    Scale, sludge and drilling mud from three geothermal fields (Bulalo, Philippines; Cerro Prieto, Mexico; and Dixie Valley, USA) containing As, Cu, Cr, Zn and Pb at levels above the earth's crustal abundance were studied for their environmental impact. Several techniques and procedures were used to assess the risk posed by the residues: whole rock analysis, X- ray diffraction, radioactivity counting, protocol leach tests, toxicity testing, accelerated weathering test and a preliminary acid mine dramage potential test. There was no evidence of toxicity or genotoxicity present in any of the samples tested. Leaching tests indicated that all of the wastes could be classified as non-hazardous. One sample showed a low-level radio activity but it was still within the occupational dose limit. Three samples tested positive for acidification potential while none of the regulated elements were found in the leachate after three months of weathering test

    The environmental implications of the changes in forestry operations and practices necessary to remove significant quantities of forest residues for use as a fuel were investigated in this study commissioned by the UK Department of Trade and Industry. The project involved: a review of current practices for the treatment of residues and the production of wood fuels in Great Britain; an assessment of the impact of these practices on soils, landscape, water, flora, fauna and air; and the modelling of scenarios to identify the quantity of forestry land from which residues could be obtained to help meet UK targets for the use of renewable energy. This allowed an assessment of how practices may develop and how environmental impacts may change as a result of increased removal of forestry residues. The study included a literature review, discussions with the forestry and biomass industries and the selection of case study areas with a range of soil types. Differences in opportunities for residue harvesting between upland forestry in the north and west of the UK and lowland forestry in the south of the UK were highlighted by the model outputs.

    Shortage of fuel wood has lead many rural people to switch to using agricultural residues as an alternative energy source. However this has not always been met with universal acclaim due to the role of residues as fertilisers. Although crop residues and animal manure as a nutrient source has been superseded by inorganic fertilizers in most intensive farming systems, they continue to be the main source of crop nutrient replacement in most developing countries. There has developed wide spread a...

    The environmental impact of meat is high mainly due to the feed required by livestock in combination with the impacts of cultivating, transporting and processing of feed crops such as tapioca and grains. Like regular feed crops, livestock also feed on residue from the food industry, such as pulp,

  6. Economic valuation of the environmental impact of logging residue recovery and nutrient compensation

    2000-01-01

    In this paper, the environmental impact of logging residue recovery (LRR) and nutrient compensation (NC) in Sweden is analysed and evaluated economically. Logging reside recovery and recirculation of wood ash can generate local environmental benefits, such as reduced soil acidification and, primarily in southern Sweden, also improved nitrogen balance and reduced nutrient leaching from forest land. Recovery of residues leads to a slight increase in net emissions of carbon dioxide, compared with on site decomposition, but this increase is small compared with the net emissions of carbon dioxide from fossil fuel cycles. The impact of toxic compounds is estimated to be insignificant, as is that on biodiversity, when current guidelines for forestry management methods are followed. The total cost, including direct costs and environmental costs/benefits, of LRR and NC is estimated to be about 1.1, 3.3 and 4.6 US dollars/GJ in southern, central and northern Sweden, respectively. For comparison, the current direct cost of LRR, excluding NC, is, on average, about 4.0 US dollars/GJ in Sweden. Almost one-third of the Swedish forest fuel potential is estimated to be located in the south, but this potential varies from about 50 to over 100 PJ per year depending on the assumptions made. Thus, when local environmental benefits are also considered, the overall economic benefit derived from the utilisation of forest fuels could increase significantly in southern Sweden, where large quantities of logging residues are available.

  7. Regulations and decisions in environmental impact assessment of residues radioactivity content

    Surveillance of natural radionuclides in the environment did not have high priority over many years compared to that of man-made radioactivity. There is, however, an increasing interest in such measurements since enhanced exposure to natural radioactivity is receiving the same legal weight as any other radiation exposure. In this context the surveillance of technologically enhanced naturally occurring materials, called TENORM becomes important. In Brazil, the industries of processing and chemical compounds production were developed based on mining, milling, transformation and manufacture of ores from sedimentary origin, ignea or metamorphic, which must determine the radioactive composition of the generated solid wastes and residues. Many solids residues stored in the environment has been of environmental concern facing the industries and environmentalists in Brazil as it presents a potential threat to the surrounding environment and to individuals occupationally exposed. Radiation protection regulations have not been applied yet to these industries, as the Brazilian regulatory agency (Comissao Nacional de Energia Nuclear - CNEN) has only recently published a regulatory guide concerning mining and milling of naturally occurring radioactive materials, which may generate enhanced concentrations of radionuclides. With respect to external and internal exposure to natural radionuclides from the solid residues storage, the nuclides of 232 Th, 235 U and 238 U decay chains are relevant, due to the exposure of workers as well as of members of the public. Radionuclides released from a source can be present as ions, molecules, complexes, mononuclear or polynuclear species, colloids, pseudocolloids, particles or fragments varying in size (nominal molecular mass), structure, morphology, density, valence and charge properties. One of the main points in environmental impact assessment is to identify whether the chemical availability is under influence of these speciation

  8. Environmental impacts of anaerobic digestion and the use of anaerobic residues as soil amendment

    1996-01-01

    This paper defines the environmental role of anaerobic digestion within the overall objective of recovering energy from renewable biomass resources. Examples and opportunities for incorporating anaerobic digestion into biomass-to-energy schemes are discussed, together with environmental aspects of anaerobic digestion plants. These include visual, public amenity, pathogens and public health, odor control, and gaseous emissions. Digestate disposal and the benefits of restrictions on recycling organic wastes and biomass residues back to the land are discussed, particularly as they relate to American and European codes of practice and environmental legislation. The paper concludes that anaerobic digestion, if performed in purpose-designed reactors that efficiently recover and use biogas, is an environmentally benign process that can enhance energy recovery and aid the beneficial land use of plant residues in many biomass-to-energy schemes.

    Highlights: • 110 French incinerators are compared with LCA based on plant-specific data. • Environmental impacts vary as a function of plants energy recovery and NO{sub x} emissions. • E.g. climate change impact ranges from −58 to 408 kg CO{sub 2}-eq/tonne of residual MSW. • Implications for LCA of waste management in a decision-making process are detailed. - Abstract: Incineration is the main option for residual Municipal Solid Waste treatment in France. This study compares the environmental performances of 110 French incinerators (i.e. 85% of the total number of plants currently in activity in France) in a Life Cycle Assessment perspective, considering 5 non-toxic impact categories: climate change, photochemical oxidant formation, particulate matter formation, terrestrial acidification and marine eutrophication. Mean, median and lower/upper impact potentials are determined considering the incineration of 1 tonne of French residual Municipal Solid Waste. The results highlight the relatively large variability of the impact potentials as a function of the plant technical performances. In particular, the climate change impact potential of the incineration of 1 tonne of waste ranges from a benefit of −58 kg CO{sub 2}-eq to a relatively large burden of 408 kg CO{sub 2}-eq, with 294 kg CO{sub 2}-eq as the average impact. Two main plant-specific parameters drive the impact potentials regarding the 5 non-toxic impact categories under study: the energy recovery and delivery rate and the NO{sub x} process-specific emissions. The variability of the impact potentials as a function of incinerator characteristics therefore calls for the use of site-specific data when required by the LCA goal and scope definition phase, in particular when the study focuses on a specific incinerator or on a local waste management plan, and when these data are available.

    Full Text Available The development of harvesting systems aims to provide physically feasible, economically viable, and environmentally sound solutions. Residual stand-damage data have been collected from a mixed broadleaved stand in Kheyrud area in Hyrcanian forest in the northern of Iran. After the harvesting operations, for all trees, damage to the bole, roots, extent of the damage, wounding patterns, size and distribution was assessed using stratified systematic sampling with a random start and fixed area plots. Results show that wounding occurred on 16.4% of the remaining trees, but the severity of wounding varied significantly by species. Forty-six percent of wounding for all species combined was considered as small size. The greatest average amount of damage, to a bole, occurred along the first 1m up from the ground and also within 3m of the skid trail centerline (86.4%. Gouges were present on 79% of all scars. The stratification of the study unit would effectively improve accuracy of stand damage surveys. Selection of the appropriate method for damage reduction to trees adjacent skid trails was crucial. According to the results, skidding damage cannot be completely avoided in practice. We suggest that the education and the entertainment of the foresters and workers in forest would be enhanced and the injuries could be explained before the harvesting to the workers. In such a way the damages would be less in the future.

    On the basis of the dynamic growth of biogas plants in Germany the fertilization with biogas residues has obtained an important role for recirculation of plant nutrients, particularly with regard to nitrogen. In this work the effect of N nutrition with biogas residues was assessed in a 3-year on-field trial conducted at four sites throughout Bavaria. The fertilizing effects were tested by varying rate and time of biogas residues application, using different application techniques and the addition of nitrification inhibitors on several crops. The biogas residues achieved mineral fertilizer equivalents of 30 - 45 %. Overall, the untreated biogas residues showed a slightly increased N efficiency compared to cattle manure, whereas particularly site-dependent differences resulted in large differences in N efficiency of biogas residues.

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

  15. Environmental impact of APC residues from municipal solid waste incineration: reuse assessment based on soil and surface water protection criteria.

    Waste management and environmental protection are mandatory requirements of modern society. In our study, air pollution control (APC) residues from municipal solid waste incinerators (MSWI) were considered as a mixture of fly ash and fine particulate solids collected in scrubbers and fabric filters. These are hazardous wastes and require treatment before landfill. Although there are a number of treatment options, it is highly recommended to find practical applications rather than just dump them in landfill sites. In general, for using a construction material, beyond technical specifications also soil and surface water criteria may be used to ensure environmental protection. The Dutch Building Materials Decree (BMD) is a valuable tool in this respect and it was used to investigate which properties do not meet the threshold criteria so that APC residues can be further used as secondary building material. To this end, some scenarios were evaluated by considering release of inorganic species from unmoulded and moulded applications. The main conclusion is that the high amount of soluble salts makes the APC residues a building material prohibited in any of the conditions tested. In case of moulding materials, the limits of heavy metals are complied, and their use in Category 1 would be allowed. However, also in this case, the soluble salts lead to the classification of "building material not allowed". The treatments with phosphates or silicates are able to solve the problem of heavy metals, but difficulties with the soluble salts are still observed. This analysis suggests that for APC residues to comply with soil and surface water protection criteria to be further used as building material at least a pre-treating for removing soluble salts is absolutely required.

    Fourteen beta-agonists were quantitatively analyzed in cattle, chicken and swine liver specimens purchased at 14 wet markets in Selangor State, Malaysia, by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The health risks of ractopamine and clenbuterol residues in the Malaysian population were assessed based on quantitative data and meat consumption statistics in Malaysia. Wastewater samples collected at swine farms (n = 2) and cattle/cow farms (n = 2) in the Kuala Langat district were analyzed for the presence for the 14 compounds. Wastewater in chicken farms was not collected because there was negligible discharge during the breeding period. The environmental impacts caused by beta-agonists discharged from livestock farms were spatially assessed in the Langat River basin using a geographic information system (GIS). As a result, 10 compounds were detected in the liver specimens. Ractopamine, which is a permitted compound for swine in Malaysia, was frequently detected in swine livers; also, 9 other compounds that are prohibited compounds could be illegally abused among livestock farms. The health risks of ractopamine and clenbuterol were assessed to be minimal as their hazard quotients were no more than 7.82 × 10 -4 and 2.71 × 10 -3 , respectively. Five beta-agonists were detected in the wastewater samples, and ractopamine in the swine farm resulted in the highest contamination (30.1 μg/L). The environmental impacts of the beta-agonists in the Langat River basin were generally concluded to be minimal, but the ractopamine contamination released from swine farms was localized in coastal areas near the estuary of the Langat River basin because most swine farms were located in that region.

  18. Long-term management of the existing radioactive wastes and residues at the Niagara Falls Storage Site. Draft Environmental Impact Statement

    International Nuclear Information System (INIS)

    1984-08-01

    The statement assesses and compares several alternatives for long-term management of the existing radioactive wastes and residues at the Niagara Falls Storage Site (NFSS), Lewiston, New York. The alternatives include: (1) no action (continued interim storage at NFSS within a diked and capped containment area), (2) long-term management at NFSS (improved containment, with or without modified form of the residues), (3) long-term management at other DOE sites (Hanford, Washington, or Oak Ridge, Tennessee), and (4) offsite management of the residues at Hanford or Oak Ridge and either leaving the wastes at NFSS or removing them for disposal in the ocean. In addition to alternatives analyzed in depth, several options are also considered, including: other modifications of residue form, modification of the basic conceptual designs, other containment design options, transportation routes, and transportation modes. The radiological health effects (primarily increased risk of cancer) associated with long-term management of the wastes and residues are expected to be smaller than the nonradiological risks of occupational and transportation-related injuries and deaths. During the action period, the risk is highest for workers if all wastes and residues are moved to Hanford. The risk is highest for the general public if the residues are moved to Hanford and the wastes are moved to the ocean. Dispersal of the slightly contaminated wastes in the ocean is not expected to result in any significant impacts on the ocean environment or pose any significant radiological risk to humans. For all alternatives, if controls ceased, there would be eventual dispersion of the radioactive materials to the environment. If it is assumed that all controls cease, predicted time for loss of covers over the buried materials ranges from several hundred years to more than two million years, depending on the use of the land surface

    The adoption of US-type environmental impact statements is considered to be approaching. Environmental impact statements are defined as comprehensive analyses of the future effects of measures on environmental conditions with the aim of avoiding ecological disadvantages. The recommendation ratified by the European Communities on June 27, 1985 requires the environmental impact statement to be implemented as a mandatory procedure. The implementation is difficult to realize. Particular problems consist in the alignment of the environmental impact statement with existing administrative procedures and in the operationable formulation of the aims and results of the statement. Paragraph 72 of the administrative procedures law (VwVfG) shows that planning procedures and environmental impact statement are to be treated as two parallel regulations. The structural order of environmental impact statements must therefore be integrated into the regulations of planning procedures. (orig./HP) [de

    Agricultural and forestry residues have been converted to energy for centuries. The technologies employed range from straightforward approaches such as combustion to produce heat to more involved approaches such as pyrolysis of the residues to produce medium-Btu synthetic gas, charcoal, and oil. Thus there is no one technology that can be characterized as the best or most promising for conversion of agricultural and forestry residues into energy. Therefore, to accurately assess the potential of agricultural and forestry residues as energy resources, an array of current conversion options should be addressed. Four conversion methods and five residues are examined in this report, which describes six model systems: hydrolysis of corn residues, pyrolysis of corn residues, combustion of cotton-ginning residues, pyrolysis of wheat residues, fermentation of molasses, and combustion of pulp and papermill wastes. Estimates of material and energy flows for those systems are given per 10/sup 12/ Btu of recovered energy. Regional effects are incorporated by addressing the regionalized production of the residues. A national scope cannot be provided for every residue considered because of the biological and physical constraints of crop production. Thus, regionalization of the model systems to the primary production region for the crop from which the residue is obtained has been undertaken. The associated environmental consequences of residue utilization are then assessed for the production region. In addition, the environmental impacts of operating the model systems ae examined. On the basis of estimates found in the literature, capital, operating, and maintenance cost estimates are given for the model systems. The study indicates that the most serious environmental impacts arise from residue removal rather than from conversion.

    Soils provide many basic ecosystem services for our society and most of these services are carried out by the soil communities, thus influencing soils quality. Soil organic matter (SOM) can be considered as one of the most important soil quality indices for it plays a determinant role in many physical, chemical and biological processes, such as soil structure and erosion resistance, cation exchange capacity, nutrient cycling and biological activity (Andrews et al., 2004). Since a long time, exogenous organic inputs are largely used for improving agricultural soils, affecting highly soil fertility and productivity. The use of organic amendments such as crop residues influences the soil microbial populations' diversity and abundance. In the meantime, soil microbial communities play a major role in the organic matter degradation, and the effect of different microbial communities on the decomposition of crop residues is not well documented. In this context, studying the impact of crop residues on soil microbial ecology and the processes controlling the fate of plant residues in different management practices is essential for understanding the long-term environmental and agronomic effects on soil and organic matters. Our purpose in the present work was to investigate the decomposition by two contrasting microbial communities of three crop residues, and compare the effect of different residues amendments on the abundance and function of each soil microbial communities. Among the main crops which produce large amounts of residues, we focused on three different plants: wheat (Triticum aestivum L.), rape (Brassica napus) and sunflower (Helianthus annuus). The residues degradation in two soils of different management practices and the microbial activity were evaluated by: microbial abundance (microbial carbon, culturable bacteria, total DNA, qPCR), in combination with functional indicators (enzymatic assays and Biolog substrate utilization), kinetics of C and N

    The Section is concerned with preparation of environmental statements and assessments and development of assessment methodologies for energy technologies. During 1976, activities involved nuclear, fossil, and geothermal energy; this work was supported by the U.S.Army, HUD, US ERDA, and US NRC. Two special studies--one on the effects of power plant intake structures on fish impingement and another on multiple uses of cooling lakes--were completed and should serve as references for future analyses. Two research projects sponsored by NRC--the Unified Transport Approach (UTA) to Power Plant Assessment and the Environmental Monitoring Data Evaluation Study--were continued. The purpose of the UA program is to develop fast-transient, one- and two-dimensional transport models for estimating thermal, radiological, chemical, and biological impacts in complicated water bodies. The impact of public use of various products that contain radioactive isotope is being evaluated. The Environmental Impact Sections assistance to NRC expanded to include assessments of fuel-fabrication facilities being considered for relicensing and two uranium in-situ solution mining facility proposals. The work for HUD comprises an assessment of the first application of MIUS in a new town development. A generic environmental statement was prepared and an environmental monitoring program for the facility was designed

    Residual environmental sound can mask intrusive4 (unwanted) sound. It is a factor that can affect noise impacts and must be considered both in noise-impact studies and in noise-mitigation designs. Models for quantitative prediction of sensation level (audibility) and psychological effects of intrusive noise require an input with 1/3 octave-band spectral resolution of environmental masking noise. However, the majority of published residual environmental masking-noise data are given with either octave-band frequency resolution or only single A-weighted decibel values. A model has been developed that enables estimation of 1/3 octave-band residual environmental masking-noise spectra and relates certain environmental parameters to A-weighted sound level. This model provides a correlation among three environmental conditions: measured residual A-weighted sound-pressure level, proximity to a major roadway, and population density. Cited field-study data were used to compute the most probable 1/3 octave-band sound-pressure spectrum corresponding to any selected one of these three inputs. In turn, such spectra can be used as an input to models for prediction of noise impacts. This paper discusses specific algorithms included in the newly developed computer program ENMASK. In addition, the relative audibility of the environmental masking-noise spectra at different A-weighted sound levels is discussed, which is determined by using the methodology of program ENAUDIBL.

    Geothermal utilization can cause surface disturbances, physical effects due to fluid withdrawal noise, thermal effects and emission of chemicals as well as affect the communities concerned socially and economically. The environmental impact can be minimized by multiple use of the energy source and the reinjection of spent fluids. The emission of greenhouse gases to the atmosphere can be substantially reduced by substituting geothermal energy for fossil fuels as an industrial energy source wherever possible

    This report was originally published as an appendix to the draft U.S. Nuclear Regulatory Commission (NRC) document entitled, open-quotes Generic Environmental Impact Statement in Support of Rulemaking on Radiological Criteria for Decommissioning of NRC-Licensed Nuclear Facilities.close quotes Because of the great interest in this report by members of the public, citizen and environmental organizations, academicians, licensees, and regulators, the NRC staff is publishing this report separately, so that it can be readily available to a diverse audience. This report was created to assist both the NRC staff and interested members of the public in evaluating background radiation (background) as a decommissioning criterion, by serving as a primer on background and providing information on the existing applications of background in regulatory criteria and standards. This report also discusses some of the methods available to measure and distinguish between the very low radiation levels associated with background and man-made sources of radiation. Two approaches are considered for applying background as a decommissioning criterion; these are the use of background dose rates and background radionuclide concentrations. This report concludes that the temporal and spatial variability of background produces a wide range of doses to United States residents, which prevents the application of background dose rates as a decommissioning criterion. Instead, this report recommends that local background radionuclide concentrations serve as a benchmark for decommissioning criteria, while taking into account the concept of reducing residual radioactivity to a level as low as is reasonably achievable

    Tobacco is an important cash crop in Pakistan. It is a sensitive plant, prone to bacterial, fungal and viral diseases. Therefore, high levels of pesticides are used to grow tobacco. Many of these pesticides are highly toxic and have profound impacts not only on the smokers but also on the lives of tobacco farmers, their families and the environment. The environmental impacts of tobacco crop start right from its seedlings stage till throwing away of cigarette filters. These impacts are divided into three stages: (a) Environmental impacts at the tobacco growing stage, (b) Environmental impacts at tobacco manufacturing/processing stage, and (c) Environmental impacts of the tobacco use. This paper provides information of environmental impacts of tobacco crop at all the above-mentioned three stages and recommends measures for mitigation. (author)

  10. Environmental Accounting Evidence in Organic Solid Residue Treatment Companies

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available The growing concern with natural resources and the environment brings out the true dimension of these issues. The awareness of society causes companies to adopt environmentally correct policies and attitudes, so as to contribute with the preservation of the environment. Accounting, as a social science which studies the patrimony and its affectations, has adapted to the need of its users and has started to care about proper presentation and measurement of environmental items, for effective publication to society. With this premise, this study aims to identify and describe the contributions of Environmental Accounting to the process of environmental accounting disclosure of a company, which deals with organic solid residues from agriculture. Using a case study, it has been intended to analyze the production process and to list the environmental items and events that could benefit the company through their disclosure. It was intended, with this study, to highlight the contribution that the environmental accounting may add to the company, with proper measurement and presentation proposals. We have been able to verify that, indeed, there are events of an environmental nature resulting from the production process and also of the investment that it carries out periodically to preserve nature; however, there re faults in the accounting records from an environmental point of view. The application of environmental accounting in the organization allows for a broad view of environmental management and sustainable development adopted by the entity, registering all events that may generate economic and financial changes.

