental impacts were addressed by performing a screening environmental assessment on the use of glutaraldehyde, a widely used biocide. Prototype discharge scenarios were formulated and modeled to evaluate potential impacts to groundwater and surface water. The paper describes the basis for the study, provides an overview of chemical use with a focus on biocides and corrosion inhibitors, describes and assesses the specific uses of chemicals, and presents the results of the environmental assessment. It was found that various chemicals can be effective in treating microbiologically influenced corrosion and souring, but that the effectiveness of specific chemicals is dependent on the operational scenario and the site-specific conditions

Emerging trends in geospatial artificial intelligence (geoAI): potential applications for environmental epidemiology.

2018-04-17

Geospatial artificial intelligence (geoAI) is an emerging scientific discipline that combines innovations in spatial science, artificial intelligence methods in machine learning (e.g., deep learning), data mining, and high-performance computing to extract knowledge from spatial big data. In environmental epidemiology, exposure modeling is a commonly used approach to conduct exposure assessment to determine the distribution of exposures in study populations. geoAI technologies provide important advantages for exposure modeling in environmental epidemiology, including the ability to incorporate large amounts of big spatial and temporal data in a variety of formats; computational efficiency; flexibility in algorithms and workflows to accommodate relevant characteristics of spatial (environmental) processes including spatial nonstationarity; and scalability to model other environmental exposures across different geographic areas. The objectives of this commentary are to provide an overview of key concepts surrounding the evolving and interdisciplinary field of geoAI including spatial data science, machine learning, deep learning, and data mining; recent geoAI applications in research; and potential future directions for geoAI in environmental epidemiology.

This paper investigates the discursive construction of the substantive purposes of environmental assessment (EA). It addresses these purposes by exploring the complex and often multifaceted linkages between political factors and plural views of democracy, public participation, and the role of science that are embedded in environmental and sustainability discourses. The interaction between policy-making and public actors leads to the formulation of divergent and potentially competing rationales for public participation, and for social appraisal more generally. Participatory approaches have also given impetus to the development of several interpretations on the role of science in assessment procedures. Science is important in mediating public participation and the two are therefore reciprocally linked. This leads to discourses that become manifest in the construction of substantive purposes. Discourse analysis in EA is a relevant method for examining trends and patterns in sustainable development. It is argued that public participation is an important, if not decisive, variable in the articulation and civil legitimacy of certain purposes. A general proposition that results from this paper is that EA, although typically presented as an objective scientific tool, is an intrinsically normative process. Enhanced knowledge on the construction, and reconstruction over time, of substantive purposes is required if environmental and sustainability discourses are to be used and understood as meaningful analytical instruments to assess the socio-political implications of EA. - Highlights: Black-Right-Pointing-Pointer Substantive purposes related to environmental assessment may be best analyzed through discourse analysis. Black-Right-Pointing-Pointer Environmental and sustainability discourses are contingent on the level of participatory democracy and civic science.

Portmán Bay is a heavily contaminated area resulting from decades of metal mine tailings disposal, and is considered a suitable shallow-water analogue to investigate the potential ecotoxicological impact of deep-sea mining. Resuspension plumes were artificially created by removing the top layer of the mine tailings deposit by bottom trawling. Mussels were deployed at three sites: i) off the mine tailings deposit area; ii) on the mine tailings deposit beyond the influence from the resuspension plumes; iii) under the influence of the artificially generated resuspension plumes. Surface sediment samples were collected at the same sites for metal analysis and ecotoxicity assessment. Metal concentrations and a battery of biomarkers (oxidative stress, metal exposure, biotransformation and oxidative damage) were measured in different mussel tissues. The environmental hazard posed by the resuspension plumes was investigated by a quantitative weight of evidence (WOE) model that integrated all the data. The resuspension of sediments loaded with metal mine tails demonstrated that chemical contaminants were released by trawling subsequently inducing ecotoxicological impact in mussels' health. Considering as sediment quality guidelines (SQGs) those indicated in Spanish action level B for the disposal of dredged material at sea, the WOE model indicates that the hazard is slight off the mine tailings deposit, moderate on the mine tailings deposit without the influence from the resuspension plumes, and major under the influence of the resuspension plumes. Portmán Bay mine tailings deposit is a by-product of sulphide mining, and despite differences in environmental setting, it can reflect the potential ecotoxic effects to marine fauna from the impact of resuspension of plumes created by deep-sea mining of polymetallic sulphides. A similar approach as in this study could be applied in other areas affected by sediment resuspension and for testing future deep-sea mining sites in

Global energy demand continues to grow and tidal and wave energy generation devices can provide a significant source of renewable energy. Technological developments in offshore engineering and the rising cost of traditional energy means that offshore energy resources will be economic in the next few years. While there is now a growing body of data on the ecological impacts of offshore wind farms, the scientific basis on which to make informed decisions about the environmental effects of other offshore energy developments is lacking. Tidal barrages have the potential to cause significant ecological impacts particularly on bird feeding areas when they are constructed at coastal estuaries or bays. Offshore tidal stream energy and wave energy collectors offer the scope for developments at varying scales. They also have the potential to alter habitats. A diversity of designs exist, including floating, mid-water column and seabed mounted devices, with a variety of moving-part configurations resulting in a unique complex of potential environmental effects for each device type, which are discussed to the extent possible. - Highlights: Black-Right-Pointing-Pointer We review the environmental impacts of tidal barrages and fences, tidal stream farms and wave energy capture devices. Black-Right-Pointing-Pointer Impacts on habitats, species and the water column, and effects of noise and electromagnetic fields are considered. Black-Right-Pointing-Pointer Tidal barrages can cause significant impacts on bird feeding areas when constructed at coastal estuaries or bays. Black-Right-Pointing-Pointer Wave energy collectors can alter water column and sea bed habitats locally and over large distances.

Modeling In-stream Tidal Energy Extraction and Its Potential Environmental Impacts

In recent years, there has been growing interest in harnessing in-stream tidal energy in response to concerns of increasing energy demand and to mitigate climate change impacts. While many studies have been conducted to assess and map tidal energy resources, efforts for quantifying the associated potential environmental impacts have been limited. This paper presents the development of a tidal turbine module within a three-dimensional unstructured-grid coastal ocean model and its application for assessing the potential environmental impacts associated with tidal energy extraction. The model is used to investigate in-stream tidal energy extraction and associated impacts on estuarine hydrodynamic and biological processes in a tidally dominant estuary. A series of numerical experiments with varying numbers and configurations of turbines installed in an idealized estuary were carried out to assess the changes in the hydrodynamics and biological processes due to tidal energy extraction. Model results indicated that a large number of turbines are required to extract the maximum tidal energy and cause significant reduction of the volume flux. Preliminary model results also indicate that extraction of tidal energy increases vertical mixing and decreases flushing rate in a stratified estuary. The tidal turbine model was applied to simulate tidal energy extraction in Puget Sound, a large fjord-like estuary in the Pacific Northwest coast.

Hexabromocyclododecanes (HBCDs) are the subject of recent interest and potential risk assessment particularly in China due to its ubiquitous existence in a variety of environmental media. This paper reviews the recent studies conducted on HBCDs in different environmental media (air, soil, water, river sediment, sewage sludge, biota and daily food) in China. At the same time, human health risks via food and occupational exposure of HBCDs in production plants, expanded polystyrene (EPS) and extruded polystyrene (XPS) plants were assessed. The review reveals that HBCDs levels of air, soil, sediment, sewage sludge, biota and food presented a geographical variation in the eastern coastal regions of China. There were many factors resulting in the variation, such as sampling sites, climate and analytical method. In terms of diastereoisomer, α-HBCD and γ-HBCD were the predominant diastereoisomers in air, soil, sediment, and sewage sludge. In the water, α-HBCD and γ-HBCD shared the major proportion to the total HBCDs. However, only α-HBCD was the predominant diastereoisomer in biota. With regard to human exposure pathway to HBCDs, food was the major route for human exposure to HBCDs, especially meat. In addition, soil and road dust were also important exposure pathways. Furthermore, workers and residents, especially infants in and around waste dumping sites and industrial areas are exposed to the highest HBCDs levels among all the populations studied thus far. HBCDs posed a potential threat to the environment and human health. Therefore, risk assessment and management have an important role to play in preventing and mitigating HBCDs risks.

Highlights: • An advanced method is presented for techno-economic assessment under potential environmental regulatory policy scenarios. • The viability of the contra-rotating open rotor concept is investigated under various environmental policies. • CO_2 taxation is needed to drive the aerospace industry towards greener solutions. - Abstract: Sustainability of the aviation industry, as any other industry, depends on the elasticity of demand for the product and profitability through minimising operating costs. Of paramount importance is assessing and understanding the interdependency and effects of environmentally optimised solutions and emission mitigation policies. This paper describes the development and application of assessment methodologies to better understand the effects of environmental taxation/energy policies aimed at environmental pollution reduction and the future potential economic impact they may have on the adaptation of “greener” novel technologies. These studies are undertaken using a Techno-economic Environmental Risk Assessment approach. The methodology demonstrated allows the assessment of the economic viability of new technologies compared to conventional technologies, for various CO_2 emission taxation and fuel price scenarios. It considers relative increases in acquisition price and maintenance costs. A study undertaken as a ‘proof of concept’ compares a Counter Rotating Open Rotor aircraft with a conventional aircraft for short range operations. It indicates that at current fuel price and with no carbon taxation, a highly fuel efficient technology, such as the one considered, could be rendered economically unviable. The work goes on to demonstrate that in comparison to the conventional aircraft, any economic benefits that may be accrued from improvement in fuel consumption through such a technology, may well be negated through increases in acquisition price and maintenance costs. The work further demonstrates that if policy

2011-01-01

Constitution of the Republic of Indonesia Year 1945 states that the environment is good and healthy life is a human rights and constitutional rights of every citizen of Indonesia. In Indonesia has many industrial and mining activities that produce Norm (Naturally occurring Radioactive Materials) and TENORM (technologically Enhanced Naturally occurring Radioactive Materials). TENORM is a natural radioactive material which due to human activity or process technology increases the potential exposure when compared to the initial state and the potential radiological impact either external or internal radiation exposure. BAPETEN must ensure that the activities undertaken by non-nuclear industry, especially in the handling of radioactive waste at Norm and TENORM which can lead to chronic exposure, carried out securely and safely, both for workers, public and the environment.

Sinha, Parikhit

2017-02-05

In their recent publication in Journal of Hazardous Materials (http://dx.doi.org/10.1016/j.jhazmat.2015.12.018), Tammaro et al. evaluate the potential environmental impacts of an illegal disposal scenario of photovoltaic panels in the European Union. Critical assumptions that underlie the study's conclusions would benefit from clarification. A scenario of photovoltaic panels finely crushed and abandoned in nature is not supported with field breakage data, in which photovoltaic panels remain largely intact with a number of glass fractures or cracks, as opposed to breakage into cm-scale pieces. Fate and transport analysis is necessary to evaluate how leachate transforms and disperses in moving from the point of emissions to the point of exposure, prior to making comparisons with drinking water limits. Some hazardous metal content has declined in both crystalline silicon and thin film panels, including a 50% decline in semiconductor material intensity in CdTe thin film panels (g CdTe/W) from 2009 to 2015. Waste laws, recycling requirements and minimum treatment standards under the EU WEEE Directive, and illegal disposal rates affect the accuracy of forecasts of releasable metal amounts from PV panels in Europe through 2050.

Forte, Annachiara; Zucaro, Amalia; Fagnano, Massimo; Fierro, Angelo

2017-11-15

A life cycle assessment (LCA) was applied to assess the environmental load of a prospective local bioethanol (EtOH) production system in Southern Italy by using lignocellulosic Fiber sorghum (FS) feedstock. A two steps analysis was carried out considering: (i) a "cradle-to-farm gate" LCA to investigate thoroughly the FS cultivation on hilly marginal land and (ii) a "cradle-to-wheels" system boundary encompassing the environmental pressure of the whole EtOH supply-use chain. Primary data related to lignocellulosic biomass production were combined with experimental feedstock conversion processes through advanced second generation technology. The purpose was the evaluation of the environmental performance of different EtOH-gasoline mixtures in midsize passenger cars: E10 (10% of EtOH and 90% of gasoline) and E85 (85% of EtOH and 15% of gasoline). N fertilization appeared as the prevailing contributor of the crop phase. The "cradle-to-wheels" results concerning E10 passenger car disclosed that the main hotspots were represented by the input of low sulphur petrol (66%) and the linked tailpipe emissions (15%), for almost all the impact categories. Otherwise, for E85 flex-fuel vehicle, the major drivers were represented by the feedstock production (46%) and the imported electricity used in the conversion facility (18%). The FS EtOH blends entailed potential environmental benefits compared with the fossil counterpart (gasoline) for climate change, ozone and fossil depletions. Otherwise, they evidenced a worse profile in terms of acidification, eutrophication and particulate matter formation. Within the context of a the prospective territorial bio-refinery network, the comparison of the annual FS bioethanol based systems with similar EtOH scenarios from giant reed perennial crops highlighted: (i) the importance to optimize the N-management for FS feedstock cultivation and (ii) the need to increase the use of the renewable energy carriers along the industrial conversion

Potential for occupational and environmental exposure to ten carcinogens in Toronto

Muller, P. [ToxProbe Inc., Toronto, ON (Canada)

2002-03-01

A study was conducted in which several contaminants were assessed for their toxicological properties, potencies and occupational and environmental exposures in the city of Toronto. The contaminants included 1,3-butadiene, asbestos, benzene, cadmium, chromium, dioxins, formaldehyde, polycyclic aromatic hydrocarbons (PAHs), tetrachloroethylene, and trichloroethylene. The International Agency for Research on Cancer, the United States Environmental Protection Agency, and Health Canada have classified 9 of the 10 substances as human carcinogens. Tetrachloroethylene was classified as a probable human carcinogen. It was noted that there is no level of exposure for these chemicals that is without some risk. The information on the levels of selected contaminants in the workplace were obtained from existing literature. The sectors with the highest number of potentially exposed workers to these contaminants include the textiles industry, footwear manufacturing, wood products manufacturing, rubber products manufacturing, non-metallic mineral products manufacturing, fabricated metal products manufacturing, construction, land transport, and household services. The report discussed sources of emissions, routes and pathways of exposures and environmental levels, including outdoor air levels water concentrations, soil concentrations, and food concentrations. The report does not estimate the actual risk to Toronto residents due to environmental exposure to these carcinogens because data are insufficient to conduct such an assessment. However, some previous studies have indicated that exposure from ambient and indoor air has the greatest impact on human health. It is recommended that the city of Toronto remain up to date on the regulatory status of these chemicals. refs., tabs., figs., appendices.

The environmental and health consequences of climate change, which disproportionately affect low-income countries and poor people in high-income countries, profoundly affect human rights and social justice. Environmental consequences include increased temperature, excess precipitation in some areas and droughts in others, extreme weather events, and increased sea level. These consequences adversely affect agricultural production, access to safe water, and worker productivity, and, by inundating land or making land uninhabitable and uncultivatable, will force many people to become environmental refugees. Adverse health effects caused by climate change include heat-related disorders, vector-borne diseases, foodborne and waterborne diseases, respiratory and allergic disorders, malnutrition, collective violence, and mental health problems. These environmental and health consequences threaten civil and political rights and economic, social, and cultural rights, including rights to life, access to safe food and water, health, security, shelter, and culture. On a national or local level, those people who are most vulnerable to the adverse environmental and health consequences of climate change include poor people, members of minority groups, women, children, older people, people with chronic diseases and disabilities, those residing in areas with a high prevalence of climate-related diseases, and workers exposed to extreme heat or increased weather variability. On a global level, there is much inequity, with low-income countries, which produce the least greenhouse gases (GHGs), being more adversely affected by climate change than high-income countries, which produce substantially higher amounts of GHGs yet are less immediately affected. In addition, low-income countries have far less capability to adapt to climate change than high-income countries. Adaptation and mitigation measures to address climate change needed to protect human society must also be planned to protect

Seasonal characterization of sugarcane vinasse: Assessing environmental impacts from fertirrigation and the bioenergy recovery potential through biodigestion.

Fuess, Lucas Tadeu; Garcia, Marcelo Loureiro; Zaiat, Marcelo

Sugarcane vinasse has been widely used as a soil fertilizer in the Brazilian sucro-alcohol industry for recycling potassium and water. However, the potential negative effects from long-term soil fertirrigation represent a major drawback regarding this practice, whereas the application of biodigestion represents an efficient method for reducing the polluting organic load and recovering bioenergy from vinasse. Regardless of the predicted use for vinasse, an understanding of the potential of each option is imperative, as the seasonal alterations in the inorganic/organic fractions of vinasse directly affect its management. In this context, this study presents a detailed compositional characterization of sugarcane vinasse from a large-scale Brazilian biorefinery throughout the 2014/2015 harvest to assess the environmental effects (due to fertirrigation) and to estimate the biogas energetic potential. Calculated inputs of organic matter into soils due to vinasse land application were equivalent to the polluting load of populations (117-257inhabha -1 ) at least 2-fold greater than the largest Brazilian capital cities (78-70inhabha -1 ). Two-phase biodigestion could efficiently reduce the polluting load of vinasse (23-52inhabha -1 ) and eliminate the negative effects from direct sulfide emissions in the environment. However, a high risk of soil sodification could result from using high doses of Na-based alkalizing compounds in biodigestion plants. Finally, the optimized recovery of bioenergy through biogas (13.3-26.7MW as electricity) could supply populations as large as 305 thousand inhabitants, so that over 30% of the surplus electricity produced by the studied biorefinery could be obtained from biogas. Overall, applying biodigestion in the treatment of vinasse provides important environmental and energetic gains. However, the benefits of reducing the polluting organic load of vinasse through bioenergy recovery may lose their effect depending on the alkalizing strategy

Arsenic and chromium have been identified as soil contaminants from smelting, industrial and mining activities. The potential for human uptake of these elements from soil has been established with highest concentrations found in children, who are particularly susceptible to environmental exposure. This study explores the exposure potential of selected soil trace elements in rural Victoria, Australia, by investigating the relationship between uptake, measured using toenail clippings as the biomarker of exposure, and soil concentrations in two communities: one near current and historic gold mining, the other an agricultural community. We report the preliminary findings of a cross-sectional survey, in which toenail clippings were obtained from 12 children in the former community, and 16 children in the latter.

Aim of this study was to determine by Ion Chromatography ions (Na + , Ca ++ , Mg ++ , NH 4 + , Cl − , Br − , SO 4 2− , NO 3 − , PO 4 3− ) in honeys (honeydew and floral nectar honeys) from different Italian Regions and from countries of the Western Balkan area. The compositional data were processed by multivariate analysis (PCA and HCA). Arboreal honeydew honeys from the Western Balkans had higher concentrations (from two to three times) of some environmental pollutants (Br − , SO 4 2− and PO 4 3− contents), due to industrial and agricultural activities, than those from Italian regions. The cationic profiles were very similar in both groups. Multivariate analysis indicated a clear difference between nectar honeys and arboreal/honeydew honeys (recognition of the botanical origin). These findings point to the potential of ionic constituents of honey as indicators of environmental pollution, botanical origin and authenticity. -- Highlights: •Analysis by IC of honeys from two areas with different environmental pollution (Italy and Balkans). •Chemometric techniques such as PCA and HCA used. •In Balkans area higher Br − , SO 4 2− and PO 4 3− due to industrial and agricultural activities. •Discrimination of honey botanical origin and authenticity on the base of IC data. •Honey ionic profiles as indicators of environmental pollution and botanical origin. -- Capsule: Ionic profiles of honey could be potential indicators of environmental pollution (industrial and agricultural), botanical origin and authenticity

Mapping environmental land use conflict potentials and ecosystem services in agricultural watersheds.

In mountainous watersheds, agricultural land use cause changes in ecosystem services, with trade-offs between crop production and erosion regulation. Management of these watersheds can generate environmental land use conflicts among regional stakeholders with different interests. Although several researches have made a start in mapping land use conflicts between human activities and conservation, spatial assessment of land use conflicts on environmental issues and ecosystem service trade-offs within agricultural areas has not been fully considered. In this study, we went further to map land use conflicts between agricultural preferences for crop production and environmental emphasis on erosion regulation. We applied an agricultural land suitability index, based on multi-criteria analysis, to estimate the spatial preference of agricultural activities, while applying the Revised Universal Soil Loss Equation (RUSLE) to reflect the environmental importance of soil erosion. Then, we classified the agricultural catchment into four levels of land use conflicts (lowest, low, high and highest) according to preference and importance of farmland areas, and we compared the classes by crop type. Soil loss in agricultural areas was estimated as 45.1thayr, and agricultural suitability as 0.873; this indicated that land use conflicts in the catchment could arise between severe soil erosion (environmental importance) and agricultural suitability (land preferences). Dry-field farms are mainly located in areas of low land use conflict level, where land preference outweighs environmental importance. When we applied farmland management scenarios with consideration of services, conversion to highest-conflict areas (Scenario 1) as 7.5% of the total area could reduce soil loss by 24.6%, while fallow land management (Scenario 2) could decrease soil loss 19.4% more than the current scenario (Business as usual). The result could maximize land management plans by extracting issues of spatial

Brazilian waste potential: energy, environmental, social and economic benefits

The potential energy that could be produced from solid wastes in Brazil tops 50 TWh. Equivalent to some 17% of the nation's total power consumption at costs that are competitive with more traditional options, this would also reduce greenhouse gases emissions. Moreover, managing wastes for energy generation purposes could well open up thousands of jobs for unskilled workers. Related to power generation and conservation, energy use requires discussions on the feasibility of each energy supply option, and comparison between alternatives available on the market. Power conservation is compared to projects implemented by the Federal Government, while power generation is rated against thermo-power plants fired by natural gas running on a combined cycle system. Although the operating costs of selective garbage collection for energy generation are higher than current levels, the net operating revenues of this scheme reach some US$ 4 billion/year. This underpins the feasibility of garbage management being underwritten by energy uses and avoided environmental costs. The suggested optimization of the technical, economic, social and environmental sustainability of the expansion of Brazil's power sector consists of compatibilizing the use of fossil and renewable fuels, which is particularly relevant for hybrid thermo-power plants with null account on greenhouse gases emissions

Reclaiming deserted corridors: Rights of way as common property resources

International Nuclear Information System (INIS)

Brown, D.T.

1993-01-01

In Canada, power line transmission corridors are administered and maintained by provincial crown utilities. These corridors have fragmented natural habitats, destroyed biota, and disrupted geological and hydrologic systems. The practices used by utilities to maintain their rights-of-way tend to worsen the environmental and social context of the localities affected by the corridors. If the corridors are considered as common resources, and if co-management of these resources is undertaken involving the utilities and the communities affected by the corridors, public rights-of-way would be created which would have environmental benefits. These corridors would have a recreational potential and could be managed so as to reduce considerably the negative impacts presently generated by current right-of-way management practices. The use of local residents in this management process could ensure that the use of the corridors harmonizes with local needs. Among the obstacles to the co-management of these corridors are the badly defined policies of secondary land use, the restrictions on vegetation maintenance in utility corridors, lengthy approvals processes, and concerns about public liability. To make co-management of these corridors a reality, new policy structures and new procedures have to be developed in cooperation with the utilities and the affected communities. 14 refs., 1 fig

After the development of a working definition of ''environmental refugees'', the study examines existing State obligations in international law (obligations of the State of origin and of third States under human rights law and general public international law), which are relevant for the prevention of ''environmental flight'' as well as for coping with situations of ''environmental flight'' and identifies shortcomings. In a second step and based on this inventory and gap analysis, a catalogue of ''ideal'' State obligations and individual rights aiming at the best possible protection for (potential) ''environmental refugees'' is created. After comparing the advantages and disadvantages of different solution models, a specific, ''ideal'' solution is presented. (orig.)

Intermediate Crops for Energy Supply (ICES) are essential for farming anaerobic digestion development. Catch crops into a three crops over two years sequence decrease environmental risks with a long soil cover. However, their use in anaerobic digestion process is conditioned by their cost and their yield variability. Following the results of 2012 on short growth cycle ICES program conducted by ADEME, Caussade Semences and Methaneva, a new program have been done on summer 2013 to test short growth cycle ICES and winter 2013 - 2014 to test long growth cycle ICES. The aim of this project was to evaluate the agronomic, energetic, economic and environmental characteristics of some plant covers marketed by Caussade Semences. Then field experiments have been conducted on 24 sites all over France. The impact of fertilization was studied too because some trial sites has fertilized the half part of experimental field. 9 short growth cycle ICES and 3 long growth cycle ICES have been tested. The harvesting have been done by geometric weighting between middle of October and beginning of November for the first one and in April for the second. The agronomic yields have been determined for each plant cover and for each trial site. The biochemical methane potentials (BMP) have been evaluated in order to determine the energetic yield of each ICES. The production cost in euro/tDM was calculated for each plant cover and the environmental impact determined by Life Cycle Analysis (LCA). Finally, 3 short growth cycle ICES and 2 long growth cycle ICES could be identified. More generally, no matter what type of ICES, short or long growth cycle, the more important is to plant at the right time and the right place to obtain the higher biomass, that is the more energy for the lowest production cost.

This is an interview with Gary Grant and Naeema Muhammed, leaders of the North Carolina Environmental Justice Network. Each of them talks about where they grew up, their politicization, how their paths crossed, their work together after Hurricane Floyd, and the unique challenges of organizing for social justice for black communities in the South. We learn of their fight against concentrated animal feeding operations (CAFOs), primarily for the hog trade, and they take us up to North Carolina's Moral Monday protests of 2013 against legislation that threatens voting rights, public education, access to medical services, unemployment benefits, workers rights, occupational and environmental health, and women's access to reproductive health care. We are grateful to these two friends of New Solutions for their contribution to the journal, and we hope that their insights regarding struggles for social and environmental justice can serve as guides for us all.

Avoiding or minimizing potential environmental impact is the driving idea behind protecting a population’s health via Environmental Impact Assessments (EIAs) and Strategic Environmental Assessments (SEAs). However, both are often carried out without any systematic approach. This paper describes the findings of a review of HIA, EIA and SEA experiences carried out by the authors, who act as institutional competent subjects at the national and regional levels in Italy. The analysis of how health is tackled in EIA and SEA procedures could support the definition of a protocol for the integration of HIA with EIA and SEA. Although EIA and SEA approaches include the aim of protecting health, significant technical and methodological gaps are present when assessing health systematically, and their basic principles regarding assessment are unsatisfactory for promoting and addressing healthcare concepts stated by the WHO. HIA is still poorly integrated into the decision-making process, screening and monitoring phases are only occasionally implemented, and operational details are not well-defined. The collaborative approach of institutions involved in environment and health is a core element in a systematic advancement toward supporting effective decisions and effective protection of the environment and health. At the Italian national level, the definition of guidelines and tools for HIA, also in relation with EIA and SEA, is of great interest. PMID:25493391

Concept of environment, sustainable development and respect for human rights

Full Text Available The insistence on the definition of environmental protection is an aspiration which has served as prerequisites to the implementation of human rights in a global economic crises. European Regional System has traditionally been focused on the protection of civil and political rights. In the wake of environmental risks that imply the violation of human rights, the emphasis has been placed more on the social, economic and cultural. Collective mechanisms to appeal to the United Nations and the European Court of Human Rights, gave a number of decisions on matters implicating environmental laws and policies. What is to be noted, is the evolution of the guarantees provided under the European Convention on Human Rights, which refers to a substantial understanding of environmental protection, and also including procedural aspects related to the protection of the right to life, privacy, property, information and effective means of appeal. This evolution has been launched by the growing need for states to take preventive measures and policies to the requirements for a balanced sustainable economic development, avoiding environmental risks that imply the violation of human rights. Proportionality in the protection of the interests in this respect creates a context for a fair trial, but also promotes an open and constructive dialogue between judges and lawmakers to protect the public interest.

Getting the science right for the right reasons: the environmental sensing revolution that just happened.

Noting that cool phone in your pocket, and your car have more sensors and wireless capabilities than your new Campbell weather station, does it ever feel like there is a mismatch between the world of science and that of consumer products? How can we understand our place in the "sensing ecosystem," and sort between the transformative opportunities of sensing technology and technological land mines that will expend your budget and be unreliable? Here I review the impact of three technological frameworks on biogeochemical observation: distributed fiber optic sensing; low-power radio and GSM communication; and 3-D printing. From the fiber optic sensing applications in air, soil, rivers, oceans and wells, we see that this truly does qualify as a revolutionary observational platform. Specifically, it densely spans the critical 0.1 m to 10,000 m spatial scales and 1 to 1,000,000 s temporal scales, providing opportunity to address long-standing fundamental open questions. This is placed in contrast to the unfulfilled promises touted by the self-organizing mesh network radio technology. We argue that this outcome reflects a lack of candor of technology insiders in the selling of this technology with respect to the potential given the 1/r^3 energy of radio communication combined with the challenges of environmental settings for wave propagation (e.g., intense rain, snow laden branches, and long periods of low solar radiation). This is contrasted with the excellent outcomes of GSM-based monitoring approaches that leveraged the massive infrastructure of cellular telephones. Finally, I will venture to explain why open-source 3-D printing technology will provide the next transformative opportunity for Biogeosicences by re-inventing point-sensing instrumentation.

Environmental conditions influence the plant functional diversity effect on potential denitrification.

Directory of Open Access Journals (Sweden)

Ariana E Sutton-Grier

2011-02-01

Full Text Available Global biodiversity loss has prompted research on the relationship between species diversity and ecosystem functioning. Few studies have examined how plant diversity impacts belowground processes; even fewer have examined how varying resource levels can influence the effect of plant diversity on microbial activity. In a field experiment in a restored wetland, we examined the role of plant trait diversity (or functional diversity, (FD and its interactions with natural levels of variability of soil properties, on a microbial process, denitrification potential (DNP. We demonstrated that FD significantly affected microbial DNP through its interactions with soil conditions; increasing FD led to increased DNP but mainly at higher levels of soil resources. Our results suggest that the effect of species diversity on ecosystem functioning may depend on environmental factors such as resource availability. Future biodiversity experiments should examine how natural levels of environmental variability impact the importance of biodiversity to ecosystem functioning.

Weighing environmental externalities: How to do it right

International Nuclear Information System (INIS)

Freeman, A.M. III; Burtraw, D.; Harrington, W.; Krupnick, A.J.

1992-01-01

In this paper, the authors focus on the procedure of incorporating monetary measures of external damages as address to private bids and ranking alternatives on the basis of their social costs. They assume that it will be possible to develop methods and models to calculate environmental damages for specific electricity supply options. They reject the use of marginal control cost as a proxy for marginal damages. The question they address here is whether the marginal damage from an increase in electricity supply is the correct adjustment or adder to private cost for least-cost utility planning. They show that arriving at the correct adder depends on both the form that the existing environmental regulations take - that is, whether pollution is controlled by taxation, tradable emissions permits, or direct regulation - and, in the case of an emissions tax, whether the degree of control of pollution is optimal, too strict, or not strict enough according to the criterion of economic efficiency. They make explicit the circumstances under which the correct adder will be equal to marginal damages, will be some other positive number, or zero, or even negative. If emissions reductions are achieved by direct regulation or command and control policies (CAC), then the correct adder is always just equal to marginal damages

Environmental efficiency of energy, materials, and emissions.

This study estimates the environmental efficiency of international listed firms in 10 worldwide sectors from 2007 to 2013 by applying an order-m method, a non-parametric approach based on free disposal hull with subsampling bootstrapping. Using a conventional output of gross profit and two conventional inputs of labor and capital, this study examines the order-m environmental efficiency accounting for the presence of each of 10 undesirable inputs/outputs and measures the shadow prices of each undesirable input and output. The results show that there is greater potential for the reduction of undesirable inputs rather than bad outputs. On average, total energy, electricity, or water usage has the potential to be reduced by 50%. The median shadow prices of undesirable inputs, however, are much higher than the surveyed representative market prices. Approximately 10% of the firms in the sample appear to be potential sellers or production reducers in terms of undesirable inputs/outputs, which implies that the price of each item at the current level has little impact on most of the firms. Moreover, this study shows that the environmental, social, and governance activities of a firm do not considerably affect environmental efficiency. Copyright © 2015 Elsevier Ltd.

