    Presently, all the organizations involved with nuclear activities must be one step ahead of what happens in the specific activity areas in order to avoid surprises, to guarantee their activity continuity and the objective extents, and taking into account the external environment influence exercised by the organization on their activities. So, it is necessary a continuous follow up of their transformations. This paper aims to structure a model of the environmental monitoring system oriented to the strategic planning of the Brazilian Nuclear Energy Commission, as function of that new informational needs viewing the fulfilment of that observed gap.

    Full Text Available This presentation gives a general overview of the project titled Environmental Health Indicators, coordinated by WHO and managed by the Research Centre on the Toxic Oil Syndrome and Rare Diseases in Spain. The presentations describes the objectives of the project, the steps taken and the results obtained during the feasibility study. The project aims to develop an environmental health information system that will allow the monitoring of public health and its health determinants and make international comparisons, develop environmental policies and facilitate communication with citizens. WHO developed a methodology for the development of these indicators within the conceptual framework of DPSEEA (Driving Force, Pressure, State, Exposure, Effect, Action and selected a total of 55 indicators (which included 168 variables in 10 environmental health areas. The feasibility study predicted the successful gathering of 89% of the indicators. However, data recollection proved difficult due to the frequent incompatibility of some variables in the Spanish information systems with the WHO defined variables. On a management level, the greatest difficulty arose from the disperse distribution of responsibilities in environmental health matters. In addition to the technical contribution of this project to Environmental Health in Spain, an added value has been to establish a close collaboration with the different Ministries involved.Esta ponencia presenta una visión general del proyecto de Indicadores de Salud Ambiental, coordinado por la OMS a nivel internacional y liderado por el Centro de Investigación sobre el Síndrome del Aceite Tóxico y Enfermedades Raras (CISATER en España. En ella se describen los objetivos del proyecto, las gestiones realizadas y los resultados obtenidos durante la fase de viabilidad de este proyecto. El proyecto consiste en el establecimiento de un sistema de información sobre salud ambiental que permita desarrollar una vigilancia

    Environmental scanning electron microscopy (ESEM) (1) is an imaging technique which allows hydrated, insulating samples to be imaged under an electron beam. The resolution afforded by this technique is higher than conventional optical microscopy but lower than conventional scanning electron microscopy (CSEM). The major advantage of the technique is the minimal sample preparation needed, making ESEM quick to use and the images less susceptible to the artifacts that the extensive sample preparation usually required for CSEM may introduce. Careful manipulation of both the humidity in the microscope chamber and the beam energy are nevertheless essential to prevent dehydration and beam damage artifacts. In some circumstances it is possible to image live cells in the ESEM (2).In the following sections we introduce the fundamental principles of ESEM imaging before presenting imaging protocols for plant epidermis, mammalian cells, and bacteria. In the first two cases samples are imaged using the secondary electron (topographic) signal, whereas a transmission technique is employed to image bacteria.

    Heterogeneous ice nucleation is one of the processes of critical relevance to a range of topics in the fundamental and the applied science and technologies. Heterogeneous ice nucleation initiated by particles proceeds where microscopic properties of particle surfaces essentially control nucleation mechanisms. Ice nucleation in the atmosphere on particles governs the formation of ice and mixed phase clouds, which in turn influence the Earth's radiative budget and climate. Heterogeneous ice nucleation is still insufficiently understood and poses significant challenges in predictive understanding of climate change. We present a novel microscopy platform allowing observation of individual ice nucleation events at temperature range of 193-273 K and relative humidity relevant for ice formation in the atmospheric clouds. The approach utilizes a home built novel ice nucleation cell interfaced with Environmental Scanning Electron Microscope (IN-ESEM system). The IN-ESEM system is applied for direct observation of individual ice formation events, determining ice nucleation mechanisms, freezing temperatures, and relative humidity onsets. Reported microanalysis of the ice nucleating particles (INP) include elemental composition detected by the energy dispersed analysis of X-rays (EDX), and advanced speciation of the organic content in particles using scanning transmission x-ray microscopy with near edge X-ray absorption fine structure spectroscopy (STXM/NEXAFS). The performance of the IN-ESEM system is validated through a set of experiments with kaolinite particles with known ice nucleation propensity. We demonstrate an application of the IN-ESEM system to identify and characterize individual INP within a complex mixture of ambient particles.

    Scanning electron microscopy (SEM) for observing samples at ambient atmospheric pressure is introduced in this study. An additional specimen chamber with a small window is inserted in the main specimen chamber, and the window is separated with a thin membrane or diaphragm allowing electron beam propagation. Close proximity of the sample to the membrane enables the detection of back-scattered electrons sufficient for imaging. In addition to the empirical imaging data, a probability analysis of the un-scattered fraction of the incident electron beam further supports the feasibility of atmospheric SEM imaging over a controlled membrane-sample distance.

  10. Environmental scanning as information seeking and organizational learning

    Directory of Open Access Journals (Sweden)

    2001-01-01

    Full Text Available Environmental scanning is the acquisition and use of information about events, trends, and relationships in an organization's external environment, the knowledge of which would assist management in planning the organization's future course of action. Depending on the organization's beliefs about environmental analyzability and the extent that it intrudes into the environment to understand it, four modes of scanning may be differentiated: undirected viewing, conditioned viewing, enacting, and searching. We analyze each mode of scanning by examining its characteristic information needs, information seeking, and information use behaviours. In addition, we analyze organizational learning processes by considering the sensemaking, knowledge creating and decision making processes at work in each mode.

  11. Harvesting Ambient Environmental Energy for Wireless Sensor Networks: A Survey

    2014-01-01

    Full Text Available In recent years, wireless sensor networks (WSNs have grown dramatically and made a great progress in many applications. But having limited life, batteries, as the power sources of wireless sensor nodes, have restricted the development and application of WSNs which often requires a very long lifespan for better performance. In order to make the WSNs prevalent in our lives, an alternative energy source is required. Environmental energy is an attractive power source, and it provides an approach to make the sensor nodes self-powered with the possibility of an almost infinite lifetime. The goal of this survey is to present a comprehensive review of the recent literature on the various possible energy harvesting technologies from ambient environment for WSNs.

    Scanning electron microscopy (SEM) of nanoscale objects in dry and fully hydrated conditions at different temperatures is of critical importance in revealing details of their interactions with an ambient environment. Currently available WETSEM capsules are equipped with thin electron-transparent membranes and allow imaging of samples at atmospheric pressure, but do not provide temperature control over the sample. Here, we developed and tested a thermoelectric cooling/heating setup for WETSEM capsules to allow ambient pressure in situ SEM studies with a temperature range between -15 and 100°C in gaseous, liquid, and frozen conditions. The design of the setup also allows for correlation of the SEM with optical microscopy and spectroscopy. As a demonstration of the possibilities of the developed approach, we performed real-time in situ microscopy studies of water condensation on a surface of Morpho sulkowskyi butterfly wing scales. We observed that initial water nucleation takes place on top of the scale ridges. These results confirmed earlier discovery of a preexisting polarity gradient of the ridges of Morpho butterflies. Our developed thermoelectric cooling/heating setup for environmental capsules meets the diverse needs for in situ nanocharacterization in material science, catalysis, microelectronics, chemistry, and biology.

    2015-04-01

    Identifying inequalities in air pollution levels across population groups can help address environmental justice concerns. We were interested in assessing these inequalities across major urban areas in Australia. We used a land-use regression model to predict ambient nitrogen dioxide (NO2) levels and sought the best socio-economic and population predictor variables. We used a generalised least squares model that accounted for spatial correlation in NO2 levels to examine the associations between the variables. We found that the best model included the index of economic resources (IER) score as a non-linear variable and the percentage of non-Indigenous persons as a linear variable. NO2 levels decreased with increasing IER scores (higher scores indicate less disadvantage) in almost all major urban areas, and NO2 also decreased slightly as the percentage of non-Indigenous persons increased. However, the magnitude of differences in NO2 levels was small and may not translate into substantive differences in health.

    Full Text Available This paper identifies and analyses the factors internal to the organization, which affect the activity of environmental scanning, understood here as the information seeking activity of managers, directed at the company's external environment. These factors include individual factors, such as information consciousness and exposure to information, and organizational factors such as information climate and "outwardness". The main relationships among them are also analysed. These factors were identified in the course of research aiming to provide a comprehensive understanding of the environmental scanning process (Correia & Wilson, 1996. The methodology used - a case-study approach coupled with the grounded theory method of qualitative analysis - was of major importance in obtaining information that is grounded largely on the personal experience of managers.

    2014-03-01

    Full Text Available This paper proposes the use of an autonomous assistant mobile robot in order to monitor the environmental conditions of a large indoor area and develop an ambient intelligence application. The mobile robot uses single high performance embedded sensors in order to collect and geo-reference environmental information such as ambient temperature, air velocity and orientation and gas concentration. The data collected with the assistant mobile robot is analyzed in order to detect unusual measurements or discrepancies and develop focused corrective ambient actions. This paper shows an example of the measurements performed in a research facility which have enabled the detection and location of an uncomfortable temperature profile inside an office of the research facility. The ambient intelligent application has been developed by performing some localized ambient measurements that have been analyzed in order to propose some ambient actuations to correct the uncomfortable temperature profile.

    Mud formed from environmental dust particles in humid ambient air significantly influences the performance of solar harvesting devices. This study examines the characterization of environmental dust particles and the chemo-mechanics of dry mud formed from dust particles. Analytical tools, including scanning electron microscopy, atomic force microscopy, energy dispersive spectroscopy, particle sizing, and X-ray diffraction, are used to characterize dry mud and dust particles. A micro/nano tribometer is used to measure the tangential force and friction coefficient while tensile tests are carried out to assess the binding forces of dry mud pellets. After dry mud is removed, mud residuals on the glass surface are examined and the optical transmittance of the glass is measured. Dust particles include alkaline compounds, which dissolve in water condensate and form a mud solution with high pH (pH = 7.5). The mud solution forms a thin liquid film at the interface of dust particles and surface. Crystals form as the mud solution dries, thus, increasing the adhesion work required to remove dry mud from the surface. Optical transmittance of the glass is reduced after dry mud is removed due to the dry mud residue on the surface.

    Most government agencies have some form of environmental scanning, but few have dedicated departments or full-time staff responsible for analysis. The level of ambition varies greatly from one organisation to another, and in several cases activities are delegated to personnel without sufficient experience in the field. Consultants have been important in helping to start the activities, and most agencies have hired them. We note that environment scanning/analysis is more formally organised when authorities’ core operations include societal risks and threats, or have analytical purposes. When core activities relate to national issues or a limited sector, environment scanning tends to be more informal. But it also seems to be an activity that is constantly changing. The difficulties in institutionalising these functions, along with a lack of willingness to do so, have proved to be significant.

    The exploration of remote planetary surfaces calls for the advancement of low power, highly-miniaturized instrumentation. Instruments of this nature that are capable of multiple types of analyses will prove to be particularly useful as we prepare for human return to the moon, and as we continue to explore increasingly remote locations in our Solar System. To this end, our group has been developing a miniaturized Environmental-Scanning Electron Microscope (mESEM) capable of remote investigations of mineralogical samples through in-situ topographical and chemical analysis on a fine scale. The functioning of an SEM is well known: an electron beam is focused to nanometer-scale onto a given sample where resulting emissions such as backscattered and secondary electrons, X-rays, and visible light are registered. Raster scanning the primary electron beam across the sample then gives a fine-scale image of the surface topography (texture), crystalline structure and orientation, with accompanying elemental composition. The flexibility in the types of measurements the mESEM is capable of, makes it ideally suited for a variety of applications. The mESEM is appropriate for use on multiple planetary surfaces, and for a variety of mission goals (from science to non-destructive analysis to ISRU). We will identify potential applications and range of potential uses related to planetary exploration. Over the past few of years we have initiated fabrication and testing of a proof-of-concept assembly, consisting of a cold-field-emission electron gun and custom high-voltage power supply, electrostatic electron-beam focusing column, and scanning-imaging electronics plus backscatter detector. Current project status will be discussed. This effort is funded through the NASA Research Opportunities in Space and Earth Sciences - Planetary Instrument Definition and Development Program.

    2017-01-01

    Environmental dusts settle on surfaces and influence the performance of concentrated solar energy harvesting devices, such as aluminum troughs. The characteristics of environmental dust and the effects of mud formed from the dust particles as a result of water condensing in humid air conditions on an aluminum wafer surface are examined. The dissolution of alkaline and alkaline earth compounds in water condensate form a chemically active mud liquid with pH 8.2. Due to gravity, the mud liquid settles at the interface of the mud and the aluminum surface while forming locally scattered patches of liquid films. Once the mud liquid dries, adhesion work to remove the dry mud increases significantly. The mud liquid gives rise to the formation of pinholes and local pit sites on the aluminum surface. Morphological changes due to pit sites and residues of the dry mud on the aluminum surface lower the surface reflection after the removal of the dry mud from the surface. The characteristics of the aluminum surface can address the dust/mud-related limitations of reflective surfaces and may have implications for the reductions in the efficiencies of solar concentrated power systems.

    Various etchants/conditioners are used during dental treatment to affect or remove the smear layer. The purpose of this study was to evaluate the effect of different treatments on moist dentine, using a field emission environmental scanning electron microscope (FE-ESEM). Twenty freshly extracted, human molar teeth were utilised. The roots and pulps were removed, and the crowns horizontally sectioned with a low speed diamond saw (Isomet) (with cooling in a saline solution) in order to expose superficial dentine. A smear layer was created on these surfaces by using 600 grit silicone carbide paper. Test surfaces were then treated in one of the following ways: 1. 37% phosphoric acid liquid 2. 37% phosphoric acid gel 3. NRC (non-rinse conditioner) without rinsing 4. NRC with rinsing. Shallow grooves were cut on the untreated sides, using a thin diamond bur. This enabled the samples to be split in half when pressure was applied in the grooves. Samples were maintained moist throughout specimen preparation. Samples were examined in the FE-ESEM (Philips XL 30) in such a way that the effect of the treatment could be viewed occlusally, as well as perpendicular to the treated interface. Phosphoric acid liquid and gel removed the smear layer, and demineralised the dentine for approximately 5-10 micrometers. NRC penetrated the smear layer and modified it to a lesser degree. However, washing of the NRC treated surface removed part of the smear layer, and opened up some dentinal tubules. Excellent resolution was possible with the FE-ESEM in both the wet and dry modes.

    In this work, a mask-free method is introduced for patterned nitrogen doping of graphene using a micro-plasma jet under ambient condition. Raman and X-ray photoelectron spectroscopy spectra indicate that nitrogen atoms are incorporated into the graphene lattice with the two-dimensional spatial distribution precisely controlled in the range of mm down to 10 μm. Since the chemistry of the micro-plasma jet can be controlled by the choice of the gas mixture, this direct writing process with micro-plasma jet can be a versatile approach for patterned functionalization of graphene with high spatial resolution. This could have promising applications in graphene-based electronics.

    Full Text Available O presente artigo propõe uma discussão em torno das possibilidades de uma educação ambiental queer. Tornar queer a educação ambiental significa mais que simplesmente adicionar conteúdo gay/lesbiano/bissexual/transgênero à educação ambiental, mas visa, em seu projeto, problematizar a heteronormatividade, a essencialização das identidades e a heterossexualização de nossas teorias e práticas. Apresentamos neste trabalho uma breve introdução à pedagogia queer e apontamos como a educação ambiental pode contribuir de maneira singular para a interrupção da heteronormatividade e para a problematização da identidade e da experiência. Também exemplificamos esforços por um ambientalismo queer em novos movimentos sociais e produções culturais.We wish to initiate discussion on the possibilities for queering environmental education. As a verb, "to queer" means more than simply adding gay/lesbian/bisexual/transgendered content to environmental education. Rather, queering has, at its heart, the project of problematizing heteronormativity, essentialized identities and the heterosexualization of our theories and practices. In this paper, we provide a brief introduction to queer pedagogy, point to the unique ways in which environmental education can contribute to the disruption of heteronormativity and the problematization of identity and of experience, and describe efforts to queer environmentalism in new social movements and cultural productions.

    Stereotypies are commonly observed in zoo animals, and it is necessary to better understand whether ambient environmental factors contribute to stereotypy and how to affect animal welfare in zoo settings. This study investigated the relationships between stereotypic behaviors and environmental factors including ambient temperatures, humidity, light intensity, sound intensity and number of visitors. Seven giant pandas were observed in three indoor enclosures and three outdoor enclosures. Environmental factors were measured for both indoor and outdoor enclosures and the effect they had on stereotypical behaviors was investigated. Our research found that light intensity significantly correlated with all stereotypies behaviors. Higher environmental temperature reduced the duration of pacing but increased the frequency of pacing, the duration and frequency of door-directed, meanwhile the duration of head-toss. However, we found no noticeable effect of humidity on stereotypic behaviors except for the frequency of head-toss. We also found that sound intensity was not correlated with stereotypies. Finally, the growth of visitors was negatively associated with the duration of door-directed. These results demonstrated that various environmental factors can have significant effects on stereotypic behaviors causing the expression of various stereotypies. Thus, stereotypies in zoo animals may not simply represent suboptimal welfare, but rather might be adopted as a means of coping with an aversive environment. PMID:28107477

    Borrowing from business, quality improvement programs, and strategic planning principles, environmental scanning is gaining popularity in public health practice and research and is advocated as an assessment and data collection tool by federal funding agencies and other health-related organizations. Applicable to a range of current and emerging health topics, environmental scans — through various methods — assess multiple facets of an issue by engaging stakeholders who can ask or answer research questions, exploring related policy, critiquing published and gray literature, collecting and analyzing qualitative and quantitative data in both primary and secondary forms, disseminating findings to internal and external stakeholders, and informing subsequent planning and decision making. To illustrate the environmental scanning process in a public health setting and showcase its value to practitioners in the field, we describe a federally funded environmental scan for a human papillomavirus vaccination project in Kentucky.

    The bioclimatic design profits of the natural resources for the improvement of the construction quality as well as the user's life. The combination of these two concepts within the architectonic design generates an interesting duality to consider within the understanding of the user's physical and psychological environment and the obtaining of a correlation of reality and dreams. Environmental psychology is focused on the researching of the psychological effects of the architectonic environment on the human experience and behavior. Human behavior works under parameters established during its development. Through the habits and styles of life practiced in childhood those parameters establish themselves to later on obtain satisfiers in the search of the life quality of human beings. [Spanish] El diseno bioclimatico aprovecha los recursos naturales para el mejoramiento de la calidad de la construccion y vida del usuario. La combinacion de estos dos conceptos dentro del diseno arquitectonico, genera dualidad interesante de entender el medio ambiente fisico y psicologico de los usuarios y obtener una identificacion entre la realidad y los suenos. La psicologia ambiental se ha enfocado a investigar sobre la relacion de los efectos psicologicos del ambiente construido o arquitectonico sobre la conducta y la experiencia humana. La conducta humana trabaja bajo parametros establecidos durante el desarrollo del mismo, a traves de los habitos y estilos de vida desde su infancia van marcando esos parametros que despues sirven para lograr satisfactores en la busqueda de la calidad de vida de los seres humanos.

Environmental scanning, as a component of absorptive capacity, has been shown to be associated with increased use of innovative treatment techniques at substance abuse treatment programmes. As the transfer of innovative, evidence-based treatment techniques from research to practice is gaining attention, we aimed to identify variables associated with higher levels of environmental scanning among substance abuse treatment clinicians. Method. A cross-sectional survey was administered to 162 clinicians at 15 substance abuse treatment clinics in Michigan. Measures: Environmental scanning was measured by frequency of use of the Internet, journals, seminars or conferences, and people at other treatment clinics for new substance abuse treatment information. Clinicians were asked for their perceptions of their clinic’s openness to new treatment techniques and support for acquiring new information, access to and satisfaction with information sources at work, as well as if they feel it is their job to keep up to date with current treatment research. Additional measures included whether they intended to quit their jobs and whether they were emotionally drained from work. Findings: We found positive associations between environmental scanning and perceived clinic support for acquiring new information, perceived clinic openness to new treatment techniques, access to e-mail and Internet at work, and satisfaction with resources. Turnover intention and being emotionally drained were negatively associated with environmental scanning. Conclusion. : Individual and organizational level variables were found to be associated with higher levels of environmental scanning activity. Although the causal directions of these associations are not known, the findings suggest ways to increase environmental scanning among clinicians.

    Full Text Available This work evaluated the current judicial control of the environmental administrative acts, considering the evolution of the legal doctrine after the Federal Constitution of 1988. The legal conception of the environmental administrative act has, gradually, being modified after the promulgation of the Federal Constitution of 1988. The insertion, in the constitutional text, of directional principles of the public administration, together with specific commandments of the environmental protection, forced the law scholars to modify the traditionalistic vision of the principle of the presumption of legality of the administrative act, when it is able to cause significant environmental damage to biodiversity. Such positioning of the legal doctrine has forced some courts to judge, more severely, the principles of the environmental administrative act, analyzing not only the formal aspects of its establishment, but also its motivation, reasonableness proportionality and purpose. However, the defense of the doctrines of the administrative law in the amplification of the judicial control of the environmental administrative act is not causing a sensible alteration in the jurisprudence that still reflects a positioning of the courts in the exclusive analysis of its formulation. The extended judicial control, although not yet a rule in the judicial analysis of the environmental administrative acts, demonstrates a way to be pursued in the preservation of the natural resources, amplifying and diversifying the existing control mechanisms. = Este trabalho visa avaliar o controle judicial atual dos atos administrativos ambientais, considerando a evolução da doutrina jurídica pós Constituição Federal de 1988, cuja concepção vem, paulatinamente, sendo alterada a partir de então.

    This article is about two important scopes of the Bioclimatical Design (BD), the Social scope and the environmental scope. As an introduction, it is justified the importance of this topic through the association of the BD in the context of sustainability with our country's economic model. The analysis is done under the perspective of effects of the BD on social and environmental scopes. In social scope is used the Cost and Benefit Analysis according to social evaluation. In environmental scope, effects in water, air and ground are studied, but the measurement is done according to the emissions reduction of CO{sub 2} on atmosphere because of the earn on energy consumption. The results of the measurement of this effects are related with economical costs and benefits, which may show a general view about economical, social and environmental scopes. As conclusions, interest results are show and this is proposed to incorporate them in the economical politics.

El estudio se realiza bajo la perspectiva de los impactos que el DB tiene en el aspecto social y en el ambiental. En lo social, se recurre a la metodologia del Analisis Costo-Beneficio para evaluacion Social, en lo ambiental, aunque se tocan los puntos de impacto en aire, agua y uso de suelo, la medicion del impacto se realiza con base en la disminucion de emisiones de CO{sub 2} a la atmosfera por el ahorro en el consumo de energia electrica. Los resultados de la medicion de impactos se cruzan con los costos y beneficios economicos, para presentar un panorama completo en cuanto a aspectos economicos, sociales y ambientales.

    Full Text Available Captivity is an extreme non-natural environment for primates. The success of a breeding colony depends of management and veterinarian procedures which must rely on the knowledge of primates' behavioral needs. Environmental enrichment consists of a series of procedures that improve the quality of life of captive animals by meeting their ethological needs. Enrichment can reduce stress, while increasing animal well being in captivity. Suitable ethical conditions, incidences of behavioral disorders, minimal clinical interventions, low mortality, higher reproduction rates and cost/benefit relationship, reflect directly on the quality of captive breeding colonies. Anthropoids like Neotropical primates possess complex neural structures and relate, in a sophisticated manner, to the environment. This review reports important experiences on enrichment procedures for Neotropical primates and the physiological events which could explain improvement of animal well-being.Cativeiro é um ambiente de extremos não naturais para primatas. O sucesso de uma criação de primatas depende do manejo e de procedimentos veterinários que devem considerar as necessidades etológicas dos animais cativos. Enriquecimento ambiental é um conjunto de técnicas que modificam o ambiente, resultando em uma melhora na qualidade de vida dos animais, ao satisfazer as suas necessidades comportamentais. O enriquecimento pode diminuir o estresse e melhorar o bem-estar. Primatas neotropicais se caracterizam por complexas estruturas neurais e se relacionam de maneira sofisticada com o ambiente. O enriquecimento ambiental pode aumentar a qualidade de uma criação ao adequar o manejo a padrões éticos aceitáveis, estimular o repertório normal do comportamento, diminuir a casuística clínica, diminuir a mortalidade, incrementar a taxa reprodutiva e maximizar a relação custo/benefício em uma criação.

It also discusses - from the standpoint of literature (Buttel, Dunlap, Hanning, among others - its theoretical-methodological and institutional aspects as well in order to understand the obstacles encountered to legitimate and consolidate a set of problems which, until recently, were not dealt with by social sciences. Secondly, it analyses the Brazilian case. Environmental sociology in Brazil is strongly influenced by American empirical sociology, the precursor of the institutionalization process for the themes. On the other hand, further analysis of this case is relevant to understand the relationship between the scientific sphere, and the creation of environmental policies and social movements.Primeiramente o artigo busca a reconstituição e análise histórica inerente ao escopo da sociologia ambiental internacional no contexto da sociologia contemporânea. Ele também discute - a partir da literatura (Buttel, Dunlap, Hanning, entre outros - seus aspectos teórico-metodológicos e institucionais de modo a compreender os obstáculos encontrados para se legitimar e consolidar um conjunto de problemas os quais, até recentemente, não eram trabalhados pelas Ciências Sociais. No segundo momento o artigo analisa o caso brasileiro. A sociologia ambiental no Brasil é fortemente influenciada pela sociologia empírica americana, a precursora no processo de institucionalização desses temas. Por outro lado, uma análise posterior sobre esse caso é relevante para se compreender a relação entre a esfera científica, a implementação de políticas ambientais e os movimentos sociais.