  18. Improving post-detonation energetics residues estimations for the Life Cycle Environmental Assessment process for munitions.

    2018-03-01

    The Life Cycle Environmental Assessment (LCEA) process for military munitions tracks possible environmental impacts incurred during all phases of the life of a munition. The greatest energetics-based emphasis in the current LCEA process is on manufacturing. A review of recent LCEAs indicates that energetics deposition on ranges from detonations and disposal during training is only peripherally examined through assessment of combustion products derived from closed-chamber testing or models. These assessments rarely report any measurable energetic residues. Field-testing of munitions for energetics residues deposition has demonstrated that over 30% of some energetic compounds remain after detonation, which conflicts with the LCEA findings. A study was conducted in the open environment to determine levels of energetics residue deposition and if combustion product results can be correlated with empirical deposition results. Energetics residues deposition, post-detonation combustion products, and fine aerosolized energetics particles following open-air detonation of blocks of Composition C4 (510 g RDX/block) were quantified. The deposited residues amounted to 3.6 mg of energetic per block of C4, or less than 0.001% of the original energetics. Aerial emissions of energetics were about 7% of the amount of deposited energetics. This research indicates that aerial combustion products analysis can provide a valuable supplement to energetics deposition data in the LCEA process but is insufficient alone to account for total residual energetics. This study demonstrates a need for the environmental testing of munitions to quantify energetics residues from live-fire training. Published by Elsevier Ltd.

  19. Environmental impact assessment screening tool

    International Nuclear Information System (INIS)

    1995-05-01

    An environmental assessment and impact planning software, SCREENER, was tested at a pilot project at the Cameco site (Port Hope). SCREENER was used to screen the impacts of a new construction project in accordance with the process and reporting requirements laid out in the Canadian Environmental Assessment Act. The software test concentrated on the activities that are directly involved with the structure construction and site preparation activities. In addition, a two and one half day training course was given to three AECB staff using the test case as a hands on example. The conclusion of this project is that an automated tool such as SCREENER (or Calyx, the new generation of environmental assessment tools from ESSA Software Ltd.), will help the AECB to standardize the approach to environmental assessment, assist in project planning, and save resources in the screening process. The new approach could allow to allocate AECB limited resources to the detailed assessments required for maximum impact activities

  20. Environmental insecticide residues from tsetse fly control measures in Uganda

    International Nuclear Information System (INIS)

    Sserunjoji-Sebalija, J.

    1976-01-01

    Up to June 1974 areas in Uganda totalling 8600km 2 have been successfully reclaimed from tsetse fly infestation by ground spray of 3% dieldrin water emulsions. A search for equally effective but less persistent and toxic compounds against tsetse flies has been unsuccessful. Fourteen insecticide formulations have been tested for their persistence on tree bark surfaces and, therefore, their availability and toxicity to the target tsetse flies. Only those compounds with a high immediate insecticidal activity (some higher than dieldrin) like endosulfan, Chlorfenvinphos and propoxur could merit further consideration in tsetse control. While some were toxic to tsetse as fresh deposits, they lacked sufficient persistence. A study of the environmental implication from the continued use of the highly persistent and toxic dieldrin has provided useful data on residues likely to be found both in terrestrial and aquatic fauna and flora. These are generally low. Moreover, there is evidence of degradation in some fish species (Protopterus aethiopicus and Clarias). Also, dilution factors and adsorption involving the muddy nature of water run-off, etc., and controlled burning of grasses after tsetse eradication would tend to inactivate the residual insecticide and protect aquatic systems. The general findings have indicated less risk than anticipated of the environmental contamination from tsetse control by application of persistent and toxic insecticides. (author)

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

  6. Debris and meteoroid proportions deduced from impact crater residue analysis

    1995-01-01

    This study is a further investigation of space-exposed samples recovered from the LDEF satellite and the Franco-Russian 'Aragatz' dust collection experiment on the Mir Space Station. Impact craters with diameters ranging from 1 to 900 micron were found on the retrieved samples. Elemental analysis of residues found in the impact craters was carried out using Energy Dispersive X-ray spectrometry (EDX). The analyses show evidence of micrometeoroid and orbital debris origins for the impacts. The proportions of these two components vary according to particle size and experimental position with respect to the leading edge of the spacecraft. On the LDEF leading edge 17 percent of the impacts were apparently caused by micrometeoroids and 11 percent by debris; on the LDEF trailing edge 23 percent of the impacts are apparently caused by micrometeoroids and 4 percent consist of debris particles - mostly larger than 3 micron in diameter - in elliptical orbits around the Earth. For Mir, the analyses indicate that micrometeoroids form 23 percent of impacts and debris 9 percent. However, we note that 60-70 percent of the craters are unidentifiable, so the definitive proportions of natural v. man-made particles are yet to be determined. Experiments carried out using a light gas gun to accelerate glass spheres and fragments demonstrate the influence of particle shape on crater morphology. The experiments also show that it is more difficult to analyze the residues produced by an irregular fragment than those produced by a spherical projectile. If the particle is travelling above a certain velocity, it vaporizes upon impact and no residues are left. Simulation experiments carried out with an electrostatic accelerator indicate that this limit is about 14 km/s for Fe particles impacting Al targets. This chemical analysis cut-off may bias interpretations of the relative populations of meteoroid and orbital debris. Oblique impacts and multiple foil detectors provide a higher likelihood

    Highlights: • A dynamic LCA is proposed considering time-varying factors. • Dynamic LCA is used to highlight GHG emission hotspots of gasification projects. • Indicators are proposed to reflect GHG emission performance. • Dynamic LCA alters the static LCA results. • Crop residue gasification project has high GHG abatement potential. - Abstract: Bioenergy from crop residues is one of the prevailing sustainable energy sources owing to the abundant reserves worldwide. Amongst a wide variety of energy conversion technologies, crop residue gasification has been regarded as promising owing to its higher energy efficiency than that of direct combustion. However, prior to large-scale application of crop residue gasification, the lifetime environmental performance should be investigated to shed light on sustainable strategies. As traditional static life cycle assessment (LCA) does not include temporal information for dynamic processes, we proposed a dynamic life cycle assessment approach, which improves the static LCA approach by considering time-varying factors, e.g., greenhouse gas characterization factors and energy intensity. As the gasification project can reduce greenhouse gas (GHG) discharge compared with traditional direct fuel combustion, trade-offs between the benefits of global warming mitigation and the impact on global warming of crop residue gasification should be considered. Therefore, indicators of net global warming mitigation benefit and global warming impact mitigation period are put forward to justify the feasibility of the crop residue gasification project. The proposed dynamic LCA and indicators were then applied to estimate the life cycle global warming impact of a crop residue gasification system in China. Results show that the crop residue gasification project has high net global warming mitigation benefit and a short global warming impact mitigation period, indicating its prominent potential in alleviating global warming impact.

    1977-01-01

    An analysis and evaluation of the ecological monitoring program at the Surry Nuclear Power Plant showed that predictions of potential environmental impact made in the Final Environmental Statement (FES), which were based on generally accepted ecological principles, were not completely substantiated by environmental monitoring data. The Surry Nuclear Power Plant (Units 1 and 2) was chosen for study because of the facility's relatively continuous operating history and the availability of environmental data adequate for analysis. Preoperational and operational fish monitoring data were used to assess the validity of the FES prediction that fish would congregate in the thermal plume during winter months and would avoid the plume during summer months. Analysis of monitoring data showed that fish catch per unit effort (CPE) was generally high in the thermal plume during winter months; however, the highest fish catches occurred in the plume during the summer. Possible explanations for differences between the FES prediction and results observed in analysis of monitoring data are discussed, and general recommendations are outlined for improving impact assessment predictions

  11. Research gaps related to the environmental impacts of electronic cigarettes

    2014-01-01

    Objective To consider the research gaps related to the environmental impacts of electronic cigarettes due to their manufacture, use and disposal. Methods Literature searches were conducted through December 2013. Studies were included in this review if they related to the environmental impacts of e-cigarettes. Results Scientific information on the environmental impacts of e-cigarette manufacturing, use and disposal is very limited. No studies formally evaluated the environmental impacts of the manufacturing process or disposal of components, including batteries. Four studies evaluated potential exposure to secondhand e-cigarette aerosol, an indication of impacts on indoor air quality. A 2010 survey of six e-cigarette models found that none of the products provided disposal instructions for spent cartridges containing nicotine. Notably, some e-cigarette manufacturers claim their e-cigarettes are ‘eco-friendly’ or ‘green’, despite the lack of any supporting data or environmental impact studies. Some authors argue that such advertising may boost sales and increase e-cigarette appeal, especially among adolescents. Conclusions Little is known about the environmental impacts of e-cigarettes, and a number of topics could be further elucidated by additional investigation. These topics include potential environmental impacts related to manufacturing, use and disposal. The environmental impacts of e-cigarette manufacturing will depend upon factory size and the nicotine extracting method used. The environmental impacts of e-cigarette use will include chemical and aerosol exposure in the indoor environment. The environmental impacts of disposal of e-cigarette cartridges (which contain residual nicotine) and disposal of e-cigarettes (which contain batteries) represent yet another environmental concern.

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

    2013-01-01

    Highlights: • Impact loading reduces the torsional strength of composite shaft. • Impact energy level determines the severity of torsional strength reduction. • Hybrid composite shafts can be manufactured by mixing two types of filament. • Maximum torque capacity of shafts can be estimated using finite element method. - Abstract: This paper presents an experimental and numerical study to investigate residual torsional properties of composite shafts subjected to impact loadings. E-glass/epoxy, carbon/epoxy and E-glass–carbon/epoxy hybrid composite shafts were manufactured by filament winding method. Composite shafts were impacted at 5, 10, 20 and 40 J energy levels. Force–time and energy–time histories of impact tests were recorded. One composite shaft with no impact, and four composite shafts with impact damage, five in total, were tested under torsion. Torque-twisting angle relations for each test were obtained. Reduction at maximum torque and maximum twisting angle induced by impact loadings were calculated. While 5 J impact did not cause significant reduction at maximum torque and maximum twisting angle, remaining impact loadings caused 34–67% reduction at maximum torque, and 30–61% reduction at maximum twisting angle. Reductions increased with increasing energy levels and varied depending on the material of composite shafts. The 3-D finite element (FE) software, Abaqus, incorporated with an elastic orthotropic model, was then used to simulate the torsion tests. Good agreement between experimental and numerical results was achieved

    1977-07-01

    This environmental impact assessment (EIA) addresses the expected programmatic activities of the Geopressure Subprogram of the Division of Geothermal Energy. The goal of the Geopressure Subprogram is to stimulate development of geopressured resources as an economic, reliable, operationally safe, and environmentally acceptable energy source. The subprogram includes activities in the areas of engineering research and development; resource exploration, assessment, and development; resource utilization including pilot and demonstration facilities; and environmental research and control technology development. It should be recognized that most of the subprogram activities extend over several years and are in their early stages of implementation at this time. The zones of potential geopressure development are in the region located along the Texas and Louisiana Gulf Coasts extending up to 200 miles (300 km) inland. Geopressured zones are sedimentary basins where water is trapped at high pressures within or below thick, nearly impermeable shale sequences. The confined water supports most or all of the weight of the overburden. This inhibits sediment compaction and causes formation pore pressure to exceed hydrostatic pressure. in sedimentary basins that are underlain by thin oceanic crust, upward thermal conduction from the mantle heats geopressured fluids and sediments to abnormally high temperatures, often in excess of 260 C (500 F).

  1. Environmental assessment of post-consumer wood and forest residues gasification: The case study of Barcelona metropolitan area

    International Nuclear Information System (INIS)

    Puy, Neus; Rieradevall, Joan; Bartroli, Jordi

    2010-01-01

    An energy and environmental analysis of post-consumer wood and forest residues gasification in metropolitan areas is carried out to determine the most critical stages of their life cycle. Life Cycle Impact Assessment (LCIA) methodology is used to identify the environmental load of three defined scenarios: (1) Post-consumer wood from recycling points; (2) Post-consumer wood from bulky wastes; and (3) Forest residues. The stages considered are biomass pre-treatment, transport and gasification. Biomass pre-treatment comprise different steps: separation, chipping, sifting, post-chipping for all the scenarios; except for the drying step which is only entailed to Scenario 3. The midpoint impact categories taken into account are: abiotic depletion (AD), global warming (GW), ozone layer depletion (ODP), human toxicity (HT), acidification (A) and eutrophication (E). Results show that, due to the high physical requirements for biomass gasification, the most appropriate biomass is that of Scenario 1, since forest residues require a drying stage, which involves high energy consumption and high environmental impact. Energy consumption in biomass pre-treatment and transport stages is low compared to the energy obtained from gasification, which represents the 5% in Scenario 1; 7% in Scenario 2; and 13% in Scenario 3.

    An energy and environmental analysis of post-consumer wood and forest residues gasification in metropolitan areas is carried out to determine the most critical stages of their life cycle. Life Cycle Impact Assessment (LCIA) methodology is used to identify the environmental load of three defined scenarios: (1) Post-consumer wood from recycling points; (2) Post-consumer wood from bulky wastes; and (3) Forest residues. The stages considered are biomass pre-treatment, transport and gasification. Biomass pre-treatment comprise different steps: separation, chipping, sifting, post-chipping for all the scenarios; except for the drying step which is only entailed to Scenario 3. The midpoint impact categories taken into account are: abiotic depletion (AD), global warming (GW), ozone layer depletion (ODP), human toxicity (HT), acidification (A) and eutrophication (E). Results show that, due to the high physical requirements for biomass gasification, the most appropriate biomass is that of Scenario 1, since forest residues require a drying stage, which involves high energy consumption and high environmental impact. Energy consumption in biomass pre-treatment and transport stages is low compared to the energy obtained from gasification, which represents the 5% in Scenario 1; 7% in Scenario 2; and 13% in Scenario 3. Biomass pre-treatment is associated to an important contribution in AD and ODP impact categories, calculated as 71% and 98% of the overall impact. The transport stage is of no significant influence either in the scenarios or in the impact categories (less than 24% of the overall impact). Finally, gasification represents an impact of 3-78% of the different impact categories. (author)

    Indian society today is concerned about the health and environmental risks of technologies. The major environmental issues of concern for technologies available for electricity generation are air emissions, management of wastes generated and land requirements. The production of electricity in India is primarily composed of a mix of thermal and hydroelectric power plants with nuclear energy currently contributing to an extent of slightly above 2.0%. For maintaining a decent living standard the present electricity generation has to be increased manifold and with the existing commercially available technologies this can lead to a greater impact on the environment in the immediate vicinity of plant unless a judicious mix is chosen. India which hardly contributed 1 of the global pollution in the year 1950 contributes about 20% now and with the growth in electricity generation its contribution will also be slightly increasing and hence environment will have to be one of the guiding factors in future choice of technologies for the growth of electric power generation. Indian coal has a very high ash content (30 - 50 %) and hence the fly ash problem in India can be severe. During the year 1993-94 approximately 33 million tonnes of fly ash was generated in India from the coal fired thermal power stations. The land requirement for disposal of this ash is continuously increasing. The disposal of fly ash near water bodies will also create difficulties as in addition to radionuclides, toxic trace elements may also get washed out. Pollution from the use of coal will have a definite effect on the environment in addition to depletion of the energy source

    Environmental protection is critical to maintain ecosystem services essential for human well-being. It is important to be able to rank countries by their environmental impact so that poor performers as well as policy 'models' can be identified. We provide novel metrics of country-specific environmental impact ranks - one proportional to total resource availability per country and an absolute (total) measure of impact - that explicitly avoid incorporating confounding human health or economic indicators. Our rankings are based on natural forest loss, habitat conversion, marine captures, fertilizer use, water pollution, carbon emissions and species threat, although many other variables were excluded due to a lack of country-specific data. Of 228 countries considered, 179 (proportional) and 171 (absolute) had sufficient data for correlations. The proportional index ranked Singapore, Korea, Qatar, Kuwait, Japan, Thailand, Bahrain, Malaysia, Philippines and Netherlands as having the highest proportional environmental impact, whereas Brazil, USA, China, Indonesia, Japan, Mexico, India, Russia, Australia and Peru had the highest absolute impact (i.e., total resource use, emissions and species threatened). Proportional and absolute environmental impact ranks were correlated, with mainly Asian countries having both high proportional and absolute impact. Despite weak concordance among the drivers of environmental impact, countries often perform poorly for different reasons. We found no evidence to support the environmental Kuznets curve hypothesis of a non-linear relationship between impact and per capita wealth, although there was a weak reduction in environmental impact as per capita wealth increases. Using structural equation models to account for cross-correlation, we found that increasing wealth was the most important driver of environmental impact.

    This Environmental Impact Statement (EIS) provides as much information as possible at this stage of the project development regarding the potential environmental impacts of the proposed construction and operation of a Superconducting Super Collider (SSC) at each of the site alternatives. However, the DOE recognizes that further review under the National Environmental Policy Act (NEPA) is required prior to construction and operation of the proposed SSC project at the selected site based on more detailed design and to identify specific mitigation measures which can be incorporated into final design. Accordingly, following selection of a site for the proposed SSC, the DOE will prepare a Supplemental EIS to address in more detail the impacts of constructing and operating the proposed SSC at the selected site and alternatives for mitigating those impacts. To measure the effects of constructing the SSC at any of the seven alternative sites, the DOE determined which aspects of the human environment would be significantly affected. The EIS describes the baseline conditions at each of the seven site alternatives, the trends underway resulting in changes, the potential environmental impacts expected if the SSC were sited, possible mitigations of adverse impacts, and resulting residual adverse impacts

    Climate change adaptation reduces adverse effects of climate change but may also have undesirable environmental impacts. However, these impacts are yet poorly defined and analysed in the existing literature. To complement this knowledge-gap, we reviewed the literature to unveil the relationship between climate change adaptation and environmental impact assessment, and the degree to which environmental impacts are included in climate change adaptation theory and practice. Our literature review showed that technical, social and economic perspectives on climate change adaptation receive much more attention than the environmental perspective. The scarce interest on the environmental impacts of adaptation may be attributed to (1) an excessive sectoral approach, with dominance of non-environmental perspectives, (2) greater interest in mitigation and direct climate change impacts rather than in adaptation impacts, (3) a tendency to consider adaptation as inherently good, and (4) subjective/preconceived notions on which measures are good or bad, without a comprehensive assessment. Environmental Assessment (EA) has a long established history as an effective tool to include environment into decision-making, although it does not yet guarantee a proper assessment of adaptation, because it is still possible to postpone or even circumvent the processes of assessing the impacts of climate adaptation. Our results suggest that there is a need to address adaptation proactively by including it in EA, to update current policy frameworks, and to demand robust and reliable evaluation of alternatives. Only through the full EA of adaptation measures can we improve our understanding of the primary and secondary impacts of adaptation to global environmental change. - Highlights: • Climate change adaptation may have undesirable environmental impacts. • The impacts of adaptation are yet poorly analysed in the literature. • There is an excessive sectoral approach to adaptation, mainly

  16. Crop residue recycling for economic and environmental sustainability: The case of India

    Directory of Open Access Journals (Sweden)

    Devi Saroj

    2017-09-01

    Full Text Available India is one of the key producers of food grain, oilseed, sugarcane and other agricultural products. Agricultural crops generate considerable amounts of leftover residues, with increases in food production crop residues also increasing. These leftover residues exhibit not only resource loss but also a missed opportunity to improve a farmer’s income. The use of crop residues in various fields are being explored by researchers across the world in areas such as textile composite non-woven making processes, power generation, biogas production, animal feed, compost and manures, etc. The increasing trend in addition of bio-energy cogeneration plants, increasing demand for animal feedstock and increasing trend for organic agriculture indicates a competitive opportunity forcrop residue in Agriculture. It is to be noted that the use of this left over residue isoften not mutually exclusive which makes measurement of its economic value more difficult.For example, straw can be used as animal bedding and thereafter as a crop fertilizer. In view of this, the main aim of this paper envisaged to know about how much crop residue is left unutilized and how best they can be utilized for alternative purposes for environmental stewardship and sustainability. In this context, an attempt has been made to estimate the total crop residue across the states and its economic value though data available from various government sources and a SWOT analysis performed for possible alternative uses of residue in India. This paper also discusses the successful case studies of India and global level of use of crop residues in economic activities. Over all 516 Mtonnes of crop residue was produced in 2014-15 in India among which cereals were the largest producer of crop residue followed by sugarcane. The energy potential from paddy rice straw crop residue was estimated as 486,955 megawatt for 2014-15 and similarly for coarse cereals it was 226,200megawatt.

  17. Environmental impacts of biomass energy resource production and utilization

    International Nuclear Information System (INIS)

    Easterly, J.L.; Dunn, S.M.