McMullen, Cheryl; Eastwood, Ashley; Ward, Jeanette

2016-04-01

To determine local values for environmental attributable fractions and explore their applicability and potential for public health advocacy. Using World Health Organization (WHO) values for environmental attributable fractions, responses from a practitioner survey (73% response rate) were considered by a smaller skills-based panel to determine consensus values for Kimberley environmental attributable fractions (KEAFs). Applied to de-identified data from 17 remote primary healthcare facilities over two years, numbers and proportions of reasons for attendance directly attributable to the environment were calculated for all ages and children aged 0-4 years, including those for Aboriginal patients. Of 150,357 reasons for attendance for patients of all ages, 31,775 (21.1%) were directly attributable to the environment. The proportion of these directly due to the environment was significantly higher for Aboriginal patients than others (23.1% v 14.6%; penvironmental factors, 20% of total primary healthcare demand could be prevented and, importantly, some 25% of presentations by Aboriginal children. KEAFs have potential to monitor impact of local environmental investments. © 2015 Public Health Association of Australia.

Potential Environmental Benefits from Increased Use of Bioenergy in China

Fan, Shuyang; Freedman, Bill; Gao, Jixi

2007-09-01

Because of its large population and rapidly growing economy, China is confronting a serious energy shortage and daunting environmental problems. An increased use of fuels derived from biomass could relieve some demand for nonrenewable sources of energy while providing environmental benefits in terms of cleaner air and reduced emissions of greenhouse gases. In 2003, China generated about 25.9 × 108 metric tons of industrial waste (liquid + solid), 14.7 × 108 metric tons/year (t/y) of manure (livestock + human), 7.1 × 108 t/y of crop residues and food-processing byproducts, 2 × 108 t/y of fuelwood and wood manufacturing residues, and 1.5 × 108 t/y of municipal waste. Biofuels derived from these materials could potentially displace the use of about 4.12 × 108 t/y of coal and 3.75 × 106 t/y of petroleum. An increased bioenergy use of this magnitude would help to reduce the emissions of key air pollutants: SO2 by 11.6 × 106 t/y, NOX by 1.48 × 106 t/y, CO2 by 1.07 × 109 t/y, and CH4 by 50 × 106 t/y. The reduced SO2 emissions would be equivalent to 54% of the national emissions in 2003, whereas those for CO2 are 30%. It is important to recognize, however, that large increases in the use of biomass fuels also could result in socioeconomic and environmental problems such as less production of food and damage caused to natural habitats.

As globalisation has opened remote parts of the world to foreign investment, global leaders at the United Nations and beyond have called on multinational companies to foresee and mitigate negative impacts on the communities surrounding their overseas operations. This movement towards corporate impact assessment began with a push for environmental and social inquiries. It has been followed by demands for more detailed assessments, including health and human rights. In the policy world the two have been joined as a right-to-health impact assessment. In the corporate world, the right-to-health approach fulfils neither managers' need to comprehensively understand impacts of a project, nor rightsholders' need to know that the full suite of their human rights will be safe from violation. Despite the limitations of a right-to-health tool for companies, integration of health into human rights provides numerous potential benefits to companies and the communities they affect. Here, a detailed health analysis through the human rights lens is carried out, drawing on a case study from the United Republic of Tanzania. This paper examines the positive and negative health and human rights impacts of a corporate operation in a low-income setting, as viewed through the human rights lens, considering observations on the added value of the approach. It explores the relationship between health impact assessment (HIA) and human rights impact assessment (HRIA). First, it considers the ways in which HIA, as a study directly concerned with human welfare, is a more appropriate guide than environmental or social impact assessment for evaluating human rights impacts. Second, it considers the contributions HRIA can make to HIA, by viewing determinants of health not as direct versus indirect, but as interrelated.

Punishability of transfrontier environmental offences

1989-01-01

National environmental Acts include a great number of areas and this applies even more if there is an international component. It is not only the German international criminal law but also questions of general criminal law dogmatic and the relationship between environmental criminal law and administrative law that must be taken into account. In order to prevent inadmissible interferences with another country's sovereign rights it is necessary to harmonize the international environmental law and the international environmental criminal law. Aspects of the international civil law and the administrative law have to be considered as well. The book concludes that even abstract offences that carry the potential of endangerment also qualify as statutorily proscribed harm. The German environmental criminal law is therefore applicable even if the offence cause only a domestic danger. An action which is permissible under another country's administrative law is not punishable under some few regulations. In all other cases it is punishable unless the foreign country's Sovereign Act is recognised. This applies if the Federal Republic of Germany has to tolerate harm under international environmental law. Claims under international law to refrain from transformer pollution can often be much more extensive than commonly assumed. (orig.) [de

Exercise and the right ventricle: a potential Achilles' heel.

Science.gov (United States)

La Gerche, Andre; Rakhit, Dhrubo J; Claessen, Guido

2017-10-01

Exercise is associated with unequivocal health benefits and results in many structural and functional changes of the myocardium that enhance performance and prevent heart failure. However, intense exercise also presents a significant hemodynamic challenge in which the right-sided heart chambers are exposed to a disproportionate increase in afterload and wall stress that can manifest as myocardial fatigue or even damage if intense exercise is sustained for prolonged periods. This review focuses on the physiological factors that result in a disproportionate load on the right ventricle during exercise and the long-term consequences. The changes in cardiac structure and function that define 'athlete's heart' disproportionately affect the right-sided heart chambers and this can raise important diagnostic overlap with some cardiac pathologies, particularly some inherited cardiomyopathies. The interaction between exercise and arrhythmogenic right ventricular cardiomyopathy (ARVC) will be highlighted as an important example of how hemodynamic stressors can combine with deficiencies in cardiac structural elements to cause cardiac dysfunction predisposing to arrhythmias. The extent to which extreme exercise can cause adverse remodelling in the absence of a genetic predisposition remains controversial. In the athlete with profound changes in heart structure, it can be extremely challenging to determine whether common symptoms such as palpitations may be a marker of more sinister arrhythmias. This review discusses some of the techniques that have recently been proposed to identify pathology in these circumstances. Finally, we will discuss recent evidence defining the role of exercise restriction as a therapeutic intervention in individuals predisposed to arrhythmogenic cardiomyopathy.

2012-01-01

Navigation infrastructure such as channels, jetties, river training structures, and lock-and-dam facilities are primary components of a safe and efficient water transportation system. Planning for such infrastructure has until recently involved efforts to minimize impacts on the environment through a standardized environmental assessment process. More recently, consistent with environmental sustainability concepts, planners have begun to consider how such projects can also be constructed with environmental enhancements. This study examined the existing institutional conditions within the US Army Corps of Engineers and cooperating federal agencies relative to incorporating environmental enhancements into navigation infrastructure projects. The study sought to (1) investigate institutional attitudes towards the environmental enhancement of navigation infrastructure (EENI) concept, (2) identify potential impediments to implementation and solutions to such impediments, (3) identify existing navigation projects designed with the express intent of enhancing environmental benefit in addition to the primary project purpose, (4) identify innovative ideas for increasing environmental benefits for navigation projects, (5) identify needs for additional technical information or research, and (6) identify laws, regulations, and policies that both support and hinder such design features. The principal investigation tool was an Internet-based survey with 53 questions. The survey captured a wide range of perspectives on the EENI concept including ideas, concerns, research needs, and relevant laws and policies. Study recommendations included further promotion of the concept of EENI to planners and designers, documentation of existing projects, initiation of pilot studies on some of the innovative ideas provided through the survey, and development of national goals and interagency agreements to facilitate implementation.

Comparison of exergy of emissions from two energy conversion technologies, considering the potential for environmental impact

Crane, P.; Scott, D.S.; Rosen, M.A.

1992-01-01

There is a reference state in which substances exist in a stable form in the environment (atmosphere, hydrosphere, lithosphere) for all elements. Substances which are out of equilibrium with the environmental reference state, either in terms of chemical composition, concentration, pressure or temperature represent an opportunity to do work as they pass through processes which bring them to the environmental reference state and hence into equilibrium with the environment. The degree to which a substance is out of equilibrium with the environment is represented by its exergy. For an unconstrained emission, the exergy, or potential to do work, of a substance is dissipated in the environment as the substance is brought to the reference state of the environment. Hence, exergy may be considered a measure of the potential of the substance to impact the environment. This paper examines emissions from two alternate automobile power trains: (i) methanol-fuelled spark ignition engines, and (ii) hydrogen-fuelled fuel cells. It is shown that the exergy of emissions from the methanol engine is high (and thus indicative of greater impact on the environment), whereas emissions from a hydrogen/air fuel cell are lower in exergy (thus indicating a system better synchronised with the environment). These results are as expected. Thus, the methodology presented for evaluation of potential for environmental impact, which is both general and quantitative, appears promising. (Author)

Variations in Environmental Signals in Tree-Ring Indices in Trees with Different Growth Potential.

Directory of Open Access Journals (Sweden)

Polona Hafner

Full Text Available We analysed two groups of Quercus robur trees, growing at nearby plots with different micro-location condition (W-wet and D-dry in the floodplain Krakovo forest, Slovenia. In the study we compared the growth response of two different tree groups to environmental variables, the potential signal stored in earlywood (EW structure and the potential difference of the information stored in carbon isotope discrimination of EW and latewood (LW. For that purpose EW and LW widths and carbon isotope discrimination for the period 1970-2008 AD were measured. EW and LW widths were measured on stained microscopic slides and chronologies were standardised using the ARSTAN program. α-cellulose was extracted from pooled EW and LW samples and homogenized samples were further analysed using an elemental analyser and IRMS. We discovered that W oaks grew significantly better over the whole analysed period. The difference between D and W oaks was significant in all analysed variables with the exception of stable carbon isotope discrimination in latewood. In W oaks, latewood widths correlated with summer (June to August climatic variables, while carbon isotope discrimination was more connected to River Krka flow during the summer. EW discrimination correlated with summer and autumn River Krka flow of the previous year, while latewood discrimination correlated with flow during the current year. In the case of D oaks, the environmental signal appears to be vague, probably due to less favourable growth conditions resulting in markedly reduced increments. Our study revealed important differences in responses to environmental factors between the two oak groups of different physiological conditions that are preconditioned by environmental stress. Environmental information stored in tree-ring features may vary, even within the same forest stand, and largely depends on the micro-environment. Our analysis confirmed our assumptions that separate EW and LW analysis of widths and

This paper examines how stakeholder demand and compliance capacity jointly shape corporate environmental coping strategies and subsequently environmental protection practices. A four-dimensional classification of coping strategies-formalism, accommodation, referencing, and self-determination-is conceptualized. Drawing on survey and interview data collected from manufacturing enterprises in China between 2010 and 2012, the paper shows that compared with formalism and accommodation, coping strategies of referencing and self-determination are associated with stronger environmental protection practices. Enterprises adjust their coping strategies by taking into account the constraints defined by both their internal and external environments. The results also demonstrate the potential synergetic effects of state and non-state stakeholders working together in promoting better corporate environmental coping strategies and environmental practices in China.

Potential environmental impacts of light-emitting diodes (LEDs): metallic resources, toxicity, and hazardous waste classification.

Science.gov (United States)

Lim, Seong-Rin; Kang, Daniel; Ogunseitan, Oladele A; Schoenung, Julie M

2011-01-01

Light-emitting diodes (LEDs) are advertised as environmentally friendly because they are energy efficient and mercury-free. This study aimed to determine if LEDs engender other forms of environmental and human health impacts, and to characterize variation across different LEDs based on color and intensity. The objectives are as follows: (i) to use standardized leachability tests to examine whether LEDs are to be categorized as hazardous waste under existing United States federal and California state regulations; and (ii) to use material life cycle impact and hazard assessment methods to evaluate resource depletion and toxicity potentials of LEDs based on their metallic constituents. According to federal standards, LEDs are not hazardous except for low-intensity red LEDs, which leached Pb at levels exceeding regulatory limits (186 mg/L; regulatory limit: 5). However, according to California regulations, excessive levels of copper (up to 3892 mg/kg; limit: 2500), Pb (up to 8103 mg/kg; limit: 1000), nickel (up to 4797 mg/kg; limit: 2000), or silver (up to 721 mg/kg; limit: 500) render all except low-intensity yellow LEDs hazardous. The environmental burden associated with resource depletion potentials derives primarily from gold and silver, whereas the burden from toxicity potentials is associated primarily with arsenic, copper, nickel, lead, iron, and silver. Establishing benchmark levels of these substances can help manufacturers implement design for environment through informed materials substitution, can motivate recyclers and waste management teams to recognize resource value and occupational hazards, and can inform policymakers who establish waste management policies for LEDs.

Environmentally induced epigenetic toxicity: potential public health concerns.

Marczylo, Emma L; Jacobs, Miriam N; Gant, Timothy W

2016-09-01

Throughout our lives, epigenetic processes shape our development and enable us to adapt to a constantly changing environment. Identifying and understanding environmentally induced epigenetic change(s) that may lead to adverse outcomes is vital for protecting public health. This review, therefore, examines the present understanding of epigenetic mechanisms involved in the mammalian life cycle, evaluates the current evidence for environmentally induced epigenetic toxicity in human cohorts and rodent models and highlights the research considerations and implications of this emerging knowledge for public health and regulatory toxicology. Many hundreds of studies have investigated such toxicity, yet relatively few have demonstrated a mechanistic association among specific environmental exposures, epigenetic changes and adverse health outcomes in human epidemiological cohorts and/or rodent models. While this small body of evidence is largely composed of exploratory in vivo high-dose range studies, it does set a precedent for the existence of environmentally induced epigenetic toxicity. Consequently, there is worldwide recognition of this phenomenon, and discussion on how to both guide further scientific research towards a greater mechanistic understanding of environmentally induced epigenetic toxicity in humans, and translate relevant research outcomes into appropriate regulatory policies for effective public health protection.

Potential environmental effects of fusion reactor power plants

International Nuclear Information System (INIS)

Young, J.R.; Gore, B.F.; Coffman, F.E.

1976-01-01

Construction and operation of fusion power plants is expected to reduce the total environmental effects of 21st century power generation. Fusion power plant impacts due to noise, odors, vibrations, and sanitary wastes are expected to be insignificant. impacts due to land use, chemical releases, and aesthetics are expected to be reduced. Impacts due to heat releases, local socio-economic changes, and non-radioactive liquid and solid disposal are expected to be comparable to those for the alternative fission or coal-fired power systems. Radiation doses to the public due to radioactive wastes are expected to be comparable to, or less than, the trivial low doses due to fission power systems. Research and development will be required, however, to assure adequate containment of tritium, the primary radioisotope of concern. Prevention of accidental tritium releases is within the capability of current engineering practice. Current technology is capable of handling the solid radioactive waste which may be produced, with insignificant environmental impact. Major research efforts are necessary to determine if subtle long-term effects of magnetic fields exist and should be of concern. In view of the large quantities of construction materials required for fusion. Material availability may dictate 21st century power plant design and construction. The accident potential of fusion power plants should be lower than for fission systems. Accidental criticalities and plasma runaways are not considered to be possible. Loss of coolant accidents are not expected to result in damage to the containment. No fission products or actinides are present to be released in an accident, and most activation products are immobilized in structures. The biological hazard of tritium is orders of magnitude smaller than for fission products and actinides. Safeguards against diversion of fissile materials are not expected to be necessary

Wavelet analysis as a tool to characteriseand remove environmental noisefrom self-potential time series

Directory of Open Access Journals (Sweden)

M. Ragosta

2004-06-01

Full Text Available Multiresolution wavelet analysis of self-potential signals and rainfall levels is performed for extracting fluctuations in electrical signals, which might be addressed to meteorological variability. In the time-scale domain of the wavelet transform, rain data are used as markers to single out those wavelet coefficients of the electric signal which can be considered relevant to the environmental disturbance. Then these coefficients are filtered out and the signal is recovered by anti-transforming the retained coefficients. Such methodological approach might be applied to characterise unwanted environmental noise. It also can be considered as a practical technique to remove noise that can hamper the correct assessment and use of electrical techniques for the monitoring of geophysical phenomena.

Coal and nuclear wastes: both potential contributors to environmental and health problems

International Nuclear Information System (INIS)

1981-01-01

The Chairman, Subcommittee on Energy Conservation and Power, House Committee on Energy and Commerce, asked GAO to answer eight questions regarding waste produced by coal and nuclear fuels during the generation of electricity. This report primarily discusses the first two items in the Chairman's request: what are the types and quantities of wastes generated at each step of the coal and nuclear fuel cycles. What are the health and environmental problems associated with these wastes. Based on a comprehensive literature search GAO found that wastes produced by both the coal and nuclear fuel cycles present the potential for significant environmental and health hazards. Because the waste types present different types of hazards, however, it is not possible to determine if either waste type is more of a hazard than the other. Nonetheless, most of the hazards from both fuel cycles can be lessened, or in some cases eliminated, if properly controlled and regulated

Environment and economy: Property rights and public policy

International Nuclear Information System (INIS)

Bromley, D.J.

1991-01-01

For much of its history, environmental economics has sought to modify public policy in order to achieve efficient use and management of environmental resources. The results of this attempt, however, have been dismaying for the most part, and environment public policy continues to differ from the course of action prescribed by economic analysis. Some economists have begun to acknowledge that the reasons for this gap between economic theory and public policy may lie in environmental economics itself rather than in poor policy choices. That is the message sent in this book by Daniel Bromley, who joins S.V. Ciriacy-Wantrup, Allan Schmid, and others in a strong internal critique of the discipline and, in particular, of the 'property rights school' of Coase, Demsetz, and other advocates of the market. Property rights are the common thread of this critique, which blames much of the failure of environmental economics to influence environmental policy on several fundamental misconceptions regarding property

Potential Environmental and Human Health Impacts of Rechargeable Lithium Batteries in Electronic Waste

Kang, Daniel Hsing Po; Chen, Mengjun; Ogunseitan, Oladele A.

2013-01-01

Rechargeable lithium-ion (Li-ion) and lithium-polymer (Li-poly) batteries have recently become dominant in consumer electronic products because of advantages associated with energy density and product longevity. However, the small size of these batteries, the high rate of disposal of consumer products in which they are used, and the lack of uniform regulatory policy on their disposal means that lithium batteries may contribute substantially to environmental pollution and adverse human health impacts due to potentially toxic materials. In this research, we used standardized leaching tests, life-cycle impact assessment (LCIA), and hazard assessment models to evaluate hazardous waste classification, resource depletion potential, and toxicity potentials of lithium batteries used in cellphones. Our results demonstrate that according to U.S. federal regulations, defunct Li-ion batteries are classified hazardous due to their lead (Pb) content (average 6.29 mg/L; σ = 11.1; limit 5). However, according to California regulations, all lithium batteries tested are classified hazardous due to excessive levels of cobalt (average 163 544 mg/kg; σ = 62 897; limit 8000), copper (average 98 694 mg/kg; σ = 28 734; limit 2500), and nickel (average 9525 mg/kg; σ = 11 438; limit 2000). In some of the Li-ion batteries, the leached concentrations of chromium, lead, and thallium exceeded the California regulation limits. The environmental impact associated with resource depletion and human toxicity is mainly associated with cobalt, copper, nickel, thallium, and silver, whereas the ecotoxicity potential is primarily associated with cobalt, copper, nickel, thallium, and silver. However, the relative contribution of aluminum and lithium to human toxicity and ecotoxicity could not be estimated due to insufficient toxicity data in the models. These findings support the need for stronger government policy at the local, national, and international levels to encourage recovery, recycling, and

Improving the Sustainability of Transportation: Environmental and Functional Benefits of Right Turn By-Pass Lanes at Roundabouts

Marco Guerrieri

2015-05-01

Full Text Available The functional performances of conventional roundabouts (single-lane and multi-lane and innovative roundabouts (spiral, flower, C and turbo can be improved through right-turn bypass lanes controlled by stop, yield or free-flow signs. The article presents evaluations of the emissions of air pollutants (carbon dioxide, nitrogen oxides, particle pollution (PM10 and PM2.5, fuel consumption and construction, management, energetic and environmental costs in roundabouts without or with bypass lanes (controlled by stop, yield or free-flow. The suggested methodology has a general character and can be applied as a multi-parametric criterion for choosing road intersections, although, in the present paper, it has been employed only for a case study. For the aims of this research, we employed recent closed-form formulations to determine roundabout performances; moreover, we used the COPERT IV® software to estimate air emissions in nine different types of vehicles. Numerous traffic simulations were carried out. The variation in the maximum hourly traffic Qmax and annual traffic QTOT provided the appropriate domains of the examined geometric layouts, both in functional and environmental terms and with regard to generalized costs, estimated for a 10-year period. It resulted that the introduction of right-turn bypasses in all arms of conventional roundabouts with a one ring lane and one lane at the entries (single-lane roundabouts is the most cost-effective when the flows entering the roundabout are higher than Qmax = 2000 veh/h. Moreover, free-flow bypass lanes always provide greater capacity and lower delays than stop- or yield-signaled bypasses. However, with extremely high Qmax values, stop-controlled bypasses guarantee lower fuel consumption, while those with a yield sign lower total costs.

Fighting ambient air pollution and its impact on health: from human rights to the right to a clean environment.

Science.gov (United States)

Guillerm, N; Cesari, G

2015-08-01

Clean air is one of the basic requirements of human health and well-being. However, almost nine out of 10 individuals living in urban areas are affected by air pollution. Populations living in Africa, South-East Asia, and in low- and middle-income countries across all regions are the most exposed. Exposure to outdoor air pollution ranks as the ninth leading risk factor for mortality, killing 3.2 million people each year, especially young children, the elderly, persons with lung or cardiovascular disease, those who work or exercise outdoors and low-income populations. In October 2013, the International Agency for Research on Cancer (IARC) classified outdoor air pollution as carcinogenic to humans, calling air pollution 'a major environmental health problem'. Human rights and environmental norms are powerful tools to combat air pollution and its impact on health. The dependence of human rights on environmental quality has been recognised in international texts and by human rights treaty bodies. The growing awareness of the environment has already yielded considerable legislative and regulatory output. However, the implementation of standards remains a pervasive problem. In the fight against violations of norms, citizens have a crucial role to play. We discuss the relevance of a yet to be proclaimed standalone right to a healthy environment.

Transmission rights and market power

International Nuclear Information System (INIS)

Bushnell, J.

1999-01-01

Most of the concerns about physical transmission rights relate to the ability to implicitly or explicitly remove that transmission capacity from the market-place. Under a very strict form of physical right, owners could simply choose not to sell it if they don't want to use it. Modifications that require the release of spare capacity back into an open market could potentially alleviate this problem but there is concern that such releases would not occur far enough in advance to be of much use to schedulers. Similarly, the transmission capacity that is made available for use by non-rights holders can also be manipulated by the owners of transmission rights. The alternative form, financial transmission rights, provide to their owners congestion payments, but physical control of transmission paths. In electricity markets such as California's, even financial transmission rights could potentially be utilized to effectively withhold transmission capacity from the marketplace. However, methods for withholding transmission capacity are somewhat more convoluted, and probably more difficult, for owners of financial rights than for owners of physical rights. In this article, the author discusses some of the potential concerns over transmission rights and their use for the exercise of various forms of market power

After the development of a working definition of ''environmental refugees'', the study examines existing State obligations in international law (obligations of the State of origin and of third States under human rights law and general public international law), which are relevant for the prevention of ''environmental flight'' as well as for coping with situations of ''environmental flight'' and identifies shortcomings. In a second step and based on this inventory and gap analysis, a catalogue of ''ideal'' State obligations and individual rights aiming at the best possible protection for (potential) ''environmental refugees'' is created. After comparing the advantages and disadvantages of different solution models, a specific, ''ideal'' solution is presented. (orig.)

Potential environmental and regulatory implications of naturally occurring radioactive materials (NORM)

International Nuclear Information System (INIS)

Paschoa, A.S.

1998-01-01

The immense volume of naturally occurring radioactive materials (NORM) wastes produced annually by extracting industries throughout the world deserves to come to the attention of international and national environmental protection agencies and regulatory bodies. Although a great deal of work has been done in the fields of radiation protection and remedial actions concerning uranium and other mines, the need to dispose of diffuse NORM wastes will have environmental and regulatory implications that thus far are not fully appreciated. NORM wastes constitute, by and large, unwanted byproducts of industrial activities as diverse as thorium and uranium milling, niobium, tin and gold mining extraction, water treatment, and the production of oil, gas, phosphate fertilizer, coal fire and aluminium. The volumes of NORM wastes produced annually could reach levels so high that the existing low level radioactive waste (LLRW) facilities would be readily occupied by NORM if controlled disposal procedures were not adopted. On the other hand, NORM cannot just be ignored as being below radiological concern (BRC) or lower than exempt concentration levels (ECLs), because sometimes NORM concentrations reach levels as high as 1 x 10 3 kBq/kg for 226 Ra, and not much less for 228 Ra. Unfortunately, thus far, there is not enough information available concerning NORM wastes in key industries, though the international scientific community has been concerned, for a long time now, with technologically enhanced natural radiation exposures (TENRE). This article is written with the intention of examining, to the extent possible, the potential environmental and regulatory implications of NORM wastes being produced in selected industries.

Full Text Available This article discusses the Right to the City, in a conceptual dimension and wide, and his dialectical relationship with the Universal Declaration of Human Rights of 1948 and its universalism and cultural relativism categories. The Right to the City (RtC is capitula- ted as one of the categories of the Human Right to Development from the compartments on Human Rights to descend from the Universal Declaration of Human Rights. Linked to this assumption, the discussion of universalism and cultural relativism theories bring to the fore important questions and considerations as to RtC condition, since in its current design and trampled by an evil legacy of neoliberalism, this right has demonstrated the need for authoritative action of the State, given the nature of fundamental human right of the third dimension.

Pack and saddle stock, including, but not limited to domesticated horses, mules, and burros, are used to support commercial, private and administrative activities in the Sierra Nevada. The use of pack stock has become a contentious and litigious issue for land management agencies in the region inter alia due to concerns over effects on the environment. The potential environmental effects of pack stock on Sierra Nevada meadow ecosystems are reviewed and it is concluded that the use of pack stock has the potential to influence the following: (1) water nutrient dynamics, sedimentation, temperature, and microbial pathogen content; (2) soil chemistry, nutrient cycling, soil compaction and hydrology; (3) plant individuals, populations and community dynamics, non-native invasive species, and encroachment of woody species; and (4) wildlife individuals, populations and communities. It is considered from currently available information that management objectives of pack stock should include the following: minimise bare ground, maximise plant cover, maintain species composition of native plants, minimise trampling, especially on wet soils and stream banks, and minimise direct urination and defecation by pack stock into water. However, incomplete documentation of patterns of pack stock use and limited past research limits current understanding of the effects of pack stock, especially their effects on water, soils and wildlife. To improve management of pack stock in this region, research is needed on linking measurable monitoring variables (e.g. plant cover) with environmental relevancy (e.g. soil erosion processes, wildlife habitat use), and identifying specific environmental thresholds of degradation along gradients of pack stock use in Sierra Nevada meadows.

Of global concern, environmental pollution adversely affects human health and socioeconomic development. The presence of environmental contaminants, especially bacterial, viral, and parasitic pathogens and their toxins as well as chemical substances, poses serious public health concerns. Nanoparticle-based biosensors are considered as potential tools for rapid, specific, and highly sensitive detection of the analyte of interest (both biotic and abiotic contaminants). In particular, there are several limitations of conventional detection methods for water-borne pathogens due to low concentrations and interference with various enzymatic inhibitors in the environmental samples. The increase of cells to detection levels requires long incubation time. This review describes current state of biosensor nanotechnology, the advantage over conventional detection methods, and the challenges due to testing of environmental samples. The major approach is to use nanoparticles as signal reporter to increase output rather than spending time to increase cell concentrations. Trends in future development of novel detection devices and their advantages over other environmental monitoring methodologies are also discussed. PMID:25884032

Health and environmental groups have filed a request with the Ontario Ministry of Environment and Ministry of Energy to review its government policies on transboundary smog, mercury emissions and climate change in light of the abandonment of plans to close all of the province's highly polluting coal-fired power plants by 2009. The groups have requested that the Ministries identify the measures that will be taken to eliminate the health, social and environmental impacts caused by this decision. The representatives of Ontario's registered nurses, physicians, community groups and environment groups want to know how the decision will affect Ontario's compliance with the terms of the Ozone Annex to the 1991 United States-Canada Air Quality Agreement, Ontario's compliance with the proposed Canada Wide Standard on Mercury, and efforts to combat climate change. Concerns that the government has weakened its position in dealing with the United States over transboundary smog were expressed. Smog, climate change and mercury pollution pose significant risks to the health of Ontarians. The original plan to replace coal-fired generation was the single largest greenhouse gas reduction initiative in Canada. It was argued that the abandonment of that plan represents a major challenge in meeting Kyoto targets. refs

Highlights: • A waste-to-energy system is constructed incorporating various urban wastes and technologies. • Waste-to-energy industries are formed and introduced into current socioeconomic system. • A novel input–output simulation model is developed and applied to a metropolis. • Complete energy, economic and environmental potentials of urban wastes are discovered. - Abstract: Tremendous amounts of wastes are generated in urban areas due to accelerating industrialization and urbanization. The current unreasonable waste disposal patterns and potential energy value of urban wastes necessitates the promotion of waste-to-energy implementation. This study is intent on discovering the complete energy, economic and environmental potentials of urban wastes taking municipal solid wastes, waste oil, organic wastewater and livestock manure into consideration. A waste-to-energy system is constructed incorporating these wastes and five waste-to-energy technologies. A novel input–output simulation model is developed and applied to a metropolis to introduce the waste-to-energy system into the current socioeconomic system and form five waste-to-energy industries. The trends in waste generation and energy recovery potential, economic benefits and greenhouse gas mitigation contribution for the study area are estimated and explored from 2011 to 2025. By 2025, biodiesel production and power generation could amount to 72.11 thousand t and 1.59 billion kW h respectively. Due to the highest energy recovery and the most subsidies, the organic wastewater biogas industry has the highest output and net profit, followed by the waste incineration power generation industry. In total 17.97 million t (carbon dioxide-equivalent) accumulative greenhouse gas emission could be mitigated. The organic wastewater biogas industry and waste incineration power generation industry are more advantageous for the study area in terms of better energy, economic and environmental performances.

Restall, Brian; Conrad, Elisabeth

2015-08-15

Understanding how people's relationships with nature form, how they influence personal values and attitudes, and what behavioural implications they may have could provide more insight into how connectedness to nature (CNT) can effectively contribute to environmental management goals. This paper undertakes a review of literature published over the past decade (2002-2011) on SCOPUS; and describes the current state of knowledge regarding CNT, assesses any efforts towards the spatial mapping of CNT for environmental management, and identifies measures of CNT defined in the broader literature. This review suggests that there is quite some overlap in the literature on CNT concepts, and that more effort needs to be made towards multi-disciplinary research which explores how CNT can be useful to environmental planning and conservation research on the field. It also further corroborates the need and relevance of applying more social and affective strategies to promote conservation behaviour. The main progress in CNT theory seems to have been made in the development of measurement tools, and it is clear that there is a strong convergent validity amongst the different measures due to their similarity, and functional associations. Further efforts towards the exploration of multi-dimensional measures is recommended since they consistently stand out as showing better results. The geographic visualisation of CNT constructs is another area of research that deserves attention since it can provide a unique point of view towards guiding participatory protected area planning and management.

Potential to curb the environmental burdens of American beef consumption using a novel plant-based beef substitute.