Um dos temas estruturantes desta reunião é a transição para uma economia verde no contexto do desenvolvimento sustentável e da erradicação da pobreza. O tema da Governança Ambiental Global um dos carros chefe do debate na Rio+20, no intuito de promover e acelerar a transição rumo a sociedades sustentáveis, configura a construção muitas vezes, de forma controversa, das condições para a definição de novos espaços institucionais e processos decisórios compartilhados. Este artigo propõe aos leitores uma reflexão para discutir que tipo de sustentabilidade está por trás da economia verde, a sua aplicabilidade e o que deva ser priorizada na discussão de governança ambiental. Isto se explica na medida em que existe a necessidade de mudar os mecanismos de utilização dos recursos, profundamente injustos, e que impedem avanços nos processos decisórios, pois as decisões de poucos tem configurado uma lógica perversa de expropriação de recursos naturais e não resolução da exclusão social.The Rio+20 Conference will mobilize the global community in 2012 to participate in a challenging debate on the global environmental reality and the existing modus operandi with respect to the broad and generic topics of development and the environment.

A atenção é dirigida especialmente às relações entre padrões de distribuição populacional no espaço e a mudança ambiental. Como taxas de mortalidade e fecundidade já passaram por transições enormes, migração é o fator central na mudança populacional e seus impactos sobre o ambiente. No longo prazo, essa é a variável que sempre inspirará preocupação. Embora a grande migração interna da segunda metade do século XX (campo-cidade e inter-regional tenha diminuído consideravelmente, os fluxos intra-regionais continuam a ser importantes. Outros processos de mobilidade, especialmente a migração pendular e o turismo, também afetam a integridade de recursos naturais e terão de ser avaliados continuamente. O zoneamento ecológico-econômico, com seus impactos sobre a mobilidade populacional, será um requisito básico do século XXI.This article reviews research on population and environment, with particular emphasis on the Brazilian case. Attention is focused on the relations between patterns of population mobility and environmental change. With mortality and fertility rates already having experienced major transitions and now experiencing slower change, migration becomes the central factor in population change and its impacts on the environment. In the long term, this is the variable which will always inspire concern. Although the major internal migration in the second half of the 20th century (rural-urban and inter-regional has slowed considerably, intra-regional moves continue to be important. Other mobility processes, especially commuting and tourism, also affect the integrity of natural resources and must be continually evaluated. Ecological-economic zoning, and its impacts on population movements, will be a basic requirement of the 21st century.

    2001-08-01

    The purpose of this research is to study the trajectory of the environmental question in the planning of government policies. For this, the historic process of the emergence and institutionalization of the debate over the environment in the electric sector was redeemed, mainly observing the changes that occurred in the organizational and planning structure of projects. The electric sector is understood to be comprised of the network of interests and social relationships that sustain the set of policies whose principle axis is the generation, transmission and distribution of energy; this network may or may not be extrapolated beyond the design of its institutional structure. During the course of the studies carried out to prepare this thesis, the environmental question was understood, at least in a preliminary fashion, to consist of a general set of problems, diagnoses, situations, plans, programs and actions, as are institutional forms that explicitly refer to the environment as their subject, cause or objective for being or their justification. The research that the work presented here was based upon was oriented by methodological procedures that are characteristic of institutional analyses and representation studies, and used documentation available about and produced by the Electric Sector as a source of information as well as interviews and questionnaires with people directly or indirectly involved with the topic. This procedure allowed for the observation that the treatment of the environmental question in the electric sector underwent moments that varied according to the level of internalization during the different stages of the sector's projects, as well as during the formulation of its institutional policy.

  4. Polymer Electrolyte-Based Ambient Temperature Oxygen Microsensors for Environmental Monitoring

    2011-01-01

    An ambient temperature oxygen microsensor, based on a Nafion polymer electrolyte, has been developed and was microfabricated using thin-film technologies. A challenge in the operation of Nafion-based sensor systems is that the conductivity of Nafion film depends on the humidity in the film. Nafion film loses conductivity when the moisture content in the film is too low, which can affect sensor operation. The advancement here is the identification of a method to retain the operation of the Nafion films in lower humidity environments. Certain salts can hold water molecules in the Nafion film structure at room temperature. By mixing salts with the Nafion solution, water molecules can be homogeneously distributed in the Nafion film increasing the film s hydration to prevent Nafion film from being dried out in low-humidity environment. The presence of organics provides extra sites in the Nafion film to promote proton (H+) mobility and thus improving Nafion film conductivity and sensor performance. The fabrication of ambient temperature oxygen microsensors includes depositing basic electrodes using noble metals, and metal oxides layer on one of the electrode as a reference electrode. The use of noble metals for electrodes is due to their strong catalytic properties for oxygen reduction. A conducting polymer Nafion, doped with water-retaining components and extra sites facilitating proton movement, was used as the electrolyte material, making the design adequate for low humidity environment applications. The Nafion solution was coated on the electrodes and air-dried. The sensor operates at room temperature in potentiometric mode, which measures voltage differences between working and reference electrodes in different gases. Repeat able responses to 21-percent oxygen in nitrogen were achieved using nitrogen as a baseline gas. Detection of oxygen from 7 to 21 percent has also been demonstrated. The room-temperature oxygen micro sensor developed has extremely low power

  5. Development of asthmatic inflammation in mice following early-life exposure to ambient environmental particulates and chronic allergen challenge

    Childhood exposure to environmental particulates increases the risk of development of asthma. The underlying mechanisms might include oxidant injury to airway epithelial cells (AEC. We investigated the ability of ambient environmental particulates to contribute to sensitization via the airways, and thus to the pathogenesis of childhood asthma. To do so, we devised a novel model in which weanling BALB/c mice were exposed to both ambient particulate pollutants and ovalbumin for sensitization via the respiratory tract, followed by chronic inhalational challenge with a low mass concentration of the antigen. We also examined whether these particulates caused oxidant injury and activation of AEC in vitro. Furthermore, we assessed the potential benefit of minimizing oxidative stress to AEC through the period of sensitization and challenge by dietary intervention. We found that characteristic features of asthmatic inflammation developed only in animals that received particulates at the same time as respiratory sensitization, and were then chronically challenged with allergen. However, these animals did not develop airway hyper-responsiveness. Ambient particulates induced epithelial injury in vitro, with evidence of oxidative stress and production of both pro-inflammatory cytokines and Th2-promoting cytokines such as IL-33. Treatment of AEC with an antioxidant in vitro inhibited the pro-inflammatory cytokine response to these particulates. Ambient particulates also induced pro-inflammatory cytokine expression following administration to weanling mice. However, early-life dietary supplementation with antioxidants did not prevent the development of an asthmatic inflammatory response in animals that were exposed to particulates, sensitized and challenged. We conclude that injury to airway epithelium by ambient environmental particulates in early life is capable of promoting the development of an asthmatic inflammatory response in sensitized and antigen-challenged mice.

  7. Calcification intensity in planktonic Foraminifera reflects ambient conditions irrespective of environmental stress

    2013-07-01

    Full Text Available Planktonic Foraminifera are important marine calcifiers, and the ongoing change in the oceanic carbon system makes it essential to understand the influence of environmental factors on the biomineralisation of their shells. The amount of calcite deposited by planktonic Foraminifera during calcification has been hypothesized to reflect a range of environmental factors. However, it has never been assessed whether their calcification only passively responds to the conditions of the ambient seawater or whether it reflects changes in resource allocation due to physiological stress. To disentangle these two end-member scenarios, an experiment is required where the two processes are separated. A natural analogue to such an experiment occurred during the deposition of the Mediterranean sapropels, where large changes in surface water composition and stratification at the onset of the sapropel deposition were decoupled from local extinctions of planktonic Foraminifera species. We take advantage of this natural experiment and investigate the reaction of calcification intensity, expressed as size-normalized weight (SNW, of four species of planktonic Foraminifera to changing conditions during the onset of Sapropel S5 (126–121 ka in a sediment core from the Levantine Basin. We observe a significant relationship between SNW and surface water properties, as reflected by stable isotopes in the calcite of Foraminifera shells, but we failed to observe any reaction of calcification intensity on ecological stress during times of decreasing abundance culminating in local extinction. The reaction of calcification intensity to surface water perturbation at the onset of the sapropel was observed only in surface dwelling species, but all species calcified more strongly prior to the sapropel deposition and less strongly within the sapropel than at comparable conditions during the present day. These results indicate that the high-salinity environment of the glacial

A. resulta de gran importancia en la conservación del medio ambiente al transmitir valores acordes al desarrollo sustentable. Sin embargo, ante el actual paradigma ambiental cabe preguntar: ¿es necesario abordar la E. A. desde una perspectiva más amplia o nuestra visión de ella es reduccionista? La relación de las personas con el medio ambiente necesita adecuarse a la problemática. Esto implica que los esfuerzos y principios de la E. A. deberían adoptarse a nuestra vida cotidiana y aplicarse en esta, haciendo de ella una filosofía de vida, derivada del fuero interno de cada persona, meditada y basada en principios éticos. De esa manera podrían lograrse acciones y actitudes más responsables y comprometidas, que nos beneficien con su cuidado. Un aporte quizá pequeño pero continuo. Abstract. Environmental education (E. E. is of great importance in preserving the environment, transmitting values based on sustainable development. However, given the current environmental paradigm, we must reflect on the question: is it necessary to approach E. E. from a broader perspective or are we seeing E. E. from a narrow perspective? People’s relationship with the environment needs to change. This means that the efforts and principles of E. E. should be adopted and applied in our daily live, making it a philosophy of life, deep inside each person, thoughtful and based on ethical principles. Thus more responsible and committed actions and attitudes could be achieved, which would contribute to environmental care. This may be a small, but continuous contribution.

    2011-02-01

    Superhydrophobic surfaces (SHSs) show promise as promoters of dropwise condensation. Droplets with diameters below ˜10 μm account for the majority of the heat transferred during dropwise condensation but their growth dynamics on SHS have not been systematically studied. Due to the complex topography of the surface environmental scanning electron microscopy is the preferred method for observing the growth dynamics of droplets in this size regime. By studying electron beam heating effects on condensed water droplets we establish a magnification limit below which the heating effects are negligible and use this insight to study the mechanism of individual drop growth.

    2013-12-06

    Surface structure, mobility, and composition of transition metal catalysts were studied by high-pressure scanning tunneling microscopy (HP-STM) and ambient-pressure X-ray photoelectron spectroscopy (AP-XPS) at high gas pressures. HP-STM makes it possible to determine the atomic or molecular rearrangement at catalyst surfaces, particularly at the low-coordinated active surface sites. AP-XPS monitors changes in elemental composition and chemical states of catalysts in response to variations in gas environments. Stepped Pt and Cu single crystals, the hexagonally reconstructed Pt(100) single crystal, and Pt-based bimetallic nanoparticles with controlled size, shape and composition, were employed as the model catalysts for experiments in this thesis.

    2012-12-21

    Due to its ultrahigh electron transmissivity in a wide electron energy range, molecular impermeability, high electrical conductivity and excellent mechanical stiffness, suspended graphene membranes appear to be a nearly ideal window material for in situ (in vivo) environmental electron microscopy of nano- and mesoscopic objects (including bio-medical samples) immersed in liquids and/or in dense gaseous media. In this paper, taking advantage of a small modification of the graphene transfer protocol onto metallic and SiN supporting orifices, reusable environmental cells with exchangeable graphene windows have been designed. Using colloidal gold nanoparticles (50 nm) dispersed in water as model objects for scanning electron microscopy in liquids as proof of concept, different conditions for imaging through the graphene membrane were tested. Limiting factors for electron microscopy in liquids, such as electron beam induced water radiolysis and damage of the graphene membrane at high electron doses, are discussed.

Así, advertiremos que la mayor o menor extensión del fuero "lugar del hecho dañoso", adquiere connotaciones especiales si interpretamos armónicamente los principios de competencia judicial internacional y los principios de protección internacional del medio ambiente. En efecto, la política de protección ambiental, constituye un "valor superior del ordenamiento", y por tanto incide directamente en el juicio razonabilidad que el juez debe realizar sobre el vínculo de conexión. Si bien abordamos el problema desde la experiencia europea, las conclusiones tendrán validez universal.How to solve the problem of objectivity in the link between the court and the action, when engaging civil damages and environmental damages? In other words ¿ can we argue that the place of the harmful event can be determined independently of the persons involved? ¿Is favor Iaesi principle relevant in cases of environmental damage? We propose analyze those problems through the connections between International Civil Jurisdiction principles and environmental protection principles. In fact, environmental protection policy constitutes a "superior value". Therefore it affects directly the judge opinion about the connection link. Our approach is European, but the findings have universal validity.

    Full Text Available The environmental education applied within indigenous schools, flowing from categories of fundamental rights overseen in the current Brazilian Constitution, deserves a great deal of reflection and attention by Brazilian educators. Besides promoting the specific elements proper to schools, they should be aware of the root principle of an environmental education shared by indigenous peoples, being the grounds for other equally relevant sub-principles which demand the involvement of the whole community: the promotion of interculturality, transversality and flexible approaches to environmental education in indigenous schools’ syllabuses, undertaken by children and young natives who require a methodology which is more tuned to their social dynamic and, above all, linked to the natural world. This quality of environmental education upholds a view of the sentiment of fraternity, which we should share equally with present and future generations. = A educação ambiental aplicada nas escolas indígenas, decorrente das categorias de direitos fundamentais previstos na atual Constituição Brasileira, merece muita reflexão e atenção por parte dos educadores brasileiros. Estes, além de promoverem as especificidades que lhes são próprias, devem estar atentos ao princípio matriz de uma educação ambiental compartilhada pelos povos indígenas, sede de outros sub-princípios igualmente relevantes. Esses exigem o envolvimento de toda a comunidade; promoção da interculturalidade, transversalidade e flexibilização de uma educação ambiental no currículo das escolas indígenas, protagonizadas por crianças e jovens índios que requerem uma metodologia mais afinada com a sua dinâmica social e principalmente vinculada às coisas da natureza. Educação ambiental dessa qualidade não perde de vista o sentimento de fraternidade que se deve compartilhar tanto com as nossas presentes e futuras gerações.

  5. 3D chemical mapping: application of scanning transmission (soft) X-ray microscopy (STXM) in combination with angle-scan tomography in bio-, geo-, and environmental sciences.

    Obst, Martin; Schmid, Gregor

    2014-01-01

    The identification of environmental processes and mechanisms often requires information on the organochemical and inorganic composition of specimens at high spatial resolution. X-ray spectroscopy (XAS) performed in the soft X-ray range (100-2,200 eV) provides chemical speciation information for elements that are of high biogeochemical relevance such as carbon, nitrogen, and oxygen but also includes transition metals such as iron, manganese, or nickel. Synchrotron-based scanning transmission X-ray microscopy (STXM) combines XAS with high resolution mapping on the 20-nm scale. This provides two-dimensional (2D) quantitative information about the distribution of chemical species such as organic macromolecules, metals, or mineral phases within environmental samples. Furthermore, the combination of STXM with angle-scan tomography allows for three-dimensional (3D) spectromicroscopic analysis of bio-, geo-, or environmental samples. For the acquisition of STXM tomography data, the sample is rotated around an axis perpendicular to the X-ray beam. Various sample preparation approaches such as stripes cut from TEM grids or the preparation of wet cells allow for preparing environmentally relevant specimens in a dry or in a fully hydrated state for 2D and 3D STXM measurements. In this chapter we give a short overview about the principles of STXM, its application to environmental sciences, different preparation techniques, and the analysis and 3D reconstruction of STXM tomography data.

    A new methodology for quantitative characterization of the coalescence process of waterborne polymer dispersion (latex) particles by environmental scanning electron microscopy (ESEM) is proposed. The experimental setup has been developed to provide reproducible latex monolayer depositions, optimized contrast of the latex particles, and a reliable readout of the sample temperature. Quantification of the coalescence process under dry conditions has been performed by image processing based on evaluation of the image autocorrelation function. As a proof of concept the coalescence of two latexes with known and differing glass transition temperatures has been measured. It has been shown that a reproducibility of better than 1.5 °C can be obtained for the measurement of the coalescence temperature.

    By using environmental scanning electron microscopy, the morphological changes of Vero cells attached to and grown on the microcarrier Cytodex-3 were observed, and their behavior of adhesion, spreading and proliferation was analyzed. The effect of exogenous fibronectin/ laminin on adhesion and spreading of MCC/Vero cell was studied. The images of ESEM showed that expansion of cell growth was directed toward vacancy space. The growth curve and cell concentration change during the whole culture process were obtained from the statistical counting method based on ESEM images and the crystal violet method. The growth rate of Vero cells increases with increasing the concentration of cell inoculation, that is, the specific growth rate increases quickly with increasing the concentration of cell inoculation. When serum concentration in medium #199 ranged from 5% to 10%, experimental results indicated that serum concentration is one of the important factors influencing cell growth, particularly in the cell adhesion and spreading stage.

    We investigated the characteristics of ambient particles and their relationships with various environmental factors,including gaseous pollutants (CH4,non-methane hydrocarbons (NMHC),total hydrocarbons (THC),NOx,CO,SO2),meteorological parameters (humidity,temperature),and time (day/night,workday/weekend).We used an electrical low-pressure cascade impactor to measure the number and size distributions of ambient particles (0.007-10 μm) that were collected approximately 1 km northwest of Hsinchu Science Park in Talwan between February and May 2007.The number concentrations of particles were enhanced through photochemical reactions during the day.In addition,high traffic flow during workdays increased the formation of particulates.Except for SO2,all of the gaseous pollutants we studied (CH4,NMHC,THC,NOx,CO) correlated positively with the total number concentrations of ambient particles during daytime,indicating that they might contribute to the particulate burden.The poorer relationship between the SO2 level and the total number concentration of particles suggests that SO2 might participate indirectly in the nucleation process during particle formation,The high enrichment factors for Zn,Pb,Cu,and Mn,which mostly comprised the ultrafine particles (diameter:< 0.1 μm) and fine particles (diameter:0.1-1 μm),presumably arose from emissions from traffic and high technology factories.Heterogeneous reactions on solid particles might play a role in the removal of SOx and NOx from the atmosphere.Sulfides and nitrides can further react with these local pollutants,forming specific Cu-containing compounds:CuO (39%),CuSO4 (34%),and Cu(NO3)2 (27%),within the ambient particles in this industrial area.

    For more than 40 years, the United States has produced nuclear weapons. These production activities generated both radioactive and hazardous waste and often contaminated the environment. For many years, the public was unaware of the problem and unable to do anything about it. All of this has changed. In response to recent public outcry, the former Secretary of Energy, Retired Admiral James D. Watkins, established the Office of Environmental Restoration and Waste Management (EM) in November 1989. The creation of EM was the first step toward correcting contamination problems from the past 40 years In this booklet, we at DOE, through the efforts of the students at Oak Hills High School of Cincinnati, Ohio, will introduce you to EM and encourage your involvement in this major program within the Department of Energy. [Espanol] Durante mas de 40 anos, los Estados Unidos fabricaron armamentos nucleares. Esta produccion genero residuos radiactivos y peligrosos y, en muchos casos, contaminaron el medio ambiente.

Respondiendo a crecientes protestas publicas, el ex Secretario de Energia Almirante James D. Watkins, establecio en noviembre de 1989 la Subsecretaria de Administracion Ambiental. La creacion de esta Subsecretaria fue el primer paso que dio el Departamento de Energia para corregir los problemas de contaminacion ambiental de los ultimos 40 anos.

    Small vertebrate model organisms have recently gained popularity as attractive experimental models that enhance our understanding of human tissue and organ development. Despite a large body of evidence using optical spectroscopy for the characterization of small model organism on chip-based devices, no attempts have been so far made to interface microfabricated technologies with environmental scanning electron microscopy (ESEM). Conventional scanning electron microscopy requires high vacuum environments and biological samples must be, therefore, submitted to many preparative procedures to dehydrate, fix, and subsequently stain the sample with gold-palladium deposition. This process is inherently low-throughput and can introduce many analytical artifacts. This work describes a proof-of-concept microfluidic chip-based system for immobilizing zebrafish larvae for ESEM imaging that is performed in a gaseous atmosphere, under low vacuum mode and without any need for sample staining protocols. The microfabricated technology provides a user-friendly and simple interface to perform ESEM imaging on zebrafish larvae. Presented lab-on-a-chip device was fabricated using a high-speed infrared laser micromachining in a biocompatible poly(methyl methacrylate) thermoplastic. It consisted of a reservoir with multiple semispherical microwells designed to hold the yolk of dechorionated zebrafish larvae. Immobilization of the larvae was achieved by a gentle suction generated during blotting of the medium. Trapping region allowed for multiple specimens to be conveniently positioned on the chip-based device within few minutes for ESEM imaging.

    To date, the available equipment for characterising the microstructure of membrane electrode assembly (MEA) is still not well developed. For example, applying the normal scanning electron microscope (SEM) only provides information on the dry structure of MEAs. This paper presents a microstructure analysis method of MEAs in proton exchange membrane fuel cells (PEMFC). The microstructure analysis in this paper utilises the environmental scanning electron microscope (ESEM), which shows its advantage on the sample microstructure analysis in wet mode. When water is present, the characteristics of the MEA, especially the hydrophobic and/or hydrophilic properties, are distinguishable on the ESEM images. With proper temperature and pressure control, the water distribution within both the membrane and the catalyst layer can be viewed by ESEM. Based on ESEM measurement and mercury porosity measurement, the distributions of hydrophobic and hydrophilic pores in MEA have been analyzed. By means of ESEM and energy dispersive X-ray (EDX), a degraded MEA is characterized. The microstructure change of the degraded MEA has been discussed. The results provide helpful information for the understanding of MEAs in PEMFC. (author)

    Full Text Available A educação ambiental surge como uma das possíveis estratégias para o enfrentamento da crise civilizatória de dupla ordem, cultural e social. Sua perspectiva crítica e emancipatória visa à deflagração de processos nos quais a busca individual e coletiva por mudanças culturais e sociais estão dialeticamente indissociadas. A articulação de princípios de Estado e comunidade, sob a égide da comunidade, coloca o Estado como parceiro desta no processo de transformação do status quo situado, segundo Boaventura de Souza Santos, como um "novíssimo movimento social". A tal Estado cumpre o papel de fortalecer a sociedade civil como sede da superestrutura. No campo ambiental, o Estado tem crescido em termos de marcos regulatórios sem uma capacidade operacional que condiga com a demanda em vista da redução do Estado (década de 1990 e da ausência de reformas que não sejam a do Estado mínimo. À educação ambiental cumpre, portanto, contribuir com o processo dialético Estado-sociedade civil que possibilite uma definição das políticas públicas a partir do diálogo. Nesse sentido, a construção da educação ambiental como política pública, implementada pelo Ministério da Educação e Cultura (MEC e pelo Ministério do Meio Ambiente (MMA, implica processos de intervenção direta, regulamentação e contratualismo que fortalecem a articulação de diferentes atores sociais (nos âmbitos formal e não formal da educação e sua capacidade de desempenhar gestão territorial sustentável e educadora, formação de educadores ambientais, educomunicação socioambiental e outras estratégias que promovam a educação ambiental crítica e emancipatória.

    The cost and practicality of greenhouse gas removal processes, which are critical for environmental sustainability, pivot on high-value secondary applications derived from carbon capture and conversion techniques. Using the solar thermal electrochemical process (STEP), ambient CO2 captured in molten lithiated carbonates leads to the production of carbon nanofibers (CNFs) and carbon nanotubes (CNTs) at high yield through electrolysis using inexpensive steel electrodes. These low-cost CO2-derived CNTs and CNFs are demonstrated as high performance energy storage materials in both lithium-ion and sodium-ion batteries. Owing to synthetic control of sp(3) content in the synthesized nanostructures, optimized storage capacities are measured over 370 mAh g(-1) (lithium) and 130 mAh g(-1) (sodium) with no capacity fade under durability tests up to 200 and 600 cycles, respectively. This work demonstrates that ambient CO2, considered as an environmental pollutant, can be attributed economic value in grid-scale and portable energy storage systems with STEP scale-up practicality in the context of combined cycle natural gas electric power generation.

    Air pollutants have adverse effects on the Earth's climate system. There is an urgent need for cost-effective devices capable of recognizing and detecting various ambient pollutants. An FTIR photoacoustic spectroscopy (FTIR-PAS) method based on a commercial FTIR spectrometer developed for air contamination monitoring will be presented. A resonant T-cell was determined to be the most appropriate resonator in view of the low-frequency requirement and space limitations in the sample compartment. Step-scan FTIR-PAS theory for regular cylinder resonator has been described as a reference for prediction of T-cell vibration principles. Both simulated amplitude and phase responses of the T-cell show good agreement with measurement data Carbon dioxide IR absorption spectra were used to demonstrate the capacity of the FTIR-PAS method to detect ambient pollutants. The theoretical detection limit for carbon dioxide was found to be 4 ppmv. A linear response to carbon dioxide concentration was found in the range from 2500 ppmv to 5000 ppmv. The results indicate that it is possible to use step-scan FTIR-PAS with a T-cell as a quantitative method for analysis of ambient contaminants.

    The interaction of O2 with the Ag(111) surface was studied with scanning tunneling microscopy (STM) in the pressure range from 10- 9 Torr to 1 atm at room temperature and with X-ray photoelectron spectroscopy (XPS) up to 0.3 Torr O2 in the temperature range from RT to 413 K. STM images show that the Ag(111) surface topography is little affected in regions with large flat terraces, except for the appearance of mobile features due to oxygen atoms at pressures above 0.01 Torr. In regions where the step density is high, the surface became rough under 0.01 Torr of O2, due to the local oxidation of Ag. Various chemical states of oxygen due to chemisorbed, oxide and subsurface species were identified by XPS as a function of pressure and temperature. The findings from the STM images and XPS measurements indicate that formation of an oxide phase, the thermodynamically stable form at room temperature under ambient O2 pressure, is kinetically hindered in the flat terrace areas but proceeds readily in regions with high-step density.