    1995-01-01

    The purpose of this paper is to provide a broad overview of the environmental impacts associated with the production, conversion and utilization of biomass energy resources and compare them with the impacts of conventional fuels. The use of sustainable biomass resources can play an important role in helping developing nations meet their rapidly growing energy needs, while providing significant environmental advantages over the use of fossil fuels. Two of the most important environmental benefits biomass energy offers are reduced net emissions of greenhouse gases, particularly CO 2 , and reduced emissions of SO 2 , the primary contributor to acid rain. The paper also addresses the environmental impacts of supplying a range of specific biomass resources, including forest-based resources, numerous types of biomass residues and energy crops. Some of the benefits offered by the various biomass supplies include support for improved forest management, improved waste management, reduced air emissions (by eliminating the need for open-field burning of residues) and reduced soil erosion (for example, where perennial energy crops are planted on degraded or deforested land). The environmental impacts of a range of biomass conversion technologies are also addressed, including those from the thermochemical processing of biomass (including direct combustion in residential wood stoves and industrial-scale boilers, gasification and pyrolysis); biochemical processing (anaerobic digestion and fermentation); and chemical processing (extraction of organic oils). In addition to reducing CO 2 and SO 2 , other environmental benefits of biomass conversion technologies include the distinctly lower toxicity of the ash compared to coal ash, reduced odours and pathogens from manure, reduced vehicle emissions of CO 2 , with the use of ethanol fuel blends, and reduced particulate and hydrocarbon emissions where biodiesel is used as a substitute for diesel fuel. In general, the key elements for

    Graham, R.L.

    1994-01-01

    The objective of this paper is to present a broad overview of the potential environmental impacts of biomass energy from energy crops. The subject is complex because the environmental impact of using biomass for energy must be considered in the context of alternative energy options while the environmental impact of producing biomass from energy crops must be considered in the context of the alternative land-uses. Using biomass-derived energy can reduce greenhouse gas emissions or increase them; growing biomass energy crops can enhance soil fertility or degrade it. Without knowing the context of the biomass energy, one can say little about its specific environmental impacts. The primary focus of this paper is an evaluation of the environmental impacts of growing energy crops. I present an approach for quantitatively evaluating the potential environmental impact of growing energy crops at a regional scale that accounts for the environmental and economic context of the crops. However, to set the stage for this discussion, I begin by comparing the environmental advantages and disadvantages of biomass-derived energy relative to other energy alternatives such as coal, hydropower, nuclear power, oil/gasoline, natural gas and photovoltaics

    Environmental impact assessment estimates the impact of development as a business unit and establishes mitigation plan. If the development is done, its economic effects can spread to the nearby areas. So that various developments can be distributed at different time intervals. The impact of the new developments can be combined with existing environmental impacts and can have a larger impact. That is, Cumulative impact assessment is needed to consider the environmental capacity of the Nearby area. Cumulative impact assessments require policy tools such as environmental impact assessment information and cumulative impact estimation models. In Korea, environmental information (water quality, air quality, etc.) of the development site is measured for environmental impact assessment and monitored for a certain period (generally 5 years) after the project. In addition, by constructing the environmental information as a spatial database, it is possible to express the environmental impact on a regional basis spatially and to intuitively use it for development site selection. Utilizing a composite model of environmental impact assessment information and Remote Sensing data for cumulative impact estimation, That can be used as a policy decision support tool that provides quantitative information for development area management, such as time series effect and sprawl phenomenon.

    In the U.S., coal fired power plants produce over 136 million tons of coal combustion residuals (CCRs) annually. CCRs are enriched in toxic elements, and their leachates can have significant impacts on water quality. Here we report the boron and strontium isotopic ratios of leaching experiments on CCRs from a variety of coal sources (Appalachian, Illinois, and Powder River Basins). CCR leachates had a mostly negative δ(11)B, ranging from -17.6 to +6.3‰, and (87)Sr/(86)Sr ranging from 0.70975 to 0.71251. Additionally, we utilized these isotopic ratios for tracing CCR contaminants in different environments: (1) the 2008 Tennessee Valley Authority (TVA) coal ash spill affected waters; (2) CCR effluents from power plants in Tennessee and North Carolina; (3) lakes and rivers affected by CCR effluents in North Carolina; and (4) porewater extracted from sediments in lakes affected by CCRs. The boron isotopes measured in these environments had a distinctive negative δ(11)B signature relative to background waters. In contrast (87)Sr/(86)Sr ratios in CCRs were not always exclusively different from background, limiting their use as a CCR tracer. This investigation demonstrates the validity of the combined geochemical and isotopic approach as a unique and practical identification method for delineating and evaluating the environmental impact of CCRs.

    Highlights: • Animal by-products use for electricity generation is investigated as a case-study. • Different methodological approaches to deal with by-products are explored in LCA. • Adopting a holistic perspective is crucial to achieve a circular economy framework. - Abstract: The food processing industry continues to grow, generating large amount of organically rich waste flows per year: these processors face significant economic and environmental pressures for appropriate conversion and disposal of these waste flows. Solid waste disposal problems, mostly in highly urbanized environments, energy shortages (primarily oil) and/or high petroleum prices, as well as environmental issues such as the shrinking landfill capacity, can all be addressed by converting waste material into useful and saleable products. This paper brings to the attention a possible strategy in order to meet the general EU directives concerning the residues utilization and percentage contribution for the total energy consumption by 2020, by evaluating the use of animal by-products (category 3, as defined in the directive 2002/1774/EC) for energy purposes. Slaughterhouse waste represents an important potential source of renewable energy: on average, 40–50% of a live animal is waste, with a potential energy content close to diesel fuel. Treatment of animal waste from slaughterhouse and the subsequent conversion to electricity is investigated as a case study in the Campania Region (Italy): the animal waste undergoes a rendering process, to separate a protein-rich fraction useful for animal meal production and a fat-rich fraction, to be combusted in a diesel engine for power and heat generation (CHP). An environmental assessment of the entire process is performed by means of LCA, providing a quantitative understanding of the plant processing. The study aims to understand to what extent electricity production from animal fat is environmentally sound and if there are steps and/or components

  18. Potential soil quality impact of harvesting crop residues for bio fuels

    International Nuclear Information System (INIS)

    Karlen, D.

    2011-01-01

    We are in one of the greatest technological, environmental and social transitions since the industrial revolution, as we strive to replace fossil energy with renewable biomass resources. My objectives are to (1) briefly review increased public interest in harvesting crop residues as feedstock for bio energy, (2) discuss the work soil scientists must do to address those interests, and (3) examine how soil quality assessment can be used to help quantify soil biological, chemical and physical response to this transition. Rising global energy demand, dependence on unstable imports, volatility in price, and increasing public concern regarding fossil fuel combustion effects on global climate change are among the factors leading to an increased interest in development and use of renewable biomass sources for energy production. Although controlling soil erosion by wind and water is no less important than in the past, it is not the only factor that needs to be considered when evaluating the sustain ability of land management practices including harvest of crop residues as bio energy feedstock. The concept of soil quality assessment is reviewed and the Soil Management Assessment Framework (SMAF) is used to illustrate how such assessments can be used for assessing impacts of harvesting crop residue as feedstock for bio energy production. Preliminary results of the SMAF assessment show that soil organic carbon (SOC) is one of the lower scoring indicators and therefore needs to be monitored closely. Innovative soil and crop management strategies, including a landscape vision are offered as ideas for achieving sustainable food, feed, fiber, and energy production

    2013-10-01

    Full Text Available The Environmental Impact Assessment (EIA in Colombia constitutes the primary tool for making decisions with respect to projects, works and activities (PWA with potential for significant environmental impacts. In the case of the infrastructure of the PWA, the EIA is mandatory and determines the environmental license (EL for construction and operation. This paper analyzes the methods used to assess the environmental impact of the PWA that have applied for licenses with the Ministry of Environment and Sustainable Development. It was found that the method most frequently used is the qualitative proposal by Conesa, with modifications that reduce the effectiveness of the EIA and favor the subjectivity and bias of the evaluator. Finally a series of recom­mendations to improve the process in the country are proposed.

    Care of the environment is set to be one of the growth industries of the 1990s. Unfortunately, information as to the effect current life styles are having on the environment and, therefore, what remedial action is necessary, varies from the full to the non-existent and, worst of all, from the misleading to the incorrect. For various reasons, some aspects of technology have received greater attention from the media and environmental pressure groups than others. Energy production and conversion technologies, of course, are very much in this category. Indeed, the problem in these areas is not lack of information but a positive surfeit. (author)

    2014-01-01

    Transport infrastructure has a wide array of effects on terrestrial and aquatic ecosystems, and road and railway networks are increasingly being associated with a loss of biodiversity worldwide. Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) are two legal frameworks that concern physical planning, with the potential to identify, predict, mitigate and/or compensate transport infrastructure effects with negative impacts on biodiversity. The aim of this study was to review the treatment of ecological impacts in environmental assessment of transport infrastructure plans and projects. A literature review on the topic of EIA, SEA, biodiversity and transport infrastructure was conducted, and 17 problem categories on the treatment of biodiversity were formulated by means of a content analysis. A review of environmental impact statements and environmental reports (EIS/ER) produced between 2005 and 2013 in Sweden and the UK was then conducted using the list of problems as a checklist. The results show that the treatment of ecological impacts has improved substantially over the years, but that some impacts remain problematic; the treatment of fragmentation, the absence of quantitative analysis and that the impact assessment study area was in general delimited without consideration for the scales of ecological processes. Actions to improve the treatment of ecological impacts could include improved guidelines for spatial and temporal delimitation, and the establishment of a quantitative framework including tools, methods and threshold values. Additionally, capacity building and further method development of EIA and SEA friendly spatial ecological models can aid in clarifying the costs as well as the benefits in development/biodiversity tradeoffs. - Highlights: • The treatment of ecological impacts in EIA and SEA has improved. • Quantitative methods for ecological impact assessment were rarely used • Fragmentation effects were recognized

    1995-01-01

    Executive Order 12898, open-quote Federal Actions to Address Environmental Justice in Minority Populations and Low-Income populations,close-quote directs Federal agencies to make environmental justice part of their mission by involving minorities and low-income populations and by identifying and addressing as appropriate disproportionately high and adverse human health and environmental effects of their programs, policies, and activities on minority and low-income populations. In the Presidential Memorandum transmitting the Executive Order it was stated that environmental justice should be taken into consideration under the National Environmental Policy Act of 1969 (NEPA). NEPA, with its systematic approach and requirements for alternatives analysis and comprehensive public participation, has served as one of the main mechanisms for involving the public in environmental decision-making. This paper addresses challenges faced by the Department of Energy in involving minority and low-income populations in the public involvement activities associated with a national-level environmental impact statement (EIS) and suggests ways to improve agencies' incorporation of environmental justice considerations in NEPA scoping

    Naylor, Rosamond; Matson, Pamela

    Earth's population currently numbers 5.4 billion; even given optimistic assumptions for reduction in growth rates, the number will double by the middle of the next century with most of the increase in the developing countries. Rapid population growth in the developing world raises the fundamental dilemma of how to alleviate chronic hunger and poverty in the short run while preserving the atmosphere and ecosystem services required for long-term human and biospheric sustenance. This dilemma, and the compromises required to solve it, were discussed by twenty-five researchers from five countries at the Aspen Global Change Institute 1992 Summer Science Session III, Food, Conservation, and Global Environmental Change: Is Compromise Possible?, held from August 16 to 28, in Aspen, Colo.

    As the Chinese economy has become an integral part of the global supply chain, quantifying the environmental impacts by Chinese industry is indispensible to understanding the environmental performance of products in general. Comprehensive and consistent environmental data infrastructure, however, is lacking in China, hindering such an understanding. In this paper, we demonstrate a simplified method for assembling and harmonizing various data sources to develop a sectoral environmental database for input-output life cycle assessment (IO-LCA). We first identified key substances by analyzing previous normalization studies and other countries' sectoral environmental databases. Data for priority substances were compiled and then adjusted and validated. The database created from this process was then used to analyze the direct and indirect environmental impacts generated by Chinese rural and urban consumptions. Expenditures on food and other basic household needs like heating and cooking were found to play a dominant role in generating environmental impacts in China, while previous studies of industrialized countries also highlighted the importance of transportation. This database provides background information for LCA through, for example, the hybrid approach, and is also conducive to ongoing efforts to develop generic life cycle inventory databases in China.

  17. Environmental impacts of renewable energy sources

    The global attention has always been focused on the adverse environmental impacts of conventional energy sources. In contrast nonconventional energy sources, particularly the renewable ones, have enjoyed a clean image vis a vis environmental impacts. The only major exception to this general trend has been large hydropower projects; experience has taught that they can be disastrous for the environment. The belief now is that mini hydro and microhydro projects are harmless alternatives. But are renewable energy sources really as benign as is widely believed? The present essay addresses this question in the background of Lovin's classical paradigm which had postulated the hard (malignant) and soft (benign) energy concepts in the first place. It then critically evaluates the environmental impacts of major renewable energy sources. It then comes up with the broad conclusion that renewable energy sources are not the panacea they are popularly perceived to be; indeed in some cases their adverse environmental impacts can be as strongly negative as the impacts of conventional energy sources. The paper also dwells on the steps needed to utilize renewable energy sources without facing environmental backlashes of the type experienced from hydropower projects

    1980-11-30

    Major residuals generated by the conversion process and its auxiliary operations include: (a) coal preparation wastes; (b) gasifier ash; (c) liquefaction solids-char; (d) tail gas or flue gas desulfurization sludge; (e) boiler flyash and bottom ash; (f) raw water treatment sludge, and; (g) biosludges from process wastewater treatment. Recovered sulfur may also require disposal management. Potential environmental and health impacts from each of the residues are described on the basis of characterization of the waste in the perspective of water quality degradation. Coal gasification and liquefaction systems are described in great detail with respect to their associated residuals. Management options are listed with the conclusion that land disposal of the major residual streams is the only viable choice. On-site versus off-site disposal is analyzed with the selection of on-site operations to reduce political, social and institutional pressures, and to optimize the costs of the system. Mechanisms for prevention of leachate generation are described, and various disposal site designs are outlined. It is concluded that co-disposal feasibility of some waste streams must be established in order to make the most preferred solid waste management system feasible. Capacity requirements for the disposal operation were calculated for a 50,000 bbl/day coal liquefaction plant or 250 million SCF/day gasification operation.

  19. A review of municipal solid waste environmental standards with a focus on incinerator residues

    2015-12-01

    Full Text Available Environmental issues are often neglected until a lapse in the care for environment, which leads to serious human health problem, would then put regulation gaps in the spotlight. Environmental regulations and standards are important as they maintain balance among competing resources and help protect human health and the environment. One important environmental standard is related to municipal solid waste (MSW. Proper MSW management is crucial for urban public health. Meanwhile, the sustainability of landfills is also of concern as increasing volumes of MSW consume finite landfill space. The incineration of MSW and the reuse of incinerated residues help alleviate the burden on landfill space. However, the reuse of MSW incinerator residues must be regulated because they may expose the environment to toxic heavy metal elements. The study of environmental standards from different countries applicable to MSW is not widely published, much less those for incinerated MSW residue reuse. This paper compares extant waste classification and reuse standards pertinent to MSW, and explores the unique recent history and policy evolution in some countries exhibiting high environmental regard and rapid changes, so that policy makers can propose new or revise current MSW standards in other countries.

    The use of coal fly ash (CFA), municipal solid waste incinerator bottom ash (MSWIBA) and flue gas desulfurization residue (FGDR) in road construction has become very common owing to its economical advantages. However, these residues may contain toxic constituents that pose an environmental risk if they leach out and flow through the soil, surface water and groundwater. Therefore, it is necessary to assess the ecotoxicity and groundwater impact of these residues before decisions can be made regarding their utilization for road construction. In this study, the physico-chemical characteristics, leaching and phytotoxicity of these residues were investigated. Specifically, multivariate analyses were used to evaluate the contributions of the leaching constituents of the CFA, MSWIBA and FGDR leachates to the germination index of wheat seeds. B, Ba, Cr, Cu, Fe and Pb were found to be more toxic to the wheat seeds than the other heavy metals. Furthermore, the leached concentrations of the constituents from the CFA, MSWIBA and FGDR were below the regulatory threshold limits of the Chinese identification standard for hazardous wastes. Analyses conducted using a numerical groundwater model (WiscLEACH) indicated that the predicted field concentrations of metals from the CFA, MSWIBA and FGDR increased with time up to about 30years at the point of compliance, then decreased with time and distance. Overall, this study demonstrated that the risks resulting from MSWIBA, CFA and FGDR leaching could be assessed before its utilization for road construction, providing crucial information for the adoption of these alternative materials.

    Mansour, Sameeh A

    2008-01-01

    The first use of petroleum-derived pesticides in Egyptian agriculture was initiated in 1950. Early applications consisted of distributing insecticidal dusts containing DDT/BHC/S onto cotton fields. This practice was followed by use of toxaphene until 1961. Carbamates, organophosphates, and synthetic pyrethroids were subsequently used, mainly for applications to cotton. In addition to the use of about 1 million metric tons (t) of pesticides in the agricultural sector over a 50-yr period, specific health and environmental problems are documented in this review. Major problems represented and discussed in this review are human poisoning, incidental toxicity to farm animals, insect pest resistance, destruction of beneficial parasites and predators, contamination of food by pesticide residues, and pollution of environmental ecosystems. Several reports reveal that chlorinated hydrocarbon pesticide residues are still detectable in several environmental compartments; however, these residues are in decline. Since 1990, there is a growing movement toward reduced consumption of traditional pesticides and a tendency to expand use of biopesticides, including "Bt," and plant incorporated protectants (PIPs). On the other hand, DDT and lindane were used for indoor and hygienic purposes as early as 1952. Presently, indoor use of pesticides for pest control is widespread in Egypt. Accurate information concerning the types and amounts of Egyptian household pesticide use, or numbers of poisoning or contamination incidents, is unavailable. Generally, use of indoor pesticides is inadequately managed. The results of a survey of Egyptian farmers' attitudes toward pesticides and their behavior in using them garnered new insights as to how pesticides should be better controlled and regulated in Egypt.

    2005-01-01

    Solar energy systems (photovoltaics, solar thermal, solar power) provide significant environmental benefits in comparison to the conventional energy sources, thus contributing, to the sustainable development of human activities. Sometimes however, their wide scale deployment has to face potential negative environmental implications. These potential problems seem to be a strong barrier for a further dissemination of these systems in some consumers. To cope with these problems this paper presents an overview of an Environmental Impact Assessment. We assess the potential environmental intrusions in order to ameliorate them with new technological innovations and good practices in the future power systems. The analysis provides the potential burdens to the environment, which include - during the construction, the installation and the demolition phases, as well as especially in the case of the central solar technologies - noise and visual intrusion, greenhouse gas emissions, water and soil pollution, energy consumption, labour accidents, impact on archaeological sites or on sensitive ecosystems, negative and positive socio-economic effects

    The environment and the economy are inextricably linked. Today the environmental, economic, and social associated with project and program decisions are at times of such a magnitude and duration that they exceed our ability to understand, let alone mitigate them. Energy production, distribution, pricing, policies, end uses, and externalities demonstrate the need for wise planning and informed decision making. International cooperation, based upon mutually shared respect, responsibility, and innovative solutions is an essential component of addressing contemporary issues, impacts, and opportunities. Both egypt and the united states have laws requiring environmental impact assessments. Just as egypt can learn from our successes and failures in the environmental impact assessment field over the past 36 years, the united states and other nations can learn as egypt develops and innovates its own approaches and solutions

    Forest residue is a major potential feedstock for second-generation biofuel; however, little knowledge exists about the environmental impacts of the development and production of biofuel from such a feedstock. Using a high-resolution regional air quality model, we estimate the air quality impacts of a forest residue based aviation biofuel supply chain scenario in the Pacific Northwestern United States. Using two potential supply chain regions, we find that biomass and biofuel hauling activities will add simulation. Using BenMAP, a health impact assessment tool, we show that avoiding slash pile burning results in a decrease in premature mortality as well as several other nonfatal and minor health effects. In general, we show that most air quality and health benefits result primarily from avoided slash pile burning emissions.

  11. Environmental impact on the polar regions

    International Nuclear Information System (INIS)

    Jaffe, D.A.; Leighton, E.; Tumeo, M.A.

    1994-01-01

    The remote and frigid polar regions are no longer isolated from the activities, pollutants, and controversies that bedevil their more temperate neighbors, say three researchers at the University of Alaska in Fairbanks. For example, Daniel A. Jaffe, Elizabeth Leighton, and Mark A. Tumeo point to traces of DDT, PCBs, and heavy metals that routinely turn up in arctic marine mammals and to the ozone hole over the Antarctic. While similar in environmental makeup, the arctic and Antarctic are poles apart in their political structure and, thus, in their environmental exposure, the researchers note. The Antarctic is managed under a long-standing international treaty, while the arctic is sovereign territory to eight separate nations. The international treaty sets aside the Antarctic for peaceful scientific research within strict environmental boundaries. It bans both military activity and minerals extraction-the two activities that have caused the most damage in the arctic. The main threats to Antarctica's environment come from the intrusion of major scientific research operations and the growing tourism industry. On the other hand, the arctic suffered from the massive Cold War military buildup by both the United States and the former Soviet Union. The environmental residue from that buildup is only now being revealed, the authors say. Major oil and gas drilling and coal and metal-ore mining also have taken a huge environmental toll, they add

  12. Environmental impact assessment of nuclear desalination

    International Nuclear Information System (INIS)

    2010-03-01

    Nuclear desalination is gaining interest among the IAEA Member States, as indicated by the planned projects, and it is expected that the number of nuclear desalination plants will increase in the near future. The IAEA has already provided its Member States with reports and documents that disseminate information regarding the technical and economic feasibility of nuclear desalination. With the rising environmental awareness, in the scope of IAEA's activities on seawater desalination using nuclear power, a need was identified for a report that would provide a generic assessment of the environmental issues in nuclear desalination. In order to offer an overview of specific environmental impacts which are to be expected, their probable magnitude, and recommended mitigation measures, this publication encompasses information provided by the IAEA Member States as well as other specialized sources. It is intended for decision makers and experts dealing with environmental, desalination and water management issues, offering insight into the environmental aspects that are essential in planning and developing nuclear desalination

    Dory, A.B.