Directory of Open Access Journals (Sweden)

Benjamin Goldstein

Full Text Available The food demands of the United States (US impart significant environmental pressures. The high rate of consumption of beef has been shown to be the largest driver of food-borne greenhouse gas emissions, water use and land occupation in the US diet. The environmental benefits of substituting animal products with vegetal foods are well documented, but significant psychological barriers persist in reducing meat consumption. Here we use life cycle assessment to appraise the environmental performance of a novel vegetal protein source in the mean US diet where it replaces ground beef, and in vegetarian and vegan diets where it substitutes for legumes, tofu and other protein sources. We find that relative to the mean US diet, vegetarian and vegan diets significantly reduce per-capita food-borne greenhouse gas emission (32% and 67%, respectively, blue water use (70% and 75%, respectively and land occupation (70% and 79%, respectively, primarily in the form of rangeland. The substitution of 10%, 25% and 50% of ground beef with plant-based burger (PBB at the national scale results in substantial reductions in annual US dietary greenhouse gas emissions (4.55-45.42 Mt CO2 equivalents, water consumption (1.30-12.00 km3 and land occupation (22300-190100 km2. Despite PBB's elevated environmental pressures compared to other vegetal protein sources, we demonstrate that minimal risk exists for the disservices of PBB substitution in non-meat diets to outweigh the benefits of ground-beef substitution in the omnivorous American diet. Demand for plant-based oils in PBB production has the potential to increase land use pressures in biodiversity hotspots, though these could be obviated through responsible land stewardship. Although the apparent environmental benefits of the PBB are contingent on actual uptake of the product, this study demonstrates the potential for non-traditional protein substitutes to play a role in a transition towards more sustainable consumption

The right to health of prisoners in international human rights law.

Lines, Rick

2008-01-01

This paper explores the health rights of prisoners as defined in international law, and the mechanisms that have been used to ensure the rights of persons in detention to realise the highest attainable standard of health. It examines this right as articulated within United Nations and regional human rights treaties, non-binding or so-called soft law instruments from international organisations and the jurisprudence of international human rights bodies. It explores the use of economic, social and cultural rights mechanisms, and those within civil and political rights, as they engage the right to health of prisoners, and identifies the minimum legal obligations of governments in order to remain compliant with human rights norms as defined within the international case law. In addressing these issues, this article adopts a holistic approach to the definition of the highest attainable standard of health. This includes a consideration of adequate standards of general medical care, including preventative health and mental health services. It also examines the question of environmental health, and those poor conditions of detention that may exacerbate health decline, disease transmission, mental illness or death. The paper examines the approach to prison health of the United Nations human rights system and its various monitoring bodies, as well as the regional human rights systems in Europe, Africa and the Americas. Based upon this analysis, the paper draws conclusions on the current fulfilment of the right to health of prisoners on an international scale, and proposes expanded mechanisms under the UN Convention against Torture and Other Cruel, Inhuman or Degrading Treatment to monitor and promote the health rights of prisoners at the international and domestic levels.

The environmental justice movement has come a long way since its birth a decade ago in rural and mostly African American Warren County, North Carolina. The selection of Warren County for a PCB landfill, they brought national attention to waste facility siting inequities and galvanized African American church and civil rights leaders` support for environmental justice. The demonstrations also put {open_quotes}environmental racism{close_quotes} on the map and challenged the myth that African Americans are not concerned about or involved in environmental issues. Grassroots groups, after decades of struggle, have grown to become the core of the multi-issue, multiracial, and multi-regional environmental justice movement. Diverse community-based groups have begun to organize and link their struggles to issues of civil and human rights, land rights and sovereignty, cultural survival , racial and social justice, and sustainable development. The impetus for getting environmental justice on the nations`s agenda has come from an alliance of grassroots activists, civil rights leaders, and a few academicians who questioned the foundation of the current environmental protection paradigm--where communities of color receive unequal protection. Whether urban ghettos and barrios, rural {open_quotes}poverty pockets,{close_quotes} Native American reservations, or communities in the Third World, grassroots groups are demanding an end to unjust and nonsustainable environmental and development policies.

2013-03-01

Full Text Available Within the frameworks of the author’s concept of the potential of an enterprise as the ability to conduct its immanently appropriate activity and also the idea of presentation of the size of the potential in the form of potential function from parameters of the state of an enterprise and foreign economic environment the article develops a scientific and methodical approach to construction and analysis of the potential function of an enterprise. The offered approach envisages building an economic and mathematical model of an enterprise of the optimisation type with consideration of environmental factors, determination of the size of economic potential as a maximum possible (optimal with the set condition of an enterprise and external environment of net income, statistical test of the model with possible values of external parameters (formation of statistical sampling of the graph of the potential function of an enterprise and application of statistical methods including methods of correlation, factor and regression analysis, for the study of its properties. Operability of this approach is shown on the example of the study of properties of the potential function of a model enterprise. In the course of approbation the article demonstrates its ability to reveal specific features of impact of external factors on economic potential of an enterprise; establishes, as a common regularity, differential influence of various environmental factors, caused not only by the nature of these factors, but also production and economic specific features and specific state of an enterprise. The article shows that the quantitative values of the force of influence of the said factors upon the value of economic potential, obtained during statistical analysis of the potential function of an enterprise, could serve as an instrument of ranking these factors by the priority level in the goal setting tasks at the stage of formation of the strategy of enterprise development

Using Constitutional Provisions to Advance Environmental Justice – Some Reflections on Sri Lanka

Directory of Open Access Journals (Sweden)

Camena Guneratne

2015-09-01

Full Text Available This paper examines the principle of environmental justice and its potential applicability to developing countries such as Sri Lanka. It first considers the interpretation and application of the principle in its country of origin, the United States, where it is used primarily to address problems of discrimination in the context of pollution. The paper takes the view that while such an interpretation of environmental justice is valid in this particular context, it cannot address issues of environment and development that arise in countries of the global South, which are grappling with development processes. These processes give rise to issues that may be subject to judicial determination, including sustainable development, protection of natural resources, human rights and social equity. The principle must therefore be re-interpreted to encompass all these dimensions. This paper argues that such an expansion and implementation of the principle of environmental justice in a context of environment and development in countries such as Sri Lanka, is most effective within a constitutional framework of human rights. Constitutions provide both the substantive and procedural foundation of rights, which are interpreted, enforced and given validity at the highest level of the judicial process. Even where environmental rights per se are not contained in a constitution, the existing rights can be, and have been, re-formulated to address issues of environment and development and related human rights. This paper analyses constitutional rights in Sri Lanka, which although limited in scope, has nevertheless formed the basis of a wide body of jurisprudence which brings new dimensions to the principle.

1999-01-01

This discussion paper examines physical transmission rights where the capacity of each potentially congested interface is defined and the rights to use the congested interfaces are created and allocated in some way for suppliers and consumers. The way in which the allocation of physical rights affects competition or increases the buyers or sellers market power in the power generation market when a transmission interface is congested, and how rights markets with different microstructures allocate physical rights and determine rights prices are explored. An electricity market with physical transmission rights in the absence of capacity release rules, and physical transmission rights and market power are addressed.

Environmental impacts of micro-wind turbines and their potential to contribute to UK climate change targets

International Nuclear Information System (INIS)

Greening, Benjamin; Azapagic, Adisa

2013-01-01

This paper evaluates the life cycle environmental sustainability of micro-wind turbines in the UK in comparison with grid electricity and solar PV (photovoltaics). The results suggests that per kWh electricity generated, the majority of environmental impacts from the wind turbines are lower than from grid electricity, ranging from 26% lower terrestrial toxicity to 92% lower global warming. However, depletion of abiotic elements, fresh-water and human toxicities are 82%, 74% and 53% higher than for grid electricity, respectively. The wind turbines are more environmentally sustainable than solar PV for seven out of 11 impacts, ranging from 7.5% lower eutrophication to 85% lower ozone layer depletion. However, depletion of fossil resources, fresh-water, human and terrestrial toxicities are higher for the wind turbine than for the PV, ranging from 5% for the former to 87% for the latter. UK-wide deployment of micro-wind turbines would save between 0.6 and 1% of GHG (greenhouse gas) emissions on 2009 levels. Therefore, the potential of micro-wind turbines to contribute towards UK's climate change targets is limited. - Highlights: • Life cycle environmental impacts of micro-wind turbines estimated for UK conditions. • The majority impacts are lower for micro-wind turbines than for grid electricity and solar PV. • Some impacts from micro-wind are higher, notably fresh-water and human toxicity. • At the national level, wind turbines would save only 0.6% GHG emissions on 2009 levels. • The potential of micro-wind turbines to contribute to UK's climate change targets is limited

Potential impacts of nanotechnology on energy transmission applications and needs.

Energy Technology Data Exchange (ETDEWEB)

Elcock, D.; Environmental Science Division

2007-11-30

The application of nanotechnologies to energy transmission has the potential to significantly impact both the deployed transmission technologies and the need for additional development. This could be a factor in assessing environmental impacts of right-of-way (ROW) development and use. For example, some nanotechnology applications may produce materials (e.g., cables) that are much stronger per unit volume than existing materials, enabling reduced footprints for construction and maintenance of electricity transmission lines. Other applications, such as more efficient lighting, lighter-weight materials for vehicle construction, and smaller batteries having greater storage capacities may reduce the need for long-distance transport of energy, and possibly reduce the need for extensive future ROW development and many attendant environmental impacts. This report introduces the field of nanotechnology, describes some of the ways in which processes and products developed with or incorporating nanomaterials differ from traditional processes and products, and identifies some examples of how nanotechnology may be used to reduce potential ROW impacts. Potential environmental, safety, and health impacts are also discussed.

Potential synergies between existing multilateral environmental agreements in the implementation of land use, land-use change and forestry activities

International Nuclear Information System (INIS)

Cowie, Annette; Schneider, Uwe A.; Montanarella, Luca

2007-01-01

There is potential for synergy between the global environmental conventions on climate change, biodiversity and desertification: changes in land management and land use undertaken to reduce net greenhouse gas emissions can simultaneously deliver positive outcomes for conservation of biodiversity, and mitigation of desertification and land degradation. However, while there can be complementarities between the three environmental goals, there are often tradeoffs. Thus, the challenge lies in developing land use policies that promote optimal environmental outcomes, and in implementing these locally to promote sustainable development. The paper considers synergies and tradeoffs in implementing land use measures to address the objectives of the three global environmental conventions, both from an environmental and economic perspective. The intention is to provide environmental scientists and policy makers with a broad overview of these considerations, and the benefits of addressing the conventions simultaneously

Ethics and data protection in human biomarker studies in environmental health.

Casteleyn, Ludwine; Dumez, Birgit; Van Damme, Karel; Anwar, Wagida A

2013-08-01

Human biomarker studies in environmental health are essential tools to study the relationship between health and environment. They should ultimately contribute to a better understanding of environmentally induced adverse health effects and to appropriate preventive actions. To ensure the protection of the rights and dignity of study participants a complex legal and ethical framework is applied, consisting of several international directives, conventions, and guidelines, whether or not translated in domestic laws. Main characteristics of ethics and data protection in studies using biomarkers in the field of environmental health are summarized and current discussions on related questions and bottlenecks highlighted. In the current regulatory context, dominated by the protection of the individual study participant, difficulties are reported due to the different interpretation and implementation of the regulations of concern within and across borders. Advancement of consistency and compatibility is recommended and efforts are ongoing. An increasing demand for secondary use of data and samples poses additional challenges in finding a right balance between the individual rights of the study participants on the one hand and the common interest of, and potential benefit for the public or community at large on the other. Ethics committees could play a key role in assessing problems originating from the sometimes competing needs at individual and societal level. Building trust in science amongst (potential) study participants and within the community allows the inclusion of arguments from the societal perspective. This requires increased attention for respectful communication efforts. Striving for public participation in decision making processes may promote policy relevant research and the related translation of study results into action. Copyright © 2013 Elsevier GmbH.

Potential Application of Environmental Noise Recordings in Geoarchaeological Site Characterization

Science.gov (United States)

Di Luzio, E.

2015-12-01

Environmental noise recordings are commonly applied in seismic microzonation studies. By calculating the H/V spectral ratio, the fundamental frequency of soft terrains overlying a rigid bedrock can be determined (Nakamura (1989). In such a simple two-layer system, equation f = n Vs/4H (1) links the resonance frequency "f" to the thickness "H" and shear waves velocity "Vs "of the resonating layer. In recent years, this methodology has been applied generally to obtain information on the seismostratigraphy of an investigated site in different environmental context. In this work, its potential application in the characterization of archaeological features hosted in shallow geological levels is discussed. Field cases are identified in the Appia Antica archaeological site which is placed in central Italy. Here, acknowledged targets correspond to: i) empty tanks carved by the Romans into Cretaceous limestone in the IV-III cen. BC and ii): the basaltic stone paving of the ancient road track which is locally buried beneath colluvial deposits. Narrowly-spaced recordings of environmental noise were carried using a portable digital seismograph equipped with three electrodynamic orthogonal sensors (velocimeters) responding in the band 0.1 ÷1024 Hz and adopting a sampling frequency of 256 Hz.. Results are discussed in terms of absolute H/V values and related distribution maps in the very high-frequency interval of 10-40Hz. In the tanks hosting area, interpolation of H/V maximum values around 13Hz matches caves location and alignment, which is also evidenced by clear inversions (H/V<1) at lower frequencies (10-1Hz). Correlation between H/V peaks and the top surface of the buried stone paving along the prosecution of the road track is even more straightforward. Finally, the depth variations of the tank roofs and the basaltic paving were reconstructed combining in equation (1) results of noise recordings with borehole data and geophysical surveys (SASW analysis).

The potential of Ecotourism in Brazil

Directory of Open Access Journals (Sweden)

Paula Simas de Andrade

2013-01-01

Full Text Available Brazil has a variety of biomes with great potential for ecotourism. They include plateaus, waterfalls, beaches, sand dunes, native forests, mountains and other attractions in regions that are home to poor populations struggling to make their living on smallholder agriculture and that frequently do not have their land rights guaranteed. Implementing ecotourism in these regions can mean environmental preservation and a more sustainable livelihood for the local population. The government has a fundamental role to leverage this activity, providing the means to stimulate sustainable forms of agriculture and infrastructure construction parallel to ecotourism. It is also important to train community members to ensure environmental preservation and well serve the visitors, in addition to implementing measures such as waste recycling and efficient water use.

The right environment for the immunoassay

Emon, J.M. Van; Gerlach, C.L.

1995-01-01

For the US Environmental Protection Agency (EPA), the first in-house research effort began in 1987, when results of an early immunoassay field study verified the technology's potential for environmental applications. Looking at the fundamental features of immunochemical reactions from the clinical laboratories, analytical chemists realized the potential value of these methods for hazardous waste site characterization and pesticide monitoring. Immunoassays rely on the interaction between an antibody and a target analyte. For environmental purposes, enzyme immunoassays are generally used. After the target analyte binds to the antibody, an enzymatic reaction yields a colorimetric change. This change, read visually or by a spectrophotometer, indicates the concentration of the target analyte. Promising results with assays for compounds (such as paraquat and pentachlorophenol) and compound groups (such as total petroleum hydrocarbons and polychlorinated biphenyls) spurred interest among various entrepreneurs. The first target market for immunoassays was environmental engineers and field crews who needed quick answers on-site to determine the direction of further remediation efforts

Lessons from spatial and environmental assessment of energy potentials for Anaerobic Digestion production systems applied to the Netherlands

Highlights: • There is a substantial gap between bio-energy potential and net energy gain. • For reaching production goals the green gas utilization pathway is preferable. • Environmental sustainability favors the waste management pathway. • Renewable energy production goals and environmental sustainability do not always align. • There is a gap between top–down regulation and actual emission reduction and sustainability. - Abstract: Anaerobic digestion (AD) can play an important role in achieving the renewable energy goals set within the European Union. Within this article the focus is placed on reaching the Dutch local renewable production goal set for the year 2020 with locally available biomass waste flows, avoiding intensive farming and long transport distances of biomass and energy carriers. The bio-energy yields, efficiency and environmental sustainability are analyzed for five municipalities in the northern part of the Netherlands, using three utilization pathways: green gas production, combined heat and power, and waste management. Literature has indicated that there is sufficient bio-energy potential in local waste streams to reach the aforementioned goal. However, the average useful energy finally produced by the AD production pathway is significantly lower, often due to poor quality biomass and difficult harvesting conditions. Furthermore, of the potential bio-energy input in the three utilization pathways considered in this article, on average: 73% can be extracted as green gas; 57% as heat and power; and 44% as green gas in the waste management pathway. This demonstrates that the Dutch renewable production goal cannot be reached. The green gas utilization pathway is preferable for reaching production goals as it retains the highest amount of energy from the feedstock. However, environmental sustainability favors the waste management pathway as it has a higher overall efficiency, and lower emissions and environmental impacts. The main

There is growing evidence that a large number of very low birth weight infants are exhibiting neurobehavioral problems in the absence of cerebral palsy at follow-up that has extended into school age and adolescence. Many clinical factors (ie, chronic lung disease, recurrent apnea and bradycardia, transient hypothyroxemia of prematurity, hyperbilirubinemia, nutritional deficiencies, glucocorticoid exposure), as well as stressful environmental conditions, including infant-provider interaction, constant noise, and bright light, may act in combination to impact on the developing brain, even in the absence of overt hemorrhage and/or ischemia. Any potential intervention strategy designed to prevent cognitive and behavioral problems has to account for the numerous biological and clinical conditions and/or interventions, as well as postdischarge social and environmental influences.

The purpose of this paper was to summarize current findings on community gardens relevant to three specific areas of interest as follows: (1) health benefits, (2) garden interventions in developing versus developed countries, and (3) the concerns and risks of community gardening. Community gardens are a reemerging phenomenon in many low- and high-income urban neighborhoods to address the common risk factors of modern lifestyle. Community gardens are not limited to developed countries. They also exist in developing low-income countries but usually serve a different purpose of food security. Despite their benefits, community gardens can become a source of environmental toxicants from the soil of mostly empty lands that might have been contaminated by toxicants in the past. Therefore, caution should be taken about gardening practices and the types of foods to be grown on such soil if there was evidence of contamination. We present community gardens as additional solutions to the epidemic of chronic diseases in low-income urban communities and how it can have a positive physical, mental and social impact among participants. On balance, the benefits of engaging in community gardens are likely to outweigh the potential risk that can be remedied. Quantitative population studies are needed to provide evidence of the benefits and health impacts versus potential harms from community gardens.

The hydropower plants are responsible for much of the energy generated in the country, there is also a large hydro potential in Brazilian rivers. This form of power generation is considered renewable and fits into the concept of sustainable development, however, social and environmental impacts from the implementation of hydropower projects are known and widely discussed, especially when it comes to large plants. In this context, study the environmental analysis of potential hydropower was incorporated at various stages of the studies implementation, in order to, identify environmental factors and that will restrict or impede construction, to obtain the best option for the environment, evaluate the role and of social and environmental impacts, contribute to improving the design and functionality of the enterprises in order to reduce overall costs, minimize conflicts and assist in preserving the environment. To fulfill these functions to a satisfactory and reliable level, it the study has increasingly used the techniques, tools and applications of Geographic Information Systems in the process of environmental assessment, since they provide procurement, integration, visualization and data analysis of natural resources, its uses and protection, offering greater security and speed in decision making. This paper presents some applications of GIS in environmental assessment processes, developed mainly in the steps of estimating hydropower potential, hydropower inventory, basic design and environmental licensing.

Hartz, Lacey E; Bradshaw, Wanda; Brandon, Debra H

2015-10-01

To identify how the neonatal intensive care unit (NICU) environment potentially influences the microbiome high-risk term and preterm infants. Electronic databases utilized to identify studies published in English included PubMed, Google Scholar, Cumulative Index for Nursing and Allied Health Literature, and BioMedSearcher. Date of publication did not limit inclusion in the review. Two hundred fifty articles were assessed for relevance to the research question through title and abstract review. Further screening resulted in full review of 60 articles. An in-depth review of all 60 articles resulted in 39 articles that met inclusion criteria. Twenty-eight articles were eliminated on the basis of the type of study and subject of interest. Studies were reviewed for information related to environmental factors that influence microbial colonization of the neonatal microbiome. Environment was later defined as the physical environment of the NICU and nursery caregiving activities. Studies were characterized into factors that impacted the infant's microbiome—parental skin, feeding type, environmental surfaces and caregiving equipment, health care provider skin, and antibiotic use. Literature revealed that various aspects of living within the NICU environment do influence the microbiome of infants. Caregivers can implement strategies to prevent environment-associated nosocomial infection in the NICU such as implementing infection control measures, encouraging use of breast milk, and decreasing the empirical use of antibiotics.

Ashes produced by thermal treatments of sewage sludge exhibit common properties with cement. For example, major elements present in SSA are the same of major elements of cement. Hydraulic properties of SSA are quite the same of cement ones. They may therefore be used to substitute part of cement in concrete or other cementitious materials, provided that technical prescriptions are satisfied and that environmental risks are not significantly increased. The objective of the present study was to determine the appropriate substitution ratios to satisfy both technical and environmental criteria. In a first step, the elemental composition and particle size distribution of the ashes were measured. Then the ashes were used along with Portland cement and sand at different ratios of substitution to produce mortar and concrete which were cured for up to 90 days into parallelepipedic or cylindrical monoliths. The mechanical properties of the monoliths were measured using standard procedures for flexural and compressive strengths, and compared to blanks containing no ashes. The environmental criteria were assessed using leaching tests conducted according to standard protocols both on the ashes and the monoliths, and compared to the blanks. Results showed that the characteristics of the ashes ranged between those of cement and sand because of their larger particle size and higher content in SiO2 as compared to cement. The monoliths made with the highest substitution ratios exhibited a significant decrease in flexural and compressive strengths. However, when the ashes were used in partial substitution of cement at appropriate ratios, the concrete monoliths exhibited similar compressive strengths as the blank samples. The most appropriate ratios were found to be 10% substitution of cement and 2% substitution of sand. The leaching tests conducted on the ashes in their powdery form revealed that amongst the potential contaminants analyzed only Mo and Se were leached at

Traditional Chinese solid-state fermented cereal starters contain highly complex microbial communities and enzymes. Very little is known, however, about the microbial dynamics related to environmental conditions, and cellulolytic communities have never been proposed to exist during cereal starter fermentation. In this study, we performed Illumina MiSeq sequencing combined with PCR-denaturing gradient gel electrophoresis to investigate microbiota, coupled with clone library construction to trace cellulolytic communities in both fermentation stages. A succession of microbial assemblages was observed during the fermentation of starters. Lactobacillales and Saccharomycetales dominated the initial stages, with a continuous decline in relative abundance. However, thermotolerant and drought-resistant Bacillales, Eurotiales, and Mucorales were considerably accelerated during the heating stages, and these organisms dominated until the end of fermentation. Enterobacteriales were consistently ubiquitous throughout the process. For the cellulolytic communities, only the genera Sanguibacter, Beutenbergia, Agrobacterium, and Erwinia dominated the initial fermentation stages. In contrast, stages at high incubation temperature induced the appearance and dominance of Bacillus, Aspergillus, and Mucor. The enzymatic dynamics of amylase and glucoamylase also showed a similar trend, with the activities clearly increased in the first 7 days and subsequently decreased until the end of fermentation. Furthermore, β-glucosidase activity continuously and significantly increased during the fermentation process. Evidently, cellulolytic potential can adapt to environmental conditions by changes in the community structure during the fermentation of starters. Copyright © 2015, American Society for Microbiology.

Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: A critical review.

Science.gov (United States)

Pathak, Ashish; Morrison, Liam; Healy, Mark Gerard

2017-04-01

Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its wider commercial applicability. Recent advancements in bio-hydrometallurgy have suggested that these critical issues can be successfully alleviated through the addition of a catalyst. The catalyzing properties of a variety of metals ions (Ag + , Hg ++ , Bi +++ , Cu ++ , Co ++ etc.) during bioleaching have been successfully demonstrated. In this article, the role and mechanisms of these metal species in catalyzing bioleaching from different minerals (chalcopyrite, complex sulfides, etc.) and waste materials (spent batteries) are reviewed, techno-economic and environmental challenges associated with the use of metals ions as catalysts are identified, and future prospectives are discussed. Based on the analysis, it is suggested that metal ion-catalyzed bioleaching will play a key role in the development of future industrial bio-hydrometallurgical processes.

Full Text Available The current article has the objective of discussing the limitations imposed on property rights. Using the qualitative research methodology and inductive method, the construction of the text comes from the study of the limiting factors of the use, enjoyment and fruition of the premises, using the contents of the Brazilian Federal Constitution and some of the reflections promoted by Antonio Bartolini, in the lecture Le situazioni giuridiche soggettive nel diritto europeo, as the main theoretical foundation. This research is justified because of the current planet pollution and the scarcity of several natural resources. It attempts to analyze the principle of social function as a restrictive factor, added to the natural and legal - internal and external - limits; modeled on the example of the condominium, the urban plan, the division of urban land and the expropriation, giving particular emphasis to environmental restrictions. As a result, we seek to certify the feasibility of absolute and arbitrary use of the property for a society that moves towards sustainability.

Report: Potential environmental impact of exempt site materials - a case study of bituminous road planings and waste soils.

The use of waste materials for ecological benefit, agricultural improvement or as part of construction works are often exempt from waste management control in order to maximize the reuse of material that would otherwise be disposed of to landfill. It is important, however, to determine whether there is potential for such waste to cause environmental harm in the context of the basis for granting exemptions under the relevant framework objective to ensure that waste is recovered or disposed of without risk to water, air, soil, plants or animals. The potential for environmental harm was investigated by leaching studies on two wastes commonly found at exempt sites: bituminous road planings and waste soils. For bituminous road planings, the organic components of the waste were identified by their solubility in organic solvents but these components would have low environmental impact in terms of bioavailability. Leaching studies of the heavy metals copper, lead and zinc, into the environment, under specific conditions and particularly those modelling acid rain and landfill leachate conditions showed that, except for copper, the amounts leached fell within Waste Acceptance Criteria compliance limits for defining waste as inert waste. The fact that the amount of copper leached was greater than the Waste Acceptance Criteria level suggests that either additional testing of wastes regarded as exempt should be carried out to ensure that they are in analytical compliance or that legislation should allow for the potential benefits of reuse to supersede deviations from analytical compliance.

Public Benefit Fund programs are one approach to provide energy assistance to low-income households placed at risk in a competitive electric industry. The purpose of this paper is to assess the potential economic and environmental impact of a proposed Public Benefit Fund for the state of Louisiana. The 'best available' model to estimate the relationship between the cost of Public Benefit Fund programs and the benefits delivered by its implementation would be based on an evaluation of existent energy conservation and weatherization programs in the state, but unfortunately, such an evaluation has not been previously performed and so the 'next best' analytic model was employed. The impact of a Public Benefit Fund on energy savings and environmental consequences is assessed through a simulation model and input-output analysis. The model developed is based on publicly available data and infer results under a reasonable assumption set. The model structure and system assumptions of the Public Benefit Fund program are described, realistic policy alternatives are examined--including cost-ceiling, variable funding, and target group strategies--and the limitations of the analysis are outlined

Potential bud bank responses to apical meristem damage and environmental variables: matching or complementing axillary meristems?

Science.gov (United States)

Klimešová, Jitka; Malíková, Lenka; Rosenthal, Jonathan; Šmilauer, Petr

2014-01-01

Soil nutrients, dormant axillary meristem availability, and competition can influence plant tolerance to damage. However, the role of potential bud banks (adventitious meristems initiated only after injury) is not known. Examining Central European field populations of 22 species of short-lived monocarpic herbs exposed to various sources of damage, we hypothesized that: (1) with increasing injury severity, the number of axillary branches would decrease, due to axillary meristem limitation, whereas the number of adventitious shoots (typically induced by severe injury) would increase; (2) favorable environmental conditions would allow intact plants to branch more, resulting in stronger axillary meristem limitation than in unfavorable conditions; and (3) consequently, adventitious sprouting would be better enabled in favorable than unfavorable conditions. We found strong support for the first hypothesis, only limited support for the second, and none for the third. Our results imply that whereas soil nutrients and competition marginally influence plant tolerance to damage, potential bud banks enable plants to overcome meristem limitation from severe damage, and therefore better tolerate it. All the significant effects were found in intraspecific comparisons, whereas interspecific differences were not found. Monocarpic plants with potential bud banks therefore represent a distinct strategy occupying a narrow environmental niche. The disturbance regime typical for this niche remains to be examined, as do the costs associated with the banks of adventitious and axillary reserve meristems.

Full Text Available Insects are widely used as biological indicators of environmental quality in environmental monitoring studies, because they have certain aspects that help in the identification of environmental stress. The genus Dichotomius, from the family Scarabaeidae, has a wide occurrence in the Brazilian territory, being found in many Brazilian biomes, including in the Caatinga. The species Dichotomius nisus and Dichotomius aff. Laevicollis were recorded in the Catimbau National Park (PE, study area of this work, in environments of different conservation states. Through secondary data, the characteristics of these two species were analyzed considering certain criteria of ideal bioindicator. Both species demonstrated potential as a tool for indicating environmental quality, despite presenting different responses to a disturbance.

Freddo, Alessia; Cai Chao; Reid, Brian J.

2012-01-01

Nine dissimilar biochars, produced from varying feedstock at different pyrolysis temperatures, are appraised with respect to concentrations of potentially toxic elements, specifically, metals, metalloids and polycyclic aromatic hydrocarbons (PAHs). Concentrations of the metals and metalloids varied with the following ranges (mg kg −1 ): 0.02–0.94, Cd; 0.12–6.48, Cr; 0.04–13.2, Cu; 0.1–1.37, Ni; 0.06–3.87, Pb; 0.94–207, Zn and 0.03–0.27, As. Σ 16 PAH concentrations (16 Environmental Protection Agency (EPA) PAHs) range between 0.08 mg kg −1 to 8.7 mg kg −1 . Subsequent comparison with background soil concentrations, concentration applied to the regulation of composted materials (Publicly Available Specification (PAS 100)) and European Union (EU) regulations relating to the application of sewage sludge to agricultural land suggest low risk associated with the concentrations of PTEs observed in biochar. Collectively, results suggest that environmental impacts attributable to metals, metalloids and PAHs associated with biochar following its application to soil are likely to be minimal. - Highlights: ► Concentrations of PTEs varied with feedstock and temperature of production. ► Of the PTEs Zn (0.94–207 mg kg −1 ) was of most priority. ► PTE levels did not infringe guidance values for compost or sewage sludge. ► Biochar ( −1 ) is unlikely to make any real difference to PTE concentrations in soil. - Environmental impacts attributable to metals, metalloids and PAHs associated with biochar following its application to soil are likely to be minimal.

EDITORIAL: Environmental justice: a critical issue for all environmental scientists everywhere

Science.gov (United States)

Stephens, Carolyn

2007-10-01

It is now commonly understood that much of the worldwide burden of environmental ill health falls disproportionately on poorer peoples [1,2]. There is also substantial evidence that much environmental damage internationally is the result of the actions of richer nations or richer groups within nations—with impacts on poorer nations and poorer groups within nations [1,3,4]. It is becoming clear also that poorer peoples internationally experience multiple environmental harms, and that these may have a cumulative effect. The world is becoming more urbanized, and cities are becoming the locus for many of the local issues of environmental damage and environmental harm [4,5]. But cities are also responsible for substantial international environmental damage: for example, it is increasingly evident that cities are one of the main generators of climate change, and that the actions of people in cities in the rich world are deeply linked to the well-being of the overall ecosystem and of people worldwide. Environmental justice is a concept that links the environmental health science documenting these harms, to debates around rights, justice and equity. It fundamentally deals with the distribution of environmental goods and harms—and looks at who bears those harms and who is responsible for creating those harms, in both a practical sense but also in terms of policy decisions. It is a radical environmental health movement that has evolved from civil society groups, angered at what they perceive as the `unjust' distribution of environmental resources for health and, conversely the `unjust' distribution of environmental harms. The movement now includes a collaboration of non-governmental organizations with environmental scientists, public health professionals, and lawyers, all working on the issue of the distributions of environmental harms and the rights of everyone to a healthy environment. This special issue is both timely and important. Environmental justice is moving

Honeybees and bee products are potential bioindicators of the presence of contaminants in the environment, enabling monitoring of large areas due to the long distances travelled by bees. This work evaluates the use of bee pollen as a bioindicator of environmental contamination by pesticides. A GC-MS/MS analytical method for multiresidue determination of 26 different pesticides in pollen was developed and validated in accordance with the recommendations of the European Union SANCO guide. Environmental monitoring was conducted using the analysis of 145 pollen samples collected from ten beehives in the experimental apiary of Embrapa in Jaguariúna (São Paulo State, Brazil). Bioallethrin and pendimethalin were identified in four and eighteen samples, respectively, at concentrations below the LOQ of the method (25 ng g(-1)). Passive sampling with polyurethane foam discs was used as a control, and no pesticides were found. The detection of pesticide residues in seven samples (33%) from commercial apiaries in Ribeirão Preto (São Paulo State) confirmed the efficiency of the analytical method and the need for environmental monitoring for the presence of pesticide residues. The results demonstrated the potential of bee pollen as a bioindicator of environmental contamination by pesticides. Copyright © 2016 Elsevier Ltd. All rights reserved.