    With the coming of the Constitutional Emend n. 9/95, the Brazilian market of oil and natural gas stopped being monopolized by PETROBRAS. Since then, the concession of blocks began to be preceded by the public tender procedure realized by ANP- National Agency of Oil. The activities of oil exploration and production are potentially damaging to environment, what brings necessary the environmental licence and the previous study of the environmental impacts caused in this activity. Considering that the environmental licence must be done after the tender process, the enterprises that bought the blocks would assume the risk of not being allowed to practice their activities because of the absence of the environmental licence. To avoid that the It's offered blocks in not viable areas for oil exploration, the ANP, responsible for the public tender must accomplish a previous environmental control, to assure to the enterprises involved the environmental viability of the blocks offered. This project will touch the question of how has been realized the previous environmental control of the blocks offered by ANP into the public tender process, detaching, the control done at the 6.

Sobre essa trilha, planejada para ser executada com alunos do ensino fundamental, indaga-se, sobretudo, sobre o processo que culminou na elaboração de seu traçado. Na segunda parte do trabalho, focam-se as trilhas interpretativas desencadeadas em um Parque Estadual de Proteção Ambiental localizado nas proximidades de Porto Alegre/RS. Para tanto, mostram-se os processos de disciplinamento dos sujeitos que estão em jogo nessas iniciativas, bem como a produção discursiva de uma natureza intangível operada nessas ações. As análises empreendidas no ensaio estão situadas no campo multifacetado e contestado dos estudos culturais. A partir desse campo, o trabalho discorre sobre as leituras da natureza que estariam sendo construídas nas atividades de Educação Ambiental focadas neste ensaio: as chamadas trilhas interpretativas. E mais, a partir dos estudos culturais indaga-se a instituição dos entendimentos sobre a natureza (e dos modos de agir em relação a ela a partir das práticas e dos discursos envolvidos desde o planejamento e a implantação de uma trilha interpretativa, até o momento em que é desenvolvido um trabalho educativo em tais espaços.This paper inquires into the

    The Direccion de Vigilancia Radiologica (DVR) of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) de Mexico, performs several function for environmental radiation monitoring. One of these functions is the permanent monitoring of the environmental gamma radiation. For this, it implemented the Red Nacional Automatica de Monitoreo Radiologico Ambiental (RENAMORA) - the National Automated Network for Environmental Radiation Monitoring,which currently comprises 60 detector probes for gamma radiation which with a programmable system that includes information technologies, data transmission and software can send the information in real time to a primary center of data located in the facilities of CNSNS. - When the data are received, the system performs the verification and extraction of the information organized in Tables and charts, and generates a report of environmental gamma radiation dose rate average for each of the probes and for each period of time determined bu CNSNS. The RENAMORA covers the main cities and allows to establish the bases of almost the entire country, as well as to warn about abnormal situations caused by incidents or natural events generated by human activities inside or outside the country which involves radioactive materials; paying special attention to main radiological sites, such as the surroundings of the Laguna Verde Nuclear Power Plants, research centers and the radioactive waste disposal sites.

    This work presents considerations on Ergonomics and Design for Sustainability in the healthcare field based on research experiences of the Technology and Design for Healthcare (TeDH) research group of INDACO (Industrial design, communication, arts and fashion) department of Politecnico di Milano. In order to develop a multidisciplinary approach to design able to answer to specific user needs such as elderly in an environmental sustainable way (1) this paper shows the results we achieved concerning ergonomics and environmental impact in product development (2), the extension of this approach to interior and home design and the advantage of the application of Information Communication Technologies (ICT). ICT can help people with special needs to make their everyday life easier and more safe, at the same time, ICT can make social-environmental impact of everyday behavior evident and can be applied to manage sustainability. The specific theme is thus to integrate ergonomics and sustainability competences in the development of Ambient Assisted Living through a Product- Service System approach. The concept of product service system has the potential to improve product performances and services, establish new relations and networks with different actors in order to satisfy user needs and apply a systems approach considering environmental, social and economic factors in the users' environment.

    2002-05-01

    Full Text Available Defining environmental chemistry is a not an easy task because it encompasses many different topics. According to Stanley E. Manahan, author of a classical textbook of Environmental Chemistry, this branch could be defined as the one centered in the study of the sources, transport, effects and fates of chemical species in the water, soil, and air environments, as well as the influence of human activity upon these processes. More recently, new knowledge emerged from the Environmental Toxicology allowed to go even deeper in the meaning of 'effects' and 'fates' of a continuous growing number of organic and inorganic species disposed in water bodies, soils and atmosphere. Toxicity tests became an important tool to evaluate the environmental impact of such species to a great number of organisms, thus allowing to set quality criteria for drinking water, sediments and biota. The state of art shows that environmental chemistry is a multi-inter disciplinary science by nature; therefore, it needs more than a limited, unique-approach and non-oriented set of data to understand the nature of natural processes. Taking all these aspects into consideration, one can say that Environmental Chemistry in Brazil is now a well established area of research within the classical areas of the Chemistry, with a large number of emerging groups as well research groups with worldwide recognition.

    2014-03-01

    Collagen is an abundant protein and its monomers covalently crosslink to form fibrils which form fibers which contribute to forming macrostructures like tendon or bone. While the contribution is well understood at the macroscopic level, it is not well known at the fibril level. We wish to study the mechanical properties of collagen for networks of collagen fibers that vary in size and density. We present here a method to synthesize collagen networks from monomers and that allows us to vary the density of the networks. By using biotynilated collagen and a surface that is functionalized with avidin, we generate two-dimensional collagen networks across the surface of a silicon wafer. During network synthesis, the incubation time is varied from 30 minutes to 3 hours or temperature is varied from 25°C to 45°C. The two-dimensional collagen network created in the process is characterized using environmental atomic force microscopy (AFM) and scanning electron microscopy (SEM). The network density is measured by the number of strands in one frame using SPIP software. We expect that at body temperature (37°C) and with longer incubation times, the network density should increase.

    Full Text Available Purpose. To investigate the structure and irregularity of the capsulotomy cutting edges created by two femtosecond (FS laser platforms in comparison with manual continuous circular capsulorhexis (CCC using environmental scanning electron microscopy (eSEM. Methods. Ten anterior capsulotomies were obtained using two different FS laser cataract platforms (LenSx, n=5, and Victus, n=5. In addition, five manual CCC (n=5 were obtained using a rhexis forceps. The specimens were imaged by eSEM (FEI Quanta 400, OR, USA. Objective metrics, which included the arithmetic mean deviation of the surface (Sa and the root-mean-square deviation of the surface (Sq, were used to evaluate the irregularity of both the FS laser capsulotomies and the manual CCC cutting edges. Results. Several microirregularities were shown across the FS laser capsulotomy cutting edges. The edges of manually torn capsules were shown, by comparison of Sa and Sq values, to be smoother (P<0.05 than the FS laser capsulotomy edges. Conclusions. Work is needed to understand whether the FS laser capsulotomy edge microirregularities, not seen in manual CCC, may act as focal points for the concentration of stress that would increase the risk of capsular tear during phacoemulsification as recently reported in the literature.

    The aim of this paper is to describe an optimized methodology to study the surface characteristics and internal structure of biopolymer capsules using scanning electron microscopy (SEM) in environmental mode. The main advantage of this methodology is that no preparation is required and, significantly, no metallic coverage is deposited on the surface of the specimen, thus preserving the original capsule shape and its surface morphology. This avoids introducing preparation artefacts which could modify the capsule surface and mask information concerning important feature like porosities or roughness. Using this method gelatin and mainly fatty coatings, difficult to be analyzed by standard SEM technique, unambiguously show fine details of their surface morphology without damage. Furthermore, chemical contrast is preserved in backscattered electron images of unprepared samples, allowing visualizing the internal organization of the capsule, the quality of the envelope, etc... This study provides pointers on how to obtain optimal conditions for the analysis of biological or sensitive material, as this is not always studied using appropriate techniques. A reliable evaluation of the parameters used in capsule elaboration for research and industrial applications, as well as that of capsule functionality is provided by this methodology, which is essential for the technological progress in this domain.

  17. Master curves for gas amplification in low vacuum and environmental scanning electron microscopy.

    2004-02-01

    The concept of universal amplification profiles for gas cascade amplification of signals in low vacuum and environmental scanning electron microscopes is demonstrated both experimentally and theoretically using water vapor. For a given gas, cascade amplification gain profiles can be plotted onto a single master curve where the independent reduced parameter is the ratio of pressure to amplification field strength. When plotted in this fashion, both desired secondary electron and spurious background signal components fall onto respective master curves, with the amplitude being a function of anode bias only. These master curves can be described by simple Townsend Gas Capacitor equations using only two gas-specific parameters. As long as single scattering conditions apply, this approach allows for simplified, direct comparison of the gain characteristics of different gases and allows more intelligent selection of imaging conditions. The utility of treating signal amplification in this manner is demonstrated through a series of images collected under a variety of conditions, but with the ratio of pressure to amplification field strength kept constant. In practice, the range of operational parameter space in which this description can be applied to imaging is limited, as images typically have a mixture of secondary and backscattered contributions.

    Full Text Available This study describes the colleters of Morinda citrifolia L. (Rubiaceae by using environmental scanning electron microscopy (ESEM and energy dispersive x-ray spectroscopy (EDS. Two different developmental stages were characterized as well as the chemical composition of secretion. Colleters are secretory structures that produce mucilage protecting the meristems and leaf primordia against desiccation and/or pathogens. Although these secretory structures are common on Rubiaceae, the results reported here is to the best of our knowledge the first record of colleters on Morinda genus. Colleters are present at the stipule adaxial surface, distributed in lines. These secretory structures are standard type and have no base constriction, differently from all studied species until now. In order to better understand the colleters structure and secretion, two phases were distinguished: a secretory phase and a senescence one. On secretory phase standard type colleters were visualized between leaf primordia and stipule, emerge on secretion. They present smooth surface, however was also possible to observe the contours of secretory cells anticlinal walls. In senescent phase colleters morphology was alternated exhibiting rough surface and blunt to point tips. The surface was rough and on stipule sections was possible to observe idioblasts with raphides bundles. The secretion process of M. citrifolia colleters occurs with the disruption of cuticle and the chemical elements are mostly dominated by carbon and oxygen.

    Multidisciplinary team approach is an essential component of evidence-based wound management in the community. The objective of this study was to identify and describe community-based multidisciplinary wound care teams in Ontario. For the study, a working definition of a multidisciplinary wound care team was developed, and a two-phase field evaluation was conducted. In phase I, a systematic survey with three search strategies (environmental scan) was conducted to identify all multidisciplinary wound care teams in Ontario. In phase II, the team leads were surveyed about the service models of the teams. We identified 49 wound care teams in Ontario. The highest ratio of Ontario seniors to wound team within each Ontario health planning region was 82,358:1; the lowest ratio was 14,151:1. Forty-four teams (90%) participated in the survey. The majority of teams existed for at least 5 years, were established as hospital outpatient clinics, and served patients with chronic wounds. Teams were heterogeneous in on-site capacity of specialized diagnostic testing and wound treatment, team size, and patient volume. Seventy-seven percent of teams had members from three or more disciplines. Several teams lacked essential disciplines. More research is needed to identify optimal service models leading to improved patient outcomes.

    Access to specialist care is a point of concern for patients, primary care providers, and specialists in Canada. Innovative e-health platforms such as electronic consultation (eConsultation) and referral (eReferral) can improve access to specialist care. These systems allow physicians to communicate asynchronously and could reduce the number of unnecessary referrals that clog wait lists, provide a record of the patient's journey through the referral system, and lead to more efficient visits. Little is known about the current state of eConsultation and eReferral in Canada. The purpose of this work was to identify current systems and gain insight into the design and implementation process of existing systems. An environmental scan approach was used, consisting of a systematic and grey literature review, and targeted semi-structured key informant interviews. Only three eConsultation/eReferral systems are currently in operation in Canada. Four themes emerged from the interviews: eReferral is an end goal for those provinces without an active eReferral system, re-organization of the referral process is a necessity prior to automation, engaging the end-user is essential, and technological incompatibilities are major impediments to progress. Despite the acknowledged need to improve the referral system and increase government spending on health information technology, eConsultation and eReferral systems remain scarce as Canada lags behind the rest of the developed world.

    Nowadays, environmental indicators are widely used as effective tools to assist decision-making in both public and private sectors. The lack of literature and research about local and regional Environmental Condition Indicators (ECI), the poor knowledge regarding solid waste generation, effluents and gas emissions from foundry industries, and their particular location in the urban area of Tandil, Argentina are the main reasons for this investigation, aiming to develop a set a of ECI to provide information about the environment in relation to the foundry industry. The study involves all the foundries located in the city between March and April 2010. The set of ECI developed includes 9 indicators for air, 5 for soil and 1 for water.

    To subsidize its contingency plans for oil leaks, TRANSPETRO, subsidiary of PETROBRAS, set up an internal program with a big extension to obtain Environmental Sensibility Maps over a strip of twenty kilometers of width along more than five thousand kilometers of pipelines. Due to the pioneer characteristic of these natural survey (thematic cartography) it was opted a first approach for integration of this information in 1:50.000 scale. Based on a Geographical Information System (GIS), it was opted the supervised geo processing resources, compiling, firstly, the elevation, soil and geological maps for generation of the physical environment vulnerability units. Using a combination by weight average, ten vulnerability units were generated and were improved through aggregation in five units to decrease the complexity of the representation in map. These classes represent the combinations of variables of the physical environment that can be recognized by theirs corresponding landscapes. Based on interpretation of orbital LANDSAT TM images, aided by verifications in aerial photograph and a systematic survey of notable points of environmental observation (PVAs) along the pipelines, it was elaborated a general map of soil use and vegetable coverage. The classes of this theme were combined with the classes of physical vulnerability environment to generate five classes of Environmental Sensibility (Environmental Sensibility Maps). Over this theme, were attributed the representations of the main types of vegetable coverage and occupation of the soil, as well as the fauna and the other social-economics aspects, obtaining therefore a map with all the essential controller information of the environmental protection measures.

    2016-01-01

    Full Text Available Coal gangue, one of the main hazardous emissions of purifying coal from coalmine industry, is rich in silica and alumina. However, the recycling of the waste is normally restricted by less efficient techniques and low attractive output; the utilization of such waste is still staying lower than 15%. In this work, the silica aerogel materials were synthesized by using a precursor extracted from recycled silicon-rich coal gangue, followed by a single-step surface silylation and ambient pressure drying. A low density (~0.19 g/cm3 nanostructured aerogel with a 3D open porous microstructure and high surface area (~690 m2/g was synthesized, which presents a superior thermal insulation performance (~26.5 mW·m−1·K−1 of a plane packed of 4-5 mm granules which was confirmed by transient hot-wire method. This study offers a new facile route to the synthesis of insulating aerogel material by recycling solid waste coal gangue and presents a potential cost reduction of industrial production of silica aerogels.

    This plan of monitoring radiological environmental routine fits on environmental policy of CNEA, satisfying national and international recommendations for licensed facilities. Sampling matrices are related to direct routes of exposure: air and water (river, lake, sediments, drinking water). Soil samples are also analyzed for having integrated matrices. They are considered as minimum three points of measurement: a white point (water or winds up), a point of maximum (water or winds down) and a point corresponding to the location of the individual representative or a point of public interest. Measurements in air estimate KERMA rate with thermoluminescent dosimeters, bi-monthly, and concentrations of particulate material and aerosols. For water samples (monthly), soil and sediments (quarterly), radionuclides that have download limits are analyzed, according to its importance in the dosages produced in the representative individual. In these cases artificial radionuclides using gamma spectrometry, beta total and Sr-90 by radiochemical techniques if the value of total screening (1 Bq/L) is exceeded. Foods are not included because no possible matrices were detected, either by their distance. by located not predominant wind direction. They are however still looking for milk producers that fulfills the minimum requirements.The data collected are compared with environmental baselines to set trends that might point to future significant changes in the environment during the life of the facilities. So far it was not observed significant differences with respect to baseline values.

    Full Text Available Abstract Background Pedestrian injury frequently results in devastating and costly injuries and accounts for 11% of all road user fatalities. In the United States in 2006 there were 4,784 fatalities and 61,000 injuries from pedestrian injury, and in 2007 there were 4,654 fatalities and 70,000 injuries. In Canada, injury is the leading cause of death for those under 45 years of age and the fourth most common cause of death for all ages Traumatic pedestrian injury results in nearly 4000 hospitalizations in Canada annually. These injuries result from the interplay of modifiable environmental factors. The objective of this study was to determine links between the built environment and pedestrian injury hotspots in Vancouver. Methods Data were obtained from the Insurance Corporation of British Columbia (ICBC for the 6 year period from 2000 to 2005 and combined with pedestrian injury data extracted from the British Columbia Trauma Registry (BCTR for the same period. High incident locations (hotspots for pedestrian injury in the City of Vancouver were identified and mapped using geographic information systems (GIS, and the characteristics of the built environment at each of the hotspot locations were examined by a team of researchers. Results The analysis highlighted 32 pedestrian injury hotspot locations in Vancouver. 31 of 32 hotspots were situated on major roads. Likewise, the majority of hotspots were located on downtown streets. The 'downtown eastside' was identified as an area with multiple high-incident locations, including the 2 highest ranked pedestrian injury hotspots. Bars were present at 21 of the hotspot locations, with 11 of these locations being judged to have high alcohol establishment density. Conclusion This study highlighted the disproportionate burden of pedestrian injury centred on the downtown eastside area of Vancouver. The environmental scan revealed that important passive pedestrian safety countermeasures were only present at a

    The aim of this paper is to describe an optimized methodology to study the surface characteristics and internal structure of biopolymer capsules using scanning electron microscopy (SEM) in environmental mode. The main advantage of this methodology is that no preparation is required and, significantly, no metallic coverage is deposited on the surface of the specimen, thus preserving the original capsule shape and its surface morphology. This avoids introducing preparation artefacts which could modify the capsule surface and mask information concerning important feature like porosities or roughness. Using this method gelatin and mainly fatty coatings, difficult to be analyzed by standard SEM technique, unambiguously show fine details of their surface morphology without damage. Furthermore, chemical contrast is preserved in backscattered electron images of unprepared samples, allowing visualizing the internal organization of the capsule, the quality of the envelope, etc.… This study provides pointers on how to obtain optimal conditions for the analysis of biological or sensitive material, as this is not always studied using appropriate techniques. A reliable evaluation of the parameters used in capsule elaboration for research and industrial applications, as well as that of capsule functionality is provided by this methodology, which is essential for the technological progress in this domain. - Highlights: • We optimized a methodology using ESEM to analyze biopolymer capsules. • This methodology allows analyzing original surface samples without any preparation. • No preparation artefact are introduced which would mask important surface details. • Morphological details and chemical contrast from the original surface are preserved. • Capsule shape, volume, surface roughness and coating quality were reliably evaluated.

    Full Text Available Environmental radioactive pollution is produced mainly by the use of natural or artificial radioactive substances, the use of the nuclear power and nuclear weapons, constituting a great danger of contamination for the nature and the humanity; since many residues of these polluting materials have been scattered by all the earth. The risks of the radioactive contamination for the people and the environment depend on the nature of the radioactive contaminant, the pollution level and the extension of the contamination; since all the radiations are genotoxics, the probability of genetic alterations and production of mutations is going to depend on the exposure degree of the cells of an organism. In the last years, the environmental radioactive pollution hazards due to artificial radionuclides were reduced considerably, the scientific community has paid special interest in the contamination with natural radioactive elements like for example the radon released within the underground mines that the probability of occurrence of cancer of lung between the workers and the accumulation of different materials NORMS in mining activities increases, especially in the uranium zones of Pozo de Caldas (Brazil and Macusani (Peru, zones of phosphoric operation of rocks (Bayovar or polimetalic mining; the inadequate treatment of these materials is going to produce an important radiological impact and to alter to the habitat of different communities from plants and animals in the region.

    In situ ambient pressure X-ray photoelectron spectroscopy (APPES) and scanning force microscopy were used to characterize the surface discharge induced by water layers grown on (001) surfaces of sodium chloride single crystals. The APPES studies show that both kinetic energy (KE) and full width at half-maximum (FWHM) of the Na 2s and Cl 2p core level peaks, monitored as a function of relative humidity (RH), mimic surface conductivity curves measured using scanning force microscopy. The KE position and FWHM of the core level peaks therefore are directly related to the solvation and diffusion of ions at the NaCl(100) surface upon adsorption of water.

É comprovado que muitos de seus compostos químicos são tóxicos ou cancerígenos e que sua inalação pode causar vários danos à saúde. Embora, salvo em áreas especificadas, proibido por lei, o fumo em recintos coletivos é comum no Brasil e, na maioria dos casos, as áreas destinadas a ele, quando existentes, não são devidamente isoladas, prejudicando os não-fumantes. A indústria do tabaco e a da hospitalidade vendem a ventilação como a solução desse problema, mas estudos indicam que ela não o é. Este artigo aborda a problemática da exposição à FAC por seus aspectos ligados à saúde e à poluição.Environmental tobacco smoke (ETS is a major contributor to indoor air concentrations and exposure to particles. It's known that many of its chemical compounds are toxic or carcinogens and its inhalation may cause many health injuries.

    The bio diesel production was encouraged since the entire world is looking for new energy sources. However, the bio diesel process produces large amounts of glycerin as byproduct. Therefore, innovative uses for this new glycerin source must be sought so as to avoid the collapse of the animal glycerin chain. In this context, the production of resins is interesting due to the likeness between these polymers and the petroleum, with these resins being promising as spill cleanup agents. In the present work, magnetic foams were prepared with insertion of maghemite nanoparticles into in a polymer generated from the glycerin, and were characterized using FTIR.ATR, WAXD and SAXS techniques. In addition, the magnetic force and the oil removal capability of these materials were also studied. The results are encouraging because nano composites were obtained which possess magnetic forces larger than for pure maghemite. Furthermore, this nano composite is able to remove a petroleum mass around 300% larger than the used mass of the composite, which means that the composite may be important for avoiding environmental disasters owing to the oil spill on the water.

In this document the initiative of the program of environmental improvement of the Tlalpan Delegation of Mexico City is presented, as a pilot example within the national efforts in the matter of possible diminution of GEG emissions. The premise of the Tlalpan Program is the following one: The projects that will be successful in the global scope will be those that entail local benefits. With base in this, one has focused in activities that simultaneously offer local economic benefits and global results of GEG reduction. [Spanish] Mexico contribuye con cerca del 2% de las emisiones mundiales de gases de efecto invernadero (GEI), es el decimotercer pais con mayores emisiones de bioxido de carbono en el mundo. En este documento se presenta la iniciativa del programa de mejoramiento ambiental de la Delegacion Tlalpan, de Mexico D. F. como un ejemplo piloto dentro de los esfuerzos nacionales en materia de posible disminucion de emisiones de GEI. La premisa del Programa Tlalpan es la siguiente: Los proyectos que tendran exito en el ambito global seran los que conllevan beneficios locales. Con base en esto, se ha enfocado en actividades que simultaneamente ofrecen beneficios economicos locales y resultados globales de reduccion de GEI.

    This paper presents the historical development of the electric auto supply systems and cogeneration in Mexico since 1942 to 1995 with the understanding that these are clearly differentiated and defined since 1992. Though it is not, but until 1994 when the first ex profeso permit for cogeneration was granted. It also develops a short prospective vision of the cogeneration in our country, as well as the fuel consumption employed by auto- supply systems during 1993. The pollution emissions to the environment are also analyzed and with it the environmental impact of these electric systems in this year. [Espanol] Se presenta el desarrollo historico de los sistemas de autoabastecimiento electrico y cogeneracion en Mexico desde 1942 a 1995, en el entendido que estos se diferencian y definen claramente desde 1992. Es, sin embargo, hasta 1994 cuando se otorgo el primer permiso ex profeso de cogeneracion. Se desarrolla, ademas, una breve vision prospectiva de la cogeneracion en nuestro pais. Asimismo, se analiza el consumo de combustibles empleados por los sistemas de autoabastecimiento en 1993. Se estiman las emisiones contaminantes a la atmosfera y con ello se valora el impacto ambiental de estos sistemas electricos en ese ano.

    Full Text Available The Rio+20 United Nations Conference on Sustainable Development represents a crucial opportunity to place environmental health at the forefront of the sustainable development agenda. Billions of people living in low- and middle-income countries continue to be afflicted by preventable diseases due to modifiable environmental exposures, causing needless suffering and perpetuating a cycle of poverty. Current processes of economic development, while alleviating many social and health problems, are increasingly linked to environmental health threats, ranging from air pollution and physical inactivity to global climate change. Sustainable development practices attempt to reduce environmental impacts and should, in theory, reduce adverse environmental health consequences compared to traditional development. Yet these efforts could also result in unintended harm and impaired economic development if the new "Green Economy" is not carefully assessed for adverse environmental and occupational health impacts. The environmental health community has an essential role to play in underscoring these relationships as international leaders gather to craft sustainable development policies.A Conferência da ONU Rio +20 sobre desenvolvimento sustentável representa uma oportunidade crucial para colocar a saúde ambiental à frente da agenda de desenvolvimento sustentável. Bilhões de pessoas que vivem em países de baixa e média renda continuarão a ser afligidas por doenças evitáveis devido a exposições ambientais modificáveis causando sofrimento desnecessário e perpetuando um ciclo de pobreza. Processos de desenvolvimento econômico atuais, enquanto aliviam muitos problemas de saúde e sociais, estão cada vez mais ligados a ameaças de saúde ambiental, abrangendo desde poluição do ar e inatividade física até mudanças climáticas globais.