    1981-08-01

    The author introduces the subject with an overview of the regulatory requirments and philosophy applied to uranium mines and mills. The special attention given to tailings management is highlighted, and a discussion of the basic environmental concerns is concluded with an itemizing of the main tasks facing the AECB. The extent of the environmental impact of uranium mining, milling and waste management is illustrated with specific details pertaining to mines in the Elliot Lake area. The author concludes that the impact on the ground and surface water system is not alarming, and the impact on air quality is not significant beyond a few hundred metres from the mining facilities. The publicly perceived impact is discussed, followed by a rationale for the continued licensing of new uranium mining operations complete with tailings management facilities

  2. Risk and environmental impact assessment: nuclear and environmental licensing interface

    International Nuclear Information System (INIS)

    Costa, Eduardo M.; Monteiro, Iara A.

    1997-01-01

    The main aims of this paper are the identification and discussion of interfaces and application of common concepts in the existing nuclear and environmental licensing procedures. Risk and impact assessment of nuclear electricity generation are two of these concepts which are discussed detail. The risk concept, which had initially focused on engineering projects, has been extended to many other areas of human activity. Risk resulting from the use of ionization radiation has been associated to the dose for the critical members of the public. Therefore, radiation protection applies basic dose limits which are established in national and international recommendations. These recommendations are increasing the emphasis to keep all the exposures to ionizing radiation as low as reasonable achievable, economical and social factors being taken into account. On the other hand, environmental impact assessment has been used as a tool in planning and decision-making processes, thus including environmental concern in the discussion of social and economical development strategies. This paper aims to discuss the association of these two concepts by presenting the procedures of control of radiological impact during normal operation of a nuclear power plant and the various forms of risk communication to the public in the case of events occurrence.

    Loevblad, Gun; Skaerby, Lena

    2000-06-01

    The report is the final report from a jointly financed project within lVL studying methodology for environmental impact assessments (EIAs). The aim has been to show possibilities and problems with EIAs for air pollution emissions from energy production plants in environments where critical loads and levels are exceeded. The project has mainly dealt with plants emitting air pollutants with environmental effects on the regional scale, including sulphur and nitrogen compounds, volatile organic compounds and particles, and effects such as acidification, eutrophication and ozone formation. Conclusions from the work are that project managers, environmental auditors, together with regional and local authorities could have use for better and more detailed guidelines, in the form of more detailed emission data from different types of alternative plants; Guidelines for the elaborating and assessing of relevant zero alternatives; Regional environmental goals and guidelines for the acceptable contribution to these by different activities; Criteria for the definition of the areas of 'environmental influence'. Furthermore, quantitative relationships between exposure and effects may contribute to better and more detailed descriptions of environmental impact and the need of decreasing the load for the recovery of polluted ecosystems

    Energy Technology Data Exchange (ETDEWEB)

    Kolokotroni, M.; Robinson-Gayle, S.; Tanno, S.; Cripps, A.

    2004-02-01

    The design of a building facade influences internal thermal and lighting conditions and use associated with the provision of these conditions. Key decisions about the building are usually taken during the concept design stage of a building, while decisions about method of providing the environmental conditions are often made later in the design. This dilemma is addressed by the development of a concept design tool that allows the team to investigate the effect of facade design on the resulting internal environmental conditions, energy use and environmental impact. The concept design tool was developed performing detailed thermal, lighting and environmental modelling for a number of office building facade designs and a range of parameters that affect directly the environmental performance of an office building. The results are presented in a user-friendly interface as a minimum number of inputs. Key parameter outputs (such as temperature, lighting, heating/cooling energy demand, embodied energy and eco-points) can then be viewed, more detailed analysis can also be created for specified facade designs. A parametric analysis of the summary result outputs for selected facade parameters indicates that natural ventilation and cooling can reduce the environmental impact of offices by up to 16%, although the energy demand could increase significantly. Improving the construction standard and reducing the internal heat loads can reduce the environmental impact by up to 2 this tool at early design stages will benefit the design team through an improved understanding of the dynamics between facade design and building services and assist with a more integrated approach.

  17. Benchmarking performance: Environmental impact statements in Egypt

    International Nuclear Information System (INIS)

    Badr, El-Sayed A.; Zahran, Ashraf A.; Cashmore, Matthew

    2011-01-01

    Environmental impact assessment (EIA) was formally introduced in Egypt in 1994. This short paper evaluates 'how well' the EIA process is working in practice in Egypt, by reviewing the quality of 45 environmental impact statements (EISs) produced between 2000 and 2007 for a variety of project types. The Lee and Colley review package was used to assess the quality of the selected EISs. About 69% of the EISs sampled were found to be of a satisfactory quality. An assessment of the performance of different elements of the EIA process indicates that descriptive tasks tend to be performed better than scientific tasks. The quality of core elements of EIA (e.g., impact prediction, significance evaluation, scoping and consideration of alternatives) appears to be particularly problematic. Variables that influence the quality of EISs are identified and a number of broad recommendations are made for improving the effectiveness of the EIA system.

  18. Environmental impact statement requirements for CNEA

    International Nuclear Information System (INIS)

    Ciurciolo, Melisa N.; Mender, J. A.

    2009-01-01

    The purpose of this paper is to describe the legal framework on Environmental Impact Assessment (EIA) regarding the activities of the National Atomic Energy Commission (Comision Nacional de Energia Atomica, CNEA), and particularly, the Procedure for Internal Management of Environmental Impact Statements of CNEA (PN-PR-027). According to the distribution of powers stated in article 41 of the National Constitution, the environmental legal framework is constituted by National minimum standards for environmental protection and complementary provincial and municipal regulations. As a result, the EIA legal framework is not uniform across the Nation, and therefore, it differs according to the jurisdiction in which the activity subject to EIA is developed. Notwithstanding, the General Statute of the Environment (25.675) requires EIA for any project or activity developed in the National territory, which may cause a significant degradation to the environment, any of its components, or affect the populations' quality of life in a significant way. Since CNEA develops activities along the National territory, it is not possible to determine a uniform legal EIA framework for the entire Institution. Consequently, the binding requirements for Environmental Impact Statements (EISs) of CNEA activities differ among the activities developed in the different locations and atomic centers. In order to achieve a uniform environmental performance in CNEA, it has been considered necessary to uniform, in the internal sphere, the binding requirements for EIS, by means of a procedure written within the framework of the Environmental Management System of the Institution. The purpose of the Procedure for Internal Management of Environmental Impact Statements is to determine the requirements to be complied by the atomic centers, locations and enterprises associated with CNEA, regarding EIS Management. This Procedure shall apply to those projects and activities subjected to EIA, according to a

  19. Environmental consequences of deltamethrin residues in cattle feces in an African agricultural landscape.

    2018-03-01

    Pyrethroid insecticides are widely used to control ectoparasites of livestock, particularly ticks and biting flies. Their use in African livestock systems is increasing, driven by the need to increase productivity and local food security. However, insecticide residues present in the dung after treatment are toxic to dung-inhabiting insects. In a semiarid agricultural habitat in Botswana, dung beetle adult mortality, brood ball production, and larval survival were compared between untreated cattle dung and cattle dung spiked with deltamethrin, to give concentrations of 0.01, 0.1, 0.5, or 1 ppm. Cattle dung-baited pitfall traps were used to measure repellent effects of deltamethrin in dung on Scarabaeidae. Dung decomposition rate was also examined. There was significantly increased mortality of adult dung beetles colonizing pats that contained deltamethrin compared to insecticide-free pats. Brood ball production was significantly reduced at concentrations of 1 ppm; larval survival was significantly reduced in dung containing 0.1 ppm deltamethrin and above. There was no difference in the number of Scarabaeidae attracted to dung containing any of the deltamethrin concentrations. Dung decomposition was significantly reduced even at the lowest concentration (0.01 ppm) compared to insecticide-free dung. The widespread use of deltamethrin in African agricultural ecosystems is a significant cause for concern; sustained use is likely to damage dung beetle populations and their provision of environmentally and economically important ecosystem services. Contaminated dung buried by paracoprid (tunneling) beetles may retain insecticidal effects, with impacts on developing larvae below ground. Lethal and sublethal effects on entire dung beetle (Scarabaeidae) communities could impair ecosystem function in agricultural landscapes.

  20. Honeymoon uranium project: final environmental impact statement

    International Nuclear Information System (INIS)

    1981-03-01

    The Honeymoon joint venturers propose to develop a uranium deposit in the Lake Frome basin of South Australia. This will involve construction of a well field and treatment plant to mine and extract the uranium by solution mining techniques. The proposed mine is located on featureless saltbush plains where sheep grazing is the present land use. Residual impacts on the environment will be minor. Minimal radioactivity will remain near the surface. Mineralisation will be mobilised by the solutions injected into the basal sand aquifer and the acidity and radium content of the ground water will be increased. This water is already useless as a resource. Short term impacts will also be minor. Submissions received were mostly concerned with ground water and to a lesser extent, radiological aspects

  1. Environmental impact estimation of mold making process

    Science.gov (United States)

    Kong, Daeyoung

    Increasing concern of environmental sustainability regarding depletion of natural resources and resulting negative environmental impact has triggered various movements to address these issues. Various regulations about product life cycle have been made and applied to industries. As a result, how to evaluate the environmental impact and how to improve current technologies has become an important issue to product developers. Molds and dies are very generally used manufacturing tools and indispensible parts to the production of many products. However, evaluating environmental impact in mold and die manufacturing is not well understood and not much accepted yet. The objective of this thesis is to provide an effective and straightforward way of environmental analysis for mold and die manufacturing practice. For this, current limitations of existing tools were identified. While conventional life cycle assessment tools provide a lot of life cycle inventories, reliable data is not sufficient for the mold and die manufacturer. Even with comprehensive data input, current LCA tools only provide another comprehensive result which is not directly applicable to problem solving. These issues are critical especially to the mold and die manufacturer with limited resource and time. This thesis addresses the issues based on understanding the needs of mold and die manufacturers. Computer aided manufacturing (CAM) is the most frequently used software tool and includes most manufacturing information including the process definition and sometimes geometric modeling. Another important usage of CAM software tools is problem identification by process simulation. Under the virtual environment, possible problems are detected and solved. Environmental impact can be handled in the same manner. To manufacture molds and dies with minimizing the associated environmental impact, possible environmental impact sources must be minimized before the execution in the virtual environment. Molds and dies

    BPA's preferred alternative is the Emphasize Conservation Alternative. System and environmental costs are low. Environmental impacts from conservation are minimal. This alternative is cost-effective and environmentally responsible; only the High Conservation Alternative has lower costs and fewer environmental impacts. However, there is some concern about the cost-effectiveness, reliability, and commercial availability of the high conservation resources. If the supply of the additional conservation potential was confirmed and it became cost-effective, the High Conservation Alternative would be preferred. The Draft Resource Programs EIS was released for public review during the summer of 1992. Comments received by letter or in the public hearing held June 16, 1992, were used to revise and update data and analyses of the EIS (public comments and BPA's responses are contained in Volume III of the Final EIS). In addition, a number of revisions were made in the Chapter 3 material describing each resource type, and in Chapter 4 and the Summary, to assure consistency with the modeling and analysis in Chapter 5. Additional information about the capacity aspects of each resource type and alternative has been added, and the material on conservation and its impacts has been reorganized

    1993-02-01

    Every two years, BA prepares a Resource Program, which identifies the resource actions BA will take to meet its obligation to serve the forecasted power requirements of its customers. The Resource Programs Environmental Impact Statement (RPEIS) is a programmatic environmental document that will support decisions made in several future Resource Programs. Environmental documents tiered to this EIS may be prepared on a site-specific basis. The RPEIS includes a description of the environmental effects and mitigation for the various resource types available in order to evaluate the trade-offs among them. It also assesses the environmental impacts of adding thirteen alternative combinations of resources to the existing power system. The alternatives represent the range of actions BA could take to meet its load obligations. Each of the alternatives allows BA to meet the almost 5,000 average megawatt load increase that could occur with high load growth, or an equivalent need for resources caused by a combination of load growth and any future loss of resources

    Science.gov (United States)

    The market growth of consumer electronics makes it essential for industries and policy-makers to work together to develop sustainable products. The objective of this study is to better understand how to promote environmentally sustainable consumer electronics by examining the use of various materials in laptop enclosures (excluding mounting hardware, internal components, and insulation) using screening-level life cycle assessment. The baseline material, is a fossil plastic blend of polycarbonate-acrylonitrile butadiene styrene. Alternative materials include polylactic acid, bamboo, aluminum, and various combinations of these materials known to be currently used or being considered for use in laptops. The flame retardants considered in this study are bisphenol A bis(diphenyl phosphate), triphenyl phosphate, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, and borax-boric acid-phosphorous acid. The Tool for the Reduction and Assessment of Chemical and other environmental Impacts v2.1 was used for the assessment of impacts related to climate change, human and ecological health, and resource use. The assessment demonstrates that plastics, relative to the other materials, are currently some of the better performing materials in terms of having the lowest potential environmental impact for a greater number of impact categories based on product life cycle models developed in this study. For fossil plastics, the material performance increases with increasing post-con

    The tissue residue dose concept has been used, although in a limited manner, in environmental toxicology for more than 100 y. This review outlines the history of this approach and the technical background for organic chemicals and metals. Although the toxicity of both can be explained in tissue residue terms, the relationship between external exposure concentration, body and/or tissues dose surrogates, and the effective internal dose at the sites of toxic action tends to be more complex for metals. Various issues and current limitations related to research and regulatory applications are also examined. It is clear that the tissue residue approach (TRA) should be an integral component in future efforts to enhance the generation, understanding, and utility of toxicity testing data, both in the laboratory and in the field. To accomplish these goals, several key areas need to be addressed: 1) development of a risk-based interpretive framework linking toxicology and ecology at multiple levels of biological organization and incorporating organism-based dose metrics; 2) a broadly applicable, generally accepted classification scheme for modes/mechanisms of toxic action with explicit consideration of residue information to improve both single chemical and mixture toxicity data interpretation and regulatory risk assessment; 3) toxicity testing protocols updated to ensure collection of adequate residue information, along with toxicokinetics and toxicodynamics information, based on explicitly defined toxicological models accompanied by toxicological model validation; 4) continued development of residueeffect databases is needed ensure their ongoing utility; and 5) regulatory guidance incorporating residue-based testing and interpretation approaches, essential in various jurisdictions. ??:2010 SETAC.

    Dietary choices drive both health and environmental outcomes. Information on diets come from many sources, with nationally recommended diets (NRDs) by governmental or similar advisory bodies the most authoritative. Little or no attention is placed on the environmental impacts within NRDs. Here we quantify the impact of nation-specific NRDs, compared with an average diet in 37 nations, representing 64% of global population. We focus on greenhouse gases (GHGs), eutrophication, and land use because these have impacts reaching or exceeding planetary boundaries. We show that compared with average diets, NRDs in high-income nations are associated with reductions in GHG, eutrophication, and land use from 13.0 to 24.8%, 9.8 to 21.3%, and 5.7 to 17.6%, respectively. In upper-middle–income nations, NRDs are associated with slight decrease in impacts of 0.8–12.2%, 7.7–19.4%, and 7.2–18.6%. In poorer middle-income nations, impacts increase by 12.4–17.0%, 24.5–31.9%, and 8.8–14.8%. The reduced environmental impact in high-income countries is driven by reductions in calories (∼54% of effect) and a change in composition (∼46%). The increased environmental impacts of NRDs in low- and middle-income nations are associated with increased intake in animal products. Uniform adoption of NRDs across these nations would result in reductions of 0.19–0.53 Gt CO2 eq⋅a−1, 4.32–10.6 Gt PO43− eq⋅a−1, and 1.5–2.8 million km2, while providing the health cobenefits of adopting an NRD. As a small number of dietary guidelines are beginning to incorporate more general environmental concerns, we anticipate that this work will provide a standardized baseline for future work to optimize recommended diets further.

    Climate change results in the increase or decrease in temperature and rainfall. These have significant impact on environment - impinge agricultural crop yields, affect human health, cause changes to forests and other ecosystems, and even impact our energy supply. Climate change is a global phenomenon and its impact can be observed on Pakistan's economy and environment. This paper contains details concerning the climate change and environmental impacts. It takes into account current and projected key vulnerabilities, prospects for adaptation, and the relationships between climate change mitigation and environment. The purpose of the study is to devise national policies and incentive systems combined with national level capacity-building programs to encourage demand-oriented conservation technologies. Recommendations are also made to abate the climate change related issues in country. (author)

  2. Outline of environmental impact of waste management

    International Nuclear Information System (INIS)

    1979-09-01

    This document presents background information on the environmental impacts from the management and disposal of radioactive waste for seven reference fuel cycles selected by INFCE Working Group 7, but excluding the health and safety impact on man. The main factors considered were: use of natural resources, land, water, energy, labour and materials; effects of chemical and thermal effluents; effects of meteorology, hydrology and natural hazards; and social effects. The environmental impacts are generally largest for the once-through fuel cycles and smallest for the FBR and HWR U/Th cycles, due to the impacts being correlated to uranium requirements. The main impact is the use of land which varies from 0.1 - 1.6 ha/GWa with the FBR strategy requiring the smallest use of land and the LWR once-through strategy the largest. The land use for mill tailings is, except for the FBR and U/Th cycles, dominant compared to the land use for the rest of the fuel cycle

  3. Environmental impacts associated with Project Rio Blanco

    International Nuclear Information System (INIS)

    Alldredge, A.W.; Whicker, F.W.; Hanson, W.C.

    Project Rio Blanco, an experiment involving deep underground detonation of three 30-kton nuclear explosives designed to stimulate natural gas flow in geologic formations of low permeability, was conducted in western Colorado on 17 May 1973. Environmental impacts associated with this experiment were divided into three categories: radiation, ground motion, and conventional physical activities. Radiation and ground motion are unique to this type experiment while conventional activities would be associated with any type of resource development. The objective of observations made at Rio Blanco was to qualitatively and, where possible, quantitatively ascertain environmental impacts associated with the project. Observations indicated that ground motion and conventional activities appeared to cause the greatest impacts. Ground motion impacts were most severe within 2.4 km of the emplacement well (EW) and were predominantly associated with steep ravine and stream banks and rocky cliffs. Following the detonation, flow and turbidity had increased in a small stream adjacent to the EW. Animals receiving deleterious impacts were those associated with stream banks, cliffs and burrows. No mortality or injury was observed in any large animals. (U.S.)

  4. Manual: environmental impact statement and intervention regulation

    Neumann, K.

    1992-01-01

    In order to be able to fulfil also legally the important tasks of environmental protection and natural preservation in the last ten years numerous legal provisions have been issued. Many of these laws require that the environmental impact of projects and constructional measures is taken into account to a higher degree. Two important instruments in this connection are the impact statement and the intervention regulation of natural preservation. Their importance and consequences for the planning and realization of projects are until now not sufficiently know. This manual is to fill this gap. This booklet shall help builder-owners and investors to realize their building projects in a way which is compatible with the environment. For architects and planners information is given in this manual about the requirements to be fulfilled in the individual planning and licensing procedures. The booklet is structured in a way that builder-owners, consultants and authorities find quickly the information needed. (orig./KW) [de

    Insect residues can cause premature transition to turbulent flow on laminar flow airfoils. Engineered surfaces that mitigate the adhesion of insect residues provide, therefore, a route to more efficient aerodynamics and reduced fuel burn rates. Areal coverage and heights of residues depend not only on surface properties, but also on impact conditions. We report high speed photography of fruit fly impacts at different angles of inclination on a rigid aluminum surface, optical microscopy and profilometry, and contact angle goniometry to support the design of engineered surfaces. For the polyurethane and epoxy coatings studied, some of which exhibited superhydrophobicity, it was determined that impact angle and surface compositions play critical roles in the efficacy of these surfaces to reduce insect residue adhesion.

  6. Low environmental impact technologies for road construction

    2013-10-01

    Full Text Available The “sustainability” concept relates to the prolonging of human economic systems with as little detrimental impact on ecological systems as possible. Construction that exhibits good environmental stewardship and practices that conserve resources in a manner that allow growth and development to be sustained for the long-term without degrading the environment are indispensable in a developed society.Past, current and future advancements in road construction as an environmentally sustainable paving material are especially important because the quantities of asphalt used annually in Europe as well as in the U.S. and all over the world are large. This research project is aimed to demonstrate the dual value of some new technologies in regards to the environmental and mechanical performance and to suggest a low environmental impact design procedure. In fact, the use of eco-friendly materials is the first phase towards an eco-compatible design but it cannot be the only step. The eco-compatible approach should be extended also to the design method and material characterization because only with these phases is it possible to exploit the maximum potential properties of the used materials.

  7. Environmental Impact Assessment and Space Activities

    Science.gov (United States)

    Viikari, L.