Potential Fusion Market for Hydrogen Production Under Environmental Constraints

International Nuclear Information System (INIS)

Konishi, Satoshi

2005-01-01

Potential future hydrogen market and possible applications of fusion were analyzed. Hydrogen is expected as a major energy and fuel mediun for the future, and various processes for hydrogen production can be considered as candidates for the use of fusion energy. In order to significantly contribute to reduction of CO 2 emission, fusion must be deployed in developing countries, and must substitute fossil based energy with synthetic fuel such as hydrogen. Hydrogen production processes will have to evaluated and compared from the aspects of energy efficiency and CO 2 emission. Fusion can provide high temperature heat that is suitable for vapor electrolysis, thermo-chemical water decomposition and steam reforming with biomass waste. That is a possible advantage of fusion over renewables and Light water power reactor. Despite of its technical difficulty, fusion is also expected to have less limitation for siting location in the developing countries. Under environmental constraints, fusion has a chance to be a major primary energy source, and production of hydrogen enhances its contribution, while in 'business as usual', fusion will not be selected in the market. Thus if fusion is to be largely used in the future, meeting socio-economic requirements would be important

The potential environmental impacts and the siting of proposed nuclear power plants in China

This paper reviews briefly the methodology of assessing environmental impacts from the nuclear power plants and analyses the potential radiological impacts on the environment from proposed nuclear power plants in China. Preliminary studies show that the environmental impacts of the effluents of routine release from PWRs to the proposed sites are extremely small, even if nuclear power plants are constructed either on the Bohai Sea shore with a narrow mouth or in the densely populated regions of Sunan. Thus, the suitability of sites depends mainly on the acceptability of possible exposure to the residents following postulated accidental release of radioactive materials. The paper also discusses relations between the nuclear plant siting and population distribution around the site and compares the distribution of the proposed sites in China with that of other countries sites in according to China actual situation, it is reasonable to adopt a prudent policy that the first series of nuclear power plants in China should be built in relatively low population areas

Dynamic Action Potential Restitution Contributes to Mechanical Restitution in Right Ventricular Myocytes From Pulmonary Hypertensive Rats.

2018-01-01

We investigated the steepened dynamic action potential duration (APD) restitution of rats with pulmonary artery hypertension (PAH) and right ventricular (RV) failure and tested whether the observed APD restitution properties were responsible for negative mechanical restitution in these myocytes. PAH and RV failure were provoked in male Wistar rats by a single injection of monocrotaline (MCT) and compared with saline-injected animals (CON). Action potentials were recorded from isolated RV myocytes at stimulation frequencies between 1 and 9 Hz. Action potential waveforms recorded at 1 Hz were used as voltage clamp profiles (action potential clamp) at stimulation frequencies between 1 and 7 Hz to evoke rate-dependent currents. Voltage clamp profiles mimicking typical CON and MCT APD restitution were applied and cell shortening simultaneously monitored. Compared with CON myocytes, MCT myocytes were hypertrophied; had less polarized diastolic membrane potentials; had action potentials that were triggered by decreased positive current density and shortened by decreased negative current density; APD was longer and APD restitution steeper. APD90 restitution was unchanged by exposure to the late Na + -channel blocker (5 μM) ranolazine or the intracellular Ca 2+ buffer BAPTA. Under AP clamp, stimulation frequency-dependent inward currents were smaller in MCT myocytes and were abolished by BAPTA. In MCT myocytes, increasing stimulation frequency decreased contraction amplitude when depolarization duration was shortened, to mimic APD restitution, but not when depolarization duration was maintained. We present new evidence that the membrane potential of PAH myocytes is less stable than normal myocytes, being more easily perturbed by external currents. These observations can explain increased susceptibility to arrhythmias. We also present novel evidence that negative APD restitution is at least in part responsible for the negative mechanical restitution in PAH myocytes. Thus

Atmospheric chemistry of short-chain haloolefins: photochemical ozone creation potentials (POCPs), global warming potentials (GWPs), and ozone depletion potentials (ODPs).

Wallington, T J; Sulbaek Andersen, M P; Nielsen, O J

2015-06-01

Short-chain haloolefins are being introduced as replacements for saturated halocarbons. The unifying chemical feature of haloolefins is the presence of a CC double bond which causes the atmospheric lifetimes to be significantly shorter than for the analogous saturated compounds. We discuss the atmospheric lifetimes, photochemical ozone creation potentials (POCPs), global warming potentials (GWPs), and ozone depletion potentials (ODPs) of haloolefins. The commercially relevant short-chain haloolefins CF3CFCH2 (1234yf), trans-CF3CHCHF (1234ze(Z)), CF3CFCF2 (1216), cis-CF3CHCHCl (1233zd(Z)), and trans-CF3CHCHCl (1233zd(E)) have short atmospheric lifetimes (days to weeks), negligible POCPs, negligible GWPs, and ODPs which do not differ materially from zero. In the concentrations expected in the environment their atmospheric degradation products will have a negligible impact on ecosystems. CF3CFCH2 (1234yf), trans-CF3CHCHF (1234ze(Z)), CF3CFCF2 (1216), cis-CF3CHCHCl (1233zd(Z)), and trans-CF3CHCHCl (1233zd(E)) are environmentally acceptable. Copyright © 2015 Elsevier Ltd.

Research highlights: → Urban symbiosis creates compatibility of industrial development and waste management. → Mechanical technology leads to more CO 2 emission reduction. → Energy recovery technology leads to more fossil fuel saving. → Clean energy makes recycling technologies cleaner. → Demand management is crucial for realizing potential environmental gains of recycling. - Abstract: With the increasing attention on developing a low-carbon economy, it is necessary to seek appropriate ways on reducing greenhouse gas (GHG) emissions through innovative municipal solid waste management (MSWM), such as urban symbiosis. However, quantitative assessments on the environmental benefits of urban symbiosis, especially in developing countries, are limited because only a limited number of planned synergistic activities have been successful and it is difficult to acquire detailed inventory data from private companies. This paper modifies and applies a two-step simulation system and used it to assess the potential environmental benefits, including the reduction of GHG emissions and saving of fossil fuels, by employing various Japanese plastics recycling/energy-recovery technologies in Shenyang, China. The results showed that among various recycling/energy-recovery technologies, the mechanical waste plastics recycling technology, which produces concrete formwork boards (NF boards), has the greatest potential in terms of reducing GHG emissions (1.66 kg CO 2 e/kg plastics), whereas the technology for the production of refuse plastic fuel (RPF) has the greatest potential on saving fossil fuel consumption (0.77 kgce/kg-plastics). Additional benefits can be gained by applying combined technologies that cascade the utilization of waste plastics. Moreover, the development of clean energy in conjunction with the promotion of new waste plastics recycling programs could contribute to additional reductions in GHG emissions and fossil fuel consumption.

2016-01-01

Full Text Available The environmental impacts of the production system of emblematic French product under official quality marks was investigated using the Life Cycle Assessment (LCA methodology. The study looks at the PDO Beaujolais and Burgundy sector from a broad perspective, i.e. encompassing all steps linked with the products themselves but also complementary activities that belong to this wine sector. To build the Life Cycle Inventory (LCI, a methodology deriving from both product and organizational LCA was developed and applied. The LCI was built using a bottom-up approach. Inventories were first built for a sample of 17 representative companies. Then, these inventories were scaled-up to complete the global LCI at the agrifood sector level. Potential environmental impacts were assessed for 8 indicators. The LCA results show potential environmental impacts for each life cycle step: grape production, wine making and aging, packaging, distribution and activity of stakeholders belonging to the “close environment”. It provided two main outcomes: (i a methodology for the construction of an LCI adapted to the perimeter of an agrifood sector and composed by high quality data; and (ii the identification of potential environmental impacts of the studied agrifood sector, providing assistance for the definition of their strategic orientations for the future.

Prolonged environmental noise exposure can induce pathogenic effects on various physical and psychosocial responses. The first aim of this study was to investigate whether long-term occupational noise exposure could affect neurophysiological, neuropsychological and emotional statuses, with particular respect to attention and working memory. The second aim was to evaluate the effects on the tactile P300 of a specific stressor (background traffic noise) vs a non-specific stress inductor (Stroop test). The comparison between a group of noise-exposed workers (traffic police officers), and a control group (office employees) did not show marked differences in cognitive and emotional profiles. The amplitude of the baseline cognitive potential (P300), recorded during a tactile (electric) discrimination task, resulted higher in noise-exposed workers than in controls, and this enhancement was associated with a lower level of trait anxiety and better mood profiles. Moreover, we found a wider P300 amplitude reduction in traffic police officers than in controls, under noisy conditions due to traffic. The effect of the Stroop test as a stress inductor was negligible and similar in the two groups. The wider amplitude of the non-auditory P300 in traffic police officers in the baseline condition could be a sign of cross-modal cerebral plasticity enhancing attentive processes in the 'stress-free' sensory channel. In addition, noise-exposed workers presented a higher cerebral sensitivity to stress selectively when they were exposed to the habitual environmental stressor.

Poultry litter incineration as a source of energy: reviewing the potential for impacts on environmental health and justice.

Science.gov (United States)

Stingone, Jeanette A; Wing, Steve

2011-01-01

Legislation in North Carolina has mandated obtaining renewable energy from the incineration of poultry waste, resulting in proposals for three poultry-litter-fueled power plants statewide. This article summarizes environmental health and environmental justice issues associated with incineration of poultry waste for the generation of electric power. Emissions from poultry waste incineration include particulate matter, dioxins, arsenic, bioaerosols and other toxins; various components are associated with cardiovascular disease, cancer, respiratory illness, and other diseases. Industrial farm animal production tends to be concentrated in low-income, rural communities, where residents may be more vulnerable to air pollutants due to pre-existing diseases, other exposures and stressors, and poor access to medical services. These communities lack the political clout to prevent citing of polluting facilities or to pressure industry and government to follow and enforce regulations. Policies intended to reduce reliance on fossil fuels have the potential to increase environmental injustices and threats to environmental health.

Potential environmental effects of offshore wind (OSW) energy projects are not well understood, and regulatory agencies are required to make decisions in spite of substantial uncertainty about environmental impacts and their long-term consequences. An understanding of risks associated with interactions between OSW installations and aquatic receptors, including animals, habitats, and ecosystems, can help define key uncertainties and focus regulatory actions and scientific studies on interactions of most concern. To examine the environmental risks associated with OSW developments in the U.S. Pacific Northwest National Laboratory (PNNL) focused on the following four priority research areas in FY 2012: • Environmental Risk Evaluation System (ERES) - Followed project developments on the two OSW projects that PNNL screened in FY 2011 for environmental consequence: Fishermen’s Energy off the coast of Atlantic City, NJ and LEEDCo. near Cleveland, OH in Lake Erie. • Tethys - Developed a smart knowledge base which houses environmental research, data and information pertaining to OSW energy: • Technical Assessment - Produced a new software to create an automated process of identifying and differentiating between flying organism such as birds and bats by using thermal imagery; and • North Atlantic Right Whales - Developed an environmental risk management system to mitigate the impacts on North Atlantic Right Whales (NARW) during installation and piledriving stages of OSW developments. By identifying and addressing the highest priority environmental risks for OSW devices and associated installations the ERES process assists project proponents, regulators, and stakeholders to engage in the most efficient and effective siting and permitting pathways.

The rights of avoidance of third parties and 'protection laws'

International Nuclear Information System (INIS)

Gassner, E.

1981-01-01

After having given an account of the rights of avoidance of third parties and their foundation in the law the author cites an atypical example of a right of avoidance, i.e. the corporation suit in the environmental protection law in the German Laender Bremen and Hesse. The corporations can only denounce the violation of the environmental protection law. These regulations constitute the protection law, namely in favour of the interests of nature protection, i.e. public interests. It is natural that the corporation has only be concerned an independent right of conducting a case. The (altruistic) corporation suit is therefore a complaint suit aiming at administration control and not a means of an individual legal protection. (HSCH) [de

A human-rights-based analysis can be a useful tool for the scientific community and policy makers as they develop codes of conduct, harmonized standards, and national policies for data sharing. The human rights framework provides a shared set of values and norms across borders, defines rights and responsibilities of various actors involved in data sharing, addresses the potential harms as well as the benefits of data sharing, and offers a framework for balancing competing values. The right to enjoy the benefits of scientific progress and its applications offers a particularly helpful lens through which to view data as both a tool of scientific inquiry to which access is vital and as a product of science from which everyone should benefit. © The Author(s) 2015.

The need for developing environmentally superior and sustainable solutions for managing the animal waste at commercial swine farms in eastern North Carolina has been recognized in recent years. Program OPEN (Odor, Pathogens, and Emissions of Nitrogen), funded by the North Carolina State University Animal and Poultry Waste Management Center (APWMC), was initiated and charged with the evaluation of potential environmentally superior technologies (ESTs) that have been developed and implemented at selected swine farms or facilities. The OPEN program has demonstrated the effectiveness of a new paradigm for policy-relevant environmental research related to North Carolina's animal waste management programs. This new paradigm is based on a commitment to improve scientific understanding associated with a wide array of environmental issues (i.e., issues related to the movement of N from animal waste into air, water, and soil media; the transmission of odor and odorants; disease-transmitting vectors; and airborne pathogens). The primary focus of this paper is on emissions of ammonia (NH3) from some potential ESTs that were being evaluated at full-scale swine facilities. During 2-week-long periods in two different seasons (warm and cold), NH3 fluxes from water-holding structures and NH3 emissions from animal houses or barns were measured at six potential EST sites: (1) Barham farm--in-ground ambient temperature anaerobic digester/energy recovery/greenhouse vegetable production system; (2) BOC #93 farm--upflow biofiltration system--EKOKAN; (3) Carrolls farm--aerobic blanket system--ISSUES-ABS; (4) Corbett #1 farm--solids separation/ gasification for energy and ash recovery centralized system--BEST; (5) Corbett #2 farm--solid separation/ reciprocating water technology--ReCip; and (6) Vestal farm--Recycling of Nutrient, Energy and Water System--ISSUES-RENEW. The ESTs were compared with similar measurements made at two conventional lagoon and spray technology (LST) farms (Moore

2018-03-01

Agricultural straw-based pulp making plays a vital role in pulp and paper industry, especially in forest deficient countries such as China. However, the environmental performance of straw-based pulp has scarcely been studied. A life cycle assessment on wheat straw-based pulp making in China was conducted to fill of the gaps in comprehensive environmental assessments of agricultural straw-based pulp making. On average, the global warming potential (GWP), GWP excluding biogenic carbon, acidification potential and eutrophication potential of wheat straw based pulp making are 2299kg CO 2 -eq, 4550kg CO 2 -eq, 16.43kg SO 2 -eq and 2.56kg Phosphate-eq respectively. The dominant factors contributing to environmental impacts are coal consumption, electricity consumption, and chemical (NaOH, ClO 2 ) input. Chemical input decrease and energy recovery increase reduce the total environmental impacts dramatically. Compared with wood-based and recycled pulp making, wheat straw-based pulp making has higher environmental impacts, which are mainly due to higher energy and chemical requirements. However, the environmental impacts of wheat straw-based pulp making are lower than hemp and flax based pulp making from previous studies. It is also noteworthy that biogenic carbon emission is significant in bio industries. If carbon sequestration is taken into account in pulp making industry, wheat straw-based pulp making is a net emitter rather than a net absorber of carbon dioxide. Since wheat straw-based pulp making provides an alternative for agricultural residue management, its evaluation framework should be expanded to further reveal its environmental benefits.

Potential health and environmental impacts attributable to the nuclear and coal fuel cycles: Final report

International Nuclear Information System (INIS)

Gotchy, R.L.

1987-06-01

Estimates of mortality and morbidity are presented based on present-day knowledge of health effects resulting from current component designs and operations of the nuclear and coal fuel cycles, and anticipated emission rates and occupational exposure for the various fuel cycle facilities expected to go into operation during the next decade. The author concluded that, although there are large uncertainties in the estimates of potential health effects, the coal fuel cycle alternative has a greater health impact on man than the uranium fuel fycle. However, the increased risk of health effects for either fuel cycle represents a very small incremental risk to the average individual in the public for the balance of this century. The potential for large impacts exists in both fuel cycles, but the potential impacts associated with a runaway Greenhouse Effect from combustion of fossil fuels, such as coal, cannot yet be reasonably quantified. Some of the potential environmental impacts of the coal fuel cycle cannot currently be realistically estimated, but those that can appear greater than those from the nuclear fuel cycle. 103 refs., 1 fig., 18 tabs

Rights Language in the Sustainable Development Agenda: Has Right to Health Discourse and Norms Shaped Health Goals?

Directory of Open Access Journals (Sweden)

Lisa Forman

2015-12-01

Full Text Available While the right to health is increasingly referenced in Sustainable Development Goal (SDG discussions, its contribution to global health and development remains subject to considerable debate. This hypothesis explores the potential influence of the right to health on the formulation of health goals in 4 major SDG reports. We analyse these reports through a social constructivist lens which views the use of rights rhetoric as an important indicator of the extent to which a norm is being adopted and/or internalized. Our analysis seeks to assess the influence of this language on goals chosen, and to consider accordingly the potential for rights discourse to promote more equitable global health policy in the future.

The Energy Policy Act of 1992, Section 801 (US Congress, 1992) provides for the US Environmental Protection Agency (EPA) to contract the National Academy of Sciences (NAS) to conduct a study and provide findings and recommendations on reasonable standards for the disposal of high-level wastes at the Yucca Mountain site. The NAS study is to provide findings and recommendations which include, among other things, whether a health-based standard based on dose to individual members of the public from releases to the accessible environment will provide a reasonable standard for the protection of the health and safety of the public. The EPA, based upon and consistent with the findings and recommendations of the NAS, is required to promulgate standards for protection of the public from releases from radioactive materials stored or disposed of in a repository at the Yucca Mountain site. This document presents a number of different ''simple'' analyses of undisturbed repository performance that are intended to provide input to those responsible for setting appropriate environmental standards for a potential repository at the Yucca Mountain site in Nevada. Each of the processes included in the analyses has been simplified to capture the primary significance of that process in containing or isolating the waste from the biosphere. In these simplified analyses, the complex waste package interactions were approximated by a simple waste package ''failure'' distribution which is defined by the initiation and rate of waste package ''failures''. Similarly, releases from the waste package and the engineered barrier system are controlled by the very near field environment and the presence and rate of advective and diffusive release processes. Release was approximated by either a simple alteration-controlled release for the high solubility radionuclides and either a diffusive or advective-controlled release for the solubility-limited radionuclides

A series of Galician (NW Spain) wines, such as Rías Baixas and Ribeiro have acquired international renown in the past few years. In this particular study, viticulture, vinification and bottling and packaging in a winery of the Ribeiro appellation were studied from a life cycle assessment perspective, with the main objective of identifying the largest environmental impacts for four different years of production (2007-2010). The selected functional unit was a 750 mL bottle of Ribeiro white wine, packaged for distribution. Inventory data was gathered mainly through direct communication using questionnaires. Results showed considerable annual variability in environmental performance, stressing the importance of including timeline analysis in the wine sector. Therefore, environmental scaling was proposed for the assessed wine based on the individual environmental impacts for each harvest year. Furthermore, the main hot spots identified were compost and pesticide production and emissions, in the agricultural phase and bottle production and electricity consumption, in the subsequent stages of wine production, in most of the selected impact categories. Suggested improvement opportunities included shifts in the compost transportation policy, recovery of natural resources for vineyard infrastructure, the introduction of new packaging formats in the bottling process and the use of pesticides with lower toxicity potential.

Algae have several industrial applications that can lower the cost of biofuel co-production. Among these co-production applications, environmental and wastewater bioremediation are increasingly important. Heavy metal pollution and its implications for public health and the environment have led to increased interest in developing environmental biotechnology approaches. We review the potential for algal biosorption and/or neutralization of the toxic effects of heavy metal ions, primarily focusing on their cellular structure, pretreatment, modification, as well as potential application of genetic engineering in biosorption performance. We evaluate pretreatment, immobilization, and factors affecting biosorption capacity, such as initial metal ion concentration, biomass concentration, initial pH, time, temperature, and interference of multi metal ions and introduce molecular tools to develop engineered algal strains with higher biosorption capacity and selectivity. We conclude that consideration of these parameters can lead to the development of low-cost micro and macroalgae cultivation with high bioremediation potential. Copyright © 2016 Elsevier Ltd.

Palmas, Claudia; Siewert, Almut [Leibniz Univ. of Hannover (Germany). Dept. of Environmental Planning

2013-07-01

In Europe, the integration of decentralized renewable energy production in regional planning processes plays a crucial role. In particular, regions face a major challenge in order to set up renewable decentralized energy systems and incorporate them into the electricity grid. This paper presents a methodological concept and preliminary tests of applications in order to create an optimization model for an improved renewable energy development and planning practice: firstly, the energy potentials of micro renewable resources are estimated, and secondly the outcomes are combined with an estimation of resulting environmental impacts. Including these data into the spatial analysis, different scenarios can be developed in order to support decision making in landscape planning on the basis of environmental and landscape criteria as well as energy issues, including technical aspects and costs. The case study area is the Hannover region. First results show good energy potentials, which will be in a next step evaluated and combined with environmental impacts in order to improve energy efficiency by integrated renewable, decentralized power plants and energy mix.

The potential influence of short-term environmental variability on the composition of testate amoeba communities in Sphagnum peatlands.

Sullivan, Maura E; Booth, Robert K

2011-07-01

Testate amoebae are a group of moisture-sensitive, shell-producing protozoa that have been widely used as indicators of changes in mean water-table depth within oligotrophic peatlands. However, short-term environmental variability (i.e., sub-annual) also probably influences community composition. The objective of this study was to assess the potential influence of short-term environmental variability on the composition of testate amoeba communities in Sphagnum-dominated peatlands. Testate amoebae and environmental conditions, including hourly measurements of relative humidity within the upper centimeter of the peatland surface, were examined throughout the 2008 growing season at 72 microsites within 11 peatlands of Pennsylvania and Wisconsin, USA. Relationships among testate amoeba communities, vegetation, depth to water table, pH, and an index of short-term environmental variability (EVI), were examined using nonmetric multidimensional scaling and correlation analysis. Results suggest that EVI influences testate amoeba communities, with some taxa more abundant under highly variable conditions (e.g., Arcella discoides, Difflugia pulex, and Hyalosphenia subflava) and others more abundant when environmental conditions at the peatland surface were relatively stable (e.g., Archerella flavum and Bullinularia indica). The magnitude of environmental variability experienced at the peatland surface appears to be primarily controlled by vegetation composition and density. In particular, sites with dense Sphagnum cover had lower EVI values than sites with loose-growing Sphagnum or vegetation dominated by vascular plants and/or non-Sphagnum bryophytes. Our results suggest that more environmental information may be inferred from testate amoebae than previously recognized. Knowledge of relationships between testate amoebae and short-term environmental variability should lead to more detailed and refined environmental inferences.

The Implementation of Earth Jurisprudence through Substantive Constitutional Rights of Nature

Directory of Open Access Journals (Sweden)

Nathalie Rühs

2016-02-01

Full Text Available To date, international processes associated with sustainable development have not led to an internationally legally binding framework that adequately addresses the challenges we face. Human influence on the planet has led to the adoption, although not universally accepted, of the term Anthropocene to define our new relationship with nature. This paper aims to look at the role and rule of law in the making of society and, more importantly, the arguments for a shift in the paradigm from an Anthropocentric ontology to a more Earth-centered one. We critique the current approach to sustainable development and environmental protection, review arguments on the Rights of Nature and explore the potential for the concept of Earth Jurisprudence building on current literature. In particular, the paper outlines that a constitutional right of nature is needed to address the challenges that we now face globally. To this end, we also examine in detail the case study of the constitution of Ecuador where the rights of nature have been codified. We outline some of the key issues involved in this proposed approach to new legal frameworks and make recommendations for future research.

2016-12-01

The potential environmental impact of wasted food minimisation versus its utilisation in a circular bioeconomy is investigated based on a case study of Ireland. The amount of wasted food and food residue (WFFR) produced in 2010 was used for business-as-usual, (a) and four management options were assessed, (b) minimisation, (c) composting, (d) anaerobic digestion and (e) incineration. The environmental impacts Global Warming Potential (GWP), Acidification Potential (AP) and Eutrophication Potential (EP) were considered. A carbon return on investment (CRoI) was calculated for the three processing technologies (c-e). The results showed that a minimisation strategy for wasted food would result in the greatest reduction of all three impacts, -4.5 Mt CO 2 -e (GWP), -11.4 kt PO 4 3 -e (EP) and -43.9 kt SO 2 -e (AP) compared to business as usual. For WFFR utilisation in the circular bioeconomy, anaerobic digestion resulted in the lowest environmental impact and best CRoI of -0.84 kg CO 2 -e per Euro. From an economic perspective, for minimisation to be beneficial, 0.15 kg of wasted food would need to be reduced per Euro spent. Copyright © 2016 Elsevier Ltd. All rights reserved.

The detection of a sexually transmitted infection (STI) agent in a urine specimen from a young child is regarded as an indicator of sexual contact. False positives may conceivably arise from the transfer of environmental contaminants in clinic toilet or bathroom facilities into urine specimens. The potential for contamination of urine specimens with environmental STI nucleic acid was tested empirically in the male and female toilets or bathrooms at 10 Northern Territory (Australia) clinics, on 7 separate occasions at each. At each of the 140 experiments, environmental contamination with Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis nucleic acid contamination was determined by swabbing 10 locations, and urine collection was simulated 5 times, using a (1) synthetic urine surrogate and (2) a standardized finger contamination procedure. The most contaminated toilets and bathrooms were in remote Indigenous communities. No contamination was found in the Northern Territory Government Sexual Assault Referral Centre clinics, and intermediate levels of contamination were found in sexual health clinics and in clinics in regional urban centres. The frequency of surrogate urine sample contamination was low but non-zero. For example, 4 of 558 of the urine surrogate specimens from remote clinics were STI positive. This is by far the largest study addressing the potential environmental contamination of urine samples with STI agents. Positive STI tests arising from environmental contamination of urine specimens cannot be ruled out. The results emphasize that urine specimens from young children taken for STI testing should be obtained by trained staff in clean environments, and duplicate specimens should be obtained if possible. © The Author 2013.

2018-01-01

The increasing application of iron-based nanoparticles (NPs), especially high concentrations of zero-valent iron nanoparticles (nZVI), has raised concerns regarding their environmental behavior and potential ecological effects. In the environment, iron-based NPs undergo physical, chemical, and/or biological transformations as influenced by environmental factors such as pH, ions, dissolved oxygen, natural organic matter (NOM), and biotas. This review presents recent research advances on environmental transformations of iron-based NPs, and articulates their relationships with the observed toxicities. The type and extent of physical, chemical, and biological transformations, including aggregation, oxidation, and bio-reduction, depend on the properties of NPs and the receiving environment. Toxicities of iron-based NPs to bacteria, algae, fish, and plants are increasingly observed, which are evaluated with a particular focus on the underlying mechanisms. The toxicity of iron-based NPs is a function of their properties, tolerance of test organisms, and environmental conditions. Oxidative stress induced by reactive oxygen species is considered as the primary toxic mechanism of iron-based NPs. Factors influencing the toxicity of iron-based NPs are addressed and environmental transformations play a significant role, for example, surface oxidation or coating by NOM generally lowers the toxicity of nZVI. Research gaps and future directions are suggested with an aim to boost concerted research efforts on environmental transformations and toxicity of iron-based NPs, e.g., toxicity studies of transformed NPs in field, expansion of toxicity endpoints, and roles of laden contaminants and surface coating. This review will enhance our understanding of potential risks of iron-based NPs and proper uses of environmentally benign NPs. Copyright © 2017 Elsevier Ltd. All rights reserved.

Fundamental rights reflected by the legislation regarding radiation and nuclear power

Despite the visible growth in radiation usage and nuclear power development, the analysis of their relationship with fundamental rights, a subject of public concern regarding issues including the right to health, environmental rights, safety rights, the right to know, the right to development, and the right to life, is currently non-existent. 15-29By examining various fundamental rights in the context of positive laws regarding radiation and nuclear power in an idealistic perspective that guarantees the maximum degree of rights, this paper aims to propose legislative supplements that will lead to improvements in quality of life. In the South Korean Constitution, radiation and nuclear power is a subject incorporating several rights, including at least 12 clauses that are directly related to fundamental rights; these constitutional rights are manifested in the various clauses of the 14 positive laws regarding radiation and nuclear power. The question on the relative importance of each fundamental right as reflected in these positive laws- whether the right to life should be prioritized or considered equal in weight to the right to health, environmental rights, the right to know, and safety rights- requires careful deliberation and is difficult to humanly resolve in the short term. Making policy that expands the usage of radiation and nuclear power while simultaneously preventing their associated risks is an important task for the Republic of Korea, and a proper value judgment is necessary to find a balance in its associated rights

Environmental issues in oil and gas operations in Yukon and in the N.W.T

MacWilliam, A.G.

1999-01-01

Companies planning an expansion into the two territories ought to examine the way each territory deals with potential environmental issues such as spills, releases, contaminated sites and the reclamation of land. Recent legislation has provided each territory with a certain amount of autonomy, which includes the ability to oversee environmental protection. The Yukon, in particular, has considerable freedom in addressing environmental issues relating to oil and gas activities. Both territories are subject to the input and approval of the federal government and First Nations citizens where their respective interests or lands are involved. An overview is included of the regulation of environmental matters north of the 60th parallel. Although the expansion of oil and gas companies into the two territories 'north of 60' offers new opportunities, operators must consider the potential for environmental issues such as spills, releases, site contamination and reclamation of land. In the Yukon where the government has assumed jurisdiction to regulate oil and gas resources, it is implementing a comprehensive regime to deal with environmental issues, at first, in draft form. In contrast, in the N.W.T. the federal government retains considerable control over gas and oil rights and the consequent environmental issues, and, accordingly, it is essential to be aware of federal environmental regulations for the time being

One of the major objectives was to develop programs for environmental assessment and protection that could serve as an example for similar types of development. The monitoring studies were designed to establish baseline conditions (predevelopment) of the physical, biological, and human environment. Potential changes were assessed and adverse environmental impacts minimized. No major environmental impacts resulted from development of the Raft River Geothermal Research Facility. The results of the physical, biological, and human environment monitoring programs are summarized.

Rights Language in the Sustainable Development Agenda: Has Right to Health Discourse and Norms Shaped Health Goals?

Forman, Lisa; Ooms, Gorik; Brolan, Claire E

2015-09-29

While the right to health is increasingly referenced in Sustainable Development Goal (SDG) discussions, its contribution to global health and development remains subject to considerable debate. This hypothesis explores the potential influence of the right to health on the formulation of health goals in 4 major SDG reports. We analyse these reports through a social constructivist lens which views the use of rights rhetoric as an important indicator of the extent to which a norm is being adopted and/or internalized. Our analysis seeks to assess the influence of this language on goals chosen, and to consider accordingly the potential for rights discourse to promote more equitable global health policy in the future. © 2015 by Kerman University of Medical Sciences.

A group of business, government, environmental and academic leaders convened in a dialogue by the Aspen Institute proposed a series of actions to promote the widespread commercialization of both corn and cellulosic ethanol to improve energy security, the environment, and the economy. Co-chaired by Booz Allen Hamilton Vice President and former CIA Director R. James Woolsey and former Congressman Tom Ewing (R. IL), they developed a series of recommendations involving improved crop yields, processing of biomass into ethanol, manufacture of more cars that can burn either ethanol or gasoline, and the provision of ethanol pumps at more filling stations. Their report, "A High Growth Strategy for Ethanol, includes a discussion of the potential of ethanol, the group's recommendations, and a series of discussion papers commissioned for the dialogue.

To address the sustainability challenge, a large variety of footprints, aiming at capturing specific impacts of human activities on natural environment, have emerged. But, how do they fit into our addressing of environmental sustainability? Here, we build on a critical literature review to (1......) provide an overview of existing footprints; (2) define their roles; (3) position them within the broad spectrum of known environmental problems and control variables of the planetary boundaries; and (4) argue for the need of consistent thresholds to benchmark footprint scores against absolute...