    The ICLEA project includes several annually laminated (varved) lake records from the southern Baltic lowlands for detailed climatic and environmental reconstructions. Continuous geochemical records have been obtained by XRF scanning and reveal the dominant depositional processes of the German lake Tiefer See and the Polish lakes Głęboczek, Czechowskie and Jelonek. Each lake record has been independently dated by means of varve counting, AMS 14C dating and tephrochronology. The unprecedented age control allows accurate age correlation of individual lake records even over large distances. The detailed stratigraphy is used in combination with micro-XRF core scanning records to link depositional variability with past environmental and climatic changes. However, in each lake the major sedimentological transitions are reflected by different geochemical elements due to the different depositional conditions. Here we present a statistical concept for XRF core scanning data to evaluate the timing and frequency of the most prominent sedimentological transitions of the Early to Mid Holocene. Preliminary results reveal that depositional conditions prevail over relatively long periods (102-103 yrs) between the Younger Dryas and ~6000 yrs. The sedimentological transitions during this period are associated to regional climatic changes in the southern Baltic lowlands during this period. After ~6000 yrs BP, depositional conditions vary at a much higher frequency (10-102 yrs), which are associated with a stronger local and lake internal environmental variability. Ongoing research focuses on a multi-proxy approach to further constrain possible links between depositional changes recorded in these varved lacustrine sediments with Early- to Mid-Holocene climatic and environmental variations. This study is a contribution to the Virtual Institute of Integrated Climate and Landscape Evolution Analysis - ICLEA - of the Helmholtz Association.

    Quantification of the initial rates of environmental reactions at the mineral/water interface is a fundamental prerequisite to determining reaction mechanisms and contaminant transport modeling and predicting environmental risk. Until recently, experimental techniques with adequate time resolution and elemental sensitivity to measure initial rates of the wide variety of environmental reactions were quite limited. Techniques such as electron paramagnetic resonance and Fourier transform infrared spectroscopies suffer from limited elemental specificity and poor sensitivity to inorganic elements, respectively. Ex situ analysis of batch and stirred-flow systems provides high elemental sensitivity; however, their time resolution is inadequate to characterize rapid environmental reactions. Here we apply quick-scanning x-ray absorption spectroscopy (Q-XAS), at sub-second time-scales, to measure the initial oxidation rate of As(III) to As(V) by hydrous manganese(IV) oxide. Using Q-XAS, As(III) and As(V) concentrations were determined every 0.98 s in batch reactions. The initial apparent As(III) depletion rate constants (t layered-double hydroxide minerals), or almost any other reaction occurring in aqueous media that can be measured using x-ray absorption spectroscopy.

    Somatic embryogenesis (SE) is an important biotechnological technique used for the propagation of many pine species in vitro. However, in bog pine, one of the most endangered tree species in the Czech Republic, limitations were observed, which negatively influenced the development and further germination of somatic embryos. Although initiation frequency was very low-0.95 %, all obtained cell lines were subjected to maturation. The best responding cell line (BC1) was used and subjected to six different variants of the maturation media. The media on which the highest number of early-precotyledonary/cotyledonary somatic embryos was formed was supplemented with 121 μM abscisic acid (ABA) and with 6 % maltose. In the end of maturation experiments, different abnormalities in formation of somatic embryos were observed. For visualization and identification of abnormalities in meristem development during proliferation and maturation processes, the environmental scanning electron microscope was used. In comparison to the classical light microscope, the non-commercial environmental scanning electron microscope AQUASEM II has been found as a very useful tool for the quick recognition of apical meristem disruption and abnormal development. To our knowledge, this is the first report discussing somatic embryogenesis in bog pine. Based on this observation, the cultivation procedure could be enhanced and the method for SE of bog pine optimized.

    Full Text Available Embora as crises militares continuem a ser uma uma preocupação maior para toda a humanidade, é claro que problemas continuados, tais como a disparidade entre ricos e pobres, entre as nações e internamente às sociedades, e outras formas de violação de direitos humanos e de agressão ambiental, em níveis regional e global, ameaçam o futuro da civilização na Terra. A qualidade de vida nos países menos desenvolvidos permanece sem melhorias e, ao mesmo tempo, mergulha vertiginosamente nos países industrializados. Medidas urgentes se fazem necessárias e reclamam um esforço cooperativo entre países mais e menos desenvolvidos em projetos de longo alcance em educação, saúde, agricultura sustentável e suprimento de energia. Sem dúvida, o problema populacional é igualmente fonte de grande preocupação. Falamos não apenas de aspectos quantitativos, mas, principalmente, de aspectos qualitativos. Embora haja instrumentos científicos e tecnológicos para corrigir essas perversões da civilização moderna, um esforço concentrado de todas as nações do mundo em direção à paz, nas suas várias dimensões, é absolutamente necessário.Although military crises continue to be a major concern for all of mankind, it is clear that ongoing problems such as disparities between rich and poor, among nations and within societies, other forms of violation of human rights and regional and global environmental aggression jeopardize the future of civilization on Earth. Quality of life continues to defy improvement in the less developed countries and at the same time plunges dizzily in the industrialized countries. Such issues call for a cooperative effort, bringing developed and less developed nations together in long-range projects in education, health, sustainable agriculture and energy supply. Clearly, the population problem is of equal concern. We are talking not only of quantitative aspects, but mainly of qualitative ones. Although there are

    We have designed, fabricated, and tested a compact gas-phase reactor for performing in situ soft x-ray scanning transmission x-ray microscopy (STXM) measurements. The reactor accommodates many gas atmospheres, including reactive or corrosive gasses, but was designed specically to address the needs of measurements under water vapor. An on-board sensor measures the relative humidity and temperature inside the reactor, minimizing uncertainties associated with measuring these quantities outside the instrument. The reactor mounts directly to the existing sample holder used in the majority of STXM instruments around the world and installs with minimal instrument reconguration. Using the reactor contributes over 85% less additional absorption compared to lling the STXM chamber with process gas, and results in much more stable imaging conditions. The reactor is in use at the STXM instruments at beamlines 11.0.2 and 5.3.2.2 at the Advanced Light Source.

    Environmental contaminants from wastewater and industrial or agricultural areas are known to have adverse effects on development, reproduction, and metabolism. However, reliable assessment of environmental contaminant impact at low (i.e., ambient) concentrations using genomics and transcriptomics approaches has proven challenging. A goldfish model was used to investigate the effects of aquatic pollutant exposure in vivo by means of quantitative nuclear magnetic resonance metabolomics in multiple organs to elucidate a system-wide response. Animals were exposed to 4,4'-isopropylidenediphenol (Bisphenol-A, BPA), di-(2-ethylhexyl)-phthalate (DEHP), and nonylphenol (NP). Metabolite-specific spectral analysis combined with pathway-driven bioinformatics indicated changes in energy and lipid metabolism in liver following exposure to individual contaminants and a tertiary mixture. A dissimilar response in testis exposed to DEHP and mixture indicates disrupted AMPK and cAMP signaling. Uniquely, our observations (1) suggest that exposure to a contaminant mixture is characterized by a stress response not predicted from exposure to individual contaminants, even in the absence of other phenotypic features and (2) demonstrate the sensitivity of metabolomics in risk-assessment of environmental toxicant mixtures at ambient concentrations by detecting early stage metabolic dysregulation. These findings have general applicability in the assessment of "benign" compound mixtures in environmental and pharmaceutical development.

El paisaje visual considera la estética y la capacidad de percepción por un observador. Para evaluar un paisaje existen diferentes métodos y procedimientos; aquí se propone un método mixto con valoración directa de subjetividad representativa y análisis posterior indirecto con análisis de componentes principales. El método propuesto intenta mejorar el problema de la subjetividad con grupos de evaluadores cuya opinión global sea representativa y es valorado con instrumentos que contienen listas de adjetivos con expresión numérica que facilita su procesamiento. En el análisis de componentes principales sí participan paneles de expertos. La técnica de valoración del paisaje es el análisis de preferencias, que parte aceptando que el valor de un paisaje está en función del número de individuos que le prefieren. También se describe un método para valorar la fragilidad del paisaje, que integrado a la valoración permite aplicar criterios de preservación y conservación. Una evaluación equivaldrá a una fotografía instantánea, que podrá ser comparada con una fotografía homóloga del futuro. Esto permitirá cuantificar las pérdidas (o ganancias de paisajes valiosos, sus agentes destructivos y sus medidas mitigantes. El ciudadano promedio está, por diferentes motivos, internalizando cada vez más una suerte de "conciencia ambiental" que redunda en una novedosa valorización de los espacios naturales y sus ecosistemas. Esto explica la creciente resistencia ciudadana a perder espacios de alto valor turístico, paisajístico y recreacional.

    This paper analyzes an 8-month time series (November 2005 to June 2006) of underwater noise recorded at the mouth of the Amundsen Gulf in the marginal ice zone of the western Canadian Arctic when the area was >90% ice covered. The time-series of the ambient noise component was computed using an algorithm that filtered out transient acoustic events from 7-min hourly recordings of total ocean noise over a [0-4.1] kHz frequency band. Under-ice ambient noise did not respond to thermal changes, but showed consistent correlations with large-scale regional ice drift, wind speed, and measured currents in upper water column. The correlation of ambient noise with ice drift peaked for locations at ranges of ~300 km off the mouth of the Amundsen Gulf. These locations are within the multi-year ice plume that extends westerly along the coast in the Eastern Beaufort Sea due to the large Beaufort Gyre circulation. These results reveal that ambient noise in Eastern Beaufort Sea in winter is mainly controlled by the same meteorological and oceanographic forcing processes that drive the ice drift and the large-scale circulation in this part of the Arctic Ocean.

    Full Text Available Currently, in the Bologna context, university teaching methods focus on the student and on a learning experience based on practical methods. Under the guidance of teachers, students in the second year of the first Environmental Health Course at the Polytechnic Institute of Beja have designed and developed the following nine community intervention projects relating to environmental health: dangerous products (mercury; habitability and geriatrics; health education and the environment; drinking water; information and communication in environmental health; efficient use of resources in public buildings; child development in outdoor spaces; and allergenic factors in housing. This pedagogical action takes place over three semesters, corresponding to the three distinct phases: design, implementation and evaluation / dissemination. To ensure the viability of the projects, each group of three students has established partnerships with various entities, such as city and parish councils, hospitals, schools, consumer cooperatives, companies dealing with hazardous waste, the Youth Institute and other commercial enterprises. Although it has not been possible to evaluate the whole project, preliminary results suggest that the planned activities have been very successful, with health benefits for the people involved, through environmental improvements or an increase in empowerment. It was also possible to achieve economic gains and contribute to the conservation of the environment. The students were able to gain skills and knowledge in a teaching model characterized by the absence of lectures in which students, assisted by teachers, take decisions and independent action, simulating a real context of professional practice. This experience suggests that, by utilizing the Bologna method, the polytechnic institutions may improve their real contribution to the health of communities.Actualmente y en el marco del Plan de Bolonia, las actividades docentes

    In situ high-temperature healing of cracks in composites made of glass and vanadium boride (VB) particles was observed using an environmental scanning electron microscope equipped with a high-temperature chamber (HT-ESEM). HT-ESEM is an adequate tool for studying the self-healing property of these materials. The change in crack length as a function of redox atmospheric conditions is reported. No self-healing behaviour was observed under reducing conditions, while a complete and rapid healing of the cracks was measured under oxidizing conditions. HT-ESEM image analyses enabled the monitoring of the healing effect. The self-healing mechanism was identified as a consequence of the VB active particles oxidation and subsequent pouring of fluid oxides into the cracks. These innovative composites offer an interesting potential in the domain of solid oxide fuel cell sealants.

    Proteus mirabilis is a common cause of catheter-associated urinary tract infections and frequently leads to blockage of catheters due to crystalline biofilm formation. Scanning electron microscopy (SEM) has proven to be a valuable tool in the study of these unusual biofilms, but entails laborious sample preparation that can introduce artefacts, undermining the investigation of biofilm development. In contrast, environmental scanning electron microscopy (ESEM) permits imaging of unprocessed, fully hydrated samples, which may provide much insight into the development of P. mirabilis biofilms. Here, we evaluate the utility of ESEM for the study of P. mirabilis crystalline biofilms in situ, on urinary catheters. In doing so, we compare this to commonly used conventional SEM approaches for sample preparation and imaging. Overall, ESEM provided excellent resolution of biofilms formed on urinary catheters and revealed structures not observed in standard SEM imaging or previously described in other studies of these biofilms. In addition, we show that energy-dispersive X-ray spectroscopy (EDS) may be employed in conjunction with ESEM to provide information regarding the elemental composition of crystalline structures and demonstrate the potential for ESEM in combination with EDS to constitute a useful tool in exploring the mechanisms underpinning crystalline biofilm formation.

    Small vertebrate model organisms have recently gained popularity as attractive experimental models that enhance our understanding of human tissue and organ development. Laser microsurgery on zebrafish larvae combined with Scanning Electron Microscopy (SEM) imaging can in particular provide accelerated insights into the tissue regeneration phenomena. Conventional SEM exposes, however, specimens to high vacuum environments, and often requires laborintensive and time-consuming pretreatments and manual positioning. Moreover, there are virtually no technologies available that can quickly immobilize the zebrafish larvae for high definition SEM imaging. This work describes the proof-of-concept design and validation of a microfluidic chip-based system for immobilizing zebrafish larvae and it's interfacing with Environmental Scanning Electron Microscope (ESEM) imaging. The Lab-on-a-Chip (LOC) device was fabricated using a high-speed infrared laser micromachining and consists of a reservoir with multiple semispherical microwells, which hold the yolk of zebrafish larvae, and drain channels that allow removing excess of medium during SEM imaging. Paper filter is used to actuate the chip and immobilization of the larvae by gentle suction that occurs during water drainage. The trapping region allows multiple specimens to be positioned on the chip. The device is then inserted directly inside the ESEM and imaged in a near 100% humidity atmosphere. This facilitates ESEM imaging of untreated biological samples.

    The presence and levels of flame retardants (FRs), such as polybrominated diphenyl ethers (PBDEs) and organophosphate flame retardants (PFRs), was determined in textile home furnishings, such as carpets and curtains from stores in Belgium. A comprehensive characterisation of FRs in textile was done by ambient high resolution mass spectrometry (qualitative screening), gas chromatography-mass spectrometry (GC-MS) (quantitation), and environmental forensic microscopy (surface distribution). Ambient ionisation coupled to a time-of-flight (TOF) high resolution mass spectrometer (direct probe-TOF-MS) was investigated for the rapid screening of FRs. Direct probe-TOF-MS proved to be useful for a first screening step of textiles to detect FRs below the levels required to impart flame retardancy and to reduce, in this way, the number of samples for further quantitative analysis. Samples were analysed by GC-MS to confirm the results obtained by ambient mass spectrometry and to obtain quantitative information. The levels of PBDEs and PFRs were typically too low to impart flame retardancy. Only high levels of BDE-209 (11-18% by weight) were discovered and investigated in localised hotspots by employing forensic microscopy techniques. Most of the samples were made of polymeric materials known to be inherently flame retarded to some extent, so it is likely that other alternative and halogen-free FR treatments/solutions are preferred for the textiles on the Belgian market.

It seeks to demonstrate that, despite being a reference in urban planning, Curitiba is no exception to the pattern of most Latin American cities, where predominate the socio-spatial segregation and environmental degradation. This pattern is due to the production of the city according to the logic of capitalism, which expels to inappropriate areas that portion of the population whose income does not allow to pay the costs of a good location. Given that in Latin American urban poverty is rising, and the city being structured based on market laws, it seeks to demonstrate that there is a trend of risk urbanism to consolidate itself as a prevailing practice.Este trabajo reflexiona sobre el concepto de urbanismo de riesgo. Al mirar la ciudad de Curitiba, en Paraná, Brasil, el texto analiza la relación entre las ocupaciones irregulares, la pobreza urbana y la degradación del medio ambiente. A pesar de constituirse en referencia de planificación urbana, Curitiba no es una excepción al patrón de las ciudades de América Latina, dominadas por la segregación socioespacial y la degradación del medio ambiente. Este patrón es resultado de la producción de la ciudad según la lógica capitalista, que expulsa para zonas inadecuadas a la población cuyos ingresos no cubren los costos de una buena ubicación. Dado que en América Latina la pobreza urbana está creciendo y la ciudad se estructura a partir de las leyes del mercado, el trabajo pretende demostrar que existe una tendencia hacia la consolidación del urbanismo de riesgo como práctica predominante.Abstract:Curitiba, Parana, Brazil, the text discusses the relationship between irregular occupations, urbanpoverty and environmental degradation.

    Since 2000 PETROBRAS adopted strategies and actions to establish excellence in Environmental Management and Operational Safety - PEGASO, having invested around 6.1 billions of reais in the last four years to reduce emissions, residues, effluents, and to improve prevention and accident control in its units. In this context, PETROBRAS Research and Development Center has been expanding knowledge about the ecosystems where the company operates, providing essential information to evaluate viability and sustainability on its enterprises, as well as for environmental licensing. Reinforcing its corporative strategy, it was created in 2002 the Environmental Assessment and Monitoring Section, a group that counts nowadays with 48 professionals. This group develops technology and methodology for monitoring in social and environmental context for the petroleum industry, gas and energy, evaluating the impacts of PETROBRAS activities and products life cycle, contributing for reduction of negative effects and to improve the company's environmental management. The research areas are: land, coastal and marine ecosystems monitoring, atmospheric monitoring and air quality, environmental chemistry, ecotoxicology, social and economic evaluation and environmental damage valuation. Working partnerships with the scientific community established several contacts with Brazilian and international universities. Among these various projects related to activities in the Brazilian offshore we present some aspects of the project Campos Basin Deep Sea Environmental Monitoring. (author)

    Some new pipelines undertakings aim to establish connection between gas provinces in the Southeast and consumers in the Northeast of Brazil, in order to supply medium consuming centers and regions with minor potential of development. Consulting companies are carrying out Environmental Assessments studies and among them is the Risk Analyses of these pipeline transmission systems, in order to receive environmental permits by IBAMA, the Federal Brazilian Environmental Agency. In addition, existing interstate pipeline systems which are under IBAMA regulation will also require the same attention. For the purpose of defining a Pipeline Risk Analysis Protocol with methodology and risk criteria, with minimum risk analysis information on a comprehensive process, it has been decided for a 'tour de force' formed by experts from IBAMA and PETROBRAS engineers. The risk assessment protocol is focus on the risk to communities in the neighborhood of these pipelines and on the potential damage to the environment near and far from the ROW. The joined work ended up in two protocols, which attempt to provide environmental license permits for oil pipeline and gas pipelines with minimum contents for risk analysis studies. Another aspect is the environmental risk that has been focused on the contingency plan approach, since there are no consolidated environmental risk criteria for application as a common worldwide sense. The environmental risk mapping - MARA methodology will indicate areas with potential to be affected by leakages along a pipeline system. (author)

    The Brazilian electric energy matrix is mostly renewable. According to the Generation Information Base (BIG) of the Brazilian Electricity Regulatory Agency (ANEEL), hydroelectricity is responsible for 67.31% of the country's energy. The additional generation comes mostly from fossil fuels, whose use is questioned when it comes to environmental quality and climate change. Despite its abundance, hydroelectric power generation has physical, socioeconomic and environmental limitations. Thus, it is essential to develop alternative technologies, providing security in the supply of electric energy and the maintenance of a clean matrix. Among the alternative technologies available, wind power is the one that has been gaining prominence, domestically and internationally speaking. In the last auction of renewable sources held in August 2010 in Brazil, the energy produced by the plants of sugarcane bagasse (biomass) was traded at an average of R$ 144.20 MWh; wind energy, which was the cheapest, was traded at R$ 130.86, and the energy from small hydropower plants (PCH), at R$ 141.93 MWh. The wind power plants accounted for 70% of the auction, which resulted in a plan for increasing its installed capacity by fivefold, by the year 2013. Brazil has great potential to be explored (estimated 143,000 MW), yet despite being appealing, wind energy still face some challenges. One of them is due to the fact that most potential areas for such energy are found in permanently preservation areas and areas considered national assets, subject to special protection measures. This study aims to investigate whether the regulatory, legal and environmental issues are considered an obstacle to an effective inclusion of wind power generation in Brazil. The study examines the process of environmental licensing of wind power plants, especially those established in permanently preservation areas (APPs) and Coastal Areas. The research methodology consisted of normative framework, judicial decisions

    Full Text Available Dyed natural rubber (NR and styrene butadiene rubber (SBR, designed for outdoor applications, were exposed to an accelerated artificial aging in xenon light. The aging results in the deterioration of the exposed surface material properties. The ability of dyed polymers to withstand prolonged sunlight exposure without fading or undergoing any physical deterioration is largely determined not only by the photochemical characteristics of the absorbing dyestuff itself but also by the polymer structure and fillers. Results obtained by laser mass spectrometry, UV-visible spectroscopy, and environmental scanning electron microscopy indicate that dyed filled NR and SBR samples behave differently during the photo-oxidation. The fading of the dyed polymers was found to be promoted in the NR sample. This can be correlated with LDI-FTICRMS results, which show the absence of [M-H]− orange pigment pseudomolecular ion and also its fragment ions after aging. This is confirmed by both EDX and UV/Vis spectroscopy. EDX analysis indicates a concentration of chlorine atoms, which can be considered as a marker of orange pigment or its degradation products, only at the surface of SBR flooring after aging. Reactivity of radicals formed during flooring aging has been studied and seems to greatly affect the behavior of such organic pigments.

    Airborne activity levels of uranium and thorium series were measured in the vicinity (1.1 km) of a uranium (UF4) processing plant, located in Malvési, south of France. Regarding its impact on the environment, this facility is characterized by its routine atmospheric releases of uranium and by the emission of radionuclide-labelled particles from a storage pond filled with waste water or that contain dried sludge characterized by traces of plutonium and thorium ((230)Th). This study was performed during a whole year (November 2009-November 2010) and based on weekly aerosol sampling. Thanks to ICP-MS results, it was possible to perform investigations of uranium and thorium decay product concentration in the air. The number of aerosol filters sampled (50) was sufficient to establish a relationship between airborne radionuclide variations and the wind conditions. As expected, the more the time spent in the plume, the higher the ambient levels. The respective contributions of atmospheric releases and resuspension from local soil and waste ponds on ambient dust load and uranium-bearing aerosols were estimated. Two shutdown periods dedicated to facility servicing made it possible to estimate the resuspension contribution and to specify its origin (local or regional) according to the wind direction and remote background concentration. Airborne uranium mainly comes from the emission stack and, to a minor extent (∼20%), from wind resuspension of soil particles from the surrounding fields and areas devoted to waste storage. Moreover, weighed activity levels were clearly higher during operational periods than for shutdown periods.

    The methodology for a Strategic Environmental Evaluation of Natural Gas - SEA/NG incorporates within the analysis of the project the socio-cultural, economic, energetic and environmental implications of the transformations, due to the adoption of natural gas, in the area of influence of gas pipelines and gas-powered thermo-electric plants. It was based on the case study of a gas pipeline planned to reach the city of Dourados from Campo Grande, capital of the Brazilian State of Mato Grosso do Sul, which implied the construction of a thermoelectric plant in Dourados. The SEA/NG: 1. Defines the best alternative track for gas pipelines; 2. Proposes location alternatives for gas-powered thermo-electric plants; 3. Evaluates the cumulative and synergic effects of human activities in the socio-environmental aspects; 4. Studies the dynamics of regional development; 4. Supports urban planning decisions in cities housing gas-powered thermo-electric plants; 5. Proposes a System of Analysis and Environmental Monitoring for Natural Gas. Qualitative-quantitative matrixes were used to evaluate the cumulative and synergic effects of the adoption of natural gas within the regional energy matrix, determine the best alternative track for the gas pipeline proposed from Campo Grande to Dourados, and to identify the best location for a gas-powered thermo-electric plant. The matrixes integrated the areas of geology, hydrology, ecology and socio-economics issues both in the phases of construction and operation of the pipeline. Diagrams and interactive conceptual models were also used to synthesize the principal components involved in the choice of the best gas pipeline alternative track. This project received financial grants from PETROBRAS, MSGAS, TBG and FINEP. (author)

    Full Text Available O artigo reflete sobre o contexto histórico e teórico de formação da educação ambiental brasileira a partir da perspectiva do que se convencionou chamar de educação ambiental crítica. Partindo de um referencial teórico-conceitual da ecologia política, da teoria crítica e do pensamento complexo, problematiza as origens e os desdobramentos político-culturais, os argumentos e movimentos sociais que formataram essa tendência pedagógica de marcante presença na realidade educacional e ambiental brasileira. À luz desses referenciais, o artigo revisa e sistematiza a produção pertinente a esse novo campo de conhecimento e ação e, nesse sentido, dialoga, por meio desta produção, com os pesquisadores, educadores, agentes públicos e de organizações da sociedade civil que, nas décadas recentes, se envolveram com práticas e reflexões sobre a relação entre sociedade, educação e meio ambiente no Brasil. Investiga, para tanto, o debate, a diferenciação e as disputas internas ao campo da educação ambiental no Brasil, o processo de constituição do socioambientalismo que se coloca em contraposição a outra tendência conservacionista de educação ambiental e a construção de uma crítica a uma educação para o desenvolvimento sustentável, proposto pela UNESCO e demais setores interessados na conservação do status quo e numa sustentabilidade orientada pelas forças do mercado. Destaca, assim, em uma perspectiva histórica, as matrizes filosóficas, as posições político-pedagógicas e as forças sociais que inspiraram a emergência da educação ambiental crítica assim como as contribuições decisivas que esse processo legou ao avanço ético e político das relações entre a educação, a sociedade e o meio ambiente no Brasil.The article is a reflection about the historical and theoretical contexts of the creation of environmental education in Brazil, from the perspective of what came to be called Critical

    Full Text Available Resumen: Los conceptos de intervención socioeducativa e intervención ambiental se han venido estudiando como dos aspectos diferentes, con ciertos puntos en común, pero con metodologías y estrategias separadas e inconexas. La finalidad de nuestro artículo es estudiar el proceso de evolución de ambos conceptos, para empezar a construir un modelo, centrado en lo que nosotros hemos querido denominar intervención educativa socioambiental, que aúne ambas intervenciones. Desde esta perspectiva toda intervención ambiental debe tener en cuenta los aspectos educativos y sociales porque las personas, los grupos y las comunidades son los afectados y beneficiarios de las transformaciones en el entorno físico y toda intervención socioeducativa debe contemplar los aspectos ambientales implicados, puesto que ésta siempre se desarrolla en un contexto socio-físico determinado. Abstract: The concepts of socio-educational and environmental interventions have been studied as two different fields, with some overlap, but with separated and unconnected methods and strategies. The purpose of our article is to study the development of both concepts to build a model, focused on what we have named socio-environmental educational intervention, bringing together both concepts. From this perspective, every environmental intervention should take into account educational and social aspects as individuals, groups and communities are the beneficiaries and the ones affected by the changes in the physical environment and each socio-educational intervention should consider all environmental aspects involved, since it always take place in a certain socio physical context.