    Environmental Impact Assessment (EIA) is a common tool for environment a l protection and management on Earth today, as prior assessment of the environmental consequences of planned activities. It is meant to provide the decision-makers with as comprehensive as possible information about the different environmental effects the proposed activity would entail, including alternative courses of action and the zero-alternative (i.e. the no action alternative). Additionally, plans for mitigation in respect of each alternative are to be outlined. The assessments take account of i.a. environmental impacts on ecosystems, diminution of aesthetic and scientific values, long-term or cumulative effects, as well as transfrontier implications. They also consider issues such as pollution control, environmental protection measures, reporting, post-project analysis, rehabilitation and so on. Also uncertainties in the assessment process are to be expressly presented. Most importantly, a common requirement also is that the results of the impact studies are presented in a way comprehensible to the g neral public,e too. Although the central aspect of the EIA is to provide the decision-makers with scientific information, the process also has other important implications. One of the most relevant of them is the involvement of those people potentially affected in some way by the proposed activity: most EIA systems require in some way the participation of the public, alongside with the relevant governmental authorities and other stake-holders. Such public involvement has various aims and goals: it may serve as a testimony to good governance in general, or be considered in more practical terms as improved planning, due to the concrete contribution of the public to the decision-making process. Obviously, it also is a tool for reducing conflict and developing wider support for the eventual decisions. In short, it enables the public to gain information about planned activities and influence

  8. Hydroelectric power and global environmental problems: benefits and environmental impacts

    International Nuclear Information System (INIS)

    Chabot, B.

    1992-01-01

    The risk of global warming is one of the most serious global environmental problems. It is due to the increase of greenhouse gases emissions, mainly because of the use of fossil fuels in the energy sector, particularly for electricity generation. At an international level, experts now agree that measures are to be taken to reduce this risk. In the energy sector, an improvement of energy efficiency and an increase of nuclear electricity generation are often presented as the best available solutions. Renewable energy sources are often presented as a solution with a negligible potential impact, and sometimes, hydro power is even forgotten, or its coasts and its potential impacts on local environment are presented as an obstacle to its positive contribution to the reduction of global warming risk. Without denying the positive impacts of other solutions, this paper explains the possibilities and the benefits of an increased use of hydroelectric power, when implemented with a minimum impact on local environment and with a synergistic effect with the rational use of generated energy, in order to have access to a sustainable development. 19 refs., 6 figs

    The goal of this study was to identify drivers of environmental impact and quantify their influence on the environmental performance of wooden and massive residential and office buildings. We performed a life cycle assessment and used thermal simulation to quantify operational energy demand and to account for differences in thermal inertia of building mass. Twenty-eight input parameters, affecting operation, design, material, and exogenic building properties were sampled in a Monte Carlo analysis. To determine sensitivity, we calculated the correlation between each parameter and the resulting life cycle inventory and impact assessment scores. Parameters affecting operational energy demand and energy conversion are the most influential for the building's total environmental performance. For climate change, electricity mix, ventilation rate, heating system, and construction material rank the highest. Thermal inertia results in an average 2-6% difference in heat demand. Nonrenewable cumulative energy demand of wooden buildings is 18% lower, compared to a massive variant. Total cumulative energy demand is comparable. The median climate change impact is 25% lower, including end-of-life material credits and 22% lower, when credits are excluded. The findings are valid for small offices and residential buildings in Switzerland and regions with similar building culture, construction material production, and climate.

  10. Environmental impact of power generation: a review

    International Nuclear Information System (INIS)

    Lima-e-Silva, Pedro Paulo de

    1996-01-01

    The increasing worldwide concern about the planet health is reflected in the willing-to-pay behavior in face of environmentally sound products (the case of American unleaded gasoline) and also in the recently approved international standards as ISO-14000. Considering this, a comparison between major energy sources, like Hydro, Thermal and Nuclear electricity, strictly in terms of environmental impact, becomes relevant. this paper intends to trace a critical analysis of the actual environmental impact occurred in the last 20 years, comparing it with the imagined impact that was foreseen 20 years ago, and making some comments about the future. What one sees nowadays is quite a different situation as it was seen by the environmentalists in Brazil at that time (1976). The cost of land around rivers has increased significantly; social problem with flooding land is even critical in several areas; forests are given higher value than ever; the CO 2 yield has become a world concern, as SOx and NOx as well; C H4 released from flooded forests is a powerful greenhouse gas; the safety of Nuclear Power Plants are still questioned, as well whether or not the uranium reserves are going to support an increasing demand for more 20 years; new standards in public acceptance of pollution has been established. A greater dose of rationale should be put into this discussion. (author)

    Although China owns large coal reserves, it now faces the problem of depletion of its coal resources in advance. The coal-based energy mix in China will not change in the short term, and a means of delaying the coal resources depletion is therefore urgently required. The residual coal was exploited first with a lower recovery percentage and was evaluated as commercially valuable damaged coal. This approach is in comparison to past evaluations when the residual coal was allocated as exploitation losses. Coal recovery rates, the calculation method of residual coal reserves and statistics of its mines in China were given. On this basis, a discussion concerning the impacts on the delay of China's coal depletion, development of coal exploitation and sustainable developments, as well as technologies and relevant policies, were presented. It is considered that the exploitation of residual coal can effectively delay China's coal depletion, inhibit the construction of new mines, redress the imbalance between supply and demand of coal in eastern China, improve the mining area environment and guarantee social stability. The Chinese government supports the exploitation technologies of residual coal. Hence, exploiting residual coal is of considerable importance in sustainable development of the coal industry in China. - Highlights: •Pay attention to residual coal under changing energy-mix environment in China. •Estimate residual coal reserves and investigate its exploitation mines. •Discuss impacts of residual coal exploitation on delay of coal depletion in China. •Discuss impacts on coal mining industry and residual coal exploitation technology. •Give corresponding policy prescriptions.

  14. An adjoint method of sensitivity analysis for residual vibrations of structures subject to impacts

    Science.gov (United States)

    Yan, Kun; Cheng, Gengdong

    2018-03-01

    For structures subject to impact loads, the residual vibration reduction is more and more important as the machines become faster and lighter. An efficient sensitivity analysis of residual vibration with respect to structural or operational parameters is indispensable for using a gradient based optimization algorithm, which reduces the residual vibration in either active or passive way. In this paper, an integrated quadratic performance index is used as the measure of the residual vibration, since it globally measures the residual vibration response and its calculation can be simplified greatly with Lyapunov equation. Several sensitivity analysis approaches for performance index were developed based on the assumption that the initial excitations of residual vibration were given and independent of structural design. Since the resulting excitations by the impact load often depend on structural design, this paper aims to propose a new efficient sensitivity analysis method for residual vibration of structures subject to impacts to consider the dependence. The new method is developed by combining two existing methods and using adjoint variable approach. Three numerical examples are carried out and demonstrate the accuracy of the proposed method. The numerical results show that the dependence of initial excitations on structural design variables may strongly affects the accuracy of sensitivities.

  15. Determining Vulnerability Importance in Environmental Impact Assessment

    International Nuclear Information System (INIS)

    Toro, Javier; Duarte, Oscar; Requena, Ignacio; Zamorano, Montserrat

    2012-01-01

    The concept of vulnerability has been used to describe the susceptibility of physical, biotic, and social systems to harm or hazard. In this sense, it is a tool that reduces the uncertainties of Environmental Impact Assessment (EIA) since it does not depend exclusively on the value assessments of the evaluator, but rather is based on the environmental state indicators of the site where the projects or activities are being carried out. The concept of vulnerability thus reduces the possibility that evaluators will subjectively interpret results, and be influenced by outside interests and pressures during projects. However, up until now, EIA has been hindered by a lack of effective methods. This research study analyzes the concept of vulnerability, defines Vulnerability Importance and proposes its inclusion in qualitative EIA methodology. The method used to quantify Vulnerability Importance is based on a set of environmental factors and indicators that provide a comprehensive overview of the environmental state. The results obtained in Colombia highlight the usefulness and objectivity of this method since there is a direct relation between this value and the environmental state of the departments analyzed. - Research Highlights: ► The concept of vulnerability could be considered defining Vulnerability Importance included in qualitative EIA methodology. ► The use of the concept of environmental vulnerability could reduce the subjectivity of qualitative methods of EIA. ► A method to quantify the Vulnerability Importance proposed provides a comprehensive overview of the environmental state. ► Results in Colombia highlight the usefulness and objectivity of this method.

    This paper presents a number of techniques that can be used to assess environmental impacts on a regional scale. Regional methodologies have been developed which examine impacts upon aquatic and terrestrial biota in regions through consideration of changes in land use, land cover, air quality, water resource use, and water quality. Techniques used to assess long-range atmospheric transport, water resources, effects on sensitive forest and animal species, and impacts on man are presented in this paper, along with an optimization approach which serves to integrate the analytical techniques in an overall assessment framework. A brief review of the research approach and certain modeling techniques used within one regional studies program is provided. While it is not an all inclusive report on regional analyses, it does present an illustration of the types of analyses that can be performed on a regional scale

    Assessment of underwater noise is increasingly required by regulators of development projects in marine and freshwater habitats, and noise pollution can be a constraining factor in the consenting process. Noise levels arising from the proposed activity are modelled and the potential impact on species of interest within the affected area is then evaluated. Although there is considerable uncertainty in the relationship between noise levels and impacts on aquatic species, the science underlying noise modelling is well understood. Nevertheless, many environmental impact assessments (EIAs) do not reflect best practice, and stakeholders and decision makers in the EIA process are often unfamiliar with the concepts and terminology that are integral to interpreting noise exposure predictions. In this paper, we review the process of underwater noise modelling and explore the factors affecting predictions of noise exposure. Finally, we illustrate the consequences of errors and uncertainties in noise modelling, and discuss future research needs to reduce uncertainty in noise assessments.

    Forest residues are an important source of biomass. Among these, Coffee Cut-Stems (CCS) are an abundant wood waste in Colombia obtained from coffee crops renovation. However, only low quantities of these residues are used directly in combustion processes for heating and cooking in coffee farms where their energy efficiency is very low. In the present work, an energy and environmental assessment of two bioenergy production processes (ethanol fermentation and gasification) using CCS as raw material was performed. Biomass gasification seems to be the most promising thermochemical method for bioenergy production whereas, ethanol fermentation is a widely studied biochemical method to produce biofuels. Experimental runs of the CCS gasification were carried out and the synthesis gas composition was monitored. Prior to the fermentation process, a treatment of the CCS is required from which sugar content was determined and then, in the fermentation process, the ethanol yield was calculated. Both processes were simulated in order to obtain the mass and energy balance that are used to assess the energy efficiency and the potential environmental impact (PEI). Moderate high energy efficiency and low environmental impacts were obtained from the CCS gasification. In contrast, high environmental impacts in different categories and low energy efficiencies were calculated from the ethanolic fermentation. Biomass gasification seems to be the most promising technology for the use of Coffee Cut-Stems with high energy yields and low environmental issues. Copyright © 2017 Elsevier Ltd.

    2012-01-01

    Full Text Available Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.

    Rapid growth of the volume of waste from PV cells is expected in the following years. The problem of its utilization seems to be the most important issue for future waste management systems. The environmental impacts of the PV recycling scenario are presented in the manuscript. The analysis is based on the LCA approach and the average data available in specialized databases for silicon standard PV cell is used. The functional unit includes parameters like: efficiency, composition, surface area. The discussion on the environmental impact change due to the location of the PV production and waste processing plants is presented in the manuscript. Additionally, the discussion on the environmental effect of substituting different energy resources with PV cells is presented in the manuscript. The analysis of the PV cell life cycle scenario presented in the article was performed using the SIMA PRO software and data from Ecoinvent 3.0 database together with additional data obtained from other sources.

  10. Influence of agricultural residues interpretation and allocation procedures on the environmental performance of bioelectricity production – A case study on woodchips from apple orchards

    International Nuclear Information System (INIS)

    2015-01-01

    Highlights: • An LCA of bioelectricity production from apple woody residues (AWRs) is performed. • Two AWRs interpretation are investigated: by-products and co-products. • Different allocation procedures are used for upstream and downstream emissions. • AWRs guarantee significant environmental benefits, when interpreted as by-products. - Abstract: Agricultural woody residues are available in massive quantities and provide a considerable potential for energy production. However, to encourage environmentally sustainable bioenergy strategies, it is necessary to assess the environmental performance of each specific bioenergy chain. Life cycle assessment (LCA) is recognized to be one of the best methodologies to evaluate the environmental burdens of bioenergy chains. The application of LCA to bioenergy from agricultural residues requires practitioners to make choices on how to interpret agricultural residues (i.e. by-products or co-products) and on how to allocate emissions among the different products generated along the bioenergy chain. These are among the most debated issues in the LCA community, given their potentially large influence on final LCA outcomes. A uniform consensus on these issues is still lacking, and no single method is equally suitable for all solutions. The aim of this paper is to assess how different ways of agricultural residue interpretation and different allocation methods (both of upstream and downstream emissions), affect the environmental performance of bioenergy production fed by agricultural residues. In order to address the issue, we perform a full attributional LCA of the electricity production in a combustion combined heat and power plant (CHP) fed with woody residues from apple orchards (AWRs), as a case study. Bioelectricity production from CHP fed with agricultural residues is a good example of a multifunctional process, since multiple products (e.g. grain, fruit, straw, wood, etc.) and energy (e.g. heat and power) are co

  2. Cogeneration plant noise: Environmental impacts and abatement

    International Nuclear Information System (INIS)

    De Renzio, M.; Ciocca, B.

    1991-01-01

    In Italy, ever increasing attention to environmental problems has led to legislation requiring cogeneration plant owners to perform environmental impact assessments in order to determine plant conformity with pollution laws. This paper, based on an in-depth analysis of physics fundamentals relevant to the nature and effects of noise, examines the principal sources of noise in industrial cogeneration plants and the intensity and range of the effects of this noise on the local environment. A review is then made of the different methods of noise pollution abatement (e.g., heat and corrosion resistant silencers for gas turbines, varying types and thicknesses of acoustic insulation placed in specific locations) that can be effectively applied to cogeneration plant equipment and housing

  3. Citizens' actions and environmental impact statements

    International Nuclear Information System (INIS)

    Waelde, T.

    1975-01-01

    Above all, two kinds of citizens' participation in environmental decisions are to be considered: on the one hand the suit for damages and compensation for the purpose of internalization of external effects, and on the other hand the actions with the aim to influence character and content of public final decision cases. This is where cooperation and contributions towards state activities with more concern for the environment come into it. This sphere is investigated. Combined are the possibility of judicially arranged citizens' participation and a modern instrument of public decision: environmental impact statements. At the moment these appear to become exclusively an instrument for internal administration management. However, it is possible - this can be confirmed in comparative law - to couple this for the purpose of administration created instrument of technology assessment with citizens' actions. Therefore, the article aims to point to a solution how modern administration management through judicial mediation can orientate itself according to citizens' interests. (orig./LN) [de

  4. Impact of Residual Fragments following Endourological Treatments in Renal Stones

    2012-01-01

    Full Text Available Today, shock wave lithotripsy (SWL, percutaneous nephrolithotomy (PCNL, and flexible ureterorenoscopy (URS are the most widely used modalities for the management of renal stones. In earlier series, treatment success of renal calculi assessed with KUB radiography, ultrasound, or intravenous pyelography which are less sensitive than CT that leads to be diversity of study results in reporting outcome. Residual fragments (RFs after interventional therapies may cause pain, infection, or obstruction. The size and location of RFs following SWL and PCNL are the major predictors for clinical significant symptoms and stone events requiring intervention. There is no consensus regarding schedule for followup of SWL, PCNL, and flexible URS. Active monitoring can be recommended when the stones become symptomatic, increase in size, or need intervention. RFs <4 mm after SWL and <2 mm after PCNL and flexible URS could be actively monitored on an annual basis with CT. Early repeat SWL and second-look endoscopy are recommended after primary SWL and PCNL, respectively. There is insufficient data for flexible URS, but RFs can be easily treated with repeat URS. Finally, medical therapy should be tailored based on the stone analysis and metabolic workup that may be helpful to prevent regrowth of the RFs.

  5. An evaluation on the environmental consequences of residual CFCs from obsolete household refrigerators in China

    International Nuclear Information System (INIS)

    2011-01-01

    Chlorofluorocarbons (CFCs) contained in household refrigerators consist mainly of CFC-11 and CFC-12, which will be eventually released into the environment. Consequentially, environmental releases of these refrigerants will lead to ozone depletion and contribute significantly to the greenhouse effect, if waste refrigerators are not disposed of properly. In the present paper, the potential release of residual CFCs and their substitutes from obsolete household refrigerators in China is examined, and their contributions to ozone depletion and greenhouse effect are compared with those of other recognized ozone-depleting substances (ODS) and greenhouse gases (GHGs). The results imply that annual potential amounts of released residual CFC-11 and CFC-12 will reach their maximums at 4600 and 2300 tons, respectively in 2011, and then decrease gradually to zero until 2020. Meanwhile, the amounts of their most widely used substitutes HCFC-141b and HFC-134a will keep increasing. Subsequently, the contribution ratio of these CFCs and their substitutes to ozone depletion will remain at 25% through 2011, and reach its peak value of 34% by 2018. The contribution to greenhouse effect will reach its peak value of 0.57% by 2010. Moreover, the contribution ratio of these CFCs to the total global release of CFCs will steadily increase, reaching its peak of 15% by 2018. Thus, this period from 2010 to 2018 is a crucial time during which residual CFCs and their substitutes from obsolete household refrigerators in China will contribute significantly to ozone depletion.

There is no doubt that EIA (Environmental Impact Analysis) on project is very different than EIA on plans. Obviously EIA on a sectorial plan is not an addition of singular EIA on project. The new main objectives shall be: identification of critical areas; identification of interaction between different projects and between different factors; identification of critical project. A methodology to quantify these objectives in matricial form is presented

    Nanotechnology show an increasing spread thanks to the special properties of nanomaterials (NM). Knowledge of the NM behavior and interactions with the environment and human health is still insufficient to assess the impact of the NM. A multidisciplinary, multidimensional and systemic such as that of the life cycle (Life Cycle Thinking - LCT), applied through the tool Life Cycle Assessment (LCA), is essential in environmental sustainability assessment of technologies, with some limitations that can be overcome through integration with other instruments such as, for example, non-linear models, analysis of flows of material, Risk Assessment (RA). This article offers a detailed analysis of the state and the main problems related to the application of LCA and RA to NM both separately and in combined use; They will then discuss the strategies and integrations needed to overcome the limitations of both methods and obtain robust assessments of the impacts on health and the environment [it

    2011-07-15

    Cultured meat (i.e., meat produced in vitro using tissue engineering techniques) is being developed as a potentially healthier and more efficient alternative to conventional meat. Life cycle assessment (LCA) research method was used for assessing environmental impacts of large-scale cultured meat production. Cyanobacteria hydrolysate was assumed to be used as the nutrient and energy source for muscle cell growth. The results showed that production of 1000 kg cultured meat requires 26-33 GJ energy, 367-521 m(3) water, 190-230 m(2) land, and emits 1900-2240 kg CO(2)-eq GHG emissions. In comparison to conventionally produced European meat, cultured meat involves approximately 7-45% lower energy use (only poultry has lower energy use), 78-96% lower GHG emissions, 99% lower land use, and 82-96% lower water use depending on the product compared. Despite high uncertainty, it is concluded that the overall environmental impacts of cultured meat production are substantially lower than those of conventionally produced meat.

    The environmental impacts of three alternative methods for disposal of Hanford defense wastes were analyzed in an environmental impact statement (EIS), DOE/EIS-0013. A fourth alternative, no disposal action, was included to satisfy CEQ regulations. Hanford defense waste differ dramatically from commercial nuclear wastes. The fuel elements are irradiated to very low burnups (by commercial standards), the fuel has all been processed (in some cases several times) to extract uranium and plutonium, much of the strontium and cesium has been removed and concentrated in capsules, and the remaining wastes have been highly diluted by processing and by neutralizing salts. The activity per unit volume is ∼ 1/1000 that of commercial spent fuel. Hanford waste is currently stored in a variety of forms and locations. It was categorized into six classes for analysis. The major radionuclides by waste class are shown. Numerous alternatives were considered for treating Hanford defense wastes. Of those studied, four were considered to be reasonable for detailed analysis. A highly abbreviated description of their salient features is presented: (1) geologic disposal; (2) in-place stabilization and disposal; (3) reference (combination disposal); and (4) no disposal action

    Healthcare is a significant contributor to environmental impact but this has received little attention. The typical laboratory uses far more energy and water per unit area than the typical office building. There is a need to sensitise laboratories to the importance of adopting good environmental practices. Since this comes at an initial cost, it is vital to obtain senior management support. Convincing management of the various tangible and intangible benefits that can accrue in the long run should help achieve this support. Many good environmental practices do not have a cost but will require a change in the culture and mind-set of the organisation. Continuing education and training are important keys to successful implementation of good practices. There is a need to undertake a rigorous cost-benefit analysis of every change that is introduced in going green. The adoption of good practices can eventually lead to ISO certification if this is desired. This paper provides suggestions that will allow a laboratory to start going green. It will allow the industry to enhance its corporate citizenship whilst improving its competitive advantage for long-term.

    Approximately 0.63 m 2 of SiO 2-based aerogel (0.02 g cm -3) was exposed for 18 months on the Mir Station to capture hypervelocity particles from both man-made and natural sources. Optical inspection revealed two major classes of hypervelocity impact features in the aerogel: (1) long, carrot-shaped tracks, well known from laboratory impact experiments, that exhibit a depth- ( t) to-diameter ( D) relationship of t/ D>10, typically 20-30, and (2) shallow pits ( t/ DCompositional analyses by SEM-EDS identified a variety of man-made and natural particles. A few natural particles were embedded in epoxy, microtomed, and analyzed by TEM. All were polymineralic aggregates that contained olivine exhibiting sharp electron-diffraction spots, and suggesting that the materials had experienced only minimal shock-deformation, if any. One natural particle contained olivine, augite, diopside, troilite, chromite/magnetite, and hercynite, the latter existing as pristine, undeformed octahedral crystals. The olivine in two of the particles were Fo 60-70 and Fo 39-53, and thus, more equilibrated than olivines in most stratospheric particles (Fo 80-100). These results illustrate that particle collections in Earth orbit are highly complementary to ground-based collections of cosmic dust.