Australia's pesticide environmental risk assessment failure: the case of diuron and sugarcane.

Science.gov (United States)

Holmes, Glen

2014-11-15

In November 2012, the Australian Pesticide and Veterinary Medicines Authority (APVMA) concluded a 12 year review of the PSII herbicide diuron. One of the primary concerns raised during the review was the potential impact on aquatic ecosystems, particularly in the catchments draining to the Great Barrier Reef. The environmental risk assessment process used by the APVMA utilised a runoff risk model developed and validated under European farming conditions. However, the farming conditions in the sugarcane regions of the Great Barrier Reef catchments have environmental parameters beyond the currently validated bounds of the model. The use of the model to assess environmental risk in these regions is therefore highly inappropriate, demonstrating the pitfalls of a one size fits all approach. Copyright © 2014 Elsevier Ltd.

A study of the landslide potential along the mountain road using environmental indices

Science.gov (United States)

Lin, C. Y.

2014-12-01

Utilization of slope land in recent years is rapid as a result of the dense population and limit of land resources in Taiwan. Therefore, mountain road plays an essential role for the necessity of human life. However, landslide disaster resulting in road failure occurred frequently in Taiwan on the slope land due to earthquake and typhoon. Previous studies found that the extreme rainfall coupled with the property of fragile geology could cause landslide. Nevertheless, the landslide occurrence might be affected by the drainage of the road side ditches. Taiwan Highway No.21 in Chi-Shan watershed and the forest roads located in Xiao-Lin Village, which failure during the hit of Typhoon Morakot in 2009, were selected for exploring the potential of vulnerable to landslides. Topographic Wetness Index (TWI) and Road Curvature (RC) were extracted along the road to indicate the potential sites which are vulnerable to slope failure. The surface runoff diverted by the road side ditches could spoil the sites with high RC due to the straight movement characteristics of the diverted runoff and cause the downslope collapse. The sites with higher mean value and lower standard deviation of Normalized Difference Vegetation Index (NDVI) derived from the SPOT imagery taken in dry and/or rainy seasons could be implied as the vegetation stands showing highly buffer effects in environmental stress due to having deeper soil layer, and are hardly interfered by the drought. The stands located in such sites once collapsed are often resulting in huge volumes of debris. Drainage Density (DD) index could be applied as the degrees of geologic fragile in the slope land. A road across the sites with higher mean value and lower standard deviation of NDVI and/or higher DD should be paid more attention because of having highly vulnerable to deep seated landslide. This study is focusing on extracting and analyzing the environmental indices such as TWI, RC, NDVI and DD for exploring the slope stability

Full Text Available Discrepancies between the Bill nº4148 / 2008 and Principle 10, which has about the commitment of States to ensure access to environmental information, generate the need for reflection on the actual Brazilian paradigms front of such a commitment, as well as sustainability Informational as a prerequisite to the realization of rights. Thus, the objective is to generally examine the relevant provisions to Principle 10, the prospects of the Declaration on Principle 10 in Latin America and the Caribbean and investigate the fundamentals of Bill No. 4148/2008, from the perspective of informational sustainability . After it is intended specifically delineate the contrasts between international goals and the said bill. It seeks to answer the question: The reasons which led the Law No. Project. 4148/2008 to the National Congress and its approval in the Chamber of Deputies, can be considered as opposed to the international commitments made by Brazil, with regard to sustainable environmental information, consolidating in a legal setback? The methodology has as basis of theory and approach to systemic-complex perspective. Procedures are bibliographical and documentary research. The technique is building fichamentos and summaries. Conclusively, one sees that Brazil has adopted contradictory paradigms for the right to environmental information, which need to be better delineated, otherwise these setbacks consubstanciarem in legal setback.

Provincial carbon intensity abatement potential estimation in China: A PSO–GA-optimized multi-factor environmental learning curve method

International Nuclear Information System (INIS)

Yu, Shiwei; Zhang, Junjie; Zheng, Shuhong; Sun, Han

2015-01-01

This study aims to estimate carbon intensity abatement potential in China at the regional level by proposing a particle swarm optimization–genetic algorithm (PSO–GA) multivariate environmental learning curve estimation method. The model uses two independent variables, namely, per capita gross domestic product (GDP) and the proportion of the tertiary industry in GDP, to construct carbon intensity learning curves (CILCs), i.e., CO 2 emissions per unit of GDP, of 30 provinces in China. Instead of the traditional ordinary least squares (OLS) method, a PSO–GA intelligent optimization algorithm is used to optimize the coefficients of a learning curve. The carbon intensity abatement potentials of the 30 Chinese provinces are estimated via PSO–GA under the business-as-usual scenario. The estimation reveals the following results. (1) For most provinces, the abatement potentials from improving a unit of the proportion of the tertiary industry in GDP are higher than the potentials from raising a unit of per capita GDP. (2) The average potential of the 30 provinces in 2020 will be 37.6% based on the emission's level of 2005. The potentials of Jiangsu, Tianjin, Shandong, Beijing, and Heilongjiang are over 60%. Ningxia is the only province without intensity abatement potential. (3) The total carbon intensity in China weighted by the GDP shares of the 30 provinces will decline by 39.4% in 2020 compared with that in 2005. This intensity cannot achieve the 40%–45% carbon intensity reduction target set by the Chinese government. Additional mitigation policies should be developed to uncover the potentials of Ningxia and Inner Mongolia. In addition, the simulation accuracy of the CILCs optimized by PSO–GA is higher than that of the CILCs optimized by the traditional OLS method. - Highlights: • A PSO–GA-optimized multi-factor environmental learning curve method is proposed. • The carbon intensity abatement potentials of the 30 Chinese provinces are estimated by

Basic environmental questions concerning lawsuits of neighboring power plant dwellers

1982-01-01

In conjunction with the constellation of lawsuits within the administrative court system, and based on modern environmental protection laws, emission control laws, and foremost, the atomic energy laws, we are confronted with a variety of constitutional and administrative problems. However, the fundamental questions of individual rights within the potentially incriminating environmental utilization or exploitation by individuals could be relatively clearly answered by observing the basic principles of our legal order. It is to be expected that the administrative courts will arrive at acceptable decisions reflecting the full protection of the law and the basic constitutional principles, and that these - once made - may serve as orientation in superior court actions.

Development and use of innovative approaches to waste management and environmental restoration: Potential liability and its implications

Energy Technology Data Exchange (ETDEWEB)

Owens, W.L.

1990-12-01

The US Department of Energy (DOE) has established as its goal to have all of its facilities cleaned up and in compliance with all applicable environmental laws by the year 2019. As part of its plan to achieve that goal, DOE created, in November 1989, an Office of Environmental Restoration and Waste Management (EM) and, within EM, an Office of Technology Development (OTD). Since the achievement of DOE's long-term objective in the area of waste management and environmental restoration is not possible utilizing only existing technology, the importance of OTD's mission is clear. A question has been raised regarding the nature of the potential liability associated with development, testing, and use of new technologies for waste management and environmental restoration; and the impact it may have on the ability or willingness of other parties to participate in DOE's technology development program. This report is intended to provide at least a preliminary answer to the question. Given the range of activities involved in the technology development process, there are many circumstances that could result in liability. Therefore, the discussion here is somewhat general. It may, however, provide a base for more detailed analysis, at a later time, of liability issues raised by specific circumstances.

Promoting obesity prevention together with environmental sustainability.

Skouteris, Helen; Cox, Rachael; Huang, Terry; Rutherford, Leonie; Edwards, Susan; Cutter-Mackenzie, Amy

2014-09-01

There is mounting evidence that current food production, transport, land use and urban design negatively impact both climate change and obesity outcomes. Recommendations to prevent climate change provide an opportunity to improve environmental outcomes and alter our food and physical activity environments in favour of a 'healthier' energy balance. Hence, setting goals to achieve a more sustainable society offers a unique opportunity to reduce levels of obesity. In the case of children, this approach is supported with evidence that even from a young age they show emerging understandings of complex environmental issues and are capable of both internalizing positive environmental values and influencing their own environmental outcomes. Given young children's high levels of environmental awareness, it is easy to see how environmental sustainability messages may help educate and motivate children to make 'healthier' choices. The purpose of this paper is to highlight a new approach to tackling childhood obesity by tapping into existing social movements, such as environmental sustainability, in order to increase children's motivation for healthy eating and physical activity behaviours and thus foster more wholesome communities. We contend that a social marketing framework may be a particularly useful tool to foster behaviour change beneficial to both personal and environmental health by increasing perceived benefits and reducing perceived costs of behaviour change. Consequently, we propose a new framework which highlights suggested pathways for helping children initiate and sustain 'healthier' behaviours in order to inform future research and potentially childhood obesity intervention strategies. © The Author (2013).

Automated negotiation in environmental resource management: Review and assessment.

Science.gov (United States)

Eshragh, Faezeh; Pooyandeh, Majeed; Marceau, Danielle J

2015-10-01

Negotiation is an integral part of our daily life and plays an important role in resolving conflicts and facilitating human interactions. Automated negotiation, which aims at capturing the human negotiation process using artificial intelligence and machine learning techniques, is well-established in e-commerce, but its application in environmental resource management remains limited. This is due to the inherent uncertainties and complexity of environmental issues, along with the diversity of stakeholders' perspectives when dealing with these issues. The objective of this paper is to describe the main components of automated negotiation, review and compare machine learning techniques in automated negotiation, and provide a guideline for the selection of suitable methods in the particular context of stakeholders' negotiation over environmental resource issues. We advocate that automated negotiation can facilitate the involvement of stakeholders in the exploration of a plurality of solutions in order to reach a mutually satisfying agreement and contribute to informed decisions in environmental management along with the need for further studies to consolidate the potential of this modeling approach.

Potential economic impacts of achieving good environmental status in Black Sea fisheries

Directory of Open Access Journals (Sweden)

Ian C. Goulding

2014-09-01

Full Text Available The Marine Strategy Framework Directive (MSFD mandates that European Union (EU member states achieve Good Environmental Status (GEnS based on an ecosystem-based approach to management. For commercial fisheries, the primary target under the MSFD is one of maximum sustainable yield. Of Black Sea riparian nations, only Romania and Bulgaria are EU member states. Focusing at the supranational level, we review institutions and instruments relevant to management of the Black Sea. The economic values of current fish catches are assessed, and the results of a recent analytical assessment of fish stocks are used to estimate potential future values based on maximum sustainable yields. In the Black Sea region, despite long-standing attempts to improve fisheries management, there remains a lack of effective regional cooperation. Evidence from the scenario analysis suggests that achieving GEnS would not have an undue negative impact on overall fishery sector incomes, and could, with appropriate investments in processing and marketing, deliver increased economic benefits for Black Sea countries. The ongoing policy debate between and within Black Sea coastal states needs to be extended to include recognition of the potential economic and social benefits of effective fisheries management. More work is required to assess returns on investment in interim management measures to deliver GEnS.

Driving forces behind the Chinese public's demand for improved environmental safety.

Over the past decades, the public demand for improved environmental safety keeps increasing in China. This study aims to assess the driving forces behind the increasing public demand for improved environmental safety using a provincial and multi-year (1995, 2000, 2005, 2010, and 2014) panel data and the Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) model. The potential driving forces investigated included population size, income levels, degrees of urbanization, and educational levels. Results show that population size and educational level are positively (Pdemand for improved environmental safety. No significant impact on demand was found due to the degree of urbanization. For the impact due to income level, an inverted U-shaped curve effect with the turning point of ~140,000 CNY GDP per capita is indicated. Since per capita GDP of 2015 in China was approximately 50,000 CNY and far from the turning point, the public demand for improved environmental safety will continue rising in the near future. To meet the increasing public demand for improved environmental safety, proactive and risk prevention based environmental management systems coupled with effective environmental risk communication should be established.

ISO 14000 - the International Environmental Management Standard: Potential impacts on environmental management and auditing in the electric power generation industry

International Nuclear Information System (INIS)

Gauntlett, S.B.; Pierce, J.L.; Pierce, J.L.

1995-01-01

In the framework of environmental management, the concept of voluntary environmental compliance auditing is not in itself a new development. Environmentally conscious firms have for more than a decade, undertaken voluntary audits to help achieve and maintain compliance with environmental regulations and to help identify and correct unregulated or poorly regulated environmental hazard. The firms undertaking the audits were motivated by a desire to mitigate legal and financial risks and/or the desire to be a highly responsible member of the corporate community. Much of the early attention to environmental auditing was in the chemical process industries. Today, there are four current trends affecting environmental auditing: (1) the practice is becoming widespread in all industry groups in both large and small firms; (2) environmental management and audit methodolgies and approaches are being codified in the form of written national and International standards; (3) environmental management programs and in-house audits are increasingly being certified by independent auditors (who are not associated with regulatory agencies); and (4) the certifications are being viewed as marketing and public relations tools. The adoption of ISO 14000 is destined to become the most significant development in international environmental management and auditing. International standards for the development of Environmental Management Systems and the execution of environmental audits do not currently exist. Individual countries, such as England and France, have national standards. One multi-national standard currently exists--the European Economic Community's Eco-Management and Audit Scheme (EMAS). The United States does not have a national environmental management and auditing standard

Cell death is a process of dying within biological cells that are ceasing to function. This process is essential in regulating organism development, tissue homeostasis, and to eliminate cells in the body that are irreparably damaged. In general, dysfunction in normal cellular death is tightly linked to cancer progression. Specifically, the up-regulation of pro-survival factors, including oncogenic factors and antiapoptotic signaling pathways, and the down-regulation of pro-apoptotic factors, including tumor suppressive factors, confers resistance to cell death in tumor cells, which supports the emergence of a fully immortalized cellular phenotype. This review considers the potential relevance of ubiquitous environmental chemical exposures that have been shown to disrupt key pathways and mechanisms associated with this sort of dysfunction. Specifically, bisphenol A, chlorothalonil, dibutyl phthalate, dichlorvos, lindane, linuron, methoxychlor and oxyfluorfen are discussed as prototypical chemical disruptors; as their effects relate to resistance to cell death, as constituents within environmental mixtures and as potential contributors to environmental carcinogenesis. © The Author 2015.

'Underutilised' agricultural land: its definitions, potential use for future biomass production and its environmental implications

Science.gov (United States)

Miyake, Saori; Bargiel, Damian

2017-04-01

A growing bioeconomy and increased demand for biomass products on food, health, fibre, industrial products and energy require land resources for feedstock production. It has resulted in significant environmental and socio-economic challenges on a global scale. As a result, consideration of such effects of land use change (LUC) from biomass production (particularly for biofuel feedstock) has emerged as an important area of policy and research, and several potential solutions have been proposed to minimise such adverse LUC effects. One of these solutions is the use of lands that are not in production or not suitable for food crop production, such as 'marginal', 'degraded', 'abandoned' and 'surplus' agricultural lands for future biomass production. The terms referring to these lands are usually associated with the potential production of 'marginal crops', which can grow in marginal conditions (e.g. poor soil fertility, low rainfall, drought) without much water and agrochemical inputs. In our research, we referred to these lands as 'underutilised' agricultural land and attempted to define them for our case study areas located in Australia and Central and Eastern Europe (CEE). Our goal is to identify lands that can be used for future biomass production and to evaluate their environmental implications, particularly impacts related to biodiversity, water and soil at a landscape scale. The identification of these lands incorporates remote sensing and spatially explicit approaches. Our findings confirmed that there was no universal or single definition of the term 'underutilised' agricultural land as the definitions significantly vary by country and region depending not only on the biophysical environment but also political, institutional and socio-economic conditions. Moreover, our results highlighted that the environmental implications of production of biomass on 'underutilised' agricultural land for biomass production are highly controversial. Thus land use change

As a result of right ventricular outflow tract reconstruction, which is the important and basic step of complex cardiac surgery, the blood flow of right ventricular outflow tract is unobstructed, while pulmonary valve regurgitation and right heart dysfunction could be happened. These problems are often ignored in early days, more and more cases of right heart dysfunction need clinical intervention, which is quite difficult and less effective. How to protect effectively the right ventricular function is the focus. At present main methods to protect the right ventricular function include trying to avoid or reduce length of right ventricular incision, reserving or rebuilding the function of the pulmonary valve, using growth potential material for surgery. The protection of the right ventricular function is a systemic project, it involves many aspects, single measures is difficult to provide complete protection, only the comprehensive use of various protection strategy, can help to improve the long-term prognosis.

When private water rights become a public asset: Stakeholder perspectives on the fairness of environmental water management

Science.gov (United States)

Lukasiewicz, Anna; Dare, Melanie (Lain)

2016-05-01

This paper explores environmental water management as a social process of navigating conflicting interests through a distributive justice lens. Environmental water management can achieve substantial ecological outcomes and address ongoing river degradation caused by past management and climate change; however it also causes specific and substantial burdens and benefits to different groups of stakeholders. Given that in most developed countries the majority of land is under private tenure, environmental watering must have active cooperation of private landholders to achieve its ecological outcomes and thus it must effectively deal with an array of vested interests. Australia's reforms aimed at reallocating water from production to the environment have resulted in significant considerable volumes of environmental water. In the state of New South Wales, this water is managed by the state and national governments with the help of five Environmental Water Advisory Groups made up of a wide representation of interests. In this paper, we explore the perceptions of environmental, government, irrigator and grazing representatives, which demonstrate conflicting principles over how environmental water should be distributed. We detail how government water managers reconcile competing distributive principles of equity (ensuring that no one is disproportionally affected or benefits unduly), need (achieving environmental outcomes) and efficiency (prioritizing operational feasibility) in order to maintain the social acceptability of environmental water.

Environmental agreements, EIA follow-up and aboriginal participation in environmental management: The Canadian experience

International Nuclear Information System (INIS)

O'Faircheallaigh, Ciaran

2007-01-01

During the last decade a number of environmental agreements (EAs) have been negotiated in Canada involving industry, government and Aboriginal peoples. This article draws on the Canadian experience to consider the potential of such negotiated agreements to address two issues widely recognised in academic and policy debates on environmental impact assessment (EIA) and environmental management. The first relates to the need to secure indigenous participation in environmental management of major projects that affect indigenous peoples. The second and broader issue involves the necessity for specific initiatives to ensure effective follow-up of EIA. The Canadian experience indicates that negotiated environmental agreements have considerable potential to address both issues. However, if this potential is to be realized, greater effort must be made to develop structures and processes specifically designed to encourage Aboriginal participation; and EAs must themselves provide the financial and other resource required to support EIA follow-up and Aboriginal participation

Potential CERCLA reauthorization issues relevant to US DOE's Environmental Restoration Program

International Nuclear Information System (INIS)

Siegel, M.R.; McKinney, M.D.; Jaksch, J.A.; Dailey, R.L.

1993-02-01

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is currently scheduled to be reauthorized in 1994. The US Department of Energy (DOE) has a significant stake in CERCLA reauthorization. CERCLA, along with its implementing regulation, the National Contingency Plan (NCP), is the principal legal authority governing DOE's environmental restoration program. The manner in which CERCLA-related issues are identified, evaluated, and dispatched may have a substantial impact on DOE's ability to conduct its environmental restoration program. A number of issues that impact DOE's environmental restoration program could be addressed through CERCLA reauthorization. These issues include the need to (1) address how the National Environmental Policy Act (NEPA) should be integrated into DOE CERCLA actions, (2) facilitate the streamlining of the Superfund process at DOE sites, (3) address the conflicts between the requirements of CERCLA and the Resource Conservation and Recovery Act (RCRA) that are especially relevant to DOE, (4) examine the criteria for waiving applicable or relevant and appropriate requirements (ARARs) at DOE sites, and (5) delineate the appropriate use of institutional controls at DOE sites

The objective of this study is to assess the environmental benefit of using rainwater, greywater, water-efficient appliances and their combinations in low-income houses. The study was conducted surveying twenty households located in southern Brazil, which resulted in water end-uses estimation. Then, embodied energy, potential for potable water savings and sewage reduction when using the different strategies were estimated. The environmental benefit analysis of these strategies was performed using an indicator that includes embodied energy, potable water savings, reduction of sewage and energy consumption in the water utility, and sewage production during the life cycle of the system. The results indicated that the strategy with the greatest environmental benefit is the use of water-efficient appliances, which resulted in substantial water savings and reduction of sewage, causing low environmental impact due to lower embodied energy over the life cycle.

Sabiha, Noor-E; Salim, Ruhul; Rahman, Sanzidur; Rola-Rubzen, Maria Fay

2016-01-15

The present study develops a composite environmental impact index (CEII) to evaluate the extent of environmental degradation in agriculture after successfully validating its flexibility, applicability and relevance as a tool. The CEII tool is then applied to empirically measure the extent of environmental impacts of High Yield Variety (HYV) rice cultivation in three districts of north-western Bangladesh for a single crop year (October, 2012-September, 2013). Results reveal that 27 to 69 per cent of the theoretical maximum level of environmental damage is created due to HYV rice cultivation with significant regional variations in the CEII scores, implying that policy interventions are required in environmentally critical areas in order to sustain agriculture in Bangladesh.

Lead poisoning in China: a health and human rights crisis.

Science.gov (United States)

Cohen, Jane E; Amon, Joseph J

2012-12-15

Acute and chronic lead poisoning is occurring throughout China and is a major cause of childhood morbidity. The Chinese government's emphasis on industrial development and poverty reduction has, over the past three decades, decreased by 500 million the number of people surviving on less than one dollar per day, but has caused significant environmental degradation that threatens public health. Drawing upon in-depth interviews conducted in 2009 and 2010 with families affected by lead poisoning, environmental activists, journalists, government and civil society organization officials in Shaanxi, Henan, Hunan, and Yunnan provinces, as well as a review of scientific and Chinese media, and health and environmental legal and policy analysis, we examine the intersection of civil, political, economic, and social rights related to access to information, screening, treatment, and remediation related to lead poisoning. In-depth interviews in each province uncovered: censorship and intimidation of journalists, environmental activists, and parents seeking information about sources and prevention of lead poisoning; denial of screening for lead poisoning, often based upon arbitrary eligibility criteria; and inadequate and inappropriate treatment being promoted and provided by health facilities. Over the past decade, the Chinese government has prioritized health care and invested billions of dollars towards universal health coverage, and strengthened environmental to address industrial pollution and guarantee access to information on the environment. Yet, despite these reforms, information remains constrained and citizens seeking information and redress are sometimes arrested, in violation of Chinese and international law. Local government officials and national environmental policies continue to prioritize economic development over environmental protection. To effectively address lead poisoning requires an emphasis on prevention, and to combat industrial pollution requires

Advancing the right to health through global organizations: The potential role of a Framework Convention on Global Health.

Science.gov (United States)

Friedman, Eric A; Gostin, Lawrence O; Buse, Kent

2013-06-14

Organizations, partnerships, and alliances form the building blocks of global governance. Global health organizations thus have the potential to play a formative role in determining the extent to which people are able to realize their right to health. This article examines how major global health organizations, such as WHO, the Global Fund to Fight AIDS, TB and Malaria, UNAIDS, and GAVI approach human rights concerns, including equality, accountability, and inclusive participation. We argue that organizational support for the right to health must transition from ad hoc and partial to permanent and comprehensive. Drawing on the literature and our knowledge of global health organizations, we offer good practices that point to ways in which such agencies can advance the right to health, covering nine areas: 1) participation and representation in governance processes; 2) leadership and organizational ethos; 3) internal policies; 4) norm-setting and promotion; 5) organizational leadership through advocacy and communication; 6) monitoring and accountability; 7) capacity building; 8) funding policies; and 9) partnerships and engagement. In each of these areas, we offer elements of a proposed Framework Convention on Global Health (FCGH), which would commit state parties to support these standards through their board membership and other interactions with these agencies. We also explain how the FCGH could incorporate these organizations into its overall financing framework, initiate a new forum where they collaborate with each other, as well as organizations in other regimes, to advance the right to health, and ensure sufficient funding for right to health capacity building. We urge major global health organizations to follow the leadership of the UN Secretary-General and UNAIDS to champion the FCGH. It is only through a rights-based approach, enshrined in a new Convention, that we can expect to achieve health for all in our lifetimes. Copyright © 2013 Friedman, Gostin

Global property rights. The Kyoto protocol and the knowledge revolution

International Nuclear Information System (INIS)

Chichilnisky, G.

2006-01-01

This paper is about the origin of today's global environmental problems, and how to resolve them. At stake are catastrophic risks from global warming and damage to the world's biodiversity that ranks as the planet' sixth great extinction. The origin of today's global environmental problems is a historic difference in property rights regimes between industrial and developing countries, the North and the South. The solutions we suggest involve redefining property rights in the use of the global environment as well as in knowledge. We discuss the Kyoto Protocol's new systems of property rights on the use of the planet's atmosphere, and propose a parallel system of property rights on knowledge. Resources such as forests and oil and other mineral deposits are owned as private property in industrial countries but they are treated as common or government property in developing countries. Ill-defined protected property rights lead to the over-extraction of resources in the South, such as timber and oil. They are exported at low prices to the North that over-consumes them. The international market amplifies the tragedy of the commons, leading to inferior solutions for the world economy as a whole (Chichilnisky 1994). Updating property rights on resources in developing countries would face formidable opposition. The lack of property rights in inputs to production, such as timber and oil, could be compensated by assigning property rights on by-products of outputs. The 1997 Kyoto Protocol provides an example as it limits the countries' rights to emit carbon, a by-product of burning fossil fuels. Our suggestions for trading emissions rights (Chichilnisky 1995, 96) was adopted in the Kyoto Protocol, yet the atmosphere's carbon concentration is a global public good, which makes trading tricky. Trading rights to forests' carbon sequestration services or to genetic blueprints would also be trading global public goods. Markets that trade public goods have been shown to require a

Environmental isotope and geophysical techniques to identify groundwater potential zones in drought prone areas of Amravati District, Maharashtra, India

International Nuclear Information System (INIS)

Jacob, Noble

2017-01-01

The groundwater potential of Anjangaon village in Amaravati district of Maharashtra is generally poor and the water quality is saline in most of the places. Farmers dig open wells (up to 30 m depth) and drill bore wells (100-150 m depth) for domestic and irrigation purposes. Most of the wells failed and farmers are struggling for fresh water in this region. To evaluate the groundwater recharge and to identify the groundwater potential zones an environmental isotope and geophysical study was carried out. Water samples were collected from rain, springs, open wells, bore wells and detention tanks and measured for environmental isotopes such as "1"8O, "2H and "3H. Isotope results indicate that the groundwater is getting modern component of recharge from the rain as well as from the detention tanks. The percentage contributions from the detention tanks were estimated to be about 40 to 90 %. In the southern part of the Anjagaon village, an electrical resistivity survey of the geological formation was carried out and a groundwater potential zone was delineated at 45m depth. The farmers were asked to drill bore wells at the identified depth. The drilled five bore wells yielded perennial source of good quality water

A variety of environmental factors contribute to progressive development of osteoarthritis (OA). Environmental factors that upset circadian rhythms have been linked to various diseases. Our recent work establishes chronic environmental circadian disruption - analogous to rotating shiftwork-associated disruption of circadian rhythms in humans - as a novel risk factor for the development of OA. Evidence suggests shift workers are prone to obesity and also show altered eating habits (i.e., increased preference for high-fat containing food). In the present study, we investigated the impact of chronic circadian rhythm disruption in combination with a high-fat diet (HFD) on progression of OA in a mouse model. Our study demonstrates that when mice with chronically circadian rhythms were fed a HFD, there was a significant proteoglycan (PG) loss and fibrillation in knee joint as well as increased activation of the expression of the catabolic mediators involved in cartilage homeostasis. Our results, for the first time, provide the evidence that environmental disruption of circadian rhythms plus HFD potentiate OA-like pathological changes in the mouse joints. Thus, our findings may open new perspectives on the interactions of chronic circadian rhythms disruption with diet in the development of OA and may have potential clinical implications.

High technology and civil rights

International Nuclear Information System (INIS)

Lerche, P.

1982-01-01

Court decision reflect the widely felt lack of clarity about the present legal situation in the field of high technology. This confusion is also due to the fact that this legal situation is surrounded by civil rights constellations, which have more and more eroded the contours of our legal system in recent years: Today, civil rights are no longer specific, well-definable bulwarks for the citizen, but are more and more frequently interpreted by the supreme courts as sources of procedural requirements with more or less certain often vague consequences. This shifting of the accent in civil rights towards procedural matters is due to an innate logical necessity, however: The same civil right considered in the same situation, e.g., in planning for high technology, may give rise to very different, even contradictory individual claims. Therefore, one of the main modern objectives of civil rights becoming more and more apparent is the need to reconcile conflicting positions, which makes civil rights a driving force in balancing interests in the easiest possible way. Yet, one of the main deficiencies in this rapidly growing procedural approach is the one-sidedness often to be found as a result of isolated, punctual actions. This misses the objective of achieving adequate harmonization. As examples of such one-sided, isolated civil rights approaches, legal opinions are cited on the so-called public participation (possibility to object for those concerned) in the licensing procedures under the German Atomic Energy Act and for protection against environmental impacts. Quity rightly, this participation of the public is interpreted as an advance protection of civil rights. However, its consequences quite often are exaggerated. (orig.) [de

Over the last few years, understanding of the profound implications of anthropogenically driven climate change has grown. In turn, this has fuelled research into options to mitigate likely impacts. Approaches involving the capture of carbon dioxide and its storage in geological formations, or in marine waters, have generated a raft of proposed solutions. The scale of some of these proposals is such that they will exert impacts of global significance in their own right. Proposals fall into two broad categories: (1) storage of liquid CO2 or products of reacted CO2 into intermediate/deep oceanic waters. and (2) storage of liquid CO2 into sub-seabed or terrestrial geological formations. For the most part, while the technical feasibility of these schemata has been widely explored, the same is not true of their ecological implications. In the case of deep/intermediate oceanic waters, poor baseline understanding of the associated ecosystems is a considerable impediment to any reliable predictive assessment of likely impacts of carbon dioxide storage in these systems. Disruption of marine microbiological processes and degradation of benthic ecosystems, including those with high levels of endemicity, have been identified as potentially serious impacts. Similarly, the physiology, ecology and likely responses of micro-organisms present in targeted geological formations require evaluation prior to any consideration of the use of such formations for storage of CO2. In addition, the impacts of any leakage to surface need also to be considered. Accordingly this paper explores current uncertainties and detailed informational needs related to ocean and geological storage of fossil fuel-derived CO2. Particular emphasis is placed upon the ecological impacts of these proposals in relation to existing and emergent understanding of deep water/soil ecosystems and the indeterminacies attached to this understanding.

Fraser Valley System Reinforcement Project: Environmental planning and assessment report

International Nuclear Information System (INIS)

1991-06-01

Transmission facilities in the south central Fraser Valley, British Columbia, need reinforcement in order to meet anticipated growth in power demand. This objective could be met by reinforcing substation facilities (adding 500-kV equipment and connection to transmission line 5L41) at the McLellan Substation in Surrey, at the Clayburn Substation in Matsqui, or at the Atchelitz Substation in Chilliwack. An assessment is provided of the environmental evaluation criteria applied to these potential sites for substation reinforcement and the rationale for selection of the Clayburn site as the environmentally most effective alternative. The Clayburn site is already cleared and managed for a 230-kV substation; environmental, land use, and socioeconomic impacts are considered manageable. The existing right-of-way for the 500-kV loop in to the substation can be utilized. In addition, the results of an environmental assessment and mitigation plan for the Clayburn substation reinforcement are described. The most significant factors that will require possible mitigative measures include fisheries, water quality, floodplain management, visual and recreational aspects, and heritage resources. 16 figs., 5 tabs

Potential of used frying oil in paving material: solution to environmental pollution problem.