    The energy and fuel obtaining process must be understand as a political concept and a socially built one. Such a process should be understood taking in account social impacts, environmental issues, land struggles. There are plenty of empirical examples able to identify flows, directions and speedy up enterprises when extracting matter and energy conversion within areas of high social and environmental sensibility. The infra-structure expansion over traditional people areas, high biodiversity mapped regions and environmental sensibility areas are expression of the capital intensive accumulation process and must be legitimated in one way or another. Simultaneously two way processes occur: in one hand the use of land, riverside areas and natural landscapes to generate electrical energy and fuel obtaining an in the other hand the abandon of original usage for the land. Specifically, in the Amazon rain forest area it is evident that the mentioned flows are supported by the natural wealthy. So, the analyses under a scientific approach, elaborating theories, demonstrations and occurrences documentation are necessary. Two preliminary expectations are posted by the article: 1) Discuss the implications due to the creation of energetic reserve areas over traditional people regions; 2) Produce a preliminary picture of demands over natural resources and respective social conflicts based on significant selected cases.

In this analysis, I report the use of qualitative methods and data in the study of the relationship between environmental exposures and human health. A primary search for peer-reviewed journal articles dated from 1991 through 2008 included the following three terms: qualitative, environ*, and health. Searches resulted in 3,155 records. Data were extracted and findings of articles analyzed to determine where and by whom qualitative environmental health research is conducted and published, the types of methods and analyses used in qualitative studies of environmental health, and the types of information qualitative data contribute to environmental health. The results highlight a diversity of disciplines and techniques among researchers who used qualitative methods to study environmental health. Nearly all of the studies identified increased scientific understanding of lay perceptions of environmental health exposures. This analysis demonstrates the potential of qualitative data to improve understanding of complex exposure pathways, including the influence of social factors on environmental health, and health outcomes.Pesquisa qualitativa usa dados não numéricos para entender opiniões, motivos e crenças sobre eventos e fenômenos.

    The Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS) in Mexico is a decentralized body, under the Secretaria de Energia whose main mission is to ensure that activities involving nuclear and radioactive materials as well as ionizing radiation sources are carried out with maximum security, considering the current technological developments. In order to monitor the levels of environmental radiation to which the population is exposed, the CNSNS has established a series of radiological monitoring programs that allow characterize the environmental radiation levels in each zone or region in the country; to identify the occurrence of natural or artificial radiological events, such as nuclear tests and accidents in radioactive or nuclear facilities. The National Automatic Network for Environmental Radiological Monitoring (RENAMORA) project was initiated with the support of the IAEA through MEX9/049 project and its purpose is to have a network of instruments that automatically and in real time, transmit information of the gamma radiological environmental status of the national territory and changes occurring in it. This network provides data such as the speed of ambient dose equivalent, temperature and humidity in different regions of the country. The network is composed of 92 stations that are distributed throughout the national territory. The structure of the stations has evolved since its inception, now allowing detection tasks, data transmission and managing them remotely from the main server, which is located in the CNSNS, which is performed a statistical dose for each monitoring station. Each monitoring station is formed in its current structure by a probe detection of gamma radiation, a communication module and associated electronics, a mini Web server DataGATE, a cellular modem and an interface converter.

    The European Environmental Liability Directive borrows from the US legislation the equivalency analysis tool. It is a tool to calculate the necessary remediation to return the environment to its baseline situation, as if it had not suffered the damage. The equivalence between damage and remediation can be estimated in terms of services (hectares of wetlands, for instance) or resources (trout, cork oaks), but under some circumstances the law also provides for welfare equivalency (generally expressed in monetary units). This articles introduces the equivalency tools, analyzes them in a cost-benefit analysis framework, and discuses some related issues, like the time treatment or the organization of a habitat banking system.

    Full Text Available The anisotropic structure of climatic space may cause significant (and to a large extent unappreciated non-evolutionary niche shifts. This can be seen mostly in the context of spatial transferability of ecological niche models. We explore this effect using a virtual species in the United States. We created a simple virtual species by postulating its fundamental niche as an ellipse in a two-dimensional realistic climatic space. The climatic combinations defined by the ellipse were projected in the geography of the United States and 2 regions of equal area were selected. The structure of niche in the 2 areas is compared. It is shown that the 2 regions have differently positioned subsets of the environmental space, which creates "shifts" in the realized niches despite the fact that no evolution and no biotic interactions are present. The most parsimonious hypothesis when ecological niche modeling reveals shifts in the realized niche is that environmental space is heterogeneous. Without considering differences in the structure of environmental space no speculation about niche evolution or the role of competitors should be attempted.La estructura anisotrópica del espacio climático puede causar desplazamientos significativos no evolutivos en los nichos de las especies. Este efecto poco apreciado en la literatura se manifiesta con gran claridad cuando se realizan transferencias espaciales de modelos de nicho ecológico. Se explora este efecto utilizando una especie virtual en los Estados Unidos. Se creó una especie virtual simplificada postulando su nicho fundamental en forma de una elipse en un espacio realista de 2 dimensiones. Las combinaciones climáticas definidas por la elipse se proyectaron en la geografía de los Estados Unidos y se seleccionaron 2 regiones de igual superficie espacial. Se compara la estructura del nicho en las 2 regiones, mostrando que estas 2 regiones espaciales presentan subconjuntos distintos del espacio de variables

    Full Text Available Recentemente, o conceito da pegada hídrica foi introduzido como um indicador importante de consumo de água para a humanidade. A pegada hídrica é definida como o volume total de água utilizado durante a produção de bens e serviços, bem como o consumo direto de água pelos seres humanos. A água não é consumida só diretamente mas também indiretamente, nos processos de produção. Portanto, o cálculo da pegada hídrica permite quantificar o total de água consumida ao longo da cadeia de fornecimento global. Esta revisão de literatura analisa o estado da arte da pegada hídrica desde a sua criação, no encontro internacional de especialista em comércio de água virtual realizado em dezembro de 2002 na Holanda, até os dias atuais. Os principais resultados encontrados na literatura consultada indicam consenso de que a pegada hídrica é capaz de monitorar o impacto humano sobre o meio ambiente. Além do mais, esta metodologia tem uma vasta gama de aplicações que pode ser empregada em escalas que vão desde um único produto, um processo, setor, individuo, cidades, até mesmo nações e todo o planeta.The concept of the water footprint has been recently introduced as an important indicator for human induced water consumption. The water footprint is defined as the total volume of water used during production and consumption of goods and services as well as direct water consumption by human beings. Water is not only consumed directly but also indirectly in production processes. Therefore, calculating the water footprint enables to quantify total water consumed along the whole global supply chain. This review surveys the state of the art on water footprint since the International Expert Meeting on Virtual Water Trade, held in Delft, The Netherlands, in December 2002, until current days. The major findings linked to the consulted literature indicated that the water footprint is suitable for monitoring the human impact on the environment

    This report is the original research work presented for the attainment of the author master degree and its main objective has been the resolution -by means of friendly programming- of some of the observed problems in the environmental radioactivity laboratory belonging to the Department of Radiological Surveillance and Environmental Radioactivity from CIEMAT. The software has been developed in Visual Basic for applications in Excel files and it solves by macro orders three of the detected problems: a) calculation of characteristic limits for the measurements of the beta total and beta rest activity concentrations according to standards MARLAP, ISO and UNE and the comparison of the three results b) Pb-210 and Po-210 decontamination factor determination in the ultra-low level Am-241 analysis in air samples by alpha spectrometry and c) comparison of two analytical techniques for measuring Pb-210 in air ( direct-by gamma spectrometry- and indirect -by radiochemical separation and alpha spectrometry). The organization processes of the different excel files implied in the subroutines, calculations and required formulae are explained graphically for its comprehension. The advantage of using this kind of programmes is based on their versatility and the ease for obtaining data that lately are required by tables that can be modified as time goes by and the laboratory gets more data with the special applications for describing a method (Pb-210 decontamination factors for americium analysis in air) or comparing temporal series of Pb-210 data analysed by different methods (Pb-210 in air).

    Throughout the historic evolution of the Brazilian legislation, including a brief analysis of the prevailing laws regarding the subject, this paper provides an ample vision of the civil and environmental liability in transport contracts, and, especially, in the transport of oil and gas through pipelines, discussing the present influence of environmental norms and the New Brazilian Civil Code. And what was brought to a conclusion is, if on one hand were kept the liability of the Sender (user company of the transportation service contracted with the Carrier) and Carrier (personal entity operator of the pipeline system), who respond jointly and regardless of fault for damages to third parties and the environment (extendible also to the owner of the product and to financial institutions that participate in some form in the contract), on the other hand the New Civil Code authorizes the National Petroleum Agency - ANP to rule the liabilities between the parties to the transport contract, providing greater safety to the system operators.

    In the heart of the Amazon forest, some 600 km from the city of Manaus, the Brazilian Oil Company - PETROBRAS - is developing the 'URUCU PROJECT'. Consisting on 3 oil and gas production fields and 3 natural gas processing plant, 2 huge pipelines crossing the dense Amazon forest and its rivers and going towards COARI - the Fluvial Terminal of Solimoes river. Then, vessels and ferries, loads LGN to the north region and oil to feed the Manaus refinery plant. In a near future natural gas pipelines will connect COARI to Manaus and URUCU to Porto Velho. The whole project will allow energy supply to the less developed and isolated region of Brazil, and brings relief for the local population, but represents one of the biggest challenges for the oil and gas industry in terms of environmental sustainability for projects in very sensitive areas. The paper concludes that it is viable to face such a challenges counting on an Environmental Management System tailored to fit the region peculiarities, including a high level of Preparedness and Response for oil incidents, and last but never least assuming a respectful attitude towards the Amazon and its people.

    Full Text Available The main target of the present article consists in basing from a specific context the place that occupies the environmental formation in the architecture students. In university context, education for sustainability implies a process that includes political decisions which open ways to generate opportunities for democratic participation in different stratums to define the institution strategies. At the same time education for sustainability requires a strong academic compromise to incorporate sustainability criteria in the education process. As a result, it urges to generate a behavior change that develops skills to create a proper sustainability environment. For all these reasons, the new educative law cannot ignore architecture career which encourages a professional who applies resources and strategies to build knowledge, develop values and acquire creative attitudes to improve the environment. El objetivo del presente artículo consiste en fundamentar desde un contexto específico el lugar que ocupa la formación ambiental en los estudiantes de arquitectura. En el ámbito universitario la educación para la soste¬nibilidad implica un proceso, que incluye decisiones políticas, que abran el camino para la generación de espacios necesarios para la participación democrática de los diversos estamentos para la definición de las estrategias propias de la institución, a la vez que requiere un fuerte compromiso docente para incorporar los criterios de sostenibilidad en los procesos de formación. Se necesita con urgencia generar cambios en la conducta para desarrollar capacidades que creen un ambiente propicio para la sostenibilidad. La carrera de Arquitectura no escapa a la actual reforma educativa que apuesta por un profesional que encamine el uso de recursos y estrategias, para llevar a cabo la construcción de conocimientos, el desarrollo de valores y la adquisición de actitudes creativas y comprometidas en la mejora del entorno.

    Clinch River - Environmental Restoration Program (CR-ERP) personnel and Tennessee Valley Authority (TVA) personnel conducted a study during the week of October 21-28, 1993, as described in the Statement of Work (SOW) document. The organisms specified for testing were larval fathead minnows, Pimephales promelas, and the daphnid, Ceriodaphnia dubia. Due to serious reproduction/embryo abortion problems with the TVA daphnid cultures, TVA conducted tests during this study period using only fathead minnows. A split sample test using daphnids only will be scheduled during 1994 as a substitute for this study period. Surface water samples were collected by TVA Field Engineering personnel from Poplar Creek Mile 2.9, Mile 4.3, and Mile 5.1 on October 20, 22, and 25. Samples were split and provided to the CR-ERP and TVA toxicology laboratories for testing. Exposure of test organisms to these samples resulted in no toxicity (survival or growth) in testing conducted by TVA.

    Full Text Available Entre os desafios atuais para a Saúde Pública está o de estruturar sistemas de indicadores que permitam monitorar as condições e tendências da sustentabilidade ambiental e de saúde. Neste artigo procuramos enfrentar esse desafio tendo como foco de análise os estados integrantes da Macrorregião Amazônia Legal, que desde a segunda metade do século XX vem sofrendo intensos processos de mudanças sócio-econômicas, ambientais, de saúde e bem-estar. Para a reunião e análise do conjunto de indicadores adotamos o modelo Forças Motrizes, Pressão, Situação, Exposição, Efeito e Ação (FMPSEEA proposto pela Organização Mundial da Saúde. Os resultados demonstram que, ao mesmo tempo em que as forças motrizes e pressões vêm contribuindo para o crescimento econômico e populacional, resultando em melhoras de indicadores tradicionais de saúde (redução da mortalidade infantil e aumento da expectativa de vida, são grandes as desigualdades sociais e econômicas e a sobreposição dos impactos na saúde da população, em um quadro bastante heterogêneo. Além disso, a situação ambiental também aponta para um modelo de desenvolvimento insustentável para as gerações presentes e futuras, exigindo respostas dos setores ambientais e de saúde à altura dos desafios colocados na atualidade.One of the challenges for public health is to build systems of indicators that allow monitoring current conditions and trends in environmental and health sustainability.

    Sugarcane bagasse is a residue from the sugarcane agroindustry. It is a biodegradable material, with low cost and presents affinity for organic compounds and toxic metals. In this work, the sugar cane bagasse combined with nanoparticles of magnetite was prepared and called magnetic biosorbent. The magnetite was synthesized by simultaneous precipitation by addition a solution of NaOH to the aqueous solution containing Fe{sup 2+} and Fe{sup 3+}. The material was characterized by scanning electron microscopy, Fourier Transformer Infrared Spectroscopy, thermogravimetric analysis, X-ray diffractometry and measurements of magnetization. The magnetic bio sorbent showed a high magnetization of saturation without hysteresis, behavior attributed to superparamagnetic materials. Variables of adsorption process of uranyl ions by magnetic bio sorbent in nitric solutions were investigated. The study of the equilibrium time indicated an increase in the adsorption in function of time. Smaller biosorbent particle sizes resulted in greater removals. The maximum removal occurred at pH 5. The increase of stirring speed of the solute plus biosorbent system favored the adsorption, reaching the equilibrium at 300 r.p.m. The increase of the bio sorbent dosage increased the removal, which became constant for doses above of 10 g.L{sup -1}. The equilibrium isotherm was verified according to the Langmuir and Freundlich adsorption isotherm models. The results correlated better to the Langmuir isotherm model, being found a value of maximum capacity of adsorption of 17 mg of U per g biosorbent. The same studies of adsorption were performed with the bagasse biosorbent in order to compare the results. (author)

This paper attempts to establish the effect of mission and vision, environmental scanning and the formality of the strategic planning process on the performance of SMEs. A quantitative research approach was pursued through a self-administered survey questionnaire. Descriptive statistics, correlation analysis and regression analysis were used to analyse the data. The main findings of the study suggest that, the mission and vision statements, environmental scanning and the formality of strategic planning have a positive effect on the performance of SMEs. The formality of strategic planning emerged as the factor with a stronger impact on SME performance than environmental scanning and mission and vision. The study provides some practical insights for SMEs for improving their performance in line with the identified effect of these three factors. Ultimately, improving their performance along these factors is set to reinforce SME sustainability and which will further stimulate their profitability.

    Detection of sulfur-oxidizing bacteria has largely been dependent on targeted gene sequencing technology or traditional cell cultivation, which usually takes from days to months to carry out. This clearly does not meet the requirements of analysis for time-sensitive samples and/or complicated environmental samples. Since energy-dispersive X-ray spectrometry (EDS) can be used to simultaneously detect multiple elements in a sample, including sulfur, with minimal sample treatment, this technology was applied to detect sulfur-oxidizing bacteria using their high sulfur content within the cell. This article describes the application of scanning electron microscopy imaging coupled with EDS mapping for quick detection of sulfur oxidizers in contaminated environmental water samples, with minimal sample handling. Scanning electron microscopy imaging revealed the existence of dense granules within the bacterial cells, while EDS identified large amounts of sulfur within them. EDS mapping localized the sulfur to these granules. Subsequent 16S rRNA gene sequencing showed that the bacteria detected in our samples belonged to the genus Chromatium, which are sulfur oxidizers. Thus, EDS mapping made it possible to identify sulfur oxidizers in environmental samples based on localized sulfur within their cells, within a short time (within 24 h of sampling). This technique has wide ranging applications for detection of sulfur bacteria in environmental water samples.

Se asegura el derecho a la información, todo habitante podrá obtener de las autoridades la información ambiental que administren y que no se encuentre contemplada legalmente como reservada. Los aspectos más importantes acerca de la educación ambiental y el desarrollo sostenible son ejes transversales de leyes de distinta jurisdicción, pero deberá bregarse por el cumplimiento y control de dichos principios, debido a las características con las que se percibe al derecho ambiental, de baja eficacia y eficiencia.Population environmental education must be conveyed in all educational levels, in order to contribute to a deep knowledge of environmental protection laws. These include contents about environmental education, but with scarce diffusion and low adhesion. If environmental education could force a detailed knowledge about regulations, its application could be demanded by community actions. Moreover, environmental education is considered in regulations as a fundamental tool for sustainable development. There is a profuse legislation in Argentina, with more than 3,000 legal instruments of different hierarchical order and jurisdictional level. Three argentine laws were studied and compared: Environmental General Law (national: Law 25,675; La Pampa Environmental Law (province order: Law 1,914; and Environmental Education Law of Buenos Aires (city order: Law 1,687. These laws regulate the incorporation of environmental education in formal system (public and private schools and institutions, for all levels: initial, primary, secondary and university studies, non formal system (extra-curricular activities and/or extension inside the institutions, and non formal education (by means of massive instruments of communication and information. Environmental education is considered as the basic tool to generate values, behavior and attitudes according to a balanced environment, tending to the preservation of natural resources and their sustainable

    Full Text Available A Área de Preservação Permanente (APP, principal área protegida instituída por norma jurídica no Brasil, foi criada pelo Código Florestal (Lei 4.771 em 1965. Por sua importância ecológica e fornecimento de bens e serviços ambientais ao homem, as APPs são reconhecidas por suas funções técnicas como áreas que devem ser preservadas. Muitas interpretações divergem do espírito da criação da Lei, seja pelo preciosismo linguístico ou pelo uso distorcido da hermenêutica O objetivo desta pesquisa foi analisar os principais pontos conflituosos do entendimento, da interpretação e da instituição das Áreas de Preservação Permanente. Concluiu-se que há, na literatura, pertinentes interpretações contrárias ao espírito da norma jurídica que institui as APPs; as APPs devem ser preservadas e, em caso de degradação, a legislação deixa patente que o passivo ambiental deve ser sanado; a intocabilidade das APPs não é inexorável, pois o CONAMA, em alguns casos, pode definir critérios para sua utilização; as intervenções em APP, permitidas por lei nos casos de utilidade pública, interesse social e atividade eventual e de baixo impacto ambiental necessitam de melhor regulamentação.The Permanent Preservation Area (PPA, the main protected area established by law in Brazil, was established by the Forest Code (Law 4771 in 1965. Due to their ecological importance and provision of environmental goods and services to humans, the PPAs are recognized for their technical functions as areas that should be preserved. Many of these differing interpretations of the spirit of the law occur depending on the language preciosism and the distorted use of hermeneutics. The objective of this research was to analyze the main points of conflict in the interpretation, understanding and establishment of permanent preservation areas. It was concluded that there is in literature interpretations contrary to the spirit of the legal rule establishing

    Full Text Available O artigo discute a necessidade da realização de um corte epistemológico que estabeleça o campo próprio de uma história ambiental, incluindo um repertório de métodos para a abordagem de diferentes processos, como as racionalidades econômicas, ecológicas e culturais do uso da natureza, assim como o regate de saberes e práticas tradicionais das diferentes culturas com seu entorno ecológico. São abordadas três vertentes para o estudo da história ambiental: a história epistemol ógica da complexidade ambiental, a hermenêutica das narrativas sobre as relações sociedade-natureza, a construção de identidades e as transformações sociais induzidas pelo movimento ambientalista.This article discusses the need to make an epistemological separation that establishes the very field of an environmental history, including a collection of methods for the approach to different processes, such as economic, ecological, and cultural rationalities of the usage of nature, as well as the rescue of traditional knowledge and practices from different cultures about their ecological surroundings. Three issues are discussed in the study of environmental history: the epistemological history of environmental complexity, the hermeneutics of narratives on society- nature relationship, the construction of identities, and the social transformations induced by the environmental movement.

    Full Text Available A degradação do meio ambiente no contexto atual é decorrente do uso desenfreado dos recursos naturais pela sociedade. Diante disso, o governo passou a exigir uma política mais responsável das organizações. As empresas passaram a adotar medidas de gestão ambiental, sistemas de gestão ambiental, que gerem benefícios tanto para a organização quanto para a natureza. O presente artigo tem como objetivo analisar a contabilidade ambiental como instrumento gerencial, visando o desempenho e a sustentabilidade ambiental. A metodologia adotada é um estudo de caso em um hospital, utilizando-se de uma entrevista semi- estrutura da com o responsável pela área ambiental da instituição. A trajetória metodológica divide-se em três fases, sendo a primeira: fundamentação teórica do meio ambiente, gestão ambiental, auditoria, contabilidade e controladoria ambiental. A segunda fase envolve o estudo de caso, onde são realizadas primeira mente as entrevistas com base em uma lista de verificação, divididas em critérios e subcritérios. Na terceira e última fase apresenta-se análise dos resultados; a sustentabilidade parcial e total, bem como o planejamento 5W2H. No final, como resultado da pesquisa, verificou-se uma sustentabilidade global de 70,83%, considerada “regular”. Existem pontos fortes e fracos na gestão do meio ambiente, mas no geral ela apenas cumpre com a legislação.The current environmental destruction is the result of the unlimited use of naturalresources by our society.

    Full Text Available A produção de biodiesel foi incentivada pelo desejo de se obter fontes energéticas de origem diferente do petróleo. Este processo, contudo, gera grandes quantidades de glicerina como subproduto. Assim, novas aplicações devem ser encontradas para esta glicerina evitando o colapso da cadeia nacional produtiva de glicerina animal. Uma aplicação mais nobre para esta glicerina, proveniente da indústria de biodiesel, é a produção de resinas alquídicas. Estas resinas podem ser utilizadas como matrizes de compósitos para recuperação de ambientes aquáticos impactados por acidentes de derrames de petróleo. Outra aplicação para estes materiais é na remoção e limpeza de águas produzidas e águas de refinaria, visando a atender a legislação ambiental. Neste trabalho, nanocompósitos espumados magnetizáveis foram preparados pela inserção de nanopartículas magnetizáveis em uma matriz de resina alquídica, obtida a partir da glicerina oriunda do óleo de mamona. Os materiais produzidos foram caracterizados por FTIR-ATR, DRX e SAXS. Além disso, a força magnética destes materiais foi estudada bem como a capacidade de remoção de petróleo derramado sobre água. Os resultados são animadores, pois demonstram a obtenção de um nanocompósito que possui força magnética relativa superior à da maguemita pura. Além disso, este nanocompósito é capaz de remover massas de petróleo cerca de 300% superiores às massas do material usado. Estes materiais, portanto, consistem em uma potencial ferramenta para a recuperação de ambientes aquáticos impactados por acidentes de derramamento de petróleo.The biodiesel production was encouraged since the entire world is looking for new energy sources. However, the biodiesel process produces large amounts of glycerin as byproduct. Therefore, innovative uses for this new glycerin source must be sought so as to avoid the collapse of the animal glycerin chain. In this context, the production

    Full Text Available Companies have been witnessing major changes in their environment and environmental models have been developed aiming to improve their strategic planning. The objective of this study was to examine the environmental approach adopted by companies within the Pulp and Paper, Metallurgical and Sugar and Alcohol sectors, in order to evaluate their environmental performances. The analysis was based on a matrix which relates managerial functions with a set of environmental approaches and performance indicators, classifying the company environmental performance as weak, moderate or strong. The managerial functions approached in this model are: Management (General, Legal Affairs, Finance, Human Resources and Purchasing; Product and Process Development; Production and Maintenance; and Marketing. The analyzed indicators include: international insertion; capital origin and location. The pulp and paper and metallurgical companies obtained average scores of 54.5 and 51.56 points, respectively, being classified as having a strong environmental performance. On the other hand, the sugar and alcohol companies obtained average score of 46 points, being classified as moderate in environmental performance. The high level of environmental performance of pulp and paper and metallurgical companies can be attributed to the following factors: larger international insertion, presence of foreign capital in controlling shares, performance in the international market and company location near large population centers. Pulp and paper and mainly sugar and alcohol companies are less efficient in meeting the requirements of the environmental legislation, particularly those related to the conformity of permanent protected areas and legal reserves.As empresas têm presenciado transformações amplas no ambiente em que estão inseridas e, com o intuito de auxiliar no planejamento estratégico das empresas, têm sido desenvolvidos modelos ambientais.