    The NASA Stardust spacecraft deployed two collector trays, one dedicated to the collection of dust from Comet Wild 2, and the other for the capture of interstellar dust (ISD). The samples were returned successfully to Earth in 2006, and now provide an unprecedented opportunity for laboratory-based microanalysis of materials from the outer solar system and beyond. Results from the cometary sample studies have demonstrated that Wild 2 contains much more refractory condensate material and much less pristine extra-solar material than expected, which further indicates that there was significant transport of inner solar system materials to the Kuiper Belt in the early solar system [1]. The analysis of the interstellar samples is still in the preliminary examination (PE) phase, due to the level of difficulty in the definitive identification of the ISD features, the overall low abundance, and its irreplaceable nature, which necessitates minimally invasive measurements [2]. We present here coordinated microanalysis of the impact features on the Al foils, which have led to the identification of four impacts that are possibly attributable to interstellar dust. Results from the study of four ISD candidates captured in aerogel are presented elsewhere [2].

    Blade-stiffened, compression-loaded cover panels were designed, manufactured, analyzed, and tested. All panels were fabricated from IM6/1808I interleafed graphite-epoxy. An orthotropic blade stiffener and an orthotropic skin were selected to satisfy the design requirements for an advanced aircraft configuration. All specimens were impact damaged prior to testing. Experimental results were obtained for three- and five-stiffener panels. Analytical results described interlaminar forces caused by impact and predicted specimen residual strength. The analytical results compared reasonably with the experimental results for residual strength of the specimens.

  18. Environmental impact of nuclear fuel cycle operations

    International Nuclear Information System (INIS)

    Wilkinson, W.L.

    1989-09-01

    This paper considers the environmental impact of nuclear fuel cycle operations, particularly those operated by British Nuclear Fuels plc, which include uranium conversion, fuel fabrication, uranium enrichment, irradiated fuel transport and storage, reprocessing, uranium recycle and waste treatment and disposal. Quantitative assessments have been made of the impact of the liquid and gaseous discharges to the environment from all stages in the fuel cycle. An upper limit to the possible health effects is readily obtained using the codified recommendations of the International Commission on Radiological Protection. This contrasts with the lack of knowledge concerning the health effects of many other pollutants, including those resulting from the burning of fossil fuels. Most of the liquid and gaseous discharges result at the reprocessing stage and although their impact on the environment and on human health is small, they have given rise to much public concern. Reductions in discharges at Sellafield over the last few years have been quite dramatic, which shows what can be done provided the necessary very large investment is undertaken. The cost-effectiveness of this investment must be considered. Some of it has gone beyond the point of justification in terms of health benefit, having been undertaken in response to public and political pressure, some of it on an international scale. The potential for significant off-site impact from accidents in the fuel cycle has been quantitatively assessed and shown to be very limited. Waste disposal will also have an insignificant impact in terms of risk. It is also shown that it is insignificant in relation to terrestrial radioactivity and therefore in relation to the human environment. 14 refs, 5 figs, 2 tabs

    1992-01-01

    To better understand the nature of particulates in low-Earth orbit (LEO), and their effects on spacecraft hardware, we are analyzing residues found in impacts on the Long Duration Exposure Facility (LDEF) tray clamps. LDEF experiment trays were held in place by 6 to 8 chromic-anodized aluminum (6061-T6) clamps that were fastened to the spacecraft frame using three stainless steel hex bolts. Each clamp exposed an area of approximately 58 sq cm (4.8 cm x 12.7 cm x .45 cm, minus the bolt coverage). Some 337 out of 774 LDEF tray clamps were archived at JSC and are available through the Meteoroid & Debris Special Investigation Group (M&D SIG). Optical scanning of clamps, starting with Bay/Row A01 and working toward H25, is being conducted at JSC to locate and document impacts as small as 40 microns. These impacts are then inspected by Scanning Electron Microscopy/Energy Dispersive X-ray Analysis (SEM/EDXA) to select those features which contain appreciable impact residue material. Based upon the composition of projectile remnants, and using criteria developed at JSC, we have made a preliminary discrimination between micrometeoroid and space debris residue-containing impact features. Presently, 13 impacts containing significant amounts of unmelted and semi-melted micrometeoritic residues were forwarded to Centre National d'Etudes Spatiales (CNES) in France. At the CNES facilities, the upgraded impacts were analyzed using a JEOL T330A SEM equipped with a NORAN Instruments, Voyager X-ray Analyzer. All residues were quantitatively characterized by composition (including oxygen and carbon) to help understand interplanetary dust as possibly being derived from comets and asteroids.

    Scientific investigations have progressively refined our understanding of the influence of the environment on human health, and the many adverse impacts that human activities exert on the environment, from the local to the planetary level. Nonetheless, throughout the modern public health era, health has been pursued as though our lives and lifestyles are disconnected from ecosystems and their component organisms. The inadequacy of the societal and public health response to obesity, health inequities, and especially global environmental and climate change now calls for an ecological approach which addresses human activity in all its social, economic and cultural complexity. The new approach must be integral to, and interactive, with the natural environment. We see the continuing failure to truly integrate human health and environmental impact analysis as deeply damaging, and we propose a new conceptual model, the ecosystems-enriched Drivers, Pressures, State, Exposure, Effects, Actions or 'eDPSEEA' model, to address this shortcoming. The model recognizes convergence between the concept of ecosystems services which provides a human health and well-being slant to the value of ecosystems while equally emphasizing the health of the environment, and the growing calls for 'ecological public health' as a response to global environmental concerns now suffusing the discourse in public health. More revolution than evolution, ecological public health will demand new perspectives regarding the interconnections among society, the economy, the environment and our health and well-being. Success must be built on collaborations between the disparate scientific communities of the environmental sciences and public health as well as interactions with social scientists, economists and the legal profession. It will require outreach to political and other stakeholders including a currently largely disengaged general public. The need for an effective and robust science-policy interface has

    Municipal food waste (FW) represents 35-45% of household residual waste in Australia, with the nation generating 1.6Tg annually. It is estimated that 91% of this FW ends up in landfill. This study used life cycle assessment to determine and compare the environmental impact of seven contemporary FW management systems for two real-life jurisdictions; incorporating the complete waste service and expanding the system to include inert and garden waste. Although, no system exhibited a best ranking across all impact categories, FW digestion based systems were all revealed to have a lower global warming potential than composting and landfilling systems. Mechanical biological treatment, anaerobic co-digestion, and home composting all demonstrated the lowest environmental impacts for two or more of the environmental impact categories assessed. The assessment included market and technological specific variables and uncertainties providing a framework for robust decision making at a municipality level. Crown Copyright © 2017.

    Coffee is one of the most widely consumed beverages throughout the world. So far, many studies have shown the properties of coffee beverages, but little is known about its impacts on human and environmental health from its discard in the environment. So, the present work aims to investigate the mutagenic, genotoxic, cytotoxic and ecotoxic effects of leached (LE) and solubilized (SE) extracts from coffee waste, simulating the disposal of this residue in landfills and via sewage systems, respectively. Chemical analyses were also carried out. LE and SE induced mutagenicity in the TA98 Salmonella strain with and without exogenous metabolization (S9). In the TA100 only SE induced mutagenicity, what was observed without S9. An increase in the frequency of micronuclei was observed in HepG2 cell line after 3 and 24h of exposure to both extracts. No cytotoxic effects were observed in HepG2 cells by WST-1 assay. The EC50 values for the LE and SE were 1.5% and 11.26% for Daphnia similis, 0.12% and 1.39% for Ceriodaphnia dubia and 6.0% and 5.5% for Vibrio fischeri, respectively. Caffeine and several transition metals were found in both extracts. Coffee waste discarded in the environment may pose a risk to human and environmental health, since this compound can cause DNA damage and present toxicity to aquatic organisms.

  5. Peat 2003. Production, use, environmental impact

    International Nuclear Information System (INIS)

    2004-01-01

    This report discusses the use of peat for energy production and other purposes, laws and other regulations affecting peat production and use, environmental impact, market situation and international statistics regarding peat production. In Sweden, the extraction and use of peat for energy production is regulated by several laws. Harvesting concessions must be approved by the county council. All combustion plants must be reported, or verified by regional or central authorities, depending on the size of the plant. Most important in this process is to verify the maximum emission levels permitted for sulphur, nitrogen oxides, particles, etc. Since 1991, a law on municipal energy planning requires descriptions of environmental consequences. Thus, environmental considerations must govern energy planning. Energy taxation in Sweden was changed in 1993. At present, the sulphur tax on fuel peat amounts to SEK 30 per kg of sulphur. Nitrogen oxides are also subject to a tax of SEK 40 per emitted kg. For peat, energy and environmental taxes total SEK 0.02 per kWh, excluding VAT. Peat harvesting for the production of energy aroused interest in the early 1980s as a consequence of the increased energy prices. In 2003, about 2,628,000 cubic metres of fuel peat were harvested in Sweden. The fuel peat is used mainly for production of hot water in district heating plants. In 2003, the total use of fuel peat amounted to 4,0 TWh. In addition to fuel peat, about 1,825,000 cubic metres of peat litter (mainly for horticultural use) was produced. In 2003, imports amounted to 382,3000 metric tons or 1.3 million cubic metres of peat. Exports amounted to 103,000 metric tons, consisting primarily of peat for horticultural use. The peat market in Sweden is divided into the energy market and the cultivation market. Political decisions regarding combustion taxes have a great impact on the competitive advantages of different fuels. The major competitors to peat are coal, oil, and renewable energy

  6. Environmental risk assessment of registered insecticides in Iran using Environmental Impact Quotient (EIQ index

    Directory of Open Access Journals (Sweden)

    S. Moinoddini

    2016-05-01

    Full Text Available In the last decades, pesticides have been used extensively, in order to control pests and plant diseases, but negative impacts of pesticides caused several environmental problems and put human health in danger. In order to decrease environmental hazards of pesticide, risk of pesticide application should be measured briefly and precisely. In this study environmental impacts of registered insecticides in Iran which applied in 2001-2002, 2003-2004, 2004-2005, are considered using environmental impact quotient (EIQ index. Results showed that among considered insecticides, Imidacloprid, Fipronil and Tiodicarb, potentially (EIQ were the most hazardous insecticides, respectively. Taking rate of application and active ingredient of insecticide in to account, environmental impact (practical toxicity per cultivated hectare (EIQ Field of each provinces were investigated. In this regard, among different province of Iran, Kerman, Mazandaran and Golestan were in danger more than the others, respectively. Besides, considering the amount of agricultural production in provinces, environmental impact per ton of production were calculated for each provinces which three northern provinces of Mazandaran, Golestan and Guilan, respectively endure the most environmental impact per ton of production. Eventually based on environmental impact quotient, results demonstrated that majority of environmental impacts of insecticide in Iran were due to inadequate knowledge and also overuse of a few number of insecticides. Therefore, by improving knowledge about environmental impact of pesticides and also developing environmental friendly and ecological based methods, negative environmental impacts of insecticides will be reduced significantly.

  7. Life Cycle Environmental Impacts of Disinfection Technologies Used in Small Drinking Water Systems.

    2018-03-06

    Small drinking water systems serve a fifth of the U.S. population and rely heavily on disinfection. While chlorine disinfection is common, there is interest in minimizing chemical addition, especially due to carcinogenic disinfection byproducts and chlorine-resistant pathogens, by using ultraviolet technologies; however, the relative, broader environmental impacts of these technologies are not well established, especially in the context of small (water systems. The objective of this study was to identify environmental trade-offs between chlorine and ultraviolet disinfection via comparative life cycle assessment. The functional unit was the production of 1 m 3 of drinking water to U.S. Treatment included cartridge filtration followed by either chlorine disinfection or ultraviolet disinfection with chlorine residual addition. Environmental performance was evaluated for various chlorine contact zone materials (plastic, concrete, steel), ultraviolet validation factors (1.2 to 4.4), and electricity sources (renewable; U.S. average, high, and low impact grids). Performance was also evaluated when filtration and chlorine residual were not required. From a life cycle assessment perspective, replacing chlorine with UV was preferred only in a limited number of cases (i.e., high pumping pressure but filtration is not required). In all others, chlorine was environmentally preferred, although some contact zone materials and energy sources had an impact on the comparison. Utilities can use these data to inform their disinfection technology selection and operation to minimize environmental and human health impacts.

  9. Watershed management program. Final environmental impact statement

    International Nuclear Information System (INIS)

    1997-07-01

    Under the Northwest Power Act, BPA is responsible for mitigating the loss of fish and wildlife habitat caused by the development of the Federal Columbia River Power System. BPA accomplishes this mitigation by funding projects consistent with those recommended by the Northwest Power Planning Council (Council). The projects are submitted to the Council from Indian tribes, state agencies property owners, private conservation groups, and Federal agencies. Future watershed management actions with potential environmental impacts are expected to include in-channel modifications and fish habitat enhancement structures; riparian restoration and other vegetation management techniques; agricultural management techniques for crop irrigation, animal facilities, and grazing; road, forest, urban area, and recreation management techniques; mining reclamation; and similar watershed conservation actions. BPA needs to ensure that individual watershed management projects are planned and carried out with appropriate consistency across projects, jurisdictions, and ecosystems, as well as over time

  10. Quantification of environmental impacts of various energy technologies. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Selfors, A. [ed.

    1994-10-01

    This report discusses problems related to economic assessment of the environmental impacts and abatement measures in connection with energy projects. Attention is called to the necessity of assessing environmental impacts both in the form of reduced economic welfare and in the form of costs of abatement measures to reduce the impact. In recent years, several methods for valuing environmental impacts have been developed, but the project shows that few empirical studies have been carried out. The final report indicates that some important factors are very difficult to evaluate. In addition environmental impacts of energy development in Norway vary considerably from project to project. This makes it difficult to obtain a good basis for comparing environmental impacts caused by different technologies, for instance hydroelectric power versus gas power or wind versus hydroelectric power. It might be feasible however to carry out more detailed economic assessments of environmental impacts of specific projects. 33 refs., 1 fig., 4 tabs.

    International Nuclear Information System (INIS)

    1984-01-01

    As one of many activities TVA has undertaken to ensure an adequate supply of uranium for these plants, TVA has proposed to underground mine, through its operator, the uranium deposits located in the Canon de Marquez in McKinley County, New Mexico. Construction and operation of the underground mine would be expected to have the following environmental effects: (a) a temporary change in land use for 48.5 hectares from wildlife habitat and recreation to mineral extraction; (b) a minor alteration in topography near the proposed pond sites due to reclamation of waste rock piles; (c) minimal impacts on land due to limited vehicular traffic and road construction; (d) temporary depression of ground water levels in the Westwater Canyon Member of the Morrison Formation in the mine vicinity during mine life; (e) short-term project-induced impacts to surface water and shallow ground water quality; (f) a temporary decrease in air quality in the vicinity of the mining operations due to fugitive dust and exhaust emissions from combustion-driven mining and support vehicles and releases of radon and short-lived radon progeny from ventilation shafts and ore piles; (g) a temporary decrease of plant and animal species at the mine site; (h) a minor and temporary effect on aquatic systems downstream from the mine and settling ponds due to sedimentation; and (i) a minor increase of noise levels in the immediate vicinity of mine shafts and vents. The no action alternative and alternatives for securing uranium ore by other methods were considered but were found insufficient to meet TVA objectives. None of the alternatives explored were environmentally preferable. TVA also evaluated site specific alternatives including the following: different shaft and support building siting, mining techniques, and reclamation options. 25 figures, 20 tables

  13. 3.4 Environmental impacts: energy industry

    International Nuclear Information System (INIS)

    2004-01-01

    The subchapter 3.4 'Environmental impact of the energy industry' of the 7th state of the environment report analyzes the current situation in Austria and briefly describes the following aspects: environmental policy targets, uniform taxation of energy, use of renewable energy sources, efficient use of energy, energy input, electricity supply and input, energy input into space heating and air conditioning systems, and renewable energy. In 2002, the input of final energy was risen by about 5 % in comparison to 1998. During this period, the largest increments in final energy inputs were recorded in the mobility sector with + 9.4 %, and in the private households sector with + 8.3 % . The goods production sector showed a slight decrease of about 1.3 % between 1998 and 2002. The 'goods production', 'mobility' and 'private households' sectors combined require about 87 % of the total final energy input. The final energy input for space heating and hot water in 2001 was 5.7 % above the input in 1998. Energy supply from renewable energy sources rose by about 13.8 % in 2002 compared to 1998. Domestic electricity consumption (excluding consumption for pumped-storage systems) in 2002 was about 10.5 % above consumption in 1998. Physical imports and physical exports in 2002 increased about 32 % and 8.6 % correspondingly compared to 1999. (nevyjel)

    Crop residues and plant cover represent a pool of organic matter that can be used either to restore organic matter in soils, and therefore maintain soil fertility, or that can be valorized outside of the field (e.g. energy production). However, it is crucial that the exportation of residues is not done to the detriment of the system sustainability. Three long term experiments have been settled in the loamy region in Belgium. All of them are designed to study the effect of residues management by several tillage systems (conventional plowing versus reduced tillage) on the whole soil-water-plant system. SOLRESIDUS is a field experiment where we study the impact of crop residue management while in SOLCOUVERT and SOLCOUVERT-BIS, we study the impact of cover crop management. SOLRESIDUS was started in 2008. In this field, four contrasted crop residues managements are tested in order to contrast as much as possible the responses from the soil-water plant system. Two practices characterize the four modalities: soil tillage (ploughing at 25 cm depth or reduce tillage at 10 cm max) and residue management (exportation or restitution). SOLCOUVERT and SOLCOUVERT-BIS were started in 2012 and 2013 respectively. In those fields cover crop management is also diverse: destruction of the cover crop by winter ploughing, spring ploughing, strip tillage (with a chemical destruction if needed) or shallow tillage (with a decompaction before cover crop sowing). Although although the overall project aims at studying the impact of management on the whole soil-water-plant system, here we will only present the results concerning crop production (sugar beet) in SOLCOUVERT experiments. The presented data will include germination rate, crop development (biomass quantification and BBCH stages) weeds population, disease occurrence, pest occurrences, nitrogen uptake by plants, quality and quantity of harvested products.

    The Institute of Environmental Engineering at the University of Pannonia has undertaken the challenge to develop an online environmental information system. This system is able to receive and process the collected environmental data via Internet. The authors have attached importance to the presentation of the data and have included other comprehensible information for laymen as well in order to work out visualisation techniques that are expressive and attract attention for environmental questions through the developed information system. The ways of visualizing physical and chemical parameters of surface water and the effects of motorway construction were examined.

  11. Methods and techniques for prediction of environmental impact

    International Nuclear Information System (INIS)

    1992-04-01

    Environmental impact assessment (EIA) is the procedure that helps decision makers understand the environmental implications of their decisions. The prediction of environmental effects or impact is an extremely important part of the EIA procedure and improvements in existing capabilities are needed. Considerable attention is paid within environmental impact assessment and in handbooks on EIA to methods for identifying and evaluating environmental impacts. However, little attention is given to the issue distribution of information on impact prediction methods. The quantitative or qualitative methods for the prediction of environmental impacts appear to be the two basic approaches for incorporating environmental concerns into the decision-making process. Depending on the nature of the proposed activity and the environment likely to be affected, a combination of both quantitative and qualitative methods is used. Within environmental impact assessment, the accuracy of methods for the prediction of environmental impacts is of major importance while it provides for sound and well-balanced decision making. Pertinent and effective action to deal with the problems of environmental protection and the rational use of natural resources and sustainable development is only possible given objective methods and techniques for the prediction of environmental impact. Therefore, the Senior Advisers to ECE Governments on Environmental and Water Problems, decided to set up a task force, with the USSR as lead country, on methods and techniques for the prediction of environmental impacts in order to undertake a study to review and analyse existing methodological approaches and to elaborate recommendations to ECE Governments. The work of the task force was completed in 1990 and the resulting report, with all relevant background material, was approved by the Senior Advisers to ECE Governments on Environmental and Water Problems in 1991. The present report reflects the situation, state of

    2013-04-01

    Residual sludge coming from dimensional stones working plants (diamond framesaw and ganguesaw with abrasive shots processes) represents a problem for Stone Industries. In fact the cost connected to their landfilling amounts to more than 3% of operating costs of dimensional stone working plants. Furthermore their strict feature as waste to dump (CER code 010413) contrasts the EU principles of "resource preservation" and "waste recovery". The main problems related to their management are: size distribution (fine materials, potentially asphyxial), presence of heavy metals (due to the working processes) and TPH content (due to oil machines losses). Residual sludge, considered according to Italian Legislative Decree n.152/06, can be used, as waste, for environmental restoration of derelict land or in cement plants. It is also possible to think about their systematic treatment in consortium plats for the production of Secondary Raw Materials (SRM) or "New Products" (NP, eg. artificial loam, waterproofing materials, ....). The research evidences that, on the basis of a correct sludge management, treatment and characterization, economic and environmental benefits are possible (NP or SRM in spite of waste to dump). To individuate different applications of residual sludge in civil and environmental contexts, a geotechnical (size distribution, permeability, Atterberg limits, cohesion and friction angle evaluation, Proctor soil test) characterization was foreseen. The geotechnical tests were conducted on sludge as such and on three different mixes: - Mix 1 - Bentonite clay (5-10%) added to sludge a.s (90-95%); - Mix 2 - Sludge a.s. (90-80-70%) added to coarse materials coming from crushed dimensional stones (10-20-30%); - Mix 3 - Sludge a.s. (50-70%) mixed with sand, compost, natural loam (50-30% mixture of sand, compost, natural loam). The results obtained from the four sets of tests were fundamental to evaluate: - the characteristics of the original materials; - the chance

    Airflow over airfoils used on current commercial aircraft transitions from laminar to turbulent at relatively low chord positions. As a result, drag increases, requiring more thrust to maintain flight. An airfoil with increased laminar flow would experience reduced drag and a lower fuel burn rate. One of the objectives of NASA's Environmentally Responsible Aviation project is to identify and demonstrate technologies that will enable more environmentally friendly commercial aircraft. While more aerodynamically efficient airfoil shapes can be designed, surface contamination from ice, dirt, pollen, runway debris, and insect residue can degrade performance.