2017-05-01

The improper disposal of used frying oil (UFO) presents numerous ecological, environmental and municipal problems. Of great concern is the resultant blockage of municipal drainage systems and water treatment facilities, harm to wildlife when they become coated in it and detriment to aquatic life and ecosystems due to the depletion of the oxygen content in water bodies such as rivers and lakes that have become contaminated. Statistics show that in Trinidad and Tobago, in excess of one million liters of used cooking oil is collected annually from various restaurant chains. This paper investigated the potential of using UFO as a performance enhancing additive for road paving applications utilizing Trinidad Lake Asphalt (TLA) and Trinidad Petroleum Bitumen (TPB) as a mitigation strategy for improper UFO disposal. Modified blends containing various additions of UFO (2-10% wt) were prepared for the TLA and TPB asphaltic binders. Results demonstrated in terms of stiffness, increasing the dosage of UFO in TLA and TPB base binders resulted in a gradual decrease in stiffness (G* value decreased). In terms of elasticity, increasing the dosage of the UFO additive in TLA resulted in a general decrease in the elasticity of the blends indicated by an increase in phase angle or phase lag (δ). Increasing dosages of the UFO additive in TPB resulted in a significant decrease in δ where the most elastic blend was at the 6% UFO level. TLA and UFO-TLA modified blends exhibited significantly lower values of δ and higher values of G* confirming the superiority of the TLA material. Incorporation of the UFO in the blends led to a decrease in the rutting resistance and increase in the fatigue cracking resistance (decrease in G*/sinδ and G*sinδ, respectively). This study highlighted the potential for the reuse of UFO as an asphalt modifier capable of producing customized UFO modified asphaltic blends for special applications and confirms its feasibility as an environmentally attractive

Environmental assessment of the potential effects of aquifer thermal energy storage systems on microorganisms in groundwater

Energy Technology Data Exchange (ETDEWEB)

Hicks, R.J.; Stewart, D.L.

1988-03-01

The primary objective of this study was to evaluate the potential environmental effects (both adverse and beneficials) of aquifer thermal energy storage (ATES) technology pertaining to microbial communities indigenous to subsurface environments (i.e., aquifers) and the propagation, movement, and potential release of pathogenic microorganisms (specifically, Legionella) within ATES systems. Seasonal storage of thermal energy in aquifers shows great promise to reduce peak demand; reduce electric utility load problems; contribute to establishing favorable economics for district heating and cooling systems; and reduce pollution from extraction, refining, and combustion of fossil fuels. However, concerns that the widespread implementation of this technology may have adverse effects on biological systems indigeneous to aquifers, as well as help to propagate and release pathogenic organisms that enter thee environments need to be resolved. 101 refs., 2 tabs.

Full Text Available We investigated whether brain potentials of grammatical aspect processing resemble semantic or morpho-syntactic processing, or whether they instead are characterized by an entirely distinct pattern in the same individuals. We studied aspect from the perspective of agreement between the temporal information in the context (temporal adverbials, e.g., Right now and a morpho-syntactic marker of grammatical aspect (e.g., progressive is swimming. Participants read questions providing a temporal context that was progressive (What is Sophie doing in the pool right now? or habitual (What does Sophie do in the pool every Monday?. Following a lead-in sentence context such as Right now, Sophie…, we measured ERPs time-locked to verb phrases in four different conditions, e.g., (a is swimming (control; (b *is cooking (semantic violation; (c *are swimming (morpho-syntactic violation; or (d?swims (aspect mismatch; …in the pool. The collected ERPs show typical N400 and P600 effects for semantics and morpho-syntax, while aspect processing elicited an Early Negativity (250-350 ms. The aspect-related Negativity was short-lived and had a central scalp distribution with an anterior onset. This differentiates it not only from the semantic N400 effect, but also from the typical (LAN (Left Anterior Negativity, that is frequently reported for various types of agreement processing. Moreover, aspect processing was not accompanied by a clear P600 modulation.We argue that the specific context for each item in this experiment provided a trigger for agreement checking with temporal information encoded on the verb, i.e., morphological aspect marking. The aspect-related Negativity obtained for aspect agreement mismatches reflects a violated expectation concerning verbal inflection (in the example above, the expected verb phrase was Sophie is X-ing rather than Sophie X-s in condition d. The absence of an additional P600 for aspect processing suggests that the mismatch did not

Envisioning a metropolitan foodshed: potential environmental consequences of increasing food-crop production around Chicago

Science.gov (United States)

Bowen, E. E.; Martin, P. A.; Schuble, T. J.

2009-12-01

Nationwide, cities are increasingly developing policies aimed at greater sustainability, particularly focusing on reducing environmental impact. Such policies commonly emphasize more efficiently using energy to decrease the greenhouse gas (GHG) footprint of the city. However, most plans ignore the food system as a factor in regional energy use and GHG emissions. Yet, the food system in the United States accounts for ~20% of per capita greenhouse gas emissions. Local, sustainable food production is cited as one strategy for mitigating GHG emissions of large metropolitan areas. “Sustainable” for regional agriculture is often identified as small-scale, diversified food crop production using best practices management. Localized food production (termed “foodshed”) using sustainable agriculture could mitigate climate change in multiple ways: (1) energy and therefore CO2-intensive portions of the conventional food system might be replaced by local, lower-input food production resulting in carbon offsets; (2) increased regional carbon storage might result from well-managed food crop production vs. commodity crop production; and (3) averted N2O emissions might result from closing nutrient cycles on agricultural lands following changes in management practices. The broader implications for environmental impact of widespread conversion to sustainable food crop agriculture, however, remain largely unknown. We examine the Chicago metropolitan region to quantify the impact of increased local food production on regional energy efficiency and GHG emissions. Geospatial analysis is used to quantify the resource potential for establishing a Chicago metropolitan foodshed. A regional foodshed is defined by minimizing cost through transportation mode (road, rail, or water) and maximizing the production potential of different soil types. Simple biogeochemical modeling is used to predict changes in N2O emissions and nutrient flows following changes in land management practices

Rights for resilience: food sovereignty, power, and resilience in development practice

Directory of Open Access Journals (Sweden)

Marygold Walsh-Dilley

2016-03-01

Full Text Available Even as resilience thinking becomes evermore popular as part of strategic programming among development and humanitarian organizations, uncertainty about how to define, operationalize, measure, and evaluate resilience for development goals prevails. As a result, many organizations and institutions have undertaken individual, collective, and simultaneous efforts toward clarification and definition. This has opened up a unique opportunity for a rethinking of development practices. The emergent consensus about what resilience means within development practice will have important consequences both for development practitioners and the communities in which they work. Incorporating resilience thinking into development practice has the potential to radically transform this arena in favor of social and environmental justice, but it could also flounder as a way to dress old ideas in new clothes or, at worst, to further exploit, disempower, and marginalize the world's most vulnerable populations. We seek to make an intervention into the definitional debates surrounding resilience that supports the former and helps prevent the latter. We argue that resilience thinking as it has been developed in social-ecological systems and allied literatures has a lot in common with the concept of food sovereignty and that paying attention to some of the lessons and claims of food sovereignty movements could contribute toward building a consensus around resilience that supports social and environmental justice. In particular, the food sovereignty movement relies on a strategy that elevates rights. We suggest that a rights-based approach to resilience-oriented development practice could contribute to its application in just and equitable ways.

Host nutrition alters the variance in parasite transmission potential.

Science.gov (United States)

Vale, Pedro F; Choisy, Marc; Little, Tom J

2013-04-23

The environmental conditions experienced by hosts are known to affect their mean parasite transmission potential. How different conditions may affect the variance of transmission potential has received less attention, but is an important question for disease management, especially if specific ecological contexts are more likely to foster a few extremely infectious hosts. Using the obligate-killing bacterium Pasteuria ramosa and its crustacean host Daphnia magna, we analysed how host nutrition affected the variance of individual parasite loads, and, therefore, transmission potential. Under low food, individual parasite loads showed similar mean and variance, following a Poisson distribution. By contrast, among well-nourished hosts, parasite loads were right-skewed and overdispersed, following a negative binomial distribution. Abundant food may, therefore, yield individuals causing potentially more transmission than the population average. Measuring both the mean and variance of individual parasite loads in controlled experimental infections may offer a useful way of revealing risk factors for potential highly infectious hosts.

Hjaila, K; Baccar, R; Sarrà, M; Gasol, C M; Blánquez, P

2013-11-30

The life cycle assessment (LCA) environmental tool was implemented to quantify the potential environmental impacts associated with the activated carbon (AC) production process from olive-waste cakes in Tunisia. On the basis of laboratory investigations for AC preparation, a flowchart was developed and the environmental impacts were determined. The LCA functional unit chosen was the production of 1 kg of AC from by-product olive-waste cakes. The results showed that impregnation using H3PO4 presented the highest environmental impacts for the majority of the indicators tested: acidification potential (62%), eutrophication (96%), ozone depletion potential (44%), human toxicity (64%), fresh water aquatic ecotoxicity (90%) and terrestrial ecotoxicity (92%). One of the highest impacts was found to be the global warming potential (11.096 kg CO2 eq/kg AC), which was equally weighted between the steps involving impregnation, pyrolysis, and drying the washed AC. The cumulative energy demand of the AC production process from the by-product olive-waste cakes was 167.63 MJ contributed by impregnation, pyrolysis, and drying the washed AC steps. The use of phosphoric acid and electricity in the AC production were the main factors responsible for the majority of the impacts. If certain modifications are incorporated into the AC production, such as implementing synthesis gas recovery and reusing it as an energy source and recovery of phosphoric acid after AC washing, additional savings could be realized, and environmental impacts could be minimized.

Governing low-carbon energy transitions in sustainable ways: Potential synergies and conflicts between climate and environmental policy objectives

International Nuclear Information System (INIS)

Hildingsson, Roger; Johansson, Bengt

2016-01-01

Climate change is a central sustainability concern, but is often treated separately from other policy areas in environmental governance. In this article we study how low-carbon energy transitions might be governed in line with broader sustainability goals. We identify conflicts and synergies between low-carbon strategies and the attainment of longer-term environmental objectives by examining the Swedish environmental quality objectives as a governance arrangement. Our analysis indicates that low-carbon strategies might be compatible with preserving other aspects of ecological sustainability. However, this requires relevant flanking policies and measures for non-climate objectives, e.g. systems that control the expansion of biomass and ensure the use of sustainable methods. For such a governance system to be credible and capable, it needs to be flexible in terms of adapting to specific and changing contexts, and reflexive enough to factor in new knowledge on requirements for sustainable development and potentially changing values of future generations. - Highlights: • We identify synergies and conflicts between climate and environmental objectives. • Low-carbon energy transitions can be compatible with other sustainability goals. • This demands relevant flanking policies, e.g. on sustainable biomass harvesting. • This requires policy measures to take different local contexts into account. • Governance systems need to respond to new knowledge and changing values.

Environmental Public Health Tracking: a cost-effective system for characterizing the sources, distribution and public health impacts of environmental hazards.

Science.gov (United States)

Saunders, P J; Middleton, J D; Rudge, G

2017-09-01

The contemporary environment is a complex of interactions between physical, biological, socio-economic systems with major impacts on public health. However, gaps in our understanding of the causes, extent and distribution of these effects remain. The public health community in Sandwell West Midlands has collaborated to successfully develop, pilot and establish the first Environmental Public Health Tracking (EPHT) programme in Europe to address this 'environmental health gap' through systematically linking data on environmental hazards, exposures and diseases. Existing networks of environmental, health and regulatory agencies developed a suite of innovative methods to routinely share, integrate and analyse data on hazards, exposures and health outcomes to inform interventions. Effective data sharing and horizon scanning systems have been established, novel statistical methods piloted, plausible associations framed and tested, and targeted interventions informed by local concerns applied. These have influenced changes in public health practice. EPHT is a powerful tool for identifying and addressing the key environmental public health impacts at a local level. Sandwell's experience demonstrates that it can be established and operated at virtually no cost. The transfer of National Health Service epidemiological skills to local authorities in 2013 provides an opportunity to expand the programme to fully exploit its potential. © The Author 2016.

Technical, economic and environmental potential of co-firing of biomass in coal and natural gas fired power plants in the Netherlands

International Nuclear Information System (INIS)

Van Ree, R.; Korbee, R.; Eenkhoorn, S.; De Lange, T.; Groenendaal, B.

2000-01-01

In this paper the technical, economic, and environmental potential of co-firing of biomass in existing Dutch coal and natural gas fired power plants, and industrial combined-cycles (CC), is addressed. Main criteria that are considered are: the availability and contractibility of biomass for energy purposes; the (technical) operation of the conventional fossil fuel based processes may not be disturbed; the gaseous and liquid plant emissions have to comply to those applicable for power plants/CCs, the commercial applicability of the solid residues may not be negatively influenced; applicable additional biomass conversion technologies must be commercially available; the necessary additional investment costs must be acceptable from an economic point of view, and the co-firing option must result in a substantial CO 2 -emission reduction. The main result of the study described in the paper is the presentation of a clear and founded indication of the total co-firing potential of biomass in existing power plants and industrial CCs in the Netherlands. This potential is determined by considering both technical, economic, and environmental criteria. In spite of the fact that the co-firing potential for the specific Dutch situation is presented, the results of the criteria considered are more generally applicable, and therefore are also very interesting for potential co-firing initiatives outside of the Netherlands

Linking Energy- and Land-Use Systems: Energy Potentials and Environmental Risks of Using Agricultural Residues in Tanzania

Directory of Open Access Journals (Sweden)

Julia C. Terrapon-Pfaff

2012-02-01

Full Text Available This paper attempts to assess whether renewable energy self-sufficiency can be achieved in the crop production and processing sector in Tanzania and if this could be accomplished in an environmentally sustainable manner. In order to answer these questions the theoretical energy potential of process residues from commercially produced agricultural crops in Tanzania is evaluated. Furthermore, a set of sustainability indicators with focus on environmental criteria is applied to identify risks and opportunities of using these residues for energy generation. In particular, the positive and negative effects on the land-use-system (soil fertility, water use and quality, biodiversity, etc. are evaluated. The results show that energy generation with certain agricultural process residues could not only improve and secure the energy supply but could also improve the sustainability of current land-use practices.

Polyethylene plastic mulches are widely used in agriculture due to the countless advantages they have. However, the environmental problems associated with their use have led us to look for alternative mulch materials which degrade naturally and quickly, impact the environment less and function satisfactorily. To this end, biodegradable plastics and paper mulches are being used, but aspects related to their degradation should be studied more in-depth. This work provides the deterioration pattern of six biodegradable mulch materials (i.e. vegetable starch, polylactic acid plastic films or paper mulches) in horticultural crop in the edaphoclimatic conditions of Central Spain in two situations: over the lifetime of the mulches and after being incorporated into the soil. In the first situation, the deterioration levels were evaluated by recording the puncture resistance, weight and area covered in the above-soil and the in-soil part, and after soil incorporation by the number of fragments, their surfaces and weight. In the above-soil part, biodegradable plastics experienced further deterioration, particularly with no crop, while the paper mulch remained practically intact. However, the in-soil paper experienced complete and rapid degradation. At 200 days after soil incorporation, mulch residues were scarce, with the environmental effects it entails. These findings offer practical implications regarding the type of crop. The measurement of the surface covered, rather than the weight, was shown to be a more reliable indicator of the degradation of mulches. Furthermore, visual estimation was found to underestimate the functionality of mulches in comparison to that of the measurement of the surface covered. Copyright © 2017 Elsevier Ltd.

With tourism increasing in remote regions, it is important to be able to estimate potential environmental impacts from the tourists in order to plan and manage natural areas. This study combines measures of ecological sensitivity with data from publicly available geotagged photographs posted on the social media site Flickr to assess the vulnerability of the locations frequented by foreign tourists in the Westfjords region of Iceland between 2014 and 2016. The results suggest that tourists cluster primarily around six hotspots that represented some of the major known tourist destinations of the region. Although tourists generally frequented areas with lower ecological sensitivity and rarely went far beyond the main roads, one of the hotspots was in an area of higher ecological sensitivity. Further, tourists also appeared to have higher intensity stays when they entered areas of higher ecological sensitivity. Overall, these findings highlight the usefulness of combining data from social media in assessing potential environmental impacts of tourism. However, natural resource managers should be aware of limitations in the use of such data.

Given the crucial role of microbiota in host development, health, and environmental interactions, genomic analyses focusing on host-microbiota interactions should certainly be considered in the investigation of the adaptive mechanisms to environmental stress. Recently, several studies suggested that microbiota associated to digestive tract is a key, although still not fully understood, player that must be considered to assess the toxicity of environmental contaminants. Bacteria-dependent metabolism of xenobiotics may indeed modulate the host toxicity. Conversely, environmental variables (including pollution) may alter the microbial community and/or its metabolic activity leading to host physiological alterations that may contribute to their toxicity. Here, 16s rRNA gene amplicon sequencing has been applied to characterize the hepatopancreas microbiota composition of the Manila clam, Ruditapes philippinarum. The animals were collected in the Venice lagoon area, which is subject to different anthropogenic pressures, mainly represented by the industrial activities of Porto Marghera (PM). Seasonal and geographic differences in clam microbiotas were explored and linked to host response to chemical stress identified in a previous study at the transcriptome level, establishing potential interactions among hosts, microbes, and environmental parameters. The obtained results showed the recurrent presence of putatively detoxifying bacterial taxa in PM clams during winter and over-representation of several metabolic pathways involved in xenobiotic degradation, which suggested the potential for host-microbial synergistic detoxifying actions. Strong interaction between seasonal and chemically-induced responses was also observed, which partially obscured such potentially synergistic actions. Seasonal variables and exposure to toxicants were therefore shown to interact and substantially affect clam microbiota, which appeared to mirror host response to environmental variation. It

Hak Asasi Manusia (Human Rights dalam Menangani Krisis Alam Sekitar: Perspektif Seyyed Hossein Nasr

Full Text Available ‘Human rights’ are the basic rights and fundamental freedoms. Today’s human rights movements also concern on nature in resolving the environmental crisis. Within the freedom of thought and expression, this trend has extended dramatically in recent years, as many people have been surrounded by massive pollutions such as global warming and water crisis. Many environments have been greatly altered by human activities. On the right track, scholars and scientists have taken risks to test so many ideas and approaches that could lead to exponential changes to improve or even preserve the natural environment. Although ‘human rights’ has been used popularly in recent decades, Seyyed Hossein Nasr argues that the term should be blamed for the environmental crisis we are presently facing. As one of the most important and foremost Muslim philosophers in the world today, Nasr emphasizes that the environmental crisis is created by the crisis of human value in their philosophy of human rights based on human ‘freedom’. Nasr’s writings on human rights can be observed in his Islam and the Environmental Crisis (1990, Islam and the Challenge of the 21st Century (1993 and Religion and the Order of Nature (1996. This semantic study is to show that human rights’ philosophy is too dangerous to nature, tracking on the unconditional absolute rights. Through semantic analysis, the study finds that ‘human rights’ are related to secular philosophy which enthrones the unlimited human freedom, and at the same time against the order of nature as Divine Order.

Neglected Population, Neglected Right: Children Living with HIV and the Right to Science.

The laws, language, and tools of human rights have been instrumental in expanding access to lifesaving treatment for people living with HIV. Children, however, remain a neglected population, as evidenced by inadequate child-specific and child-friendly HIV treatment options. In this article, we explore the right to science, a potentially powerful but underdeveloped right in international law, and its application to research and development for pediatric HIV treatment. Drawing on reports of human rights bodies and scholars and applying the human rights typology of state obligations to respect, protect, and fulfill, we argue that states have five core obligations related to research and development for child-specific and child-friendly treatment: (1) adopting a public goods approach to science and science policy; (2) including and protecting children in research activities; (3) adopting legal and policy frameworks to support research and development through public funding and private sector incentives; (4) promoting international cooperation and assistance; and (5) ensuring the participation of marginalized communities in decision-making processes. In concluding, we make a number of recommendations for states, human rights bodies, international organizations, civil society, and private industry to further develop and implement the right to science.

The West African outbreak of Ebola virus (EBOV) is largely contained, but sporadic new cases continue to emerge. To assess the potential contribution of fomites to human infections with EBOV, we tested EBOV stability in human blood spotted onto Sierra Leonean banknotes and in syringe needles under hospital and environmental conditions. Under some of these conditions, EBOV remained infectious for >30 days, indicating that EBOV-contaminated items may pose a serious risk to humans. © The Author 2016.

Environmental enrichment improves learning and memory and long-term potentiation in young adult rats through a mechanism requiring mGluR5 signaling and sustained activation of p70s6k.

Science.gov (United States)

Hullinger, Rikki; O'Riordan, Kenneth; Burger, Corinna

2015-11-01

Previous studies from our lab have demonstrated that mild cognitive impairments identified early in life are predictive of cognitive deficits that develop with age, suggesting that enhancements in cognition at an early age can provide a buffer against age-related cognitive decline. Environmental enrichment has been shown to improve learning and memory in the rodent, but the impact of enrichment on synaptic plasticity and the molecular mechanisms behind enrichment are not completely understood. To address these unresolved issues, we have housed 2-month old rats in environmentally enriched (EE), socially enriched (SE), or standard housing (SC) and conducted tests of learning and memory formation at various time intervals. Here we demonstrate that animals that have been exposed to one month of social or environmental enrichment demonstrate enhanced learning and memory relative to standard housed controls. However, we have found that after 4months EE animals perform better than both SE and SC groups and demonstrate an enhanced hippocampal LTP. Our results demonstrate that this LTP is dependent on mGluR5 signaling, activation of ERK and mTOR signaling cascades, and sustained phosphorylation of p70s6 kinase, thus providing a potential target mechanism for future studies of cognitive enhancement in the rodent.

2017-01-01

In this short review, we want to summarize the current findings on the role of vitamin-D in multiple sclerosis (MS), schizophrenia, and autism. Many studies have highlighted hypovitaminosis-D as a potential environmental risk factor for a variety of conditions such as MS, asthma, cardiovascular disease, and, more recently, psychiatric diseases. However, whether hypovitaminosis-D is a potential causative factor for the development or activity in these conditions or whether hypovitaminosis-D may be due to increased vitamin-D consumption by an activated immune system (reverse causation) is the focus of intense research. Here, we will discuss current evidence exploring the role of vitamin-D in MS, schizophrenia, and autism and its impact on adaptive and innate immunity, antimicrobial defense, the microbiome, neuroinflammation, behavior, and neurogenesis. More work is needed to gain insight into its role in the underlying pathophysiology of these conditions as it may offer attractive means of intervention and prevention.

The traveler presented a paper on The Fate of Radionuclides in Sewage Sludge Applied to Land.'' Those findings corresponded well with results from studies addressing the fate of fallout radionuclides from the Chernobyl nuclear accident. There was an exchange of new information on a number of topics of interest to DOE waste management and environmental restoration needs.

Potential use of calcareous mudstones in low hydraulic conductivity earthen barriers for environmental applications.

Earthen layers play a significant role in isolating contaminants in the subsurface, controlling the migration of contaminant plumes, and as landfill liners and covers. The physical, chemical and mineralogical properties of three calcareous mudstones from the Jagüel and Roca formations in North Patagonia, Argentina, are evaluated to determine their potential for the construction of liners. These mudstones were deposited in a marine environment in the Upper Cretaceous-Paleocene. The tested specimens mainly comprise silt and clay-sized particles, and their mineralogy is dominated by a smectite/illite mixed layer (70-90% Sm) and calcite in smaller proportion. Powdered mudstone samples have little viscosity and swelling potential when suspended in water. The hydraulic conductivity of compacted mudstones and sand-mudstone mixtures is very low (around 1-3 x 10(-10) m/s) and in good agreement with the expected hydraulic behaviour of compacted earthen layers. This behaviour can be attributed to the large amount of fine particles, high specific surface and the close packing of particles as confirmed by scanning electron microscope analysis. The tested materials also show a high cation exchange capacity (50-70 cmol/kg), indicating a high contaminant retardation capability. The calcareous mudstones show satisfactory mineralogical and chemical properties as well as an adequate hydraulic behaviour, demonstrating the potential use of these materials for the construction of compacted liners for the containment of leachate or as covers in landfills. These findings confirm the potential usage of marine calcareous mudstones as a low-cost geomaterial in environmental engineering projects.

The Tobacco Industry and Children's Rights.

van der Eijk, Yvette; Bialous, Stella A; Glantz, Stanton

The manufacture, use, and marketing of tobacco present a serious threat to children's right to health. This makes the Convention on the Rights of the Child a potentially powerful tobacco-control tool and the United Nations Children's Fund (UNICEF), which oversees the convention's implementation, a potential leader in tobacco control. UNICEF actively supported tobacco control initiatives in the late 1990s, but since the early 2000s UNICEF's role in tobacco control has been minimal. Using the Truth Tobacco Industry Documents library, an online collection of previously secret tobacco industry documents, we sought to uncover information on the tobacco industry's ties with UNICEF. We found that from 1997 to 2000, when UNICEF was actively promoting tobacco control to support children's rights, the tobacco industry saw children's rights and UNICEF as potentially powerful threats to business that needed to be closely monitored and neutralized. The industry then positioned itself as a partner with UNICEF on youth smoking prevention initiatives as a way to avoid meaningful tobacco control measures that could save children's lives. After UNICEF's corporate engagement guidelines were loosened in 2003, tobacco companies successfully engaged with UNICEF directly and via front groups, including the Eliminating Child Labour in Tobacco Growing Foundation. This was part of an overall tobacco industry strategy to improve its corporate image, infiltrate the United Nations, and weaken global tobacco-control efforts. As part of its mission to protect children's rights, UNICEF should end all partnerships with the tobacco industry and its front groups. Copyright © 2018 by the American Academy of Pediatrics.

ENVIRONMENTAL EFFECT OF SUDAN I-IV: ADSORPTION BEHAVIORS AND POTENTIAL RISK ON SOIL

Full Text Available Sudan dyes (Table 1 [1], a class of synthetic azo dyes and classified as category 3 carcinogens by the International Agency for Research on Cancer[2], have been received considerable attention all over the world, especially in the past decade, which are found to be non-authorized and illegally added into food products, such as chili-, curry-, curcuma- and palm oil-containing foodstuffs, meats, spice mix, as well as feedstuffs and feed poultry, to enhance or maintain the appearance due to their intensive color and low price[3,4]. In addition, they are extensively applied in industrial and scientific areas, such as oils, textiles, plastics, waxes, inks, films, cosmetic products, shoe and floor polishing, and spirit varnishing[5-7]. Obviously, there exist a variety of potential sources for environmental contamination by Sudan dyes, thus threatening human health and the safety of ecosystems. It is reported that sub parts per billion levels of Sudan dyes were present in paprika fruits during the vegetation process, particularly, Sudan I existed in almost all samples, including paprika fruits, soils and agronomic materials from some fields in China[8],the levels in soils were significantly elevated by vegetation treatments, and pesticides and fertilizers constitute the major source of Sudan I contamination[9]. Till now, the investigation on contaminative behavior and environmental effects is rarely involved, and biogeochemical cycles of Sudan dyes are rarely concerned either.

Assessment of right atrial function analysis

To assess the potential utility of right atrial function analysis in cardiac disease, reservoir function, pump function, and right atrial peak emptying rate (RAPER) were compared in 10 normal subjects, 32 patients with coronary artery disease, and 4 patients with primary pulmonary hypertension. Right atrial volume curves were obtained using cardiac radionuclide method with Kr-81m. In normal subjects, reservoir function index was 0.41+-0.05; pump function index was 0.25+-0.05. Both types of patients has decreased reservoir funcion and increased pump function. Pump function tended to decrease with an increase of right ventricular end-diastolic pressure. RAPER correlated well with right ventricular peak filling rate, probably reflecting right ventricular diastolic function. Analysis of right atrial function seemed to be of value in evaluating factors regulating right ventricular contraction and diastolic function, and cardiac output. (Namekawa, K)

Full Text Available The article discusses the problems associated with introduction of new administrative approaches to solid waste management, as well as the choice of priority directions in the development of the regional waste treatment schemes, which may increase the efficiency of the environmental sector in the city (region and improve the ecology in general. The authors analyze the factors, which may lead to environmental deterioration and endanger the ecological safety of Yekaterinburg and Sverdlovsk Oblast. They also highlight the priority challenges, one of which is utilization of the biogas produced in the municipal solid waste landfills. In the context of the existing administrative districts, the paper analyzes the results of calculations of biogas production and emissions from the waste incineration plants in Yekaterinburg and Sverdlovsk Oblast. The authors offer an algorithm, which helps to evaluate the reduction of methane emissions to the atmosphere after introduction of a biogas combustion technology. The article also discusses the author’s recommendations on how to justify the directions in the development of the regional waste management schemes, which will increase the efficiency of the companies operating in the field of waste management.

Environmental epigenetics: A promising venue for developing next-generation pollution biomonitoring tools in marine invertebrates.

Suarez-Ulloa, Victoria; Gonzalez-Romero, Rodrigo; Eirin-Lopez, Jose M

2015-09-15

Environmental epigenetics investigates the cause-effect relationships between specific environmental factors and the subsequent epigenetic modifications triggering adaptive responses in the cell. Given the dynamic and potentially reversible nature of the different types of epigenetic marks, environmental epigenetics constitutes a promising venue for developing fast and sensible biomonitoring programs. Indeed, several epigenetic biomarkers have been successfully developed and applied in traditional model organisms (e.g., human and mouse). Nevertheless, the lack of epigenetic knowledge in other ecologically and environmentally relevant organisms has hampered the application of these tools in a broader range of ecosystems, most notably in the marine environment. Fortunately, that scenario is now changing thanks to the growing availability of complete reference genome sequences along with the development of high-throughput DNA sequencing and bioinformatic methods. Altogether, these resources make the epigenetic study of marine organisms (and more specifically marine invertebrates) a reality. By building on this knowledge, the present work provides a timely perspective highlighting the extraordinary potential of environmental epigenetic analyses as a promising source of rapid and sensible tools for pollution biomonitoring, using marine invertebrates as sentinel organisms. This strategy represents an innovative, groundbreaking approach, improving the conservation and management of natural resources in the oceans. Copyright © 2015 Elsevier Ltd. All rights reserved.

Intermodal Freight Transport on the Right Track? Environmental and economic performances and their trade-off

International Nuclear Information System (INIS)

Kim, Nam Seok

2010-01-01

This dissertation aims to evaluate environmental and economic performances of an intermodal freight transport system and to estimate the trade-off between CO2 emissions, which is presented as an indicator of environmental performance, and freight costs, which indicate the economic performance of the intermodal freight system. The truck-only system is always regarded as the counterpart of the intermodal freight system in this dissertation. To examine the environmental performance of the intermodal freight system, CO2 emissions generated from all the processes in the intermodal chain, such as pre-haulage and post-haulage, long distance haulage, and transshipment, are estimated considering different sources that generate electricity and transmission loss of electricity (Chapters 3 and 4). To examine the economic performance of the system, two approaches are considered: (1) finding the intermodal breakeven distance for which the intermodal system is more competitive than the truck-only system (Chapter 5); (2) examining the economies of scale in the intermodal network and finding the route/system choice that minimizes the total freight transportation costs (Chapter 6). Finally, this dissertation attempts to find the trade-off between CO2 emissions (representing the environmental performance) and freight transportation cost (representing the economic performance) (Chapter 7)

Environmental audits of oil and gas properties

International Nuclear Information System (INIS)

Moody, T.D.; Forbes, S.

1991-01-01

The growing concern over one, the cost of correcting environmental damage and two, the potential financial liabilities associated with the acquisition, sale or lease of oil and gas properties, has led many prospective buyers to investigate the environmental liabilities associated with the property transfer. The environmental audit provides a tool or mechanism to assist the prudent investor in identifying environmental problems that could adversely effect an otherwise normal business activity. Accordingly, an environmental audit can identify potential environmental liabilities associated with the property, thus allowing the investor an opportunity to better assess financial risks. In addition, should the negative findings of the environmental audit be limited, the findings could be used by the buyer in negotiating the final price of the subject property to account for potential or known liabilities. As this suggests, environmental damage to an oil and gas property does not necessarily render the property worthless. This paper provides a brief guide on environmental audits of oil and gas properties as well as general information on the most common exploration and production wastes

The Federal Environment Agency (UBA) in Germany as one Competent Authority of the European Member States involved with the assessment and authorisation of chemicals, pesticides, biozides and medicals, has a wide expertise of complex information systems. Having timely, comprehensive and reliable information on the environmental relevant properties (e.g. of chemical substances and preparations) is of immense importance for all sections dealing with environmental protection issues. Regarding the reality of available information systems in each environmental section, and moreover in each section itself, there has been developed several specific approaches to gather, store and search its relevant data. This makes sense due to each section has its own requirements, different user groups (industry and authorities or just authorities or scientific partners etc.), different budgets to bring technology 'on the road', and different (legally obligatory) procedures to handle the data and information of such systems. Nevertheless, there several strong reasons to look for a Linked Environmental Data infrastructure - at least internally in one authority itself: - Overcome the mostly separated systems; - Explore the potential of data silos in several environmental sections; - Efficiency/effectiveness in data gathering, assessment, results, budgets..; - sharing of knowledge, i.e. use of specific prepared information of specially intended information systems; - timelyness of data/information; - best data/information from most competent partner/section; - gain from already available systems and their data/information; - speed up developments and availability of data/information. Of course there are also several points which might be a huge obstacle to Linked Environmental Data (LED), e.g. confidential business data. This leads already to the distinction between 'Open LED' and 'Non-Open LED'. Nevertheless, the potential benefits and the possibilities offered via the modern information

Bioenergy development pathways for Europe. Potentials, costs and environmental impacts

Energy Technology Data Exchange (ETDEWEB)

De Wit, M.P.