    This work presents the Agenda 21 Local construction process developed by PETROBRAS within the context of the 'De Olho no Ambiente' Program. This is an alternative for the sustainable development of reduced social inclusion communities located in the Company's areas of influence in the Amazon Region. Agenda 21 is a participative process that analyzes a country, state, municipal or community's actual situation, and plans its sustainable future. Its objective is to reach a new development paradigm, through the construction of an action plan focused on a future scenario desired by the local community, which takes into consideration the vulnerability and potential analysis of its socio-economical, cultural and environmental bases. PETROBRAS has introduced Agenda 21 Local in three riverside communities located in the Coari municipal, where the Solimoes Terminal (TESOL) is situated. This terminal receives and stores petroleum and gas from the Urucu Petroliferous Province, in the Amazonian State. In each location partnerships were signed with several governmental and civilian institutions during the implementation of the Agenda 21 Local Forum. Here each participant has the right to debate, which makes this a participative management process mechanism and an act of citizenship. (author)

    The wetting of rough honeycomb micrometrically scaled polymer substrates was studied. A very strong dependence of the apparent contact angle on the drop volume has been established experimentally. The environmental scanning electron microscopy study of the fine structure of the triple line is reported first. The triple line is not smooth and prefers grasping the polymer matrix over air holes. The precursor rim surrounding the drop has been observed. The revealed dependence of the apparent contact angle on the drop volume is explained by the transition between the pure Cassie and combined Wenzel-Cassie wetting regimes, which is induced by capillarity penetration of water into the holes of relief.

    The Brooklyn traffic real-time ambient pollutant penetration and environmental dispersion (B-TRAPPED) study was a multidisciplinary field research project that investigated the transport, dispersion, and infiltration processes of traffic emission particulate matter (PM) pollutants in a near-highway urban residential area. The urban PM transport, dispersion, and infiltration processes were described mathematically in a theoretical model that was constructed to develop the experimental objectives of the B-TRAPPED study. In the study, simultaneous and continuous time-series PM concentration and meteorological data collected at multiple outdoor and indoor monitoring locations were used to characterize both temporal and spatial patterns of the PM concentration movements within microscale distances (dispersion of PM; (3) studying the influence of meteorological variables on the transport, dispersion, and infiltration processes; (4) characterizing the relationships between the building parameters and the infiltration mechanisms; (5) establishing a cause-and-effect relationship between outdoor-released PM and indoor PM concentrations and identifying the dominant mechanisms involved in the infiltration process; (6) evaluating the effectiveness of a shelter-in-place area for protection against outdoor-released PM pollutants; and (7) understanding the predominant airflow and pollutant dispersion patterns within the neighborhood using wind tunnel and CFD simulations. The 10 papers in this first set of papers presenting the results from the B-TRAPPED study address these objectives. This paper describes the theoretical background and models representing the interrelated processes of transport, dispersion, and infiltration. The theoretical solution for the relationship between the time-dependent indoor PM concentration and the initial PM concentration at the outdoor source was obtained. The theoretical models and solutions helped us to identify important parameters in the

Finalmente, discute-se a participação relativa dos efeitos de ambiente e genéticos na correlação fenotípica.Since development of commercial varieties involves simultaneous selection for various traits, previous knowledge of their interrelationships may also be fundamental to the breeder as the strategies to be adopted. The objective of this research was to estimate phenotypic, additive genetic and environmental correlations for a number of traits of agronomic interest in carrot (Daucus carota L. cultivar Campinas, grown during the fall-winter and spring-summer seasons at the Experiment Station of Monte Alegre do Sul, Instituto Agronômico de Campinas (IAC, State of São Paulo, Brazil. This germplasm, originated from the "Seção de Hortaliças" (IAC, presents, besides a high level of resistance to Alternaria dauci, a large variation for root shape and a tendency to early bolting, stimulated by low temperatures and/or long photoperiods during the crop vegetative stage. Data were obtained by evaluating 102 half-sib progenies on a randomized block design experiment with four and three replications, respectively, for the fall-winter and spring-summer planting dates. Phenotypic (rF, additive genetic (rA and environmental (rE correlations were estimated by covariance analyses between pairs of characters, in both planting dates. The phenotypic and additive genetic correlations were negative only for pairs of characters involving percentage of early flowering (EF or percentage of defective roots, while the correlations were high (>0.5 for most of the pairs of characters in both planting dates. Selection for percentage of cylindric marketable roots will lead to reduction in EF as well as increases in marketable root yield and total root yield in both planting. This research further presents a discussion of the relative participation of environmental and genetic effects in the phenotypic correlation.

En Brasil estos estudios también han evolucionado en las últimas dos décadas, siendo importante para su delineación el trabajo del Grupo de Trabajo "Población y Medio Ambiente", de la Asociación Brasileña de Estudios Poblacionales, privilegiado foco difusor de estas preocupaciones en el país. En vista de esto, este artículo pretende reflexionar sobre el trabajo del grupo, con la expectativa de traer a la superficie algunos elementos acerca de los métodos, temas y problemáticas abordadas a lo largo de los años, en el sentido de localizar en que punto de este desarrollo se encuentra hoy la temática, y cuales son las perspectivas y los desafíos que se abren para el futuro.The social sciences were latecomers in the acceptance and incorporation of the environment into their respective research programs. Among them, Demography was perhaps the last to make this change, gradually incorporating population-environment questions. The debate has converged toward the growing incorporation of the spatial dimension, long present but not a defining issue of demographic studies, but which is central in the environmental discussion. The development of the field, though rapid and promising, has encountered difficulties inherent to interdisciplinary fields, occupying a place on the periphery of one science, at the interface with others. In Brazil, where these studies have also evolved over the last two decades, the work of the Working Group on Population and Environment of the Brazilian Association of Population Studies has been a key factor in disseminating this concern. In view of this, we seek to reflect on the production of this group to identify elements concerning the methods, themes and problematics treated over the years, in order to assess where this field is today, and what are its future perspectives and challenges.

    Full Text Available A educação ambiental crítica e emancipatória exige que os conhecimentos sejam apropriados, construídos, de forma dinâmica, coletiva, cooperativa, contínua, interdisciplinar, democrática e participativa, voltados para a construção de sociedades sustentáveis. Este artigo trata dos temas ambientais como temas geradores para a educação ambiental, inspirados na pedagogia Paulo Freire, para quem educar é um ato de conhecimento da realidade concreta, das situações vividas, um processo de aproximação crítica da própria realidade: compreender, refletir, criticar e agir são as ações pedagógicas pretendidas. Os temas geradores são, portanto, estratégias metodológicas de um processo de conscientização da realidade opressora vivida nas sociedades desiguais; são o ponto de partida para o processo de construção da descoberta, e, por emergir do saber popular, os temas geradores são extraídos da prática de vida dos educandos, substituindo os conteúdos tradicionais e buscados através da pesquisa do universo dos educandos. O caráter político da pedagogia freireana faz-se presente, de forma radical, nos temas geradores, isto é, temas geradores só são geradores de ação-reflexão-ação se forem carregados de conteúdos sociais e políticos com significado concreto para a vida dos educandos. Assim, as propostas educativas ambientais conscientizadoras podem tomar os temas ambientais locais como temas geradores desta ação conscientizadora, desde que estes temas contenham conteúdos socioambientais significativos para os educandos e sejam definidos coletiva e participativamente.The emancipating and critical environmental education demands that knowledge must be adequate, build up in a dynamic, collective, cooperating, continuous, interdisciplinary, democratic and participating way directed to the construction of self-maintaining societies.

    The Mexican transportation sector, as with that of many other countries, is characterized by basing its energy consumption in hydrocarbons (gasoline, diesel and LP gas). At the present times, this dependency has brought along a series of problems of environmental nature, which concentrate in a larger scale in the urban areas. Therefore, the study of the transportation sector as an energy consumer requires the institution of new terms where the constant to study (directly or indirectly) is the environmental variable, trying to correlate the proper sector activities, its development and the energy consumption with the environment. This paper`s objective is to know the actual situation of the transportation sector in the metropolitan area of Mexico City (MAMC) and its environmental impact. It is therefore an energy-environmental inventory energy-environmental focussed to the use of fuels in the transportation sector, whose environmental effect has a significant cost for the country. This paper has been divided in four parts. First, the importance of the sector as an energy consumer in the MAMC is characterized in aggregated form. Second, the main variables that affect the development of the sector to obtain the consumption in separated form as well as the base criteria for its development, obtaining a series of results that show the effect of the different modes and types of energy consumption. In the third part, reference is made to the environmental impact originated by the utilization of fossil fuels in the transportation sector, emphasizing in the transportation means that more heavily affect for the emission of pollutants. Finally a series of options are presented that allow finding an equilibrium among transportation, energy and environment. [Espanol] El sector transporte mexicano, como el de muchos otros paises se caracteriza por basar su consumo energetico en hidrocarburos (gasolina, diesel y gas licuado).

    Sulfur-oxidizing bacteria play important roles in global sulfur cycle. Sulfur bacteria detection has been largely dependent on targeted gene sequencing technology or traditional cell cultivation which usually takes from days to months to finish. This cannot meet the requirements of some time-sensitive samples and/or complicated environmental samples. Since Energy-Dispersive X-ray Spectrometry (EDS) can be used to simultaneously detect multiple elements including sulfur in a sample with minimal sample treatment, the technology was applied to detect sulfur bacteria through the high sulfur content in the bacteria cell. We report the application of SEM (scanning electron microscopy) imaging coupled with EDS mapping for direct and quick detection of sulfur oxidizer in contaminated environmental water samples. The presence of sulfur bacteria can be confirmed within 24 hours after sampling. Subsequent 16S RNA gene sequencing results found the bacteria detected had over 99% similarity to Chromatium Okenii, confirming the bacterium was a sulfur oxidizer. The developed technique made it possible to quickly detect sulfur oxidizer in environmental sample and could have wide applications in sulfur bacteria detection in environmental water samples.

    Lack of data regarding environmental matters in relation to the great majority of MSW landfills throughout Spanish territory makes it difficult to consider them suitable for exploitation or territorial expansion required for different activities demanded by society. The environmental risk of a landfill must be minimised with the help of environmental planning tools. One of these tools is based on the environmental diagnosis and characterisation of the areas affected by the solid waste deposit.. Diagnosis by means of quantifiable environmental indexes helped us in our work to determine the priorities for the environmental control of certain Spanish landfills. This diagnosis was used for creating the Observatory on Solid Waste Landfills, organized by ATEGRUS (Spanish Technical Association for Waste Management) in 2003 and presented at ATEGRUS 30th Annual conference on Controlled Landfills.

    Very highly porous (aerogel) silica films with refractive index in the range 1.006--1.05 (equivalent porosity 98.5--88%) were prepared by an ambient-pressure process. It was shown earlier using in situ ellipsometric imaging that the high porosity of these films was mainly attributable to the dilation or `springback` of the film during the final stage of drying. This finding was irrefutably reconfirmed by visually observing a `springback` of >500% using environmental scanning electron microscopy (ESEM). Ellipsometry and ESEM also established the near cent per cent reversibility of aerogel film deformation during solvent intake and drying. Film thickness profile measurements (near the drying line) for the aerogel, xerogel and pure solvent cases are presented from imaging ellipsometry. The thickness of these films (crack-free) were controlled in the range 0.1-3.5 {mu}m independent of refractive index.

    Full Text Available This work demonstrates that, for the materialization of the fundamental right to environment, it is necessary that the State intervenes in the Economic Order so as to implement environmental policies that redirect both private initiative and consumers to desirable practices. For such an aim, the efficiency of economic instruments is emphasized by means of the Environmental Tributary Law. Through tributes or concession of fiscal benefits it is possible to induce appropriate practices. This research confirms that the environmental tributary policies in Brazil should take the form of fiscal benefits, instruments considered more appropriate to discourage pollution and foment responsible environmental practices.Demonstra que para a concretização do direito fundamental ao meio ambiente é necessário que o Estado intervenha na Ordem Econômica a fim de implementar políticas ambientais que redirecionem a racionalidade da iniciativa privada e consumidores a práticas ambientalmente desejáveis. Para tal finalidade, enfatiza-se a eficiência dos instrumentos econômicos por intermédio dos institutos do Direito Tributário Ambiental. Por meio da instituição de tributos ou pela concessão de benefícios fiscais é possível a indução a práticas ambientalmente adequadas. Constata que a política tributária ambiental no Brasil deve ocorrer por intermédio de benefícios fiscais, instrumentos mais apropriados para desestimular a poluição e fomentar práticas ambientais responsáveis.

    Full Text Available A incorporação da vigilância ambiental no campo das políticas públicas de saúde é uma demanda relativamente recente no Brasil. Um dos principais desafios da vigilância ambiental em saúde é a definição do seu objeto e a especificidade de suas ações. O conceito ampliado de exposição, tratado não como um atributo da pessoa, mas do conjunto de relações complexas entre a sociedade e o ambiente, é central para a definição de indicadores e para a orientação da prática de vigilância ambiental. Entre as dificuldades encontradas para sua efetivação no Sistema Único de Saúde estão a necessidade de reestruturação das ações de vigilância em saúde e a formação de equipes multidisciplinares, com capacidade de diálogo com outros setores, além da construção de sistemas de informação capazes de auxiliar a análise de situações de saúde e a tomada de decisões. Nesse sentido, foi realizada uma revisão do objeto e conceitos da vigilância ambiental em saúde, bem como identificados os desafios para a sua implantação no Sistema Único de Saúde.The incorporation of environmental surveillance in the field of public health policies is a relatively recent demand in Brazil. One of the major challenges in environmental health surveillance is defining its object and the specificity of its practice.

    Based on an arrogant idea that nature would exclusively serve as a source for its own desires, the humanity has always developed an anthropocentric position in its relationship with nature. From the emergence of capitalism and Industrial Revolution, the economy assumes the position of the worst environmental destroyer. However, this conflict between economy and natural environment could not last anymore. Therefore, The appearance of an 'environmental consciousness' on international level had become something inevitable. From this new ecological mentality, countries started to develop a primal environmental legislation, witch culminated, into a process called 'Constitutionalization of environment protection'. In this framework, Brazil produced, in 1988, a Constitution that is considered one of the world's most modern in terms of natural resources protection, turning this subject into a constitutional principle and a fundamental right. This new perspective of environmental defense brought, invariably, many benefits to the maintaining of an ecologically balanced ecosystem. Finally, the world's ecological concept has also changed since industries started to note that environmental policies could generate more profits and turn them more competitive companies. (author)

    The purpose of the present work is to establish a methodology for assessing the sustainability of buildings in Mexico, which can be standardized and comparable with the rest of North America. For this purpose three building assessment systems in North America were first analyzed: (a) Leadership in Energy and Environmental Design (LEED), (b) Living Building Challenge (LBC); and (c) Energy Star for Buildings. In addition, the analysis included Spain's Green Building Council (GBCe), to have a different comparison point with the North American systems. The analysis of the four systems suggests the use of the Energy Star system due to the following reasons: 1) For all systems, the Energy Star system is the basis for comparison in terms of energy consumption and therefore emissions of greenhouse gases, 2) It is the system requiring the simplest description of the building (construction surface, occupancy and energy consumption) and does not require (unlike other systems) data on the location of the buildings, 3) For the LEED, LBC and GBCe systems, the evaluation must be performed by professionals accredited, while for the Energy Star certification is less restrictive A database of public buildings, managed by the Comision Nacional para el Uso Eficiente de la Energia (CONUEE), was used. It integrates a significant number of office buildings occupied by departments and agencies of the federal government in Mexico. This database holds information on annual energy consumption and area occupied. Such database was complemented with available information on Degree Day data provided by the Asociacion de Empresas para el Ahorro de Energia en la Edificacion (AEAEE); it allowed to include information on weather in the same terms as the proposed methodology by Energy Star system. From the analysis, some suggestions are presented below. First, it is suggested to strengthen the collection and integration of information related to commercial buildings in Mexico to implement a

    In environmental scanning electron microscopy applications in the kPa regime are of increasing interest for the investigation of wet and biological samples, because neither sample preparation nor extensive cooling are necessary. Unfortunately, the applications are limited by poor image quality. In this work the image quality at high pressures of a FEI Quanta 600 (field emission gun) and a FEI Quanta 200 (thermionic gun) is greatly improved by optimizing the pressure limiting system and the secondary electron (SE) detection system. The scattering of the primary electron beam strongly increases with pressure and thus the image quality vanishes. The key to high-image quality at high pressures is to reduce scattering as far as possible while maintaining ideal operation conditions for the SE-detector. The amount of scattering is reduced by reducing both the additional stagnation gas thickness (aSGT) and the environmental distance (ED). A new aperture holder is presented that significantly reduces the aSGT while maintaining the same field-of-view (FOV) as the original design. With this aperture holder it is also possible to make the aSGT even smaller at the expense of a smaller FOV. A new blade-shaped SE-detector is presented yielding better image quality than usual flat SE-detectors. The electrode of the new SE detector is positioned on the sample table, which allows the SE-detector to operate at ideal conditions regardless of pressure and ED.

Com base neste modelo, uma empresa submetida a pressões da estrutura da indústria busca uma performance tríplice (econômica, ambiental e social e, para tanto, precisa estabelecer condutas claramente sociais e ambientais, além da econômica. A pesquisa na indústria têxtil nordestina foi realizada em empresas representativas do setor e instaladas nos estados do Ceará, Paraíba, Pernambuco e Rio Grande do Norte, através de entrevistas diretas. O estudo analisa as empresas em função do porte e identifica perfis estratégicos de condutas ambientais e sociais, segundo uma escala definida como fraca, intermediária ou forte. Os resultados indicam uma predominância de empresas que adotam condutas fracas. Comparativamente, existe uma maior preocupação com a conduta ambiental que a social.

Based on the assumption that these firms have natural structural weaknesses and, as a consequence, intrinsic difficulties in investing in environmental assets, the paper suggests that a particular public policy, namely, business incubators, could contribute to overcoming these barriers and thus pave the way for environmental investments. Two important findings should be highlighted: a the neglect of the incubators investigated (and thus, of the nurtured firms with respect to environmental performance; b the absence of stimuli, from business incubators, for environmental investments. From the results, an important conclusion may be drawn: namely, that where weak patterns of environmental

Aplicando el método arqueológico, este artículo analiza la obra de la principal figura de la sociología ambiental, Riley E. Dunlap, representativa de la crisis de la especialidad. El individualismo metodológico, la preferencia por el uso de encuestas a población general, la falta de un marco teórico fuerte y de atención a factores estructurales e históricos, característicos del trabajo de Dunlap y sus seguidores, parecen ser las principales causas del bloqueo de la sociología ambiental, dada su enorme influencia en la disciplina.

This stagnation is due to inadequate theoretical and methodological reflection in the discipline. Applying the archaeological method, this article analyzes the work of the environmental sociologist Riley E. Dunlap, a prominent figure and a representative of the crisis of the discipline. Methodological individualism, the preference for the use of surveys of the general population, the lack of a strong theoretical frame, or of attention to structural and historical factors - all these are faults in the work of Dunlap and his followers. It is these faults that are arguably the main causes of the impasse in which environmental sociology now finds itself.

    Geographic, environmental and meteorological conditions, are considered as decisive factors in the basic engineering and design of electric substations. These conditions are considered through the use of environmental and meteorological parameters, such as: pollution type, creepage distance, pollution level, maximum wind rate, maximum temperature, seismic coefficient and maximum pluvial precipitation. In some cases, the pollution level determines the external insulation distance. The pollution level factor is quantified as the equivalent salt accumulation in milligrams per square centimeter of the insulation surface (DESD), occurring during certain time, that produces an electric effect similar to that of the real pollutant. [Espanol] Los aspectos geograficos, ambientales y meteorologicos son factores que se deben considerar en la ingenieria basica de las subestaciones electricas. En el diseno de estas se utilizan parametros asociados con las condiciones ambientales y meteorologicas, como son: tipo de contaminacion, distancia de fuga, nivel de contaminacion, velocidad maxima del viento, temperatura ambiental maxima, temperatura ambiental minima, coeficiente sismico y maxima precipitacion pluvial. La contaminacion se produce por la depositacion de polvo y otras sustencias quimicas sobre los aisladores. Para cuantificar la contaminacion se recurre al concepto de Densidad Equivalente de Sal Depositada (DESD), que consiste en medir la contaminacion en funcion de la cantidad de sal (NaC1) depositada en cierto tiempo, por centimetro cuadrado del aislador, tal que su comportamiento electrico es equivalente al de los contaminantes reales.

    Country economic growth is proportional bond to it electric generation increasing capacity. Brazil, which has a power matrix predominantly renewable, currently is increasing generation, from thermoelectricity, due, mainly, to major facilities in relation to environmental licensing. Since this new Thermal Power Plants operating, tied to the generation with those ones already installed, will result in environmental impacts that must be properly controlled. Such control should follow the Environmental Performance Evaluation guidance, standardized by ABNT NBR ISO 14031/04. Therefore, the following work presents the main Environmental Performance Indicators applied to several thermoelectric generation styles (Oil, Natural Gas, Diesel, Mineral Coal, Biomass, Waste, Solar and Nuclear).

    Full Text Available O pressuposto deste ensaio é o de que, ao longo de sua trajetória, a educação ambiental foi constituindo uma narrativa que lhe é própria. Algumas palavras com sentidos conceituais polissêmicos, como natureza, participação, solidariedade, cooperação, autonomia, interdisciplinaridade e, mais recentemente, sustentabilidade, transdisciplinaridade e transversalidade, fundamentam a Educação Ambiental e fazem parte de seu léxico ou de sua rede semântica. O objetivo é analisar os campos do sentido produzidos por alguns desses termos e a trama de inter-relações entre os sujeitos e suas práticas discursivas, recusando a doutrina da unidade da razão e de um sujeito unitário em direção ao objetivo da perfeita coerência. Como a linguagem forma-se no seio de uma cultura, transita entre o individual/ coletivo, o subjetivo/ cultural, no caso da Educação Ambiental, é carregada de sentidos e de significados de um paradigma emergente, de novos modos de sensibilidades entre utopistas e utopias. É propósito entender se, de fato, a Educação Ambiental, em nome da emancipação, opõe-se ao projeto liberal de uma "razão educadora", de um conhecimento-regulação, de uma educação universal baseada em métodos universais, analisando de modo complexo a função social das narrativas generalistas e/ou denunciatórias. Foi considerado tanto o potencial positivo como os limites analíticos e estratégicos das narrativas que se manifestam de forma auto-referenciais. A preocupação central e conclusiva é: as práticas cotidianas que demandam iniciativas e encaminhamentos podem fazer sentido e criar campos de interface para o exercício de uma Educação Ambiental?The assumption behind this essay is that, throughout its history, environmental education constituted a narrative of its own.

    From the beginning of the 90s the analysis of the relationships between economic growth and environmental pressures has been influenced by the Environmental Kuznets Curve hypothesis or inverted-U shaped relationship between environmental pressure and per capita income. Following this hypothesis, once achieved certain income level, more economic growth is followed by environmental quality improvement. In this paper, we analyse and discuss the theories that support this hypothesis as well as the empirical evidence on this subject. Further on we analyse the relationship between per capita income and the main environmental pollutants for the case does not support the hypothesis. The empirical evidence shows that economic growth, by itself, does not entail a pollution reduction. (Author) 35 refs.

    Full Text Available No decorrer das últimas três décadas, a história ambiental se tornou um subcampo reconhecido com seus próprios clássicos, um grande número de monografias notáveis, um fluxo contínuo de artigos publicados e mais do que mil pesquisadores ativos em vários continentes, incluindo uma comunidade crescente na América Latina. Um olhar para além dos limites disciplinares da história mostra que há também outras tradições que se enquadram perfeitamente na temática. A geografia histórico-cultural da Escola de Berkeley sob a égide de Carl Sauer talvez seja uma dessas perspectivas alternativas conhecidas. Muitos estudos de Sauer, seus alunos e colaboradores podem ser considerados pesquisas em história ambiental; muitas delas se baseiam em matérias sobre a América Latina. Neste artigo, procuramos traçar o desenvolvimento dessa corrente alternativa para a história ambiental que se iniciou com a tese de doutoramento de Carl Sauer em 1915 e se consolidou nos anos 50, tendo sua continuidade no presente através dos trabalhos de diversos geógrafos.Over the past three decades environmental history has become a recognized subfield, with a cannon of classics, many dozens of distinguished monographs, a steady flow of published articles, and more than one thousand active practitioners on several continents, including a growing cohort in Latin America. If one looks beyond history's disciplinary bounds, one finds other traditions that equally fit perfectly into the array of environmental history. Perhaps the broadest and deepest current is represented by Carl Sauer's Berkeley School of cultural-historical geography. Much of the work of Sauer, his students, and his associates, can be considered environmental history. Moreover, much of it is based on Latin American materials. In this paper, we trace the development of an alternative current within environmental history - one that began with Carl Sauer's doctoral dissertation in 1915, became well

    The present investigation provides novel information on the topographical distribution of macrophages and dendritic cells (DCs) in normal meninges and choroid plexus of the rat central nervous system (CNS). Whole-mounts of meninges and choroid plexus of Lewis rats were incubated with various anti-leucocyte monoclonal antibodies and either visualised with gold-conjugated secondary antibody followed by silver enhancement and subsequent examination by environmental scanning electron microscopy or by the use of fluorochromes and confocal microscopy. Large numbers of MHC class II(+) putative DCs were identified on the internal or subarachnoid aspect of dural whole-mounts, on the surface of the cortex (pia/arachnoid) and on the surface of the choroid plexus. Occupation of these sites would allow DCs access to cerebrospinal fluid (CSF) and therefore allow antigens into the subarachnoid space and ventricles. By contrast, macrophages were less evident at sites exposed to CSF and were more frequently located within the connective tissue of the dura/arachnoid and choroid plexus stroma and also in a sub-pial location. The present data suggest that DC may be strategically located within the CNS to sample CSF-borne antigens. Furthermore, the data suggest that CNS tissue samples collected without careful removal of the meninges may inadvertently be contaminated by DCs and meningeal macrophages.