    2012-08-01

    Laboratory incubations were performed in order to evaluate the dissipation of the proherbicide isoxaflutole in seedbed layer soil samples from conventional and conservation tillage systems and in maize and oat residues left at the soil surface under conservation tillage. The effects of temperature and water pressure head on radiolabelled isoxaflutole degradation were studied for each sample for 21d. Mineralisation of isoxaflutole was low for all samples and ranged from 0.0% to 0.9% of applied (14)C in soil samples and from 0.0% to 2.4% of applied (14)C in residue samples. In soil samples, degradation half-life of isoxaflutole ranged from 9 to 26h, with significantly higher values under conservation tillage. In residue samples, degradation half-life ranged from 3 to 31h, with significantly higher values in maize residues, despite a higher mineralisation and bound residue formation than in oat residues. Whatever the sample, most of the applied (14)C remained extractable during the experiment and, after 21d, less than 15% of applied (14)C were unextractable. This extractable fraction was composed of diketonitrile, benzoic acid derivative and several unidentified metabolites, with one of them accounting for more than 17% of applied (14)C. This study showed that tillage system design, including crop residues management, could help reducing the environmental impacts of isoxaflutole. Copyright © 2012 Elsevier Ltd. All rights reserved.

    An Environmental Impact Directory System (EIDS) was proposed as a method for a computerized search of the widely distributed data files and models pertaining to energy-related environmental effects. To define the scope and content of the system, an example was prepared for the case of geothermal energy. The resulting sub-directory is known as GEIDs (Geothermal Environmental Impact Directory System). In preparing or reviewing an Environmental Impact Statement (EIS), the user may employ GEIDS as an extensive checklist to make sure he has taken into account all predictable impacts at any level of severity.

    The impacts of geothermal development projects are usually positive. However, without appropriate monitoring plans and mitigation actions firmly incorporated into the project planning process, there exists the potential for significant negative environmental impacts. The authors present five examples from Central America of environmental impacts associated with geothermal development activities. These brief case studies describe landslide hazards, waste brine disposal, hydrothermal explosions, and air quality issues. Improved Environmental Impact Assessments are needed to assist the developing nations of the region to judiciously address the environmental consequences associated with geothermal development

    2001-01-01

    This report discusses peat as a natural resource. It describes the peat land area, the peat harvest area, the use of peat for energy production and other purposes, laws and other regulations affecting peat production and use, environmental impact, market situation, trade, research and development, and the government grant to the peat industry. In Sweden, the extraction and use of peat for energy production is regulated by several laws. A company planning peat extraction must first apply for an examination concession. Then a harvesting concession must be approved by the county council. All combustion plants must be reported, or verified by regional or central authorities, depending on the size of the plant. Most important in this process is to verify the maximum emission levels permitted for sulphur, nitrogen oxides, particles, etc. Since 1991, a law on municipal energy planning requires descriptions of environmental consequences. Thus, environmental considerations must govern energy planning. Energy taxation in Sweden was changed in 1993. At present, the sulphur tax on fuel peat amounts to SEK 30 per kg of sulphur. Nitrogen oxides are also subject to a tax of SEK 40 per emitted kg. For peat, energy and environmental taxes total SEK 0.02 per kWh, excluding VAT. More than six millions hectares have been defined as peat land (with a peat layer of more than 30 cm) in Sweden, which means that about 15 per cent of the total land area consists of peat lands. Thinner peat layers (wet mineral soils) cover an additional 10 per cent of the land area. At the end of 1999 concessions for fuel peat harvesting had been granted for 45,000 hectares or 0.8 per cent of the total peat land area. Peat harvesting for the production of energy aroused interest in the early 1980s as a consequence of the energy crises. In 2000, about 1,372,000 cubic metres of fuel peat were harvested in Sweden. The fuel peat is used mainly for production of hot water in heating plants. In 2000, the total use

    Pentreath, R.J.

    2002-01-01

    The environmental impact of chemicals generally in the environment is a subject that has been approached in recent years in ways that are different in concept and practice. They range from chemical 'toxicity' and 'residual' risk assessments based on individuals, to broader based, ecological risk assessments. At the same time, approaches to considering what in the environment should be protected, and how, has also changed. Approaches to this subject vary from strict conservation of identified species and areas, to the more general concepts of wishing to maintain the biological diversity within and amongst all species and habitats, and of protecting large habitat areas against irreversible human damage. Against this background, approaches to the issue of the possible impact of radionuclides in the environment over the last decade or so have centred around the various statements made by the ICRP; either attempting to support them, or seeking to compensate for their perceived deficiencies. There have been arguments that, because man is an integral part of 'the environment', and is afforded such a high level of protection, then all other components of it would be axiomatically protected. There have also been calculations to demonstrate that, in hypothetical situations, if radionuclide concentrations in the environment were such that the 1 mSv a -1 dose limit to man was not exceeded, then the concentrations of radionuclides in the animals and plants in their food chain would therefore receive dose-rates less than those likely to cause them 'harm' at the population level. Some countries have been more direct. In the USA, dose 'standards' for the protection of populations of all aquatic animals have been introduced, and consideration is being given to the introduction of dose 'standards' for populations of all terrestrial plants and animals. The introduction of a set of 'no effects' dose-rate screening reference levels for different types of fauna, to be applied to

    2009-01-01

    Environmental impact assessment of development projects is a fundamental process, which main goal is to avoid that their construction and functioning, lead to serious and negative consequences on the environment. Some of the most important limitations of the models employed to assess environmental impacts, are the subjectivity of its parameters and weights, and the multicolineality among the variables, which represent high quantities of similar information. This work presents a multivariate statistical-based method that tries to diminish such limitations. For this purpose, environmental impact assessment, is valuated through different environmental impact attributes and environmental elements, synthesized in an environmental quality index (ICA in Spanish). ICA can be applied at different levels, such as at a project level, or applied only at a partial level on one or some environmental components.

    2002-01-01

    Full text:Over the past several years, great progress has been made in understanding and reducing the environmental impacts of offshore drilling wastes. Our understanding of sea floor impacts has been helped along by new environmental assessment tools such us computer modeling of sea floor deposition of drilling discharges, sediment profile imaging, and in situ sediment toxicity bioassays. To further reduce environmental impacts, new pollution prevention technologies have been developed that can shrink the environmental footprint of offshore drilling. These technologies reduce the total amount of drilling wastes discharged and include cuttings dryers and centrifuges that can reduce the drilling fluid content of drill cuttings to below 10 percent. In conclusion, the oil and gas industry is adopting more environmentally compatible drilling fluids, new environmental assessment tools and pollution prevention technologies that dramatically reduce the amount of drilling wastes discharged. Together, all of these elements have the potential to reduce environmental impacts of offshore drilling

    Some conceptual and practical elements related to environmental impact evaluation are described and related to the preparation of technical reports (environmental impact studies and environmental management plans) to be presented to environmental authorities for obtaining the environmental permits for development projects. In the first part of the document a summary of the main aspects of normative type is made that support the studies of environmental impact in Colombia. We propose a diagram for boarding and elaboration of the evaluation of environmental impact, which begins with the description of the project and of the environmental conditions in the area of the same. Passing then to identify the impacts through a method matricial and continuing with the quantitative evaluation of the same. For which we propose the use of the method developed by Arboleda (1994). Also we propose to qualify the activities of the project and the components of the environment in their relative importance, by means of a method here denominated agglomerate evaluation. Which allows finding those activities more impacting and the mostly impacted components. Lastly it is presented some models for the elaboration and presentation of the environmental management plans.

In Sweden, the extraction and use of peat for energy production is regulated by several laws. A company planning peat extraction must first apply for an examination concession. Then a harvesting concession must be approved by the county council. All combustion plants must be reported, or verified by regional or central authorities, depending on the size of the plant. Most important in this process is to verify the maximum emission levels permitted for sulphur, nitrogen oxides, particles, etc. At present, the sulphur tax on fuel peat amounts to SEK 30 per kg of sulphur (1 USD approx. 7.8 SEK). Nitrogen oxides are also subject to a tax of SEK 40 per emitted kg. For peat, energy and environmental taxes total SEK 0.02 per kWh, excluding VAT. Peat harvesting for the production of energy aroused interest in the early 1980s as a consequence of the energy crises. In 2002, about 2,885,000 cubic metres of fuel peat were harvested in Sweden. The fuel peat is used mainly for production of hot water in heating plants. In 2001, the total use of fuel peat amounted to 4.1 TWh. In addition to fuel peat, about 1,800,000 cubic metres of peat litter (mainly for horticultural use) was produced. In 2001, imports amounted to 329,311 metric tons or 1.1 million cubic metres of peat. Exports amounted to 91,000 metric tons, consisting primarily of peat for horticultural use. Fuel peat is used at district heating power plants. Political decisions regarding combustion taxes have a great impact on the competitive advantages of different fuels. The major competitors to peat are coal, oil, and renewable energy sources. Some companies are privately owned, while others are owned by municipalities, which also manage district heating plants and thereby integrate

The storage of residues resulting from the processing of uranium ores started in 1944, and by 1950 residues from a number of plants were received at the site. The residues, with a volume of about 18,000 m 3 , account for the bulk of the radioactivity, which is primarily due to Ra-226; because of the extraction of uranium from the ore, the amount of uranium remaining in the residues is quite small. An analysis of the environmental impact assessment and environmental compliance actions taken to date at this site and their effectiveness are discussed. This case study provides an illustrative example of the complexity of technical and nontechnical issues for a large radiative waste facility. 11 refs., 7 figs., 2 tabs

  16. Wildlife mitigation program. Draft environmental impact statement

    International Nuclear Information System (INIS)

    1996-08-01

    Bonneville Power Administration (BPA) is responsible for mitigating the loss of wildlife habitat caused by the development of the Federal Columbia River Power System. BPA accomplishes this mitigation by funding projects consistent with those recommended by the Northwest Power Planning Council (Council). The projects are submitted to the Council from Indian Tribes, state agencies, property owners, private conservation groups, and other Federal agencies. Future wildlife mitigation actions with potential environmental impacts are expected to include land acquisition and management, water rights acquisition and management, habitat restoration and enhancement, installation of watering devices, riparian fencing, and similar wildlife conservation actions. BPA needs to ensure that individual wildlife mitigation projects are planned and managed with appropriate consistency across projects, jurisdictions, and ecosystems, as well as across time. BPA proposes to standardize the planning and implementation of individual wildlife mitigation projects funded by BPA. Alternative 1 is the No Action alternative. Five standardizing alternatives are identified to represent the range of possible strategies, goals, and procedural requirements reasonably applicable to BPA-funded projects under a standardized approach to project planning and implementation. All action alternatives are based on a single project planning process designed to resolve site-specific issues in an ecosystem context and to adapt to changing conditions and information

    2012-10-01

    Rotary kiln incinerators and cement kilns are two energy intensive processes, requiring high temperatures that can be obtained by the combustion of fossil fuel. In both processes, fossil fuel is often substituted by high or medium calorific waste to avoid resource depletion and to save costs. Two types of industrial calorific waste streams are considered: automotive shredder residue (ASR) and meat and bone meal (MBM). These waste streams are of current high interest: ASR must be diverted from landfill, while MBM can no longer be used for cattle feeding. The environmental impact of the incineration of these waste streams is assessed and compared for both a rotary kiln and a cement kiln. For this purpose, data from an extensive emission inventory is applied for assessing the environmental impact using two different modeling approaches: one focusing on the impact of the relevant flows to and from the process and its subsystems, the other describing the change of environmental impact in response to these physical flows. Both ways of assessing emphasize different aspects of the considered processes. Attention is paid to assumptions in the methodology that can influence the outcome and conclusions of the assessment. It is concluded that for the incineration of calorific wastes, rotary kilns are generally preferred. Nevertheless, cement kilns show opportunities in improving their environmental impact when substituting their currently used fuels by more clean calorific waste streams, if this improvement is not at the expense of the actual environmental impact.

  20. A qualitative method proposal to improve environmental impact assessment

    International Nuclear Information System (INIS)

    Toro, Javier; Requena, Ignacio; Duarte, Oscar; Zamorano, Montserrat

    2013-01-01

    In environmental impact assessment, qualitative methods are used because they are versatile and easy to apply. This methodology is based on the evaluation of the strength of the impact by grading a series of qualitative attributes that can be manipulated by the evaluator. The results thus obtained are not objective, and all too often impacts are eliminated that should be mitigated with corrective measures. However, qualitative methodology can be improved if the calculation of Impact Importance is based on the characteristics of environmental factors and project activities instead on indicators assessed by evaluators. In this sense, this paper proposes the inclusion of the vulnerability of environmental factors and the potential environmental impact of project activities. For this purpose, the study described in this paper defined Total Impact Importance and specified a quantification procedure. The results obtained in the case study of oil drilling in Colombia reflect greater objectivity in the evaluation of impacts as well as a positive correlation between impact values, the environmental characteristics at and near the project location, and the technical characteristics of project activities. -- Highlights: • Concept of vulnerability has been used to calculate the importance impact assessment. • This paper defined Total Impact Importance and specified a quantification procedure. • The method includes the characteristics of environmental and project activities. • The application has shown greater objectivity in the evaluation of impacts. • Better correlation between impact values, environment and the project has been shown

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

    2011-07-27

    The principles of modern pesticide residue chemistry were articulated in the 1950s. Early authors pointed out the advantages of systematizing and standardizing analytical methods for pesticides so that they could be widely practiced and the results could be reproduced from one laboratory to the next. The availability of improved methods has led to a much more complete understanding of pesticide behavior and fate in foods and the environment. Using methods based largely upon gas chromatography (GC) and high-performance liquid chromatography (HPLC) coupled increasingly with mass spectrometry (MS) and MS(n) as the detection tool, residues can be measured at parts per billion levels and below in a variety of food and environmental matrices. Development of efficient extraction and cleanup methods, techniques such as ELISA, efficient sample preparation techniques such as QuEChERS, and automated laboratory and field instrumentation has also contributed to the tools available for use in modern pesticide residue analysis. As a result, great strides have been made in improving food and worker safety and in understanding environmental behavior and fate of pesticides. There are many challenges remaining in the field of pesticide residue chemistry that will continue to stimulate analytical chemists. New chemistries are emerging, often patterned on complex natural products. Analyzing for the parent chemicals and potentially multiple breakdown products will require analytical ingenuity. The development of more sensitive bioassays and knowledge of unintended side effects will challenge residue chemistry as well, as in the case of following the fate of environmental endocrine disruptors associated with some pesticides as well as nonpesticide contaminants from packaging materials and other familiar articles. Continued funding and other resources to ensure better training, international cooperation, and accelerated research and development activities will be a constant need in

    The research findings fill a gap in the body of knowledge by presenting an effective way to evaluate the significance of on-site environmental impacts of municipal engineering works prior to the construction stage. First, 42 on-site environmental impacts of municipal engineering works were identified by means of a process-oriented approach. Then, 46 indicators and their corresponding significance limits were determined on the basis of a statistical analysis of 25 new-build and remodelling municipal engineering projects. In order to ensure the objectivity of the assessment process, direct and indirect indicators were always based on quantitative data from the municipal engineering project documents. Finally, two case studies were analysed and found to illustrate the practical use of the proposed model. The model highlights the significant environmental impacts of a particular municipal engineering project prior to the construction stage. Consequently, preventive actions can be planned and implemented during on-site activities. The results of the model also allow a comparison of proposed municipal engineering projects and alternatives with respect to the overall on-site environmental impact and the absolute importance of a particular environmental aspect. These findings are useful within the framework of the environmental impact assessment process, as they help to improve the identification and evaluation of on-site environmental aspects of municipal engineering works. The findings may also be of use to construction companies that are willing to implement an environmental management system or simply wish to improve on-site environmental performance in municipal engineering projects. -- Highlights: • We present a model to predict the environmental impacts of municipal engineering works. • It highlights significant on-site environmental impacts prior to the construction stage. • Findings are useful within the environmental impact assessment process. • They also

    Richter, B. D.

    2017-12-01

    One of the most ecologically disruptive impacts of dams is their alteration of natural river flow variability. Opportunities exist for modifying the operations of existing dams to recover many of the environmental and social benefits of healthy ecosystems that have been compromised by present modes of dam operation. The potential benefits of dam "re-operation" include recovery of fish, shellfish, and other wildlife populations valued both commercially and recreationally, including estuarine species; reactivation of the flood storage and water purification benefits that occur when floods are allowed to flow into floodplain forests and wetlands; regaining some semblance of the naturally dynamic balance between river erosion and sedimentation that shapes physical habitat complexity, and arresting problems associated with geomorphic imbalances; cultural and spiritual uses of rivers; and many other socially valued products and services. Assessing the potential benefits of dam re-operation begins by characterizing the dam's effects on the river flow regime, and formulating hypotheses about the ecological and social benefits that might be restored by releasing water from the dam in a manner that more closely resembles natural flow patterns. These hypotheses can be tested by implementing a re-operation plan, tracking the response of the ecosystem, and continually refining dam operations through adaptive management. This presentation will highlight a number of land and water management strategies useful in implementing a dam re-operation plan, with reference to a variety of management contexts ranging from individual dams to cascades of dams along a river to regional energy grids. Because many of the suggested strategies for dam re-operation are predicated on changes in the end-use of the water, such as reductions in urban or agricultural water use during droughts, a systemic perspective of entire water management systems will be required to attain the fullest possible

  2. Griffith energy project draft environmental impact statement

    International Nuclear Information System (INIS)

    1998-10-01

    Griffith Energy Limited Liability Corporation (Griffith) proposes to construct and operate the Griffith Energy Project (Project), a natural gas-fired, combined cycle power plant, on private lands south of Kingman, Arizona. The Project would be a merchant plant which means that it is not owned by a utility and there is currently no long-term commitment or obligation by any utility to purchase the capacity and energy generated by the power plant. Griffith applied to interconnect its proposed power plant with the Western Area Power Administration's (Western) Pacific Northwest-Pacific Southwest Intertie and Parker-Davis transmission systems. Western, as a major transmission system owner, needs to provide access to its transmission system when it is requested by an eligible organization per existing policies, regulations and laws. The proposed interconnection would integrate the power generated by the Project into the regional transmission grid and would allow Griffith to supply its power to the competitive electric wholesale market. Based on the application, Western's proposed action is to enter into an interconnection and construction agreement with Griffith for the requested interconnections. The proposed action includes the power plant, water wells and transmission line, natural gas pipelines, new electrical transmission lines and a substation, upgrade of an existing transmission line, and access road to the power plant. The existing environmental resource conditions in the Project area and the potential impacts on the resources by the proposed action and alternatives are described. Construction of segments of the transmission lines and a proposed natural gas pipeline also require a grant of right-of-way across Federal lands administered by the Bureau of Land Management

    2017-09-01

    The beneficial recycle of drinking water treatment residue (DWTR) in environmental remediation has been demonstrated in many reports. However, the lack of information concerning the potential toxicity of dewatered DWTR hinders its widespread use. The present study examined the ecotoxicity of dewatered aluminum (Al) and iron (Fe) DWTR leachates to a green alga, Chlorella vulgaris. Data from the variations of cell density and chlorophyll a content suggested that algal growth in DWTR leachates was inhibited. The algal cellular oxidation stress was initially induced but completely eliminated within 72 h by antioxidant enzymes. The expression of three photosynthesis-related algae genes (psaB, psbC, and rbcL) also temporarily decreased (within 72 h). Moreover, the algal cells showed intact cytomembranes after exposure to DWTR leachates. Further investigation confirmed that inhibition of algal growth was due to DWTR-induced phosphorus (P) deficiency in growth medium, rather than potentially toxic contaminants (e.g. copper and Al) contained in DWTR. Interestingly, the leachates could potentially promote algal growth via increasing the supply of new components (e.g. calcium, kalium, magnesium, and ammonia nitrogen) from DWTR. In summary, based on the algae toxicity test, the dewatered Fe/Al DWTR was nontoxic and its environment recycling does not represent an ecotoxicological risk to algae.