2011-09-26

Fossil resources dominate the global energy system today which cannot be sustained indefinitely. Bioenergy use can meet a large share of future energy supply sustainably. For example, it can substitute fossil fuels including petroleum, and when sustainably produced, bioenergy avoids greenhouse gas emissions. However, with the recent increase of modern bioenergy use several drawbacks have become apparent that may lead to negative ecological impacts. Europe plays an important role in the further sustainable development of bioenergy due to its ambitious renewable energy policies and its state-of-the-art agricultural sector. The main objective of this thesis is to evaluate development pathways for bioenergy in Europe by assessing preconditions for its development, an economic outlook for such development and an assessment of its environmental implications. The technical European biomass potential has a substantial potential to contribute to Europe's energy consumption. Energy crop production on European croplands and grasslands supplemented with agricultural and forestry residues offers an ultimate technical potential of 27.7 EJ y-1. These findings were based on the assumption that agricultural land needs for future domestic food production decrease as productivities per hectare increase. Central and Eastern Europe pose the more attractive region with relatively high potentials and low costs. In European agriculture, it is possible to combine large-scale biomass production with food production sustained at current levels, without direct or indirect land-use changes and while accomplishing significant net cumulative greenhouse gas emission reductions when both bioenergy and agricultural production are considered. To accomplish this situation two preconditions need to be met: a gradual intensification of food production and implementation of structural improvements to agricultural management. Based on the current economic performance and future prospects for

Collaborative governance critics continually call for evidence to support its prevalent use. As is often the case in environmental policy, environmental outcomes occur at a rate incompatible with political agendas. In addition, a multitude of possibly confounding variables makes it difficult to correlate collaborative governance processes with environmental outcomes. The findings of this study offer empirical evidence that collaborative processes have a measurable, beneficial effect on environmental outcomes. Through the use of a unique paired-waterbody design, our dataset reduced the potential for confounding variables to impact our environmental outcome measurements. The results of a path analysis indicate that the output of setting specific pollutant reduction goals is significantly related to watershed partnerships' level of attainment of their environmental improvement goals. The action of setting specific goals (e.g. percentage of load reductions in pollutant levels) is fostered by sustained participation from partnership members throughout the lifecycle of the collaborative. In addition, this study demonstrates the utility of logic modeling for environmental planning and management, and suggests that the process of setting specific pollutant reduction goals is a useful proxy measure for reporting progress towards improvements in environmental outcomes when long-term environmental data are not available.

Developing markets for forest environmental services: an opportunity for promoting equity while securing efficiency?

Science.gov (United States)

Landell-Mills, Natasha

2002-08-15

Market-based approaches to environmental management are all the rage. Claims that market mechanisms can encourage environmental protection and promote greater economic efficiency while saving taxpayers' money are tantalizing. In the forestry sector, policy makers are widely heeding this advice and shrinking command-and-control systems in favour of incentive mechanisms that seek to align private enthusiasm with the public good. In some cases, governments are even promoting the creation of markets where none existed before. In others, markets are evolving of their own accord. In such times of change, it is difficult to stand back and take stock. Yet, it is during such times that guidance is most needed. In the rush to introduce market-based solutions to environmental problems, a particular concern is how markets are impacting on the poor. In this paper an effort is made to draw on a recent review of markets for four forest environmental services (biodiversity conservation, carbon sequestration, watershed protection and landscape beauty) to draw out preliminary insights into how markets are performing with respect to their impacts on the poor. The evidence suggests a need for caution. While the potential benefits are significant, the poor face an uphill battle in realizing them. Key constraints facing the poor include a lack of property rights over forest resources and their environmental services; inadequate skills and education; poor market information; lack of market contacts; inadequate communication infrastructure; inappropriate contract design; and lack of access to financial resources. To tackle these, four potential ways forward are highlighted: (1) assign property rights to forest assets and their related environmental services in ways that respect customary arrangements and poor people's tenure; (2) strengthen capacity for market participation, e.g. through training and education; (3) invest in the provision of market information, advice and, essentially, a

Large quantities of free protein in the environment and other bioaerosols are ubiquitous throughout terrestrial ground level environments and may be integrative indicators of ecosystem status. Samples of ground level bioaerosols were collected from various ecosystems throughout Ecuador, including pristine humid tropical forest (pristine), highly altered secondary humid tropical forest (highly altered), secondary transitional very humid forest (regrowth transitional), and suburban dry montane deforested (suburban deforested). The results explored the sensitivity of localized aerosol protein concentrations to spatial and temporal variations within ecosystems, and their value for assessing environmental change. Ecosystem specific variations in environmental protein concentrations were observed: pristine 0.32 ± 0.09 μg/m3, highly altered 0.07 ± 0.05 μg/m3, regrowth transitional 0.17 ± 0.06 μg/m3, and suburban deforested 0.09 ± 0.04 μg/m3. Additionally, comparisons of intra-environmental differences in seasonal/daily weather (dry season 0.08 ± 0.03 μg/m3 and wet season 0.10 ± 0.04 μg/m3), environmental fragmentation (buffered 0.19 ± 0.06 μg/m3 and edge 0.15 ± 0.06 μg/m3), and sampling height (ground level 0.32 ± 0.09 μg/m3 and 10 m 0.24 ± 0.04 μg/m3) demonstrated the sensitivity of protein concentrations to environmental conditions. Local protein concentrations in altered environments correlated well with satellite-based spectral indices describing vegetation productivity: normalized difference vegetation index (NDVI) (r2 = 0.801), net primary production (NPP) (r2 = 0.827), leaf area index (LAI) (r2 = 0.410). Moreover, protein concentrations distinguished the pristine site, which was not differentiated in spectral indices, potentially due to spectral saturation typical of highly vegetated environments. Bioaerosol concentrations represent an inexpensive method to increase understanding of environmental changes, especially in densely vegetated

Review of potential environmental impacts of transgenic glyphosate-resistant soybean in Brazil.

Transgenic glyphosate-resistant soybeans (GRS) have been commercialized and grown extensively in the Western Hemisphere, including Brazil. Worldwide, several studies have shown that previous and potential effects of glyphosate on contamination of soil, water, and air are minimal, compared to those caused by the herbicides that they replace when GRS are adopted. In the USA and Argentina, the advent of glyphosate-resistant soybeans resulted in a significant shift to reduced- and no-tillage practices, thereby significantly reducing environmental degradation by agriculture. Similar shifts in tillage practiced with GRS might be expected in Brazil. Transgenes encoding glyphosate resistance in soybeans are highly unlikely to be a risk to wild plant species in Brazil. Soybean is almost completely self-pollinated and is a non-native species in Brazil, without wild relatives, making introgression of transgenes from GRS virtually impossible. Probably the highest agricultural risk in adopting GRS in Brazil is related to weed resistance. Weed species in GRS fields have shifted in Brazil to those that can more successfully withstand glyphosate or to those that avoid the time of its application. These include Chamaesyce hirta (erva-de-Santa-Luzia), Commelina benghalensis (trapoeraba), Spermacoce latifolia (erva-quente), Richardia brasiliensis (poaia-branca), and Ipomoea spp. (corda-de-viola). Four weed species, Conyza bonariensis, Conyza Canadensis (buva), Lolium multiflorum (azevem), and Euphorbia heterophylla (amendoim bravo), have evolved resistance to glyphosate in GRS in Brazil and have great potential to become problems.

Mesenteric phlebosclerosis is a rare ischemic disease affecting the colon. Systemic disease and herbal medicine have been pointed out as possible causes, and the disease is characterized by calcifications involved the mesocolic veins. Patients who do not respond to conservative therapy require surgical treatment. In surgical intervention, an adequate extent of colonic resection is important. We present a case of an 87-year-old woman with mesenteric phlebosclerosis who had consumed herbal medicine for 40 years. She suffered from ileus caused by mesenteric phlebosclerosis, and the symptoms did not improve with conservative therapy. Right hemicolectomy was performed since the disease was localized in the right colon. Long-term use of herbal medicine was considered the potential cause of mesenteric phlebosclerosis. The postoperative course was mostly uneventful. The patient stopped using herbal medicine and had no signs of recurrence 2 years after surgery. The greatest concern in surgery for mesenteric phleboscrerosis is to detect the affected area, which should be removed. Characteristic findings in computed tomography and intraoperative findings can help to determine the optimal extent of colonic resection. Mesenteric phlebosclerosis caused by herbal medicines occurs as localized disease in the right colon compared with mesenteric phlebosclerosis caused by other pathogenesis. Limited colonic resection is usually indicated for mesenteric phlebosclerosis caused by herbal medicine. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Graphical Methodology of Global Pollution Index for the Environmental Impact Assessment Using Two Environmental Components

Directory of Open Access Journals (Sweden)

Corneliu Cojocaru

2017-04-01

Full Text Available One of the applied methods for environmental impact assessment is the index of global pollution (IGP proposed by Rojanschi in 1991. This methodology enables the global estimation for the ecosystem state affected more or less by human activities. Unfortunately, Rojanschi’s method has a limitation; it can be applied only if at least three environmental components are considered. Frequently, many environmental impact assessment applications rely on analysis of only two environmental components. Therefore, this work aimed to develop a new graphical method to extend Rojanschi’s approach for the case of two environmental components. The proposed method avoids the average value of evaluation grades and uses only the graphical correspondence for calculation of the index of global pollution. A right-angle triangle graph methodology was proposed, where bases represented the values of evaluation grades. Thus, for the case of two environmental components, the index of global pollution was calculated as the relation between the ideal and real ecosystem states represented by the ratio between areas of external and enclosed right triangles. The developed graphical method was tested and validated for real case studies: the environmental impact assessment from a refinery located on the Romanian Black Sea Coast considering Air and Water environmental components and from a coal-fired thermoelectric power plant from Eastern Romania regarding Air and Soil environmental components. In this way, it was provided a reliable and faster tool to be used for the pollution characterization of human-derived chemicals for better decisions in risk management.

As part of the Halifax Project, this review brings attention to the potential effects of environmental chemicals on important molecular and cellular regulators of the cancer hallmark of evading growth suppression. Specifically, we review the mechanisms by which cancer cells escape the growth-inhibitory signals of p53, retinoblastoma protein, transforming growth factor-beta, gap junctions and contact inhibition. We discuss the effects of selected environmental chemicals on these mechanisms of growth inhibition and cross-reference the effects of these chemicals in other classical cancer hallmarks. © The Author 2015.

The development of new resources to evaluate the environmental status is becoming increasingly important representing a key challenge for ocean and coastal management. Recently, the employment of transcriptomics in aquatic toxicology has led to increasing initiatives proposing to integrate eco-toxicogenomics in the evaluation of marine ecosystem health. However, several technical issues need to be addressed before introducing genomics as a reliable tool in regulatory ecotoxicology. The Venice lagoon constitutes an excellent case, in which the assessment of environmental risks derived from the nearby industrial activities represents a crucial task. In this context, the potential role of genomics to assist environmental monitoring was investigated through the definition of reliable gene expression markers associated to chemical contamination in Manila clams, and their subsequent employment for the classification of Venice lagoon areas. Overall, the present study addresses key issues to evaluate the future outlooks of genomics in the environmental monitoring and risk assessment. Copyright © 2014 Elsevier Ltd. All rights reserved.

Arsenic, cadmium and lead in aerosols, dusts and surface soils from Australia's oldest continuous lead mining town of Broken Hill were compared to standardised national childhood developmental (year 1) and education performance measures (years 3,5,7,9). Contaminants close to mining operations were elevated with maximum lead levels in soil: 8900 mg/kg; dust wipe: 86,061 μg/m(2); dust deposition: 2950 μg/m(2)/day; aerosols: 0.707 μg/m(3). The proportion of children from Broken Hill central, the area with the highest environmental contamination, presented with vulnerabilities in two or more developmental areas at 2.6 times the national average. Compared with other school catchments of Broken Hill, children in years 3 and 5 from the most contaminated school catchment returned consistently the lowest educational scores. By contrast, children living and attending schools associated with lower environmental contamination levels recorded higher school scores and lower developmental vulnerabilities. Similar results were identified in Australia's two other major lead mining and smelting cities of Port Pirie and Mount Isa. Copyright © 2015 Elsevier Ltd. All rights reserved.

Implications of movement for species distribution models - Rethinking environmental data tools.

Movement is considered an essential process in shaping the distributions of species. Nevertheless, most species distribution models (SDMs) still focus solely on environment-species relationships to predict the occurrence of species. Furthermore, the currently used indirect estimates of movement allow to assess habitat accessibility, but do not provide an accurate description of movement. Better proxies of movement are needed to assess the dispersal potential of individual species and to gain a more practical insight in the interconnectivity of communities. Telemetry techniques are rapidly evolving and highly capable to provide explicit descriptions of movement, but their usefulness for SDMs will mainly depend on the ability of these models to deal with hitherto unconsidered ecological processes. More specifically, the integration of movement is likely to affect the environmental data requirements as the connection between environmental and biological data is crucial to provide reliable results. Mobility implies the occupancy of a continuum of space, hence an adequate representation of both geographical and environmental space is paramount to study mobile species distributions. In this context, environmental models, remote sensing techniques and animal-borne environmental sensors are discussed as potential techniques to obtain suitable environmental data. In order to provide an in-depth review of the aforementioned methods, we have chosen to use the modelling of fish distributions as a case study. The high mobility of fish and the often highly variable nature of the aquatic environment generally complicate model development, making it an adequate subject for research. Furthermore, insight into the distribution of fish is of great interest for fish stock assessments and water management worldwide, underlining its practical relevance. Copyright © 2018 Elsevier B.V.

Potential Environmental and Ecological Effects of Global Climate Change on Venomous Terrestrial Species in the Wilderness.

Needleman, Robert K; Neylan, Isabelle P; Erickson, Timothy

2018-06-01

Climate change has been scientifically documented, and its effects on wildlife have been prognosticated. We sought to predict the overall impact of climate change on venomous terrestrial species. We hypothesize that given the close relationship between terrestrial venomous species and climate, a changing global environment may result in increased species migration, geographical redistribution, and longer seasons for envenomation, which would have repercussions on human health. A retrospective analysis of environmental, ecological, and medical literature was performed with a focus on climate change, toxinology, and future modeling specific to venomous terrestrial creatures. Species included venomous reptiles, snakes, arthropods, spiders, and Hymenoptera (ants and bees). Animals that are vectors of hemorrhagic infectious disease (eg, mosquitos, ticks) were excluded. Our review of the literature indicates that changes to climatic norms will have a potentially dramatic effect on terrestrial venomous creatures. Empirical evidence demonstrates that geographic distributions of many species have already shifted due to changing climatic conditions. Given that most terrestrial venomous species are ectotherms closely tied to ambient temperature, and that climate change is shifting temperature zones away from the equator, further significant distribution and population changes should be anticipated. For those species able to migrate to match the changing temperatures, new geographical locations may open. For those species with limited distribution capabilities, the rate of climate change may accelerate faster than species can adapt, causing population declines. Specifically, poisonous snakes and spiders will likely maintain their population numbers but will shift their geographic distribution to traditionally temperate zones more often inhabited by humans. Fire ants and Africanized honey bees are expected to have an expanded range distribution due to predicted warming trends

The secretion of antimicrobial compounds is an ancient mechanism with clear survival benefits for microbes competing with other microorganisms. Consequently, mechanisms that confer resistance are also ancient and may represent an underestimated reservoir in environmental bacteria. In this context, β-lactamases (BLs) are of great interest due to their long-term presence and diversification in the hospital environment, leading to the emergence of Gram-negative pathogens that are resistant to cephalosporins (extended spectrum BLs = ESBLs) and carbapenems (carbapenemases). In the current study, protein sequence databases were used to analyze BLs, and the results revealed a substantial number of unknown and functionally uncharacterized BLs in a multitude of environmental and pathogenic species. Together, these BLs represent an uncharacterized reservoir of potentially transferable resistance genes. Considering all available data, in silico approaches appear to more adequately reflect a given resistome than analyses of limited datasets. This approach leads to a more precise definition of BL clades and conserved motifs. Moreover, it may support the prediction of new resistance determinants and improve the tailored development of robust molecular diagnostics.

In the shadow of the Cosmetic Directive--inconsistencies in EU environmental hazard classification requirements for UV-filters.

UV-filters are chemicals with potentially environmental hazardous properties. In the European Union (EU), UV-filters contained in sunscreen products are currently regulated by the Cosmetic Directive (from July 2013 by the Cosmetic Products Regulation). Environmental hazard classifications according to the regulation on classification, labelling and packaging of substances and mixtures (CLP) must be determined for UV-filters contained in industrial chemical products, whereas UV-filters contained in sunscreens are exempted from CLP. In this study we determined the potential environmental hazard classifications of UV-filters and sunscreen products if the CLP regulation was to be required for cosmetic products. Two sunscreen products were evaluated in accordance with the aquatic environmental hazard criteria for mixtures. The results highlight that the inconsistencies in the current EU regulation of UV filters hamper the risk management of environmental hazards of UV filters used in cosmetic products. Almost 50% of the investigated UV-filters approved for use in cosmetic products on the European market according to the current Cosmetic Directive were identified to meet the CLP classification as being hazardous to the aquatic environment. Assuming a worst-case scenario, the two examined sunscreens could both be classified as hazardous to the aquatic environment with long-lasting effects according to CLP classification criteria. Hence, if the CLP regulation was applicable to sunscreen products, both brands could potentially be labelled with the environmental hazard pictogram and associated hazard and precautionary statements. Including cosmetic products, and thereby sunscreens, in the CLP regulation would contribute to a more harmonized and transparent regulation of potentially hazardous substances on the EU market.

The hydroelectric potential of a river is proportional to its head and water flows. Selecting the best development alternative for Greenfield projects watersheds is a difficult task, since it must balance demands for infrastructure, especially in the developing world where a large potential remains unexplored, with environmental conservation. Discussions usually diverge into antagonistic views, as in recent projects in the Amazon forest, for example. This motivates the construction of a computational tool that will support a more qualified debate regarding development/conservation options. HERA provides the optimal head division partition of a river considering technical, economic and environmental aspects. HERA has three main components: (i) pre-processing GIS of topographic and hydrologic data; (ii) automatic engineering and equipment design and budget estimation for candidate projects; (iii) translation of division-partition problem into a mathematical programming model. By integrating an automatic calculation with geoprocessing tools, cloud computation and optimization techniques, HERA makes it possible countless head partition division alternatives to be intrinsically compared - a great advantage with respect to traditional field surveys followed by engineering design methods. Based on optimization techniques, HERA determines which hydro plants should be built, including location, design, technical data (e.g. water head, reservoir area and volume, engineering design (dam, spillways, etc.) and costs). The results can be visualized in the HERA interface, exported to GIS software, Google Earth or CAD systems. HERA has a global scope of application since the main input data area a Digital Terrain Model and water inflows at gauging stations. The objective is to contribute to an increased rationality of decisions by presenting to the stakeholders a clear and quantitative view of the alternatives, their opportunities and threats.

The complex nature of freshwater systems provides challenges for incorporating evidence-based techniques into management. This paper investigates the potential of participatory evidence-based techniques to involve local stakeholders and make decisions based on different "knowledge" sources within adaptive management programs. It focuses on the application of thresholds of potential concern (TPC) within strategic adaptive management (SAM) for facilitating inclusive decision-making. The study is based on the case of the Edward-Wakool (E-W) "Fish and Flows" SAM project in the Murray-Darling River Basin, Australia. We demonstrate the application of TPCs for improving collaborative decision-making within the E-W, associated with environmental watering requirements, and other natural resource management programs such as fish stocking. The development of TPCs in the E-W fish and flows SAM project helped improve stakeholder involvement and understanding of the system, and also the effectiveness of the implemented management interventions. TPCs ultimately helped inform environmental flow management activities. The TPC process complemented monitoring that was already occurring in the system and provided a mechanism for linking formal and informal knowledge to form explicit and measurable endpoints from objectives. The TPC process faced challenges due to the perceived reduction in scientific rigor within initial TPC development and use. However, TPCs must remain tangible to managers and other stakeholders, in order to aid in the implementation of adaptive management. Once accepted by stakeholders, over time TPCs should be reviewed and refined in order to increase their scientific rigor, as new information is generated.

2017-07-31

Growing evidence indicates that exposure to widespread, environmental contaminants called endocrine disruptors (EDCs) negatively affects animal and human reproductive health and has been linked to several diseases including infertility. This review aims to evaluate the impact of environmental exposure to endocrine disrupting chemicals [phthalates, parabens, triclosan, bisphenol A (BPA), organochlorine (PCBs) and perfluorinated (PFCs) compounds] on the reproductive potential among women, by reviewing most recently published literature. Epidemiological studies focusing on EDCs exposure and reproductive potential among women for the last 16 years were identified by a search of the PUBMED, MEDLINE, EBSCO and TOXNET literature databases. The results of the presented studies show that exposure to EDCs impacts the reproductive potential in women, measured by ovarian reserve and by assisted reproductive technology outcomes. Exposure to environmental endocrine disrupting chemicals decrease: (i) oestradiol levels (BPA); (ii) anti-Müllerian hormone concentrations (PCBs); (iii) antral follicle count (BPA, parabens, phthalates); (iv) oocyte quality (BPA, triclosan, phthalates, PCBs); (v) fertilization rate (PFCs, PCBs); (vi) implantation (BPA, phthalates, PCBs); (vii) embryo quality (triclosan, PCBs, BPA); (viii) rate of clinical pregnancy and live births (parabens, phthalates). The studies were mostly well-designed and used prospective cohorts with the exposure assessment based on the biomarker of exposure. Considering the suggested health effects, more epidemiological data is urgently needed to confirm the presented findings.

Time compression diseconomies in environmental management: the effect of assimilation on environmental performance.

Science.gov (United States)

Lannelongue, Gustavo; Gonzalez-Benito, Javier; Gonzalez-Benito, Oscar; Gonzalez-Zapatero, Carmen

2015-01-01

This research addresses the relationship between an organisation's assimilation of its environmental management system (EMS), the experience it gains through it, and its environmental performance. Assimilation here refers to the degree to which the requirements of the management standard are integrated within a plant's daily operations. Basing ourselves on the heterogeneity of organisations, we argue that assimilation and experience will inform environmental performance. Furthermore, we posit that the relationship between assimilation and environmental performance depends on experience. The attempt to obtain greater assimilation in a shorter time leads an organisation to record a poorer environmental outcome, which we shall refer to as time compression diseconomies in environmental management. We provide empirical evidence based on 154 plants pertaining to firms in Spain subject to the European Union's CO2 Emissions Trading System. Copyright © 2014 Elsevier Ltd. All rights reserved.

Eco-Efficient Process Improvement at the Early Development Stage: Identifying Environmental and Economic Process Hotspots for Synergetic Improvement Potential.

Piccinno, Fabiano; Hischier, Roland; Seeger, Stefan; Som, Claudia

2018-05-15

We present here a new eco-efficiency process-improvement method to highlight combined environmental and costs hotspots of the production process of new material at a very early development stage. Production-specific and scaled-up results for life cycle assessment (LCA) and production costs are combined in a new analysis to identify synergetic improvement potentials and trade-offs, setting goals for the eco-design of new processes. The identified hotspots and bottlenecks will help users to focus on the relevant steps for improvements from an eco-efficiency perspective and potentially reduce their associated environmental impacts and production costs. Our method is illustrated with a case study of nanocellulose. The results indicate that the production route should start with carrot pomace, use heat and solvent recovery, and deactivate the enzymes with bleach instead of heat. To further improve the process, the results show that focus should be laid on the carrier polymer, sodium alginate, and the production of the GripX coating. Overall, the method shows that the underlying LCA scale-up framework is valuable for purposes beyond conventional LCA studies and is applicable at a very early stage to provide researchers with a better understanding of their production process.

Application of existing geostatistical theory of stream networks provides a number of interesting and challenging problems. Most of statistical tools in the traditional geostatistics have been based on a Euclidean distance such as autocovariance functions, but for stream data is not permissible since it deals with a stream distance. To overcome this autocovariance developed a model based on the distance the flow with using convolution kernel approach (moving average construction). Spatial model for a stream networks is widely used to monitor environmental on a river networks. In a case study of a river in province of West Java, the objective of this paper is to analyze a capability of a predictive on two environmental variables, potential of hydrogen (PH) and temperature using ordinary kriging. Several the empirical results show: (1) The best fit of autocovariance functions for temperature and potential hydrogen (ph) of Citarik River is linear which also yields the smallest root mean squared prediction error (RMSPE), (2) the spatial correlation values between the locations on upstream and on downstream of Citarik river exhibit decreasingly

Aging in Context: Individual and Environmental Pathways to Aging-Friendly Communities-The 2015 Matthew A. Pollack Award Lecture.

Science.gov (United States)

Scharlach, Andrew E

2017-08-01

Reflecting the theme of the 2015 Gerontological Society of America (GSA) Annual Scientific Meeting, "Aging as a Lifelong Process," this paper examines intersections between aging processes and their environmental context, develops theory regarding constructive developmental processes and their environmental context, and considers potential implications for conceptualizing and creating aging-friendly communities. The first section examines the primary goals of aging-friendly communities, that is, promoting elder well-being. The second section explores the role of environmental pathways in fostering well-being throughout the lifecourse. The third section presents a new Process Model of Constructive Aging that identifies key developmental processes at the intersection of individual and environmental pathways. The final section considers potential implications for creating aging-friendly communities, including ways in which cities and towns can promote the ability of community members to live fully throughout their lives, and identifies some key conceptual and empirical challenges affecting the future of the field. © The Author 2017.

Visualizing and Understanding Socio-Environmental Dynamics in Baltimore

Science.gov (United States)

Zaitchik, B. F.; Omeara, K.; Guikema, S.; Scott, A.; Bessho, A.; Logan, T. M.

2015-12-01

The City of Baltimore, like any city, is the sum of its component neighborhoods, institutions, businesses, cultures, and, ultimately, its people. It is also an organism in its own right, with distinct geography, history, infrastructure, and environments that shape its residents even as it is shaped by them. Sometimes these interactions are obvious but often they are not; while basic economic patterns are widely documented, the distribution of socio-spatial and environmental connections often hides below the surface, as does the potential that those connections hold. Here we present results of a collaborative initiative on the geography, design, and policy of socio-environmental dynamics of Baltimore. Geospatial data derived from satellite imagery, demographic databases, social media feeds, infrastructure plans, and in situ environmental networks, among other sources, are applied to generate an interactive portrait of Baltimore City's social, health, and well-being dynamics. The layering of data serves as a platform for visualizing the interconnectedness of the City and as a database for modeling risk interactions, vulnerabilities, and strengths within and between communities. This presentation will provide an overview of project findings and highlight linkages to education and policy.

For many years, nitrogen mineral fertilization has been regarded as a most highly productive and profitable farming practice. The downside, however, is represented by the negative environmental repercussions of its use. A potential source of N is found in organic residue, which has increased dramatically due to human activity. For instance, organic debris generated in urban areas and resulting rom intensive livestock breeding. (Author)

Environmental occurrence of arsenic in Colombia: a review.

Science.gov (United States)

Alonso, David L; Latorre, Sergio; Castillo, Elianna; Brandão, Pedro F B

2014-03-01

The international literature on the presence of arsenic (As) in Latin America does not disclose the true magnitude of the presence of As in Colombia. In this paper, we summarize the literature on As occurrence in Colombia. The data reveal that As is present in matrices such as soil, sediments and water and in the food chain. Some of the As concentrations exceed the limits specified by national and international regulations. Arsenic higher concentrations are associated with mining regions (e.g., soils, up to 148 mg/kg; sediments, up to 1400 mg/kg) and agricultural areas (e.g., vegetables, up to 5.40 mg/kg; irrigation water, up to 255 μg/L), and underscore the potential human and environmental risks associated with the presence of As in the country. This review highlights the importance of focusing research on understanding the occurrence, origin and distribution of As in Colombia to better understand its environmental and public health impact.

Electric vehicles (EVs) powered by lithium-ion batteries (LIBs) or proton exchange membrane hydrogen fuel cells (PEMFCs) offer important potential climate change mitigation effects when combined with clean energy sources. The development of novel nanomaterials may bring about the next wave of technical improvements for LIBs and PEMFCs. If the next generation of EVs is to lead to not only reduced emissions during use but also environmentally sustainable production chains, the research on nanomaterials for LIBs and PEMFCs should be guided by a life-cycle perspective. In this Analysis, we describe an environmental life-cycle screening framework tailored to assess nanomaterials for electromobility. By applying this framework, we offer an early evaluation of the most promising nanomaterials for LIBs and PEMFCs and their potential contributions to the environmental sustainability of EV life cycles. Potential environmental trade-offs and gaps in nanomaterials research are identified to provide guidance for future nanomaterial developments for electromobility.

Making quick and effective decisions in environment management are based on multiple and complex parameters, a data warehouse is a powerful tool for the over all management of massive environmental information. Selecting the right data from a warehouse is an important factor consideration for end-users. This paper proposed an intelligent environmental data warehouse system. It consists of data warehouse to feed an environmental researchers and managers with desire environmental information needs to their research studies and decision in form of geometric and attribute data for study area, and a metadata for the other sources of environmental information. In addition, the proposed intelligent search engine works according to a set of rule, which enables the system to be aware of the environmental data wanted by the end-user. The system development process passes through four stages. These are data preparation, warehouse development, intelligent engine development and internet platform system development. (author)

strain, cellular and molecular targets, and relative carcinogenic potency, our animal model may offer a more realistic platform to study oral carcinogenesis. In this perspective, we also discuss our preclinical studies to demonstrate the potential of black raspberry extracts on the prevention of OSCC. Specifically, we were the first to demonstrate that black raspberry inhibited DB[a,l]P-DNA binding and of particular importance its capacity to enhance the repair of DB[a,l]P-induced bulky lesions in DNA. We believe that the information presented in this perspective will stimulate further research on the impact of environmental carcinogens in the development of oral cancer and may lead to novel strategies toward the control and prevention of this disease.

Thallium pollution in China: A geo-environmental perspective.

2012-04-01

It is well known that thallium (Tl) is a non-essential and toxic metal to human health, but less is known about the geo-environmentally-induced Tl pollution and its associated health impacts. High concentrations of Tl that are primarily associated with the epithermal metallogenesis of sulfide minerals have the potential of producing Tl pollution in the environment, which has been recognized as an emerging pollutant in China. This paper aims to review the research progress in China on Tl pollution in terms of the source, mobility, transportation pathway, and health exposure of Tl and to address the environmental concerns on Tl pollution in a geo-environmental perspective. Tl associated with the epithermal metallogenesis of sulfide minerals has been documented to disperse readily and accumulate through the geo-environmental processes of soil enrichment, water transportation and food crop growth beyond a mineralized zone. The enrichments of Tl in local soil, water, and crops may result in Tl pollution and consequent adverse health effects, e.g. chronic Tl poisoning. Investigation of the baseline Tl in the geo-environment, proper land use and health-related environmental planning and regulation are critical to prevent the Tl pollution. Examination of the human urinary Tl concentration is a quick approach to identify exposure of Tl pollution to humans. The experiences of Tl pollution in China can provide important lessons for many other regions in the world with similar geo-environmental contexts because of the high mobility and toxicity of Tl.