    A key to understanding control over mineral formation in mollusk shells is the microenvironment inside the pre-formed 3-dimensional organic matrix framework where mineral forms. Much of what is known about nacre formation is from observations of the mature tissue. Although these studies have elucidated several important aspects of this process, the structure of the organic matrix and the microenvironment where the crystal nucleates and grows are very difficult to infer from observations of the mature nacre. Here, we use environmental- and cryo-scanning electron microscopy to investigate the organic matrix structure at the onset of mineralization in the nacre of two mollusk species: the bivalves Atrina rigida and Pinctada margaritifera. These two techniques allow the visualization of hydrated biological materials coupled with the preservation of the organic matrix close to physiological conditions. We identified a hydrated gel-like protein phase filling the space between two interlamellar sheets prior to mineral formation. The results are consistent with this phase being the silk-like proteins, and show that mineral formation does not occur in an aqueous solution, but in a hydrated gel-like medium. As the tablets grow, the silk-fibroin is pushed aside and becomes sandwiched between the mineral and the chitin layer.

    Initial microbial adhesion to surfaces is a complicated process that is affected by a number of factors. An important property of a solution that may influence adhesion is pH. The surface properties of the cedar wood were characterized by the sessile drop technique. Moreover, the interfacial free energy of surface adhesion to the cedar wood was determined under pH values (2, 3, 5, 7, 9 and 11). The results showed that cedar wood examined at different pH levels could be considered hydrophobic ranged from Giwi = -13.1 mJ/m(2) to Giwi = -75 mJ/m(2). We noted that the electron-donor character of cedar wood was important at both basic and limit acidic conditions (pH 11 and pH 3) and it decreased at intermediate pH (pH 5). The cedar wood substratum presents a weak electron acceptor under various pH's. In addition, the adhesion of conidia from Penicilllium expansum to the cedar wood surfaces at different pH values (2, 3, 5, 7, 9 and 11) was investigated using Environmental Scanning Electron Microscopy and image analysis was assessed with the Mathlab(®) program. The data analysis showed that the conidia from P. expansum were strongly influenced by the pH. The maximum adhesion occurs in the pH 11 and pH 3 and decreased to 24% at pH 5.

    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.

    Full Text Available Ante el creciente deterioro ambiental y sus posibles consecuencias en la salud de la población resulta una prioridad indiscutible el diseño e instrumentación de políticas que controlen las actividades económicas bajo el criterio de protección a la salud humana y al ambiente mismo. Es preciso que dichas políticas consideren la factibilidad económica de las alternativas de protección existentes. Sin embargo, por la cantidad de intereses dentro del área ambiental, otros factores como el social y el político deben también ser considerados. La evaluación económica ha sido vista como un promisorio fundamento para la toma de decisiones en esta materia. Los autores analizan la capacidad de esta herramienta para organizar en forma sistemática y comparable los costos y los beneficios de alternativas para la solución de problemas ambientales. Se resumen las principales características de los estudios de costo-beneficio y costo-efectividad, las formas de evaluación económica del ambiente, y las particularidades de esta área para la aplicación de dichas técnicas de análisis. Se señalan los límites encontrados en estas herramientas para cuantificar los costos no monetarios de los riesgos ambientales y de los consecuentes daños a la salud, tales como el dolor, el sufrimiento ó la incapacidad de personas económicamente inactivas, constituyendo estos aspectos el reto metodológico de la evaluación económica en el área. Se reflexiona sobre la importancia de ampliar los insumos informativos para la toma de decisiones en materia de salud ambiental en aspectos como la distribución de los costos y los beneficios entre los distintos grupos sociales. Por último se señala tanto la creciente politización del tema ambiental, como la posibilidad técnica de manipulación de estas herramientas de análisis. Partiendo de estos elementos se señala la necesidad, por parte de los evaluadores, de ser conscientes sobre las implicaciones pol

    Full Text Available The need for an instrument to support the environmental licensing of the mining activity held in the Sorocaba river watershed State of São Paulo, led the Geological Institute to develop, in partnership with the Environmental Company of State of São Paulo – CETESB, a computational tool able to perform the input, edition, queries and visualization of the mining companies data. The aim of this tool is to provide a regional analysis to the licensing agency favoring the identification and evaluation of critical areas and related potential conflicts, according to criteria of densification, environmental degradation, commitment of water resources, proximity to urban areas and conservation units. This paper expresses the activity in the region and describes the structures and main features of the Geographic Information System. The development of GIS, designed in a client–server environment, mainly comprised its modeling and database organization, developed from information assessment in the CETESB’s environmental agencies of Itu, Botucatu and Sorocaba and involved the preparation and edition of several thematic maps. The developed and now being implemented system allows the user to access and interact with a georeferenced database of mining enterprises and licensing activities, mining supervision and control in the area of the watershed that may be extended to other environmental agencies of the State of São Paulo. = A necessidade de um instrumento de apoio ao processo de licenciamento ambiental da atividade minerária praticada na Bacia Hidrográfica do Rio Sorocaba, São Paulo, levou o Instituto Geológico - IG a desenvolver, em parceria com a Companhia Ambiental do Estado – (CETESB uma ferramenta computacional apta a executar entrada, edição, consultas e visualização de dados relativos a esta atividade econômica.

    The aim of this study was to determine the effects of daily ranges and maximum ambient temperatures, and other risk factors on reproductive failure of Landrace (L) and Yorkshire (Y) sows under an open-house system in Thailand. Daily ambient temperatures were added to information on 35,579 litters from 5929 L sows and 1057 Y sows from three commercial herds. The average daily temperature ranges (ADT) and the average daily maximum temperatures (PEAK) in three gestation periods from the 35th day of gestation to parturition were classified. The considered reproductive failure traits were the occurrences of mummified fetuses (MM), stillborn piglets (STB), and piglet death losses (PDL) and an indicator trait for number of piglets born alive below the population mean (LBA). A multiple logistic regression model included farrowing herd-year-season (HYS), breed group of sow (BG), parity group (PAR), number of total piglets born (NTB), ADT1, ADT2, ADT3, PEAK1, PEAK2, and PEAK3 as fixed effects, while random effects were animal, repeated observations, and residual. Yorkshire sows had a higher occurrence of LBA than L sows (P = 0.01). The second to fifth parities sows had lower reproductive failures than other parities. The NTB regression coefficients of log-odds were positive (P < 0.01) for all traits. Narrower ranges of ADT3 increased the occurrence of MM, STB, and PDL (P < 0.01), while higher PEAK3 increased the occurrence of MM, STB, PDL, and LBA (P < 0.001). To reduce the risk of reproductive failures, particularly late in gestation, producers would need to closely monitor their temperature management strategies.

Apresentam-se os limitados avanços da pesquisa nessa área, marcada por um processo lento, com gradual posicionamento institucional acerca da Educação Ambiental regional. O surgimento da educação para o desenvolvimento sustentável, à exceção da Colômbia, não chegou a alterar esse processo, nem tampouco a criar novas e mais favoráveis condições de impulso à pesquisa numa perspectiva sociopolítica. Apesar disso, o artigo reporta avanços positivos em direção à pesquisa na Educação Ambiental, embora não se possam esperar resultados espetaculares a curto e médio prazos, a menos que se apresente uma mudança radical da atual situação, o que não se vislumbra neste momento.This article aims at analyzing the current state of research in Environmental Education in Latin America. With emphasis on Mexico and Brazil, it also provides general descriptions of Colombia, Cuba, Ecuador and Venezuela. We present the limited research advances in this area, characterized by a slow process, with gradual institutional positioning on regional Environmental Education. The emergence of education for sustainable development, except the Colombian case, did not change this process, nor created new and more favorable conditions to boost researches into a socio-political perspective. Nevertheless, this article reports positive progress towards researches in Environmental Education. Yet, spectacular results for a short to medium term are not to be expected, unless a radical change can be brought about in the current situation, which is not currently expected.

    Full Text Available A problemática ambiental constitui, atualmente, um importante espaço catalisador e produtor de valores regulatórios da vida humana e não-humana na biosfera terrestre. Porém, o que faz com que esta temática adquira tamanha envergadura em relação à sua identificação como problema social importante? A hipótese lançada aqui é a de que por trás desta difusa sensibilidade ambiental encontra-se em processo a configuração de um campo ambiental relativamente estruturado, no qual se busca, cada vez mais, a legitimidade para tratar das discussões sobre tudo aquilo que diz respeito ao meio ambiente. Neste sentido, tal espaço de lutas simbólicas tende a concentrar confrontos em torno do reconhecimento de certas ações e modos de pensamento, sendo que o que está colocado em jogo, neste caso, são as próprias percepções acerca do que seja o meio ambiente e, em contrapartida, as relações ontológicas construídas entre seres humanos e natureza. Com isto, a paulatina estruturação de um campo ambiental - este último funcionando como um amplo, dinâmico, instável e heterogêneo espaço de debate e de ação - tende a fazer com que determinados conceitos e práticas possam naturalizar-se e, concomitantemente, serem reconhecidas como "ambientalmente corretas". Em suma, a constituição deste domínio prático/discursivo irá concentrar os agentes e suas disputas sobre que saberes, comportamentos e procedimentos deveriam ser instituídos como sendo os mais "adequados" do ponto de vista ambiental. Entretanto, nesta perspectiva, o que seria visto (e adotado como ambientalmente "correto" ou "adequado" está, desde já, em disputa.At present, the environmental question constitutes an important space of catalysis and production of regulatory values of human and non-human life in the earth's biosphere.

    The implementation of oil and gas pipeline systems are commonly made in a own or shared with power transmission, rail and crossroads right-of-way. Pipelines are a 'linear' structure, such as power transmission lines, which are established on landscapes with several conformations (accent slopes, swamp and rocky soils), including sites with high environmental sensibility. The services involved on pipeline implementation are very dynamic, involving several number of employees, vehicles, heavy equipment of excavation and welding that results in a high potential to cause environmental and social impacts. This article, based on the Brazilian and foreign experience on pipeline construction, proposes a methodology to prevent and minimize social and environmental impacts during the construction stage of a pipeline system.

O estudo de caso focaliza uma filial de empresa multinacional localizada no Estado do Rio de Janeiro, que oferece soluções de energia temporária e sistemas de controle de temperatura. Foram selecionados oito funcionários de diferentes setores da empresa para a ponderação das alternativas, de acordo com os diferentes critérios qualitativos. Foi demonstrado que existem conflitos de opinião em relação à priorização das alternativas. Isso ocorreu devido à interdependência das alternativas e porque os diferentes atores visualizam o problema com perspectivas diferentes e têm interesses diversos. Os resultados mostraram que a principal alternativa, segundo a maioria dos atores, é a implementação de um programa de educação ambiental para evitar desperdícios e informar/conscientizar os empregados sobre as questões ambientais.

Partindo de uma conceptualização multidimensional prévia, feita com estudantes universitários, o objetivo principal é testar uma medida de quatro dimensões de atitudes ambientais numa amostra da população em geral (N = 245. Além disso, é feita a análise da relação entre as dimensões desta atitude e quatro categorias de comportamentos ambientais. Os resultados confirmam a validade e fiabilidade do modelo conceptual de medição, e suportam os diferentes constructos de atitudes envolvidas, mostrando um duplo esquema de preocupação ambiental, onde as atitudes antropocêntricas e ecocêntricas estão em conflito. Em relação aos comportamentos ecológicos, as condutas mais frequentes foram as que exigem menos implicação e compromisso pessoal na sua execução. O impacto da apatia ambiental foi negativo em todos os comportamentos analisados. A multidimensionalidade da preocupação ambiental permite estabelecer um perfil mais preciso sobre as atitudes e comportamentos ambientais das pessoas.

    Full Text Available El abordaje jurídico de la problemática ambiental constituye uno de los mayores desafíos que ha afrontado el derecho, ya que requiere la comprensión del ambiente como un todo que no reconoce fronteras políticas. Esa comprensión, que implica el reconocimiento de nuevos paradigmas, sólo puede lograrse incorporando al sistema de derecho como bien supremo de tutela, la calidad de vida de los seres humanos. El concepto de ambiente, se encuentra indisolublemente relacionado con el de desarrollo sustentable y el de calidad de vida, imbrincándose todos ellos en torno al ser humano, protagonista central y responsable individual y socialmente de su destino y del futuro del planeta. Resulta necesaria la incorporación de la perspectiva de género en la gestión del desarrollo sustentable, ya que el mejoramiento de la calidad de vida sólo puede alcanzarse si el concepto de equidad que presupone, incluye la equidad de género. Hemos considerado los principales instrumentos jurídicos de protección ambiental de alcance internacional a efectos de analizar la incorporación de la perspectiva de género en los mismos y concluir respecto del estado de la cuestión.To tackle the juridical aspect of the environmental issue is one of the greatest challenges registered by law, since it implies the understanding of the environment as a whole without any political frontier. This acknowledgement, that involves the recognition of new paradigms, can only be accomplished by incorporating to the law system as a supreme guardianship good, the quality of life for every human being. The concept of enviroment is closely related to sustainable development and quality of life, overlapping all of them around the human being, the central protagonist and responsible individually and socially of his own destiny and the planet´s future. It is necessary to incorporate the gender perspective in the sustainable development management, since quality of life improvement can only

    Full Text Available This study aimed to evaluate the co-occurrence of caffeine and the extent of its influence as compared to other traditional water quality parameters (microbiological and physico-chemical in order to characterize it as an efficient indicator of anthropic pollution of urban aquatic environments. Caffeine is an ingredient in a variety of beverages (coffee, tea, and caffeinated soft drinks and numerous food products (chocolate, pastries, and dairy desserts. Although the human body metabolizes this stimulant efficiently, between 0.5 and 10.0% is excreted, mostly in the urine. Analysis of water samples from the Leopoldina Basin and Guanabara Bay revealed a significant difference between areas not commonly affected by nutrient enrichment or sewage inputs and areas chronically influenced by sewage discharges and elevated eutrophication. Monitoring caffeine will be fundamental in stressed urban aquatic environments where frequent accidental ruptures of sewer lines and discharges of untreated effluents impede effective water quality evaluation with traditional indicators.Este estudo visou avaliar a co-ocorrência de cafeína e a extensão de sua influência frente a outros parâmetros tradicionais de qualidade de água (microbiológicos e físico-químicos, de modo a caracterizá-la como um eficiente indicador de poluição de origem antrópica em ambientes aquáticos urbanos.

    The document describes the outcome of the CSN/CIEMAT-02 interlaboratory test comparison among environmental radioactivity laboratories. The exercise was organised according to the ISO-43 and the ISO/IUPAC/AOAC Harmonized Protocol for the proficiency testing of analytical laboratories. The test sample was a reference materials provided by the IAEA-MEL (IAE Marine Environmental Laboratory, Monaco), a sea fish containing environmental levels of U-238, U-234, K-40, Pb-210, Ra-226, Sr-90, Cs-137, Co-60, Pu-(239+240), Am-241 and Tc-99. The results of the exercise were computed for 32 participating laboratories, and their analytical performance was assessed using the z-score approach. A raised percentage of satisfactory laboratory performance has been obtained for all the analysis, being the best performance in gamma measurements. The laboratories have made an effort to calculate the combined uncertainty of the radiochemical determinations. Most of the laboratories have demonstrated its competence in performing the study analysis and also the adequate measuring capability of their detection equipment even in conditions close to detection limits. The study has shown the capacity of participant laboratories to perform radioactive determinations in environmental sea fish samples with satisfactory quality levels. (Author) 6 refs.

    The Environmental Pre-Communication is a tool developed to identify the profiles of communities surrounding the marked area (lifestyle, resources, fragilities, beliefs, culture and wishes), how they make their living, and production (community dependence relationship with ecosystems, such as rivers and subsistence areas), social organization, needs and expectations. Besides developing a social economic diagnostic, pre-communication prepares a community perception study. Regarding gas pipelines, the area of study comprehends 200 m towards each side of gas pipeline right-of-way in rural areas and 400 m towards each side in urban areas. Pre-Communication diagnostic, which is included in the process of environmental licensing, is aimed at subsidizing EIS (Environmental Impact Statement), providing data which help to elaborate mitigating and compensatory plans and programs. Moreover, diagnostic information make it possible to run public forums before Public Hearings take place, aiming at clarifying specific community issues related to construction and reduction of resistances, avoiding problems and conflicts. Also, during the entrepreneurship implementation phase, there is the advantage to know the bordering community and its daily activities, increasing the effectiveness of Environmental Programs.

    The multi discipline effects in engineering projects, mainly in those of infrastructure, have extended the borders of research to not only evaluate them of the conventional point of view, economic and technical, but also environmental and social. On the other hand, the investor who traditionally searched alternatives only considering the economic and financial performance currently is taken to analyze also the social and environmental aspects. The model described in this paper is a solution proposal to evaluate the merit of an enterprise of distributed generation of thermal origin, considering the economic, social and environmental aspects, using merit indexes that quantify, directly, economic aspects as capital return tax and operating income eliminates, as well as social factors like the impact in the education, health, income and employment rates and still, it verifies the attendance of the environmental restrictions. The solution presented brings a simple and clear form to attribute a merit degree of aggregate to the alternatives to embed distributed generation, considering the intensity of the subjective social responsibility of the investor. The presented model is an important contribution to stimulate a form to evaluate and to prioritize the multi discipline implementation to a distributed generation enterprise, also being able, to be used as financial index or other incentives of the sort.

    Full Text Available O texto resume as principais questões e conclusões alcançadas na minha tese de doutoramento junto ao Curso de Pós-Graduação em Desenvolvimento, Agricultura e Sociedade - CPDA da UFRRJ. A discussão em torno da interdisciplinaridade ambiental vem crescendo nos últimos anos, tendo sido os anos 1970 e 1980 férteis o suficiente para possibilitar, nos 1990, a construção de uma Educação Ambiental ao nível da especialização profissional. A inserção da temática ambiental no meio acadêmico se fez gradativamente e, embora com muitos obstáculos, tem demonstrado um viés inovador e desafiante de administradores, docentes e discentes tendo em vista a estrutura fragmentada das universidades tradicionais. O exame do estado da arte das Ciências Ambientais possibilitou discernir, para além da compartimentalização e da departamentalização, as principais queixas, dúvidas, caminhos, soluções e espaços que conduziram à elaboração de um campo integrador do fazer científico, reunindo ensino, pesquisa e extensão. O processo de institucionalização exemplificado nos quatro programas brasileiros de pós-graduação estudados permite revelar o quanto se tem progredido no diálogo entre autores/atores das mais diversas origens acadêmicas, promovendo uma interfecundação de grande interesse profissional para os participantes e para o desenvolvimento de uma sociedade sustentável, confirmando até certo ponto a construção de um paradigma para além do reducionismo epistemológico.This article addresses questions that emerged in my research about the matter of cross-disciplinary sciences on environmental issues.

    The environmental sanitation sector accounts for 3% of all electric energy consumed. Along with the Electric System it is an important user of the hydro graphic basins. In 2003 ELETROBRAS created PROCEL SANEAR in order to promote the efficient use of energy and water in the environmental sanitation systems and by its consumers. This paper presents the Action Plan of PROCEL SANEAR 2006-2007 displaying its main ongoing actions: the implementation of projects of water and energy conservation selected by means of public hearings, the training of professionals with seminars for the high management and courses for the managers of sanitation services providers and the installation of equipment to implement laboratories of energy and water efficiency in sanitation. PROCEL SANEAR, a nationwide program, seeks to reach through its activities endurance and sustain ability aiming at minimizing isolated and discontinued actions. Thus, PROCEL SANEAR contributes to shift paradigms by causing service providers to prioritize the conservation of water and electric energy. (author)

    Transgene introgression into crop weedy/wild relatives can provide natural selective advantages, probably causing undesirable environmental impact. The advantages are likely associated with factors such as transgenes, selective pressure, and genetic background of transgene recipients. To explore the role of the environment and background of transgene recipients in affecting the advantages, we estimated the fitness of crop-weed hybrid lineages derived from crosses between marker-free insect-resistant transgenic (Bt/CpTI) rice with five weedy rice populations under varied insect pressure. Multiway anova indicated the significant effect of both transgenes and weedy rice genotypes on the performance of crop-weed hybrid lineages in the high-insect environment. Increased fecundity was detected in most transgene-present F1 and F2 hybrid lineages under high-insect pressure, but varied among crop-weed hybrid lineages with different weedy rice parents. Increased fecundity of transgenic crop-weed hybrid lineages was associated with the environmental insect pressure and genotypes of their weedy rice parents. The findings suggest that the fitness effects of an insect-resistant transgene introgressed into weedy populations are not uniform across different environments and genotypes of the recipient plants that have acquired the transgene. Therefore, these factors should be considered when assessing the environmental impact of transgene flow to weedy or wild rice relatives.

    Full Text Available This article’s scope is to examine the application of fundamental rights related to the environment in the Brazilian legal system, in order to demonstrate the impact of international environmental law, based on the statement of a normative development at international and national levels with more progressive character in environmental harvest, focusing on international environmental principles, notably on the principle of popular participation. It attempts to establish the international instruments that deal with the matter, with particular attention to the Aarhus Convention, in order to analyze how was the impact on the national system considering the participation as a structural foundation of the democratic exercise and eco-citizenship. The comparative method was carried out in the study of convergences and divergences between the Aarhus Convention and the Law n. 10.650/2003, as well as, in the application of historical and inductive methods for establishing conceptual premises of access to information. Thus, the goal was to identify common elements between the two types of regulation, seeking to define the content and the scope of the guarantor measures of access to information and participation. Based on that, the environment can be recipient of a greater protection at the same time of decision-making in any field or ambit of action, either in global or national level.

    Full Text Available A multiplicação dos riscos, em especial os ambientais e tecnológicos de graves conseqüências, é elemento chave para se entender as características, os limites e as transformações da nossa modernidade. É cada vez mais notória a complexidade desse processo de transformação de uma sociedade cada vez mais não só ameaçada, mas diretamente afetada por riscos e agravos socioambientais. Os riscos contemporâneos explicitam os limites e as conseqüências das práticas sociais, trazendo consigo um novo elemento, a "reflexividade". A sociedade, produtora de riscos, torna-se crescentemente reflexiva, o que significa dizer que ela se torna um tema e um problema para si própria. O conceito de risco passa a ocupar um papel estratégico para o entendimento das características, dos limites e das transformações do projeto histórico da modernidade e para reorientar estilos de vida coletivos e individuais. Num contexto marcado pela degradação permanente do meio ambiente e do seu ecossistema, isso envolve um conjunto de atores do universo educativo em todos os níveis, potencializando o engajamento dos diversos sistemas de conhecimento e a sua capacitação numa perspectiva interdisciplinar. Os educadores têm um papel estratégico e decisivo na inserção da educação ambiental no cotidiano escolar, qualificando os alunos para um posicionamento crítico face à crise socioambiental, tendo como horizonte a transformação de hábitos e práticas sociais e a formação de uma cidadania ambiental que os mobilize para a questão da sustentabilidade no seu significado mais abrangente.The proliferation of risks, particularly of those of severe environmental and technological consequences, is a key element to understand the features, limitations and transformations of our modernity.

    The relationships between ambient PM2.5 and PM10 and arrhythmia and the effect modification by cigarette smoking were investigated. Data from EPA air quality monitors and an established national-scale, log-normal kriging method were used to spatially estimate daily mean concentrations of PM at addresses of 57,422 individuals from 59 examination sites in 24 US states in 1999-2004. The acute and subacute exposures were estimated as mean, geocoded address-specific PM concentrations on the day of, 0-2 days before, and averaged over 30 days before the ECG (Lag0; Lag1; Lag2; Lag1-30). At the time of standard 12-lead resting ECG, the mean age (SD) of participants was 67.5 (6.9) years (84% non-Hispanic White; 6% current smoker; 15% with coronary heart disease; 5% with ectopy). After the identification of significant effect modifiers, two-stage random-effects models were used to calculate center-pooled odds ratios and 95% confidence intervals (OR, 95% CI) of arrhythmia per 10 μg/m3 increase in PM concentrations. Among current smokers, Lag0 and Lag1 PM concentrations were significantly associated ventricular ectopy (VE) - the OR (95% CI) for VE among current smokers was 2 (1.32-3.3) and 1.32 (1.07-1.65) at Lag1 PM2.5 and PM10, respectively. The interactions between current smoking and acute exposures (Lag0; Lag1; Lag2) were significant in relationship to VE. Acute exposures were not significantly associated with supraventricular ectopy (SVE), or with VE among non-smokers. Subacute (Lag1-30) exposures were not significantly associated with arrhythmia. Acute PM2.5 and PM10 exposure is directly associated with the odds of VE among smokers, suggesting that they are more vulnerable to the arrhythmogenic effects of PM. PMID:18979352

    Atmosphere and Ambient Space This paper explores the relation between atmosphere and ambient space. Atmosphere and ambient space share many salient properties. They are both ontologically indeterminate, constantly varying and formally diffuse and they are both experienced as a subtle, non......-signifying property of a given space. But from a certain point of view, the two concepts also designate quite dissimilar experiences of space. To be ’ambient’ means to surround. Accordingly, ambient space is that space, which surrounds something or somebody. (Gibson 1987: 65) Since space is essentially...... of a surrounding character, all space can thus be described as having a fundamentally ambient character. So what precisely is an ambient space, then? As I will argue in my presentation, ambient space is a sensory effect of spatiality when a space is experienced as being particularly surrounding: a ‘space effect...