Karig, David K

2017-06-01

The fields of biosensing and bioremediation leverage the phenomenal array of sensing and metabolic capabilities offered by natural microbes. Synthetic biology provides tools for transforming these fields through complex integration of natural and novel biological components to achieve sophisticated sensing, regulation, and metabolic function. However, the majority of synthetic biology efforts are conducted in living cells, and concerns over releasing genetically modified organisms constitute a key barrier to environmental applications. Cell-free protein expression systems offer a path towards leveraging synthetic biology, while preventing the spread of engineered organisms in nature. Recent efforts in the areas of cell-free approaches for sensing, regulation, and metabolic pathway implementation, as well as for preserving and deploying cell-free expression components, embody key steps towards realizing the potential of cell-free systems for environmental sensing and remediation.

Environmental education evaluation: time to reflect, time for change.

Science.gov (United States)

Crohn, Kara; Birnbaum, Matthew

2010-05-01

Evaluation in environmental education is fairly nascent despite decades-long attention to its importance. In setting the context for future chapters appearing in this special issue of the Journal of Evaluation and Program Planning, attention is devoted to the political circumstances associated with retrenchment in the public sector and increased involvement of citizens in environmental issues in their regions. It further is nested in the context of potential political reforms in a stable market democracy where education is but one strategy that can be bundled with regulations and taxes/subsidies. Additional attention is directed to explaining many of the key evaluation theories--utilization-focused evaluation, evaluative capacity building, and program-theory driven evaluation. The final section of this chapter situates the subsequent chapters of this volume based on the demographic target (youth or adult) as well as connection to a particular evaluation theory.

As an integral part of our continuing research in environmental quality assessment approaches, we have developed a variety of passive integrative sampling devices widely applicable for use in defining the presence and potential impacts of a broad array of contaminants. The semipermeable membrane device has gained widespread use for sampling hydrophobic chemicals from water and air, the polar organic chemical integrative sampler is applicable for sequestering waterborne hydrophilic organic chemicals, the stabilized liquid membrane device is used to integratively sample waterborne ionic metals, and the passive integrative mercury sampler is applicable for sampling vapor phase or dissolved neutral mercury species. This suite of integrative samplers forms the basis for a new passive sampling approach for assessing the presence and potential toxicological significance of a broad spectrum of environmental contaminants. In a proof-of-concept study, three of our four passive integrative samplers were used to assess the presence of a wide variety of contaminants in the waters of a constructed wetland, and to determine the effectiveness of the constructed wetland in removing contaminants. The wetland is used for final polishing of secondary-treatment municipal wastewater and the effluent is used as a source of water for a state wildlife area. Numerous contaminants, including organochlorine pesticides, polycyclic aromatic hydrocarbons, organophosphate pesticides, and pharmaceutical chemicals (e.g., ibuprofen, oxindole, etc.) were detected in the wastewater. Herein we summarize the results of the analysis of the field-deployed samplers and demonstrate the utility of this holistic approach.

The environmental context of Acidithiobacillus ferrooxidans and its potential role as an ecosystem engineer in sulphidic mine waste

Energy Technology Data Exchange (ETDEWEB)

Ebenaa, Gustav

2001-06-01

Microorganisms are the causative agent of the environmental problems since they catalyse the weathering of the (sulphidic) waste. The chemical oxidation alone is not fast enough to create any severe environmental problems. Acidithiobacillus ferrooxidans is thought to be a key organism in weathering of sulphide minerals. A. ferrooxidans is affected by several more or less abiotic factors. The influence of temperature, pH and nutrient deficiency as potentially limiting factors for the activity of A. ferrooxidans has been investigated. It seems that temperature has less influence on its activity, but rather reflects the origin of the bacterial isolate. An alkaline pH seems enough to hinder growth and activity. The nutrients do not seem to be a limiting factor in the studied environment. The possible regulation of the activity of A. ferrooxidans is therefore a way to, at least partly, mitigate the environmental impact from mine waste. Waste from the mining industry is the largest waste problem in Sweden. With amounts over 600 million tonnes one could easily imagine the tremendous cost involved in the abatement. The MiMi-programme, with researchers from several relevant fields, has as its aim to evaluate present and to find alternative techniques to mitigate the environmental impact from mine waste. The understanding of A. ferrooxidans and its role as an ecosystem engineer is essential both in evaluating present techniques and even more so in finding alternative abatement techniques for sulphidic mine waste.

Sukhov, Vladimir; Nerush, Vladimir; Orlova, Lyubov; Vodeneev, Vladimir

2011-12-21

Action potential is considered to be one of the primary responses of a plant to action of various environmental factors. Understanding plant action potential propagation mechanisms requires experimental investigation and simulation; however, a detailed mathematical model of plant electrical signal transmission is absent. Here, the mathematical model of action potential propagation in plants has been worked out. The model is a two-dimensional system of excitable cells; each of them is electrically coupled with four neighboring ones. Ion diffusion between excitable cell apoplast areas is also taken into account. The action potential generation in a single cell has been described on the basis of our previous model. The model simulates active and passive signal transmission well enough. It has been used to analyze theoretically the influence of cell to cell electrical conductivity and H(+)-ATPase activity on the signal transmission in plants. An increase in cell to cell electrical conductivity has been shown to stimulate an increase in the length constant, the action potential propagation velocity and the temperature threshold, while the membrane potential threshold being weakly changed. The growth of H(+)-ATPase activity has been found to induce the increase of temperature and membrane potential thresholds and the reduction of the length constant and the action potential propagation velocity.

Assessing the impact of in-utero exposures: potential effects of paracetamol on male reproductive development.

Science.gov (United States)

Kilcoyne, Karen R; Mitchell, Rod T

2017-12-01

Human male reproductive disorders (cryptorchidism, hypospadias, testicular cancer and low sperm counts) are common and some may be increasing in incidence worldwide. These associated disorders can arise from subnormal testosterone production during fetal life. This has resulted in a focus on in-utero environmental influences that may result in reproductive effects on the offspring in later life. Over recent years, there has been a dramatic increase in the scientific literature describing associations between in-utero environmental exposures (eg, industrial chemicals and pharmaceuticals) and subsequent reproductive outcomes in male offspring. This includes studies investigating a potential role for in-utero analgesic exposure(s) on the fetal testis; however, providing definitive evidence of such effects presents numerous challenges. In this review, we describe an approach to assessing the potential clinical relevance of in-utero (and postnatal) environmental exposures on subsequent male reproductive function using exposure to the analgesic paracetamol as an example. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Environmental change challenges decision-making during post-market environmental monitoring of transgenic crops.

Science.gov (United States)

Sanvido, Olivier; Romeis, Jörg; Bigler, Franz

2011-12-01

The ability to decide what kind of environmental changes observed during post-market environmental monitoring of genetically modified (GM) crops represent environmental harm is an essential part of most legal frameworks regulating the commercial release of GM crops into the environment. Among others, such decisions are necessary to initiate remedial measures or to sustain claims of redress linked to environmental liability. Given that consensus on criteria to evaluate 'environmental harm' has not yet been found, there are a number of challenges for risk managers when interpreting GM crop monitoring data for environmental decision-making. In the present paper, we argue that the challenges in decision-making have four main causes. The first three causes relate to scientific data collection and analysis, which have methodological limits. The forth cause concerns scientific data evaluation, which is controversial among the different stakeholders involved in the debate on potential impacts of GM crops on the environment. This results in controversy how the effects of GM crops should be valued and what constitutes environmental harm. This controversy may influence decision-making about triggering corrective actions by regulators. We analyse all four challenges and propose potential strategies for addressing them. We conclude that environmental monitoring has its limits in reducing uncertainties remaining from the environmental risk assessment prior to market approval. We argue that remaining uncertainties related to adverse environmental effects of GM crops would probably be assessed in a more efficient and rigorous way during pre-market risk assessment. Risk managers should acknowledge the limits of environmental monitoring programmes as a tool for decision-making.

The Federal Environment Agency (UBA) in Germany as one Competent Authority of the European Member States involved with the assessment and authorisation of chemicals, pesticides, biozides and medicals, has a wide expertise of complex information systems. Having timely, comprehensive and reliable information on the environmental relevant properties (e.g. of chemical substances and preparations) is of immense importance for all sections dealing with environmental protection issues. Regarding the reality of available information systems in each environmental section, and moreover in each section itself, there has been developed several specific approaches to gather, store and search its relevant data. This makes sense due to each section has its own requirements, different user groups (industry and authorities or just authorities or scientific partners etc.), different budgets to bring technology 'on the road', and different (legally obligatory) procedures to handle the data and information of such systems. Nevertheless, there several strong reasons to look for a Linked Environmental Data infrastructure - at least internally in one authority itself: - Overcome the mostly separated systems; - Explore the potential of data silos in several environmental sections; - Efficiency/effectiveness in data gathering, assessment, results, budgets..; - sharing of knowledge, i.e. use of specific prepared information of specially intended information systems; - timelyness of data/information; - best data/information from most competent partner/section; - gain from already available systems and their data/information; - speed up developments and availability of data/information. Of course there are also several points which might be a huge obstacle to Linked Environmental Data (LED), e.g. confidential business data. This leads already to the distinction between 'Open LED' and 'Non-Open LED'. Nevertheless, the potential benefits and the possibilities

An environmental friendly electrode and extended cathodic potential window for anodic stripping voltammetry of zinc detection

2016-01-01

This work reports on a novel polyeriochrome black T (poly(EBT) modified electrode for use as an environmentally-friendly electrode material that extends the cathodic potential window and improves the sensitivity and repeatability to detect zinc in industrial wastewater. The poly(EBT) film on the GCE surface was fabricated by electropolymerization. The surface morphology and electrochemical behavior of the modified electrode were characterized by scanning electron microscopy, fourier transform infrared spectroscopy and anodic stripping voltammetry. Under optimal conditions, the poly(EBT)/GCE exhibited a high hydrogen overvoltage (extended cathodic potential window). It provided a high sensitivity, a wide linear range (1.0 to 400.0 μg L −1 ), a low detection limit (0.9 μg L −1 ), had excellent repeatability and good recoveries (95% to 105%). This proposed modified electrode was applied to the determination of zinc in wastewater samples, and the results were consistent with those of an inductively coupled plasma atomic emission spectroscopy analysis.

2015-01-01

Exfoliated transition metal dichalcogenides (TMDs) such as WS2 and MoS2 have shown exciting potential for energy storage, catalysis and optoelectronics. So far, solution based methods for scalable production of few-layer TMDs usually involve the use of organic solvents or dangerous chemicals. Here, we report an eco-friendly method for facile synthesis of few-layer WS2 and MoS2 nanosheets using dilute aqueous solution of household detergent. Short time sonication of varying amount of bulk samples in soapy water was used to scale up the production of nanosheets. Thermal stability, optical absorption and Raman spectra of as-synthesized WS2 and MoS2 nanosheets are in close agreement with those from other synthesis techniques. Efficient photocatalytic activity of TMDs nanosheets was demonstrated by decomposing Brilliant Green dye in aqueous solution under visible light irradiation. Our study shows the great potential of TMDs nanosheets for environmental remediation by degrading toxic industrial chemicals in wastewater using sunlight. PMID:26503125

Environmental risk analysis of oil handling facilities in port areas. Application to Tarragona harbor (NE Spain).

Science.gov (United States)

Valdor, Paloma F; Gómez, Aina G; Puente, Araceli

2015-01-15

Diffuse pollution from oil spills is a widespread problem in port areas (as a result of fuel supply, navigation and loading/unloading activities). This article presents a method to assess the environmental risk of oil handling facilities in port areas. The method is based on (i) identification of environmental hazards, (ii) characterization of meteorological and oceanographic conditions, (iii) characterization of environmental risk scenarios, and (iv) assessment of environmental risk. The procedure has been tested by application to the Tarragona harbor. The results show that the method is capable of representing (i) specific local pollution cases (i.e., discriminating between products and quantities released by a discharge source), (ii) oceanographic and meteorological conditions (selecting a representative subset data), and (iii) potentially affected areas in probabilistic terms. Accordingly, it can inform the design of monitoring plans to study and control the environmental impact of these facilities, as well as the design of contingency plans. Copyright © 2014 Elsevier Ltd.

Sending the Right Bill to the Right People: Climate change, environmental degradation, and social vulnerabilities in Central Vietnam

Bruun, Ole

2012-01-01

In a range of international reports Vietnam is pointed out as among the 5 to 10 most climate-vulnerable countries, which are taking center stage in global climate change assistance and thus attracting huge amounts of foreign aid for research, mitigation, adaptation, disaster management, etc....... However, for various reasons relating to global and domestic politics, climate change adaptation and mitigation in Vietnam are separating from general environmental management, while at the same time failing to address social inequality. From a global justice perspective this may seem irrelevant but when...... the resulting technocratic approaches are applied to aid programs, addressing climate change as an autonomous field, the problems on the ground become distorted. Based on field studies in central Vietnam, the paper argues that fragmented approaches risk missing the target of helping the most vulnerable...

Potential environmental drivers of a regional blue mussel mass mortality event (winter of 2014, Breton Sound, France)

In the context of global change, increasing mariculture production has raised particular concerns regarding its environmental impact and sustainability. Molluscs and particularly blue mussel account for a significant part of this total production. Although blue mussels are considered to be pretty resilient to environmental disturbances, we report in this study an unprecedented mussel mortality event that occurred during the winter of 2014 in the Breton Sound. 9000 metric tonnes of mussels were lost and mortality rates up to 100% were recorded at some farming areas. Through a coupling approach, the present work aims to better understand the potential environmental drivers associated with those mortalities. Firstly, we analysed long-term in situ and satellite data from environmental monitoring networks (available since 1998) to characterize the variability of seawater masses of the sound during the winter of 2014. Secondly, we used modelling simulations to study the possible relationship between seawater hydrodynamics and observed spatio-temporal patterns of mussel mortalities. From January to April 2014 at the long-line culture site where mortalities started, seawater temperatures ranged from 8.3 to 13.3 °C (10.2 ± 0.8 °C). Salinity and turbidity values showed successive and short drops (below 16; 29.3 ± 2.3) and numerous peaks (above 70 NTU; 17.4 ± 13.4 NTU) respectively. Winter conditions of 2014 were encountered along the entire French Atlantic coastline and linked to the sixth highest positive North Atlantic Oscillation (NAO +) index recorded since 1865. These particular environmental variations characterized the winter of 2014 but also others whereas no comparable mussel mortality rates were reported. Exact causes of the 2014 mortality event are still unknown but we showed these environmental variations could not alone be responsible. These have likely affected the sensitivity of the blue mussel populations that were already weakened by early spawning

Substituting computers for services - potential to reduce ICT's environmental footprint

Energy Technology Data Exchange (ETDEWEB)

Plepys, A. [The International Inst. for Industrial Environmental Economics at Lund Univ. (Sweden)

2004-07-01

The environmental footprint of IT products are significant and, in spite of manufacturing and product design improvements, growing consumption of electronics results in increasing absolute environmental impact. Computers have short technological lifespan and a lot of the in-build performance, although necessary, remains idling for most of the time. Today, most of computers used in non-residential sectors are connected to networks. The premise of this paper is that computer networks are an untapped resource, which could allow addressing environmental impacts of IT products through centralising and sharing computing resources. The article presents results of a comparative study of two computing architectures. The first one is the traditional decentralised PC-based system and the second - centralised server-based computing (SBC) system. Both systems deliver equivalent functions to the final users and this can be compared on a one-to-one basis. The study evaluates product lifespan, energy consumption in user stage, product design and its environmental implications in manufacturing. (orig.)

Here, we propose an approach to environmental flow assessment that considers spatial pattern variations in potential habitats affected by river discharges and tidal currents in estuaries. The approach comprises four steps: identifying and simulating the distributions of critical environmental factors for habitats of typical species in an estuary; mapping of suitable habitats based on spatial distributions of the Habitat Suitability Index (HSI) and adopting the habitat aggregation index to understand fragmentation of potential suitable habitats; defining variations in water requirements for a certain species using trade-off analysis for different protection objectives; and recommending environmental flows in the estuary considering the compatibility and conflict of freshwater requirements for different species. This approach was tested using a case study in the Yellow River Estuary. Recommended environmental flows were determined by incorporating the requirements of four types of species into the assessments. Greater variability in freshwater inflows could be incorporated into the recommended environmental flows considering the adaptation of potential suitable habitats with variations in the flow regime. Environmental flow allocations should be conducted in conjunction with land use conflict management in estuaries. Based on the results presented here, the proposed approach offers flexible assessment of environmental flow for aquatic ecosystems that may be subject to future change.

In recent years a large and growing body of research has greatly advanced our understanding of primary progressive apraxia of speech. Handedness has emerged as one potential marker of selective vulnerability in degenerative diseases. This study evaluated the clinical and imaging findings in non-right handed compared to right handed participants in a prospective cohort diagnosed with primary progressive apraxia of speech. A total of 30 participants were included. Compared to the expected rate in the population, there was a higher prevalence of non-right handedness among those with primary progressive apraxia of speech (6/30, 20%). Small group numbers meant that these results did not reach statistical significance, although the effect sizes were moderate-to-large. There were no clinical differences between right handed and non-right handed participants. Bilateral hypometabolism was seen in primary progressive apraxia of speech compared to controls, with non-right handed participants showing more right hemispheric involvement. This is the first report of a higher rate of non-right handedness in participants with isolated apraxia of speech, which may point to an increased vulnerability for developing this disorder among non-right handed participants. This challenges prior hypotheses about a relative protective effect of non-right handedness for tau-related neurodegeneration. We discuss potential avenues for future research to investigate the relationship between handedness and motor disorders more generally. Copyright © 2018 Elsevier B.V. All rights reserved.

Geothermal energy from the earth: Its potential impact as an environmentally sustainable resource

International Nuclear Information System (INIS)

Mock, J.E.; Tester, J.W.; Wright, P.M.

1997-01-01

Geothermal energy technology is reviewed in terms of its current impact and future potential as an energy source. In general, the geothermal energy resource base is large and well distributed globally. Geothermal systems have a number of positive social characteristics (they are simple, safe, and adaptable systems with modular 1--50 MW [thermal (t) or electric (e)] plants capable of providing continuous baseload, load following, or peaking capacity) and benign environmental attributes (negligible emissions of CO 2 , SO x , NO x , and particulates, and modest land and water use). Because these features are compatible with sustainable growth of global energy supplies in both developed and developing countries, geothermal energy is an attractive option to replace fossil and fissile fuels. In 1997, about 7,000 MWe of base-load generating capacity and over 15,000 MWt of heating capacity from high-grade geothermal resources are in commercial use worldwide. 114 refs., 6 figs., 4 tabs

Environmental politics in the 1990s: The tension between liberalism and environmental quality

International Nuclear Information System (INIS)

Cahn, M.A.

1991-01-01

There are two structural tensions between liberalism and environmental quality. First, liberalism's emphasis on individual self-interest creates a problematic concept of communal good. Society, as manifest in liberal contract theory, exists not to find some higher good, but to protect individual rights. Individual and corporate property rights have consistently overshadowed community claims on resource management. Second, capitalism has been characterized by a constant drive for expansion in search of increased productivity and profit. The impact of that expansionary ethic has been overuse of limited resources and the poisoning of the physical environment. This study combines normative theory with case studies of the substantive policy areas of air, water, and waste. Environmental policy's analyzed with attention to the parameters of American political culture and the inherent limitations the language of liberalism places on policy choices. The literature on symbolic policy is then applied exploring the role of symbolic politics in easing the tension between liberalism and environmental quality. Ultimately, substantive policy areas are explored in a effort to explain the evolution of specific policies

2012-01-01

Community-engaged research on environmental problems has reshaped researcher-participant relationships, academic-community interaction, and the role of community partners in human subjects protection and ethical oversight. We draw on our own and others’ research collaborations with environmental health and justice social movement organizations to discuss the ethical concerns that emerge in community-engaged research. In this paper we introduce the concept of reflexive research ethics: ethical guidelines and decision-making principles that depend on continual reflexivity concerning the relationships between researchers and participants. Seeing ethics in this way can help scientists conduct research that simultaneously achieves a high level of professional conduct and protects the rights, well-being, and autonomy of both researchers and the multiple publics affected by research. We highlight our research with community-based organizations in Massachusetts, California, and Alaska, and discuss the potential impacts of the community or social movement on the research process and the potential impacts of research on community or social movement goals. We conclude by discussing ways in which the ethical concerns that surface in community-engaged research have led to advances in ethical research practices. This type of work raises ethical questions whose answers are broadly relevant for social movement, environmental, and public health scholars. PMID:22690133

Protection of civil rights and technological development

Wagner, H.

1985-01-01

The question of how the consequences of technological development are to be mastered on the legal level is not primarily a problem of the administrative procedure. The essential point in the discussion on protection of basic rights is not to be seen in the citizen's right to participate in administrative procedures, but rather in the substantive civil rights of individual persons as against the government, together with the system of values established in the Basic Law and derived from the basic rights, as well as in the proper functioning of the principle of separation of powers (legislature, administration, and judicature). The law on procedure and thus the idea of (protection of civil rights by rules of procedure) in this context only have an enhancing effect. Practical protection of civil rights is also ascertained in the Federal Republic of Germany by the particularly well-established guarantee of access to the courts. Another idea to be mentioned in this context is an approach that can be termed as 'protection of civil rights by government-funded research'. Other facts contributing to building a protective shield against infringement of civil rights by technology, activities or installations, include e.g. the federal structure of the state and the administration, type and scope of organisation of the public service, the established system of environmental protection and the safety provided by the current system of expert opinions.

Environmental aspects of nuclear power

International Nuclear Information System (INIS)

Ward, D.P.

1987-01-01

Nuclear power provides the world with an important option for generating electricity. To successfully and safely utilize this power, engineering and environmental factors should be carefully considered throughout a nuclear power plant project, especially during the planning stages. This paper discusses the major environmental aspects of a nuclear power plant project from site selection to retirement. During the site selection process, both engineering and environmental resources must be identified and evaluated. Environmental resources include areas that support agricultural or aquatic commercial activities, habitats for commercial or endangered species, population centers, transportation systems, and recreational areas. Also, during the site selection process, the potential impacts of both construction and operating activities must be considered. In addition to the area actually disturbed by construction, construction activities also affect local services, such as transportation systems, housing, school systems, and other social services. Since nuclear power plants use a 'clean fuel,' generally the most significant operating activity having a potential environmental impact is the discharge of cooling water. The potential effect of this discharge on commercial activities and sensitive habitats should be thoroughly evaluated. Lastly, the method of decommissioning can affect long-range land use planning and should therefore be considered during the planning process. With appropriate planning, nuclear power plants can be constructed and operated with minimum environmental impact. (author)

Global warming and environmental contaminants in aquatic organisms: the need of the etho-toxicology approach.

Science.gov (United States)

Manciocco, Arianna; Calamandrei, Gemma; Alleva, Enrico

2014-04-01

Environmental contaminants are associated with a wide spectrum of pathological effects. Temperature increase affects ambient distribution and toxicity of these chemicals in the water environment, representing a potentially emerging problem for aquatic species with short-, medium- and long-term repercussions on human health through the food chain. We assessed peer-reviewed literature, including primary studies, review articles and organizational reports available. We focused on studies concerning toxicity of environmental pollutants within a global warming scenario. Existing knowledge on the effects that the increase of water temperature in a contaminated situation has on physiological mechanisms of aquatic organisms is presented. Altogether we consider the potential consequences for the human beings due to fish and shellfish consumption. Finally, we propose an etho-toxicological approach to study the effects of toxicants in conditions of thermal increase, using aquatic organisms as experimental models under laboratory controlled conditions.

Potential of low-temperature anaerobic digestion to address current environmental concerns on swine production.

Science.gov (United States)

Massé, D I; Masse, L; Xia, Y; Gilbert, Y

2010-04-01

Environmental issues associated with swine production are becoming a major concern among the general public and are thus an important challenge for the swine industry. There is now a renewed interest in environmental biotechnologies that can minimize the impact of swine production and add value to livestock by-products. An anaerobic biotechnology called psychrophilic anaerobic digestion (PAD) in sequencing batch reactors (SBR) has been developed at Agriculture and Agri-Food Canada. This very stable biotechnology recovers usable energy, stabilizes and deodorizes manure, and increases the availability of plant nutrients. Experimental results indicated that PAD of swine manure slurry at 15 to 25 degrees C in intermittently fed SBR reduces the pollution potential of manure by removing up to 90% of the soluble chemical oxygen demand. The process performs well under intermittent feeding, once to 3 times a week, and without external mixing. Bioreactor feeding activities can thus be easily integrated into the routine manure removal procedures in the barn, with minimal interference with other farm operations and use of existing manure-handling equipment. Process stability was not affected by the presence of antibiotics in manure. The PAD process was efficient in eliminating populations of zoonotic pathogens and parasites present in raw livestock manure slurries. Psychrophilic anaerobic digestion in SBR could also be used for swine mortality disposal. The addition of swine carcasses, at loading rates representing up to 8 times the normal mortality rates on commercial farms, did not affect the stability of SBR. No operational problems were related to the formation of foam and scum. The biotechnology was successfully operated at semi-industrial and full commercial scales. Biogas production rate exceeded 0.20 L of methane per gram of total chemical oxygen demand fed to the SBR. The biogas was of excellent quality, with a methane concentration ranging from 70 to 80%.

Incorporating environmental justice into environmental decision making

Energy Technology Data Exchange (ETDEWEB)

Wolfe, A.K.; Vogt, D.P.; Hwang, Ho-Ling [Oak Ridge National Lab., TN (United States)] [and others

1995-07-01

Executive Order 12898, signed on February 11, 1994, broadly states that federal activities, programs, and policies should not produce disproportionately high and adverse impacts on minority and low-income populations. Moreover, the Order indicates that these populations should not be denied the benefits of, or excluded from participation in, these activities, programs, and policies. Because a presidential memorandum accompanying the order said that National Environmental Policy Act (NEPA) documents should begin to address environmental justice immediately, much attention has been paid to assessment-related issues. Also important, a topic that appears to have received relatively little attention, is how decision makers should be expected to use information about environmental justice in their decision making. This paper discusses issues surrounding the use of environmental justice information in the decision-making process by focusing on the following five main topics: (1) the importance, or weight, attached to environmental justice within larger decision-making contexts; (2) the potential tension between localized environmental justice issues and regional or national issues and needs; (3) the use of environmental justice information to develop (perhaps in concert with affected minority and low-income communities) appropriate mitigation strategies, or to establish conditions under which activities, programs, and policies may be accepted locally; (4) the general implications of shifting the distribution of broadly defined risks, costs, and benefits among different population groups; and (5) the implications of implementing environmental justice on an individual, ad hoc basis rather than within a larger environmental justice framework. This paper raises the issues and discusses the implications of alternative approaches to them.

Theoretical foundations of shareholders' right to appraisal

Full Text Available Shareholders' right to appraisal represents a controversial topic of corporation law, which is why a relatively small number of countries accept it. In this article, the authors analyze the goals that are supposed to be achieved with the introduction of shareholders' appraisal rights. In this respect, traditional and modern explanations for the introduction or maintaining of this right have been presented. In the second part of this article, shareholders' right to appraisal has been critically examined, mostly from corporations' perspective. Afterwards, several potential causes of inefficiency of using this right have been identified. Perceiving pros and cons of shareholders' right to appraisal is of particular importance for Serbia, in order to draw a conclusion about harmonization of our legislative solutions with the theoretical foundations of this right.

Occupational and environmental lung disease remains a major cause of respiratory impairment worldwide. Despite regulations, increasing rates of coal worker's pneumoconiosis and progressive massive fibrosis are being reported in the United States. Dust exposures are occurring in new industries, for instance, silica in hydraulic fracking. Nonoccupational environmental lung disease contributes to major respiratory disease, asthma, and COPD. Knowledge of the imaging patterns of occupational and environmental lung disease is critical in diagnosing patients with occult exposures and managing patients with suspected or known exposures.

Nanoparticles: Their potential toxicity, waste and environmental management

International Nuclear Information System (INIS)

Bystrzejewska-Piotrowska, Grazyna; Golimowski, Jerzy; Urban, Pawel L.

2009-01-01

This literature review discusses specific issues related to handling of waste containing nanomaterials. The aims are (1) to highlight problems related to uncontrolled release of nanoparticles to the environment through waste disposal, and (2) to introduce the topics of nanowaste and nanotoxicology to the waste management community. Many nanoparticles used by industry contain heavy metals, thus toxicity and bioaccumulation of heavy metals contained in nanoparticles may become important environmental issues. Although bioavailability of heavy metals contained in nanoparticles can be lower than those present in soluble form, the toxicity resulting from their intrinsic nature (e.g. their size, shape or density) may be significant. An approach to the treatment of nanowaste requires understanding of all its properties - not only chemical, but also physical and biological. Progress in nanowaste management also requires studies of the environmental impact of the new materials. The authors believe Amara's law is applicable to the impact of nanotechnologies, and society might overestimate the short-term effects of these technologies, while underestimating the long-term effects. It is necessary to have basic information from companies about the level and nature of nanomaterials produced or emitted and about the expectation of the life cycle time of nanoproducts as a basis to estimate the level of nanowaste in the future. Without knowing how companies plan to use and store recycled and nonrecycled nanomaterials, development of regulations is difficult. Tagging of nanoproducts is proposed as a means to facilitate separation and recovery of nanomaterials.

Characterization and assessment of potential environmental risk of tailings stored in seven impoundments in the Aries river basin, Western Romania

2013-01-01

Background The objective of this study was to examine the potential environmental risk of tailings resulted after precious and base metal ores processing, stored in seven impoundments located in the Aries river basin, Romania. The tailings were characterized by mineralogical and elemental composition, contamination indices, acid rock drainage generation potential and water leachability of hazardous/priority hazardous metals and ions. Multivariate statistical methods were used for data interpretation. Results Tailings were found to be highly contaminated with several hazardous/priority hazardous metals (As, Cu, Cd, Pb), and pose potential contamination risk for soil, sediments, surface and groundwater. Two out of the seven studied impoundments does not satisfy the criteria required for inert wastes, shows acid rock drainage potential and thus can contaminate the surface and groundwater. Three impoundments were found to be highly contaminated with As, Pb and Cd, two with As and other two with Cu. The tailings impoundments were grouped based on the enrichment factor, geoaccumulation index, contamination factor and contamination degree of 7 hazardous/priority hazardous metals (As, Cd, Cr, Cu, Ni, Pb, Zn) considered typical for the studied tailings. Principal component analysis showed that 47% of the elemental variability was attributable to alkaline silicate rocks, 31% to acidic S-containing minerals, 12% to carbonate minerals and 5% to biogenic elements. Leachability of metals and ions was ascribed in proportion of 61% to silicates, 11% to acidic minerals and 6% to the organic matter. A variability of 18% was attributed to leachability of biogenic elements (Na, K, Cl-, NO3-) with no potential environmental risk. Pattern recognition by agglomerative hierarchical clustering emphasized the grouping of impoundments in agreement with their contamination degree and acid rock drainage generation potential. Conclusions Tailings stored in the studied impoundments were found to

Valenzuela, Patricia M; Matus, M Soledad; Araya, Gabriela I; Paris, Enrique

2011-01-01

To review the most relevant articles regarding environmental pediatrics, its potential effects on health, and especially its advances in prevention. A literature search was conducted using MEDLINE/PubMed and SciELO databases. Articles from 1990 to 2010 were reviewed, in addition to book chapters related to environmental pediatrics. There is a significant variety of factors that make children highly vulnerable to environmental hazard exposure, which are mainly associated with children's comparatively greater consumption of water, food, and air in relation to body weight. According to the World Health Organization, every year more than 3 million children under the age of 5 die because of environment-related conditions. Approximately 30 to 40% of pediatric diseases are related to environmental factors. Children are constantly exposed to various environmental health hazards, among which the following stand out: contaminated water, lack of adequate sanitation facilities, air pollution, disease vectors, chemical hazards, injuries, and accidents. Nowadays, pediatricians are challenged to address environmental pediatrics health care needs. The pediatric health history needs to be more comprehensive by adding pointed questions to help identify potential environmental risks. Awareness and understanding of the noxious effects of various environmental conditions and knowledge of the related prevention measures will result in timely and adequate interventions that will improve our children's health and development.