    Recent work has highlighted micro-scale roughness on the surfaces of ice crystals grown and imaged in-situ within the chambers of environmental scanning electron microscopes (ESEM). These observations appear to align with theoretical and satellite observations that suggest a prevalence of rough ice in cirrus clouds. However, the atmospheric application of the lab observations are indeterminate because the observations have been based only on crystals grown on substrates and in pure-water vapor environments. In this work, we present details and results from the development of a transfer technique which allows natural and lab-grown ice and snow crystals to be captured, preserved, and transferred into the ESEM for 3D imaging. Ice crystals were gathered from 1) natural snow, 2) a balloon-borne cirrus particle capture device, and 3) lab-grown ice crystals from a diffusion chamber. Ice crystals were captured in a pre-conditioned small-volume (~1 cm3) cryo-containment cell. The cell was then sealed closed and transferred to a specially-designed cryogenic dewer (filled with liquid nitrogen or crushed dry ice) for transport to a new Hitachi Field Emission, Variable Pressure SEM (SU-5000). The cryo-cell was then removed from the dewer and quickly placed onto the pre-conditioned cryo transfer stage attached to the ESEM (Quorum 3010T). Quantitative 3D topographical digital elevation models of ice surfaces are reported from SEM for the first time, including a variety of objective measures of statistical surface roughness. The surfaces of the transported crystals clearly exhibit signatures of mesoscopic roughening that are similar to examples of roughness seen in ESEM-grown crystals. For most transported crystals, the habits and crystal edges are more intricate that those observed for ice grown directly on substrates within the ESEM chamber. Portions of some crystals do appear smooth even at magnification greater than 1000x, a rare observation in our ESEM-grown crystals. The

    A long-standing goal of electron microscopy has been the high-resolution characterization of specimens in their native environment. However, electron optics require high vacuum to maintain an unscattered and focused probe, a challenge for specimens requiring atmospheric or liquid environments. Here, we use an electron-transparent window at the base of a scanning electron microscope's objective lens to separate column vacuum from the specimen, enabling imaging under ambient conditions, without a specimen vacuum chamber. We demonstrate in-air imaging of specimens at nanoscale resolution using backscattered scanning electron microscopy (airSEM) and scanning transmission electron microscopy. We explore resolution and contrast using Monte Carlo simulations and analytical models. We find that nanometer-scale resolution can be obtained at gas path lengths up to 400 μm, although contrast drops with increasing gas path length. As the electron-transparent window scatters considerably more than gas at our operating conditions, we observe that the densities and thicknesses of the electron-transparent window are the dominant limiting factors for image contrast at lower operating voltages. By enabling a variety of detector configurations, the airSEM is applicable to a wide range of environmental experiments including the imaging of hydrated biological specimens and in situ chemical and electrochemical processes.

Para tanto, a ação do Estado é primordial como indutor e regulador do processo, bem como, sendo um dos principais financiadores deste projeto, conciliando uma nova política industrial ambientalmente sustentável com mudanças na política monetária e cambial, para que a ação possa ser realmente efetiva.This work presents a proposal for political and economic direction to be taken in Brazilian industry. This proposal suggests going back to a time of of environmental sustainability as a strategic position in international competitiveness, which would serve as an alternative in combatting the current process of deindustrialization in the country. Brazil should leverage its leadership in certain areas such as sustainable energy production and availability of natural resources in order to redirect the industrial process through the use of an economic policy that integrates environmental issues and the need to reindustrialize the economy. For this to occur, government action is paramount and must initiate and regulate the process. The state must also provide the main financial support of this project, which would combine a new environmentally sustainable industrial policy with changes in monetary and exchange policy, so that actions taken can be truly effective.

The objective of this study was to evaluate the structural quality of soil cultivated with coffee and used as pasture in the Capituva's River microbasin, which is located in the Environmental Protection Area in Coqueiral, south of the state of Minas Gerais. Uniaxial compression test (preconsolidation test and soil resistance to penetration were used. Undisturbed samples were taken from the surface layer (0-5 cm of the soils in the area: a typic dystrophic Red Latosol (LVd - Oxisol, a typic eutrophic Red Argisol (PVe - Ultisol, and a typic dystrophic Haplic Cambisol (CXbd - Inceptisol. A significant linear positive correlation was observed between the results of the preconsolidation test and soil resistance to penetration. Load bearing capacity of soil could be estimated accordingly by means of penetration resistance for LVd, PVe, and CXbd. Cambisol - CXbd showed lower loading support capacity and resistance to penetration than LVd and PVe, due to the better crop management in this soil that resulted in higher physical quality which accounts for higher production and environmental sustainability.O estudo do solo em áreas de proteção ambiental (APAs é de grande importância, pelo fato deste ser componente essencial dos ecossistemas, interferindo diretamente na sustentabilidade do ambiente.

    The environmental dose equivalent H * (10), is the magnitude recommended by ICRU 39 for environmental monitoring in fields of radiation of photons. Most of the equipment used for area monitoring, only quantifies the magnitudes exposure or dose not being designed to this new magnitude. In Brazil, particularly, is not yet regulated the use of H * (10). However, with the revision of the standard 3.01 it will necessary the use of monitors that allow the achievement of measures according to H * (10). The transition for using new magnitudes will be a slow process and the contribution that the laboratories of metrology of ionizing radiation in the country can give is, at first, promote and create the habit of using the unit Sievert (Sv) in the calibration of the instruments, and that is the unit recommended for H * (10). In a second step, the tests for determining the response of the instruments for H * (10) should be made and this is the harder step, taking into account the large number of area monitors around the country. These tests will provide information about the limitations of the instrument to the new magnitude, that is, the range where the instrument will have the best performance in quantification of new magnitude. This paper evaluates the performance for H * (10), with the variation of energy and angle of incidence of radiation, of three of the most used monitors in the country.

    Gasoline production in petroleum refineries usually implies carrying high phenol contents in water after treatment systems. Phenols are powerful bactericides and, therefore, harmful to microorganisms present in wastewater treatment plants and in rivers. Due to this reason, usually controlled phenolic water drainage is performed, enabling gasoline quality improvement, without jeopardizing the biological treatment. Increase of phenolic contents in the effluent, due to operational disarray during the drainage of gasoline tanks may cause inhibition or even mortality of the existing microorganisms in the wastewater treatment plants. Aiming at changing the traditional treatment logic of environmental demands at the 'end of pipe', sending the phenolic water to the sour water treatment systems was proposed and implemented, which in turn, is reutilized by the latter in the crude desalination of the Distillation Units, where the phenols are reincorporated to the crude oil, preventing negative consequences to the wastewater treatment plant. The implemented process has demonstrated that premises were correct, enabling to implement process flows quite higher than drainage flows, what has meant productivity gains and environmental improvement.

The review was organized according to number of presentations per congress and authors' countries of origin, type of work; thematic areas, types of processes, environments and subjects addressed; methodologies and methods employed; disciplines involved and reference to the ethical political dimension.

    Analysis shows a sustained growth of the discipline, although different between countries and heterogeneous in the issues addressed, ways of approaching these and scope of the results. Results show a prevalence of empirical versus theoretical, methodological and applied work; research privileges individual against collective processes; emphasizes reactive versus active role of participants, and a wide variety of topics, environments, subjects and methods is addressed

    Conclusions refer to the contributions and weaknesses of different nature derived from the review, and challenges faced by the discipline for increasing its theoretical and social relevance. A working agenda is suggested for discussing these challenges, which in addition includes the debate over unifying of diversifying Environmental Psychology, as well as its local or universal nature.El presente artículo analiza aportes latinoamericanos a la psicología ambiental, tomando como eje los trabajos presentados en los últimos seis Congresos Interamericanos de Psicología, que abarcan once años (2001-2011. La revisión se organizó con base en el número de trabajos por congreso y países de procedencia de los autores, tipo de trabajo; áreas temáticas, procesos, ambientes y sujetos abordados, metodología y métodos empleados; disciplinas implicadas. El análisis da cuenta del crecimiento sostenido de la disciplina, aunque desigual entre países y heterogéneo en los asuntos

    Full Text Available A noção de natureza tem tido papel importante na filosofia e também na Educação Ambiental. Filósofos contemporâneos como Gianni Vattimo e Newton Aquiles von Zuben afirmam que uma noção única de natureza contribuiu para a difusão da metafísica dogmática, que por sua vez, solidificou totalitarismos políticos e religiosos. A Educação Ambiental latino-americana tem constituído um campo teórico e espaço público privilegiado para a difusão de noções de natureza, não dogmáticas, nem totalitárias, em estreitas relações com a diversidade cultural e social. Num primeiro momento da Educação Ambiental a noção de natureza estava relacionada aos recursos naturais. Desde que temas específicos relacionados com os discursos contemporâneos sobre a natureza, como a biodiversidade e os transgênicos ganharam o espaço público, argumentamos que a Educação Ambiental se viu diante de novos desafios teóricos, políticos, ecológicos, sociais, culturais e pedagógicos. Neste artigo procuramos identificar e analisar alguns desses desafios tendo como apoio teórico o pensamento do filósofo italiano Gianni Vattimo e do filósofo brasileiro Newton Aquiles von Zuben, nos aspectos relacionados à bioética e ao papel político da educação, na formação de cidadãos e cidadãs. Concluímos que a abordagem dos discursos contemporâneos sobre a natureza possibilita que o diálogo entre a Educação Ambiental e a bioética tende a se ampliar e a se concretizar em práticas sociais e pedagógicas cotidianas, apresentando-se, assim, como alternativa concreta para que cidadãos e cidadãs possam enfrentar os desafios trazidos com a biodiversidade e com os transgênicos, com argumentos científicos, éticos e políticos.The notion of nature has played an important role in philosophy and also in Environmental Education.

    Full Text Available The technological-industrial development occurred in the world unleashed by the Industrial Revolution, causing environmental degradation in worrying proportions. At first, under the influence of the anthropocentric paradigm, the problem of environmental degradation was not given due attention. However, with the development of research in this area, the biocentric paradigm has been developed, which considered the environment as an organic whole in which humans are inseparable components. Since then, the Constitutions of several countries has begun to protect the environment more effectively, including access to environmental justice. This article proposes the inclusion of NGO’s as active legitimates to Popular Environmental Action.O desenvolvimento tecnológico ocorrido no mundo, desencadeado pela Revolução Industrial, ocasionou a degradação ambiental em proporções preocupantes. A princípio, sob influência do paradigma antropocêntrico, não era dispensada a devida atenção ao problema da degradação ambiental. Entretanto, com a evolução de pesquisas neste âmbito, foi se desenvolvendo o paradigma biocêntrico, que considerava o ambiente como um todo orgânico, no qual os seres humanos são componentes indissociáveis. A partir de então, Constituições de diversos Estados passaram a tutelar o meio ambiente de forma mais eficaz, sendo incluído o acesso à justiça ambiental. Este artigo objetiva, deste modo, propor a inclusão das ONG’s como legitimadas ativas para propor Ação Popular Ambiental.

    The European Directive CEE 2092/01 establishes the bases for the ecological agrarian production. Several vineyard plantations in Penedes (Barcelona, Spain) have modified the general agrarian practices to comply with this legislation and be certified as ecological grape. The study compares through LCA methodology the standard and the ecological cultivation of the vineyard. Main difference between both kind of cultivation is use of pesticides and fertilizers, much more restricted in the ecological cultivation. Another difference is grape production, bigger in the standard cultivation. The results show a more reduced environmental impact for the ecological cultivation in every impact category studied. The impact categories with a bigger difference are Human Toxicity an Ecotoxicity. (Author)

    In order to evaluate the physical value of mineral and water reserves, the concept of Exergy Replacement Cost has been defined as the energy required by the best available technologies to return a resource to the same conditions as it was delivered by the ecosystem. In the case of fossil fuel reserves, a new concept called exergy abatement cost has been proposed as a physical way of measuring the exergy cost of the best available technology for avoiding the environmental externalities associated with the use of fossil fuels. According to the results obtained, the physical value of mineral reserves is 15.4% of oil reserves. In the case of water reserves, 0,4 to 6,4 times the fossil energy consumed would be needed each year to supply only a part of the functions of the hydrological cycle. The global exegetic abatement costs would be 11,3% of the proven world exegetic reserves in fossil fuels. (Author)

    Selective demolition practices have not yet become popular in our country. Unlike conventional demolition practices, selective demolition helps to increase the amount of components to be reused or materials to be recycled. Thus, the percentage of demolition waste deposited in landfills can be reduced, and the production of recycled materials with optimum quality is fostered. Taking the case study of selective demolition carried out in the municipally of Lasarte-Oria (Basque Country-Spain) as its basis, this paper presents an economic and environmental analysis of the same. Likewise, the economic costs deriving from selective demolition are compared with analogous costs from conventional demolition with an aim to establishing the ideal frame supporting economically feasible selective demolition.

    Full Text Available Ao mesmo tempo em que a empresa proporciona valor aos seus acionistas, também pode fornecer educação, cultura, lazer e justiça social aos funcionários; e ainda, não prejudicar a vida e a diversidade dos ecossistemas. Ou seja, a empresa pode atuar em três dimensões da Sustentabilidade Empresarial: Econômica, Social e Ambiental. Este artigo foca nessa última. Alguns setores como o do etanol, por serem muitas vezes divulgado como um setor ligado a energia renovável, deveriam ser exemplo de evidenciação ambiental. Este artigo objetiva responder ao seguinte questionamento: como as empresas produtoras de etanol, com ações listadas na BOVESPA e NYSE, informam sobre os gastos e benefícios incorridos nas atividades ambientais: por meio de palavras apenas ou valores monetários são também divulgados? Há um padrão na evidenciação? Por meio de uma Pesquisa Estudo de Caso, conclui-se que as empresas produtoras de etanol com ações listadas na BOVESPA e NYSE evidenciam informações ambientais por meio de textos escritos e não financeiros contidos dos relatórios contábeis enviados à SEC e CVM. Valores dos gastos e benefícios ambientais não são citados por completo. Percebe-se que há um padrão, mas ainda em evolução. Pode-se dizer que as empresas ainda informam somente o exigido por leis e órgãos fiscalizadores. Não foram encontradas evidências de relatórios econômico-financeiro-ambientais.

    Full Text Available Today it is necessary to approach environmental topics with students in an interdisciplinary manner to mitigate the environmental damages that the Earth is suffering. In this paper we report an action-research and innovation study aimed at sensitizing students with respect to the care and preservation of the environment through the writing of short descriptive texts in English. The study had four stages: motivation, knowledge of ecological vocabulary, production of sentences and paragraphs, construction of short descriptive texts with the help of guidance questions and their publication in the school newspaper. The findings show that the procedure used in class promotes interdisciplinary work around environmental topics as well as the development of writing skills.Hoy en día, es necesario abordar temas ambientales con los estudiantes, de manera interdisciplinaria, para mitigar los daños ambientales que está sufriendo la tierra. En este artículo reportamos un estudio de investigación-acción e innovación que buscó sensibilizar a los estudiantes acerca del cuidado y la preservación del medio ambiente mediante la escritura de breves textos descriptivos en inglés. El estudio tuvo cinco etapas: motivación; conocimiento de vocabulario ecológico; producción de frases y párrafos; construcción de breves textos descriptivos -con la ayuda de preguntas orientadoras-, y la publicación de los textos en el periódico escolar. Los resultados muestran que el proceso empleado en clase promueve el trabajo interdisciplinario en torno a temas ecológicos, así como el desarrollo de habilidades escriturales.

    of the microeconomic theory in the aspects of the enterprise environmental management is verified thus, mainly for the fact that the environmental question currently influences directly the strategic planning of the organizations.A pesquisa que se segue objetiva apresentar certos fundamentos da microeconomia passíveis de aplicação e análise na gestão ambiental das empresas. Inicialmente realiza-se uma revisão sobre os conceitos e fundamentos microeconômicos, como a curva de possibilidade de produção, custos de poluição e de controle, benefícios e custos totais e marginais e teoria dos jogos; sendo, posteriormente, abordadas suas possíveis influências, inclusive com exercícios hipotéticos para compreensão da aplicabilidade dos fundamentos. Importante salientar que, na abordagem da teoria dos jogos, demonstra-se a justificativa da ação das agências reguladoras como órgãos de implementação de controles ambientais nas empresas. As ferramentas aqui abordadas são consideradas sob o aspecto teórico, mas permitem uma posterior aplicação nos processos gerenciais, na busca por tecnologias produtivas verdes e por certificações específicas. A pesquisa utiliza como metodologia o método dedutivo, buscando da teoria geral da microeconomia uma aplicação específica na gestão ambiental e, como procedimento técnico, utiliza a pesquisa bibliográfica. Verifica-se, assim, a consolidação da aplicabilidade da teoria microeconômica nos aspectos da gestão ambiental empresarial, principalmente pelo fato de que a questão ambiental atualmente influencia diretamente o planejamento estratégico das organizações.

Isto permitiria a construção de séries de novénios de distribuição espacial e temporal da característica que se pretenda estudar. Há nisto algumas semelhanças com abordagens dendrométricas, sendo que estas tendem a ser muito mais agressivas. Foi objectivo deste trabalho que numa fase inicial do estudo se procedesse à criação de uma maneira credível de fazer a quantificação de chumbo (II no felema da cortiça recorrendo a uma técnica de análise química nunca antes utilizada para este efeito – a voltametria. A escolha deste método da análise química moderna resulta do conhecimento das vantagens competitivas que tem sobre outros, quando aquele é aplicável, como se demonstra ser o caso. A metodologia utilizada começou por exigir a recolha de uma porção de cortiça de um sobreiro escolhido ao acaso, de maneira a encontrar o material cortiça como se encontra na árvore. No momento não se consideram possíveis correlações biogeográficas mas tão somente o material propriamente dito. Tendo sido possível fazer a quantificação indicada, estão em curso os estudos necessários à verificação da hipótese que dá o mote a este trabalho de investigação centrado no sobreiro do montado e do sobreiral, sendo que a principal conclusão a retirar é que a possibilidade de utilização do sobreiro como indicador da qualidade ambiental do local, neste caso quanto ao teor em Pb(II, é mais um serviço prestável (pelo ecossistema que orbita em torno do sobreiro às populações humanas da área da bacia mediterrânica ocidental.

    The purpose of the present work is to establish a methodology for assessing the sustainability of buildings in Mexico, which can be standardized and comparable with the rest of North America. For this purpose three building assessment systems in North America were first analyzed: (a) Leadership in Energy and Environmental Design (LEED), (b) Living Building Challenge (LBC); and (c) Energy Star for Buildings. In addition, the analysis included Spain's Green Building Council (GBCe), to have a different comparison point with the North American systems. The analysis of the four systems suggests the use of the Energy Star system due to the following reasons: 1) For all systems, the Energy Star system is the basis for comparison in terms of energy consumption and therefore emissions of greenhouse gases, 2) It is the system requiring the simplest description of the building (construction surface, occupancy and energy consumption) and does not require (unlike other systems) data on the location of the buildings, 3) For the LEED, LBC and GBCe systems, the evaluation must be performed by professionals accredited, while for the Energy Star certification is less restrictive A database of public buildings, managed by the Comision Nacional para el Uso Eficiente de la Energia (CONUEE), was used. It integrates a significant number of office buildings occupied by departments and agencies of the federal government in Mexico. This database holds information on annual energy consumption and area occupied. Such database was complemented with available information on Degree Day data provided by the Asociacion de Empresas para el Ahorro de Energia en la Edificacion (AEAEE); it allowed to include information on weather in the same terms as the proposed methodology by Energy Star system. From the analysis, some suggestions are presented below. First, it is suggested to strengthen the collection and integration of information related to commercial buildings in Mexico to implement a

    Contaminated sites by NAPL (Non-Aqueous Phase-Liquids) may lead to safety risks to human health and to ecosystems, restrictions to urban development and decrease of real estate value. This work used the radon gas as an indicator for the analysis of subsurface soil gas, once this noble gas presents good solubility in a wide range of NAPL, being partially retained in the NAPL contamination. Therefore, a decrease of the activity of radon in the contaminated soil gas can be expected, due to the high capacity of partitioning of radon in NAPL, which allows that the NAPL retain part of the radon previously available in the soil pores. The survey was carried out at a disused industry, contaminated by low volatile NAPL, located at southeast of Sao Paulo city, from June/14 to May/15. Radon was evaluated by passive detection methodology with CR-39 solid state nuclear track detectors (SSNTD) in ten monitoring stations installed in the contaminated area investigated and named 'A' to 'J'. Radon concentrations average for the eight monitoring stations at non-contaminated locations varied from (22 ± 4) kBq.m{sup -3} to (39 ± 4) kBq.m{sup -3} . For the two monitoring stations assumed as contaminated locations, radon concentrations average were (1.4 ± 0.4) kBq.m{sup -3} and (13 ± 9) kBq.m{sup -3}. The results have shown good agreement between the used method and the conventional environmental investigation techniques, for the majority of the monitoring stations in different seasons. Results obtained with CR-39 detectors varied over the exposure time due to the different seasons. No relation was observed between radon activity concentrations and rain volume accumulated over the different CR-39 exposure times. The lowest {sup 222}Rn activity concentrations occurred in 'G' and 'H' monitoring stations, also verifying by gamma-ray spectrometry, that the low activities are not related to the activity concentration of its father {sup 226}Ra from

    Clinch River-Environmental Restoration Program (CR-ERP) personnel and Tennessee Valley Authority (TVA) personnel conducted a study during the week of January 25--February 1, 1994. The organisms specified for testing were larval fathead minnows, Pimephales promelas, and the daphnid, Ceriodaphnia dubia. Surface water samples were collected from Clinch River Mile 9.0, Poplar Creek Mile 1.0, and Poplar Creek Mile 2.9 on January 24, 26, and 28. Samples were partitioned and provided to the CR-ERP and TVA toxicology laboratories for testing. Exposure of test organisms to these samples resulted in no toxicity (survival or growth) to fathead minnows; however, toxicity to daphnids was demonstrated in undiluted samples from Poplar Creek Mile 1.0 in testing conducted by TVA based on hypothesis testing of data. Point estimation (IC{sub 25}) analysis of the data, however, showed no toxicity in PCM 1.0 samples. Attachments to this report include: Chain of custody forms -- originals; Toxicity test bench sheets and statistical analyses; Meter calibrations; and Reference toxicant test information.

    The research work as presented in this article covers the design of detached breakwaters since they constitute a type of coastal defense work with which to combat many of the erosion problems found on beaches in a stable, sustainable fashion. The main aim of this work is to formulate a functional and environmental (non structural) method of design enabling the fundamental characteristics of a detached breakwater to be defined as a function of the effect it is wished to induce on the coast whilst meeting social demands and preserving or improving the quality of the littoral environment. The general applicability of the method is also sought by means of considering relations between variables od different natures (climatic, geomorphologic and geometric) influencing the changes experienced on the coast after the detached breakwater has been built. The study of the relations between the different variables is carried out on the data from a abase of nineteen actual, existing detached breakwaters on the Spanish Mediterranean coastline and follows a methodology based on the implementation of non-dimensional monomials and on a search for relations of dependency between them. Finally, a discussion on the results obtained lead to a proposal for a design method that uses some of the graphic relations found between the variables studied with which the aforesaid main objective is achieved.

    In August 2004, the corporative databank of the Brazilian Petroleum Agency included the records of 21,508 wells drilled in the country, of which 17,621 onshore. Evaluation of the suitability of well abandonment and decommissioning procedures in areas explored by the oil industry, particularly those lacking the legal protection by contracts signed with the Agency, has demanded the definition of priorities compatible with the limited human and financial resources. Excluding the wells covered by concession contracts in exploration blocks and production fields, 1,127 onshore wells still remained in the priority's list, of which 730 drilled from the 1920's through the 70's, 207 during the 80's, and 90 in the past decade until August 1998. In regard to the oldest 730 wells, all drilled in a period when environmental concerns were still irrelevant, and abandonment and decommissioning most likely inadequate, geo processing resources have been used to select the priority-determining criteria for evaluation of the various well groups. This work presents the methodology followed in the selection of the most critical cases. (author)

    The normative system directed to the conservation and protection of the environment, guaranteeing a sustainable use of the natural resources and controlling the contamination, has a relatively recent origin, in the middle of the XXth century, but it has experienced a very fast growth due to the awareness on the part of the citizens and the administrations, of the damage that the human being causes to the environment and the serious consequences that this implies and that are being seen more and more often. The international standards are mainly based on Agreements and Programs without no legal entailment. The legislative frame of the European Union is based on the Programs of Communitarian Action, the last one published is the VI Program. The regulation of the different sectors is performed through Directives, that constitute the base for each group of sectorial norms. Spain, as member state of the European Union, must incorporate and transpose the communitarian norms that are promulgated. The environmental sectors and matters in which it is legislated are very varied, which implyis the existence of a profuse sectorial legislation, difficult to handle and apply. Therefore, the correct application and fulfillment of this norms constitute one of the greatest challenges for the industries and companies. (Author)

    The impoundment of rivers for power generation leads to flooding of vast areas of land vegetation. Most submerged plants, die and enter into decomposition, releasing CO2 (carbon dioxide), CH4 (methane gas) into the air for many years. Scientists from around the world seek to clarify the processes to which these gases are submitted and their contributions to the process of global warming. Estimates suggest that the re-use of methane that passes through the turbines of these power plants could increase their energy potential by 75% and reduce their emissions of these gases by 65%, reducing their impact on global warming and resulting in carbon credits. To check the feasibility of using new processes and technologies to generate energy that recycles this biogas, operations for monitoring these biogases become routine tasks. The frequency is such that the exposure of humans to the risks of gas combustion, inherent to scenarios where these operations take place, becomes unacceptable. This motivates the use of robots in this activity. This paper presents the multi-mission platform Hybrid Environmental Robot, named 'Chico Mendes', as a tool for tracking gas emission and specially designed for flooded forest areas.