    2017-01-01

    Full Text Available Coal power plants constitute an important component of the energy mix in many countries. However, coal power plants can cause several environmental risks such as: climate change and biodiversity loss. In this study, a tool has been proposed to calculate the environmental impact of a coal-fired thermal power plant in operation by using multi-criteria scoring and fuzzy logic method. We take into account the following environmental parameters in our tool: CO, SO2, NOx, particulate matter, fly ash, bottom ash, the cooling water intake impact on aquatic biota, and the thermal pollution. In the proposed tool, the boundaries of the fuzzy logic membership functions were established taking into account the threshold values of the environmental parameters which were defined in the environmental legislation. Scoring of these environmental parameters were done with the statistical analysis of the environmental monitoring data of the power plant and by using the documented evidences that were obtained during the site visits. The proposed method estimates each environmental impact factor level separately and then aggregates them by calculating the Environmental Impact Score (EIS. The proposed method uses environmental monitoring data and documented evidence instead of using simulation models. The proposed method has been applied to the 4 coal-fired power plants that have been operation in Turkey. The Environmental Impact Score was obtained for each power plant and their environmental performances were compared. It is expected that those environmental impact assessments will contribute to the decision-making process for environmental investments to those plants. The main advantage of the proposed method is its flexibility and ease of use.

    2015-08-01

    Full Text Available Environmental studies in Brazil are required to obtain a license to perform activities that use environmental resources or have the potential to cause environmental degradation, but the quality and effectiveness of these studies have been widely questioned. It is the licensing body’s duty to define the technical studies required for licensing. However, in the case of enterprises that have the potential to cause significant degradation, Environmental Impact Statement (EIS and Environmental Impact Report (EIR must always be requested. The EIS/EIR is composed of several parts, among them standing out the environmental diagnostic, which it is the major part of the environmental studies and is the part that demands more resources to be carried out; in addition, its information subsidizes the later stages: prediction and assessment of environmental impacts, mitigation measures, compensatory and monitoring plans.The aim of this study was to analyze the problems usually present in the environmental assessment of the environmental impact studies as the perception of IBAMA environmental analyst. Data collection for this research was done through the application of an electronic questionnaire to IBAMA environmental analysts, achieving a sample of 74 questionnaires from a population of 354 analysts. As methodological basis, cluster analysis and the nonparametric Mann-Whitney test were applied. The results indicated that the problems related to coordination of EIAs are critical and they seem to last for at least a decade according to the articles identified.

    The use of economic valuation methods to assess environmental impacts of projects and policies has grown considerably in recent years. However, environmental valuation appears to have developed independently of regulations and practice of environmental impact assessment (EIA), despite its potential benefits to the EIA process. Environmental valuation may be useful in judging significance of impacts, determining mitigation level, comparing alternatives and generally enabling a more objective analysis of tradeoffs. In China, laws and regulations require the use of environmental valuation in EIA, but current practice lags far behind. This paper assesses the problems and prospects of introducing environmental valuation into the EIA process in China. We conduct four case studies of environmental economic impact assessment (EEIA), three of which are based on environmental impact statements of construction projects (a power plant, a wastewater treatment plant and a road construction project) and one for a regional pollution problem (wastewater irrigation). The paper demonstrates the potential usefulness of environmental valuation but also discusses several challenges to the introduction and wider use of EEIA, many of which are likely to be of relevance far beyond the Chinese context. The paper closes with suggesting some initial core elements of an EEIA guideline

    2012-03-01

    Full Text Available Today, tall building is a phenomenon that the world particularly large cities are facing. The tall buildings in order to exploit the land with having the negative affects in the environment create new problems including increasing congestion population, environmental pollution, reduce citizen access to fresh air and sunlight. However, regarding to population increasing and land shortage, tall buildings could not be avoided. This paper investigates the relationship of tall buildings with urban air pollution as well as the possible reducing of negative affects of tall building on environmental pollution with respect to geographical position, technicalrules, immunization, green space, direct of wind, appropriate distance to other buildings, design in terms of visibility and landscape and urban appearance were reviewed. The study showed that the tall buildings cause increasing the air pollution in large urban area due to changing in wind and its direction and also congestion of tall buildings as a pollution sources. Therefore some techniques to design the tall building must be considered to reduce the negative affects of the tall buildings on environmental pollution. Unfortunately the lack of the construction roles in term of environmental protection and also control of the rules in construction process causing the environmental pollution particularly air pollution. It is suggested that the re-evaluate of the rules with restricted control can improve the air quality in the large cities and also utilization of green spaces in floors and roofs of buildings as environmentally friendly buildings which are attempt to reduce environmental problems.

    Population distribution, atmospheric change, X/Q, characteristics of terrestrial ecosystem around Seoul site were surveyed. Environmental radiation and radioactivities such as grossα, grossβ, Cs-137, Sr-90 and H-3 of various environmental samples were analyzed. The values of environmental radiation dose tended to increase gradually in the light of the recent five years' results of environmental radiation monitoring around the nuclear power plants from 1980 to 1984, however, the changes were not significant. In addition, continuous assessment of environmental radiation monitoring on the roofs of main building and life science building at KAERI showed that the environmental radiation dose tended to increase a little during the night time. Judging from the above results, it is concluded that environmental contamination level by radioactive materials could be ignored in the case of radioisotope production or experiment using radioisotopes except the release of gaseous radioactive materials such as Ar-41 of short half life by the operation of nuclear reactor.

  2. Environmental DNA from Residual Saliva for Efficient Noninvasive Genetic Monitoring of Brown Bears (Ursus arctos.

    Directory of Open Access Journals (Sweden)

    Rachel E Wheat

    Full Text Available Noninvasive genetic sampling is an important tool in wildlife ecology and management, typically relying on hair snaring or scat sampling techniques, but hair snaring is labor and cost intensive, and scats yield relatively low quality DNA. New approaches utilizing environmental DNA (eDNA may provide supplementary, cost-effective tools for noninvasive genetic sampling. We tested whether eDNA from residual saliva on partially-consumed Pacific salmon (Oncorhynchus spp. carcasses might yield suitable DNA quality for noninvasive monitoring of brown bears (Ursus arctos. We compared the efficiency of monitoring brown bear populations using both fecal DNA and salivary eDNA collected from partially-consumed salmon carcasses in Southeast Alaska. We swabbed a range of tissue types from 156 partially-consumed salmon carcasses from a midseason run of lakeshore-spawning sockeye (O. nerka and a late season run of stream-spawning chum (O. keta salmon in 2014. We also swabbed a total of 272 scats from the same locations. Saliva swabs collected from the braincases of salmon had the best amplification rate, followed by swabs taken from individual bite holes. Saliva collected from salmon carcasses identified unique individuals more quickly and required much less labor to locate than scat samples. Salmon carcass swabbing is a promising method to aid in efficient and affordable monitoring of bear populations, and suggests that the swabbing of food remains or consumed baits from other animals may be an additional cost-effective and valuable tool in the study of the ecology and population biology of many elusive and/or wide-ranging species.

  3. Detection and quantification of residues and metabolites of medicinal products in environmental compartments, food commodities and workplaces. A review.

    Bottoni, Paola; Caroli, Sergio

    2015-03-15

    The toxicological assessment of medicinal products (MPs) and their residues and metabolites in the environment have become a challenging task worldwide. The contamination of environmental compartments, biota, workplace, foodstuff and feedstuff by residues and metabolites of these substances poses a risk to human health which is still far from being fully understood. On the other hand, existing analytical methods not always possess sufficient detection power to quantify residues of MPs at very low concentrations. This review sets forth some of the most significant contributions made in this field over the past decade with a special focus on novel fit-for-purpose analytical approaches for the detection, identification and quantification of these pollutants and the assessment of their noxious potential for human beings and the environment.

    As part of a research contract in the targeted project 'Disposal of solid residues arising from coal' funded by the European Commission (ECSC contract 7220-ED/070), the Departamento de Impacto Ambiental de la Energia of the Centro de Investigaciones Energeticas Medioambientales y Tecnologicas (DIAE/CIEMAT), QuantiSci, the Laboratorio de Informatica of the Universidad Politecnica de Madrid (UPM) and the Departamento de Ingenieria Quimica y Ambiental of the Universidad de Sevilla have developed and tested a methodology, based on the SACo (Safety Assessment Comparison) methodology previously developed by QuantiSci and CIEMAT, that is considered to be appropriate for assessing and comparing reuse and disposal strategies of solid residues generated from the coal fuel cycle. The first phase of the project consisted of a review of solid residues produced in the coal fuel cycle, identifying contaminants that affect management of these residues from a physical and chemical point of view. Additionally, management options as well as environmental impacts associated with the reuse and disposal of the residues have been analysed together with previously used assessment methods. This Methodology framework has been applied to two test cases and is being applied to real cases in projects other than the targeted project. Some preliminary results have been obtained. 34 refs.; 5 figs.; 17 tabs.

  8. Qualitative assessment of environmental impacts through fuzzy logic

    International Nuclear Information System (INIS)

    Peche G, Roberto

    2008-01-01

    The vagueness of many concepts usually utilized in environmental impact studies, along with frequent lack of quantitative information, suggests that fuzzy logic can be applied to carry out qualitative assessment of such impacts. This paper proposes a method for valuing environmental impacts caused by projects, based on fuzzy sets theory and methods of approximate reasoning. First, impacts must be described by a set of features. A linguistic variable is assigned to each feature, whose values are fuzzy sets. A fuzzy evaluation of environmental impacts is achieved using rule based fuzzy inference and the estimated fuzzy value of each feature. Generalized modus ponens has been the inference method. Finally, a crisp value of impact is attained by aggregation and defuzzification of all fuzzy results

    2003-01-01

    A strategic planning process has been implemented at the Brazilian Agricultural Research Agency (Embrapa) to introduce sustainable agriculture concepts in all steps of Research and Development (R and D). An essential part of the devised mission statement called for the impact assessment of all technology innovation resulting from R and D, under field conditions (ex-post). However, methods for impact assessment of technology innovations at the farmstead level appropriate for the institutional context were lacking. The environmental impact assessment (EIA) system (AMBITEC-AGRO) developed to attend that demand is composed by a set of weighing matrices constructed in an electronic spreadsheet. Impact indicators are evaluated in the field in an interview/survey, and weighed according to their spatial scale and importance toward effecting environmental impacts. The results of these weighing procedures are expressed graphically in the assessment spreadsheets. Finally, the indicator evaluations are composed into an Environmental Impact Index for the agricultural technology innovation

    In the United States, recent environmental regulations will likely result in the removal of nearly 30 GW of oil and coal-fired generation from the power grid, mostly in the Eastern Interconnection (EI). The effects of this transition on voltage stability and transmission line flows have previously not been studied from a system-wide perspective. This report discusses the results of power flow studies designed to simulate the evolution of the EI over the next few years as traditional generation sources are replaced with environmentally friendlier ones such as natural gas and wind.

    2010-01-01

    This document presents the synthesis of my research work contributing to the development of an integrated methodology of environmental impact assessment for energy pathways. In the context of world globalization, environmental impact assessments issues are highly linked with the following questioning: Which environmental impacts? for which demand? at which location? at which temporal scale? My work is built upon the definition of a conceptual framework able to handle these issues and upon its progressive implementation. The integration of the spatial and temporal issues within the methodology are key elements. Fundamental cornerstones of this framework are presented along the DPSIR concept (Driving forces, Pressures, State, Impacts, Responses). They cover a comprehensive analysis of the limits and the relevance of life cycle analysis and the development of a geo-spatialized environmental performance approach for an electrical production pathway. Perspectives linked with the development of this integrated methodology are detailed for energy pathways. (author)

    Substantial improvements have been perceived in surgical results following major lower limb amputation, but there remains observed variation in amputation quality for patients referred for prosthetic rehabilitation from different hospitals. To assess various elements that influence residual limb quality and evaluate their impact on progress through initial prosthetic rehabilitation and mobility outcome after rehabilitation. Clinical survey. A revised 10-item residual limb scoring system was used to survey a succession of 95 primary amputees with transtibial and transfemoral amputations (100 residual limbs) presenting for rehabilitation. The majority of residual limbs scored highly, supporting the perception of generally good amputation quality. There were significant differences in average residual limb scores between some hospitals. The overall scores showed weak or minimal correlation to progress through rehabilitation and mobility outcome but residual limbs scoring higher in seven of the items of the score showed significant advantages in key aspects of progress or mobility at discharge. There is need for continued collaboration between surgeons and rehabilitation centres to ensure consistent high standards. The revised residual limb score used in this survey needs further refinement for future use. Clinical relevance Residual limb quality is an important component influencing prosthetic rehabilitation. This survey of residual limbs at one Rehabilitation Centre suggests encouragingly good surgical results but highlights differences between hospitals. A particular issue is the need for effective collaboration between surgeons and prosthetic rehabilitation professionals to optimise residual limb preparation.

  12. Quantification of the environmental impact of different dietary protein choices.

    Science.gov (United States)

    Reijnders, Lucas; Soret, Sam

    2003-09-01

    Quantitative environmental evaluations of meat, fresh vegetables, and processed protein based on soybeans suggest that the environmental burden of vegetarian foods is usually relatively low when production and processing are considered. The environmental comparison of cheese varieties made from cow milk and directly from lupine and the evaluation of energy inputs in fish protein and vegetable protein also suggest an environmental advantage for vegetarian food. In the evaluation of processed protein food based on soybeans and meat protein, a variety of environmental impacts associated with primary production and processing are a factor 4.4-> 100 to the disadvantage of meat. The comparison of cheese varieties gives differences in specific environmental impacts ranging between a factor 5 and 21. And energy use for fish protein may be up to a factor 14 more than for protein of vegetable origin. Assessment suggests that on average the complete life cycle environmental impact of nonvegetarian meals may be roughly a factor 1.5-2 higher than the effect of vegetarian meals in which meat has been replaced by vegetable protein. Although on average vegetarian diets may well have an environmental advantage, exceptions may also occur. Long-distance air transport, deep-freezing, and some horticultural practices may lead to environmental burdens for vegetarian foods exceeding those for locally produced organic meat.

  13. Environmental impacts of China's WTO-accession

    2008-01-01

    China's accession to the WTO in 2001 completed the country's entry into the global economy. We investigate environmental implications of WTO-accession. There are several hypotheses in this area: The scale hypothesis says that production is scaled up and in turn, pollution increases. The technique hypothesis says that production methods become cleaner and pollution decreases. The composition hypothesis says that composition of industries changes and pollution reflects the new composition. We analyse the relative strength of the hypotheses by means of an environmental CGE-model, and in the case of air pollution find support for a composition effect in favour of clean industries. Thanks to the composition effect, emissions to air of greenhouse gases fall. Emissions of particles and SO 2 also fall, but emissions of NO x and VOC rise. Since particle and SO 2 -emissions fall we estimate that public health improves. (author)

    Transgenic plant varieties are grown since 1996 on surfaces increasing each year. They covered 114 million hectares worldwide in 2007, which shows their success among the farmers in developed as well as developing countries, despite the propaganda campaigns of the environmental movements and advocates of decline. The first transgenic crops (soybean, corn, coton and rapeseed) offer benefits in terms of health, economy and environment. Europe and especially France, which reject this technology, sentence their research to death and penalize their agriculture.

  17. Is environmental impact assessment regulation a 'burden' to private firms?

    International Nuclear Information System (INIS)

    Annandale, David; Taplin, Ross

    2003-01-01

    The impact of environmental regulation on macroeconomic performance has been studied in some depth over the last 15 years. Similarly, impact on profit performance, investment intention and location decisions of firms has also been studied, although in less depth. There has been less academic interest, however, in the impact that environmental regulation has on the strategic objectives of companies. This article reports on a research project that focused on the impact that environmental approvals regulation (predominantly environmental impact assessment, EIA) has on proposed new development in the international mining sector. Based on a large and externally valid survey of senior mining company executives in Australia and Canada in the late 1990s, the research indicated that a significant majority of firms consider the environmental approvals process to be an important determinant of investment strategy. An initial reaction to these figures might suggest that the majority of respondents believe the environmental approvals process to be a negative influence. However, further questioning indicated that only a small proportion of companies in both countries thought of the environmental approvals process as an impediment to development. Instead, it is clear that most firms see EIA as a catalyst for integrating environmental design into the early planning of a project, thereby alleviating the need to spend money on overcoming environmental problems once a poorly designed project has been commissioned. The somewhat surprising conclusion that companies see environmental approvals regulation as important, but as an encouragement to development rather than as an impediment, goes against much previous industry and academic comment and, at least in relation to the mining sector, refutes the idea that EIA is ''burdensome''

  19. Environmental Impact of Natural Gas Hydrate Production

    Science.gov (United States)

    Max, M. D.; Johnson, A. H.

    2017-12-01

    Unmet conventional energy demand is encouraging a number of deep energy importing nations closer to production of their potentially very large Natural Gas Hydrate (NGH) resources. As methane and other natural gases are potent greenhouse gases, concerns exist about the possible environmental risks associated NGH development. Accidental of natural gas would have environmental consequences. However, the special characteristics of NGH and production models indicate a very low environmental risk from the reservoir to the deepwater wellhead that is much lower than for conventional deepwater gas. NGH is naturally stable in its solid form in the reservoir and shutting in the gas can be achieved by stopping NGH conversion and gas production in the reservoir. Rapid shut down results in re-crystallization of gas and stabilization of the reservoir through NGH reformation. In addition, new options for innovative technologies have the potential to allow safe development of NGH at a fraction of the current estimated cost. Gas produced from NGH is about the same as processed conventional gas, although almost certainly more pure. Leakage of gas during transport is not a production issue. Gas transport leakage is a matter for best practices regulation that is rigorously enforced.

  20. Carbon Capture and Sequestration. Potential Environmental Impacts

    Energy Technology Data Exchange (ETDEWEB)

    Johnston, P.; Santillo, D. [Greenpeace Research Laboratories, University of Exeter, Prince of Wales Road, Exeter, EX4 4PS (United Kingdom)

    2003-02-01

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

  1. The impact of supply management on environmental performance outcomes

    2004-12-01

    Environmentally responsible manufacturing is concerned with minimizing the environmental impact of products from development to end-of-life disposal or remanufacture. Environmental pressures from customers, regulation, legislation and competition have made organizations more aware of the impact that products have on the natural environment. This study focuses on environmental concerns during the early stages of product design. We examine these concerns with a specific focus on the involvement of supply management personnel, inter-organizational supplier relationships and a determination of how environmental issues affect supplier selection and supply base management. The literature on environmental supplier and purchasing involvement in product development and environmental supplier selection criteria and codes of conduct is reviewed. Following this, secondary data from the websites of environmentally proactive organizations will be gathered to examine what type of tracking is used for suppliers. Finally, discussions with proactive organizations will be presented during the conference that explore the role of supply management personnel in capturing, measuring, quantifying and reporting on the environmental costs and benefits associated with its suppliers. This research provides insights into how the involvement of supply management can improve the environmental performance outcomes of an organization.

    2008-01-01

    A simple analysis method has been developed for predicting the residual compression strength of impact-damaged sandwich panels. The method is tailored for honeycomb core-based sandwich specimens that exhibit an indentation growth failure mode under axial compression loading, which is driven largely by the crushing behavior of the core material. The analysis method is in the form of a finite element model, where the impact-damaged facesheet is represented using shell elements and the core material is represented using spring elements, aligned in the thickness direction of the core. The nonlinear crush response of the core material used in the analysis is based on data from flatwise compression tests. A comparison with a previous analysis method and some experimental data shows good agreement with results from this new approach.

    Sen, P.; Chakraborty, K.

    1994-01-01

    Surface coal mines being the largest contributor to the national coal production, the study of environmental impacts due to this becomes mandatory as it will help in proper planning and safe operations of the mine in an environmentally compatible manner. Within the scope of this paper, a model for preparation of comprehensive environmental impact assessment (EIA) by utilising a new evaluation methodology leading to determination of Environmental Quality Designation an index has been developed and this model has been validated by using data from a running surface coal mine in Wardha Valley Coalfield. Based on this exercise, the overall impact of the surface coal mine under consideration on environment indicates a medium level and accordingly the control measures have to be planned. Thus repair to the environment has to be made a concurrent activity with mining i.e. to say we have to design with nature not against it

    Assessment of environmental impact represents one of the most formalized examples of interdisciplinary approach. After more then a century from the introduction of the concept of environmental impact assessment, this undertaking still represents an amalgamation of mini-studies based on pre-determined approaches rather than a genuine integrated document. This work presents the most important and adequate techniques of analysis of environmental impact generated by nuclear activities starting from identification of the events causing negative effects upon environment (by using checking list, the matrices and the cause-effect diagram) and radiation dose determination up to the decision making process. To preserve environment integrity the human factor should be re-evaluated as well as its active participation in formation and settling of an real environmental culture

  3. Resource programs: Draft Environmental Impact Statement Resource Programs

    International Nuclear Information System (INIS)

    1992-03-01

    Every two years, Bonneville Power Administration (BPA) prepares a Resource Program which identifies the resource actions BPA will take to meet its obligation to serve the forecasted power requirements of its customers. The Resource Program's Environmental Impact Statement (RPEIS) is a programmatic environmental document which will support decisions made in several future Resource Programs. Environmental documents tiered to the EIS may be prepared on a site-specific basis. The RPEIS includes a description of the environmental effects and mitigation for the various resource types available in order to evaluate the trade-offs among them. It also assesses the environmental impacts of adding thirteen alternative combinations of resources to the existing power system. This report contains the appendices to the RPEIS

    Studies investigating diet-related environmental impacts have rarely considered the production method of the foods consumed. The objective of the present study, based on the NutriNet-Santé cohort, was to investigate the relationship between a provegetarian score and diet-related environmental impacts. We also evaluated potential effect modifications on the association between a provegetarian score and the environmental impacts of organic food consumption. Food intake and organic food consumption ratios were obtained from 34,442 French adults using a food frequency questionnaire, which included information on organic food consumption for each group. To characterize the overall structure of the diets, a provegetarian score was used to identify preferences for plant-based products as opposed to animal-based products. Moreover, three environmental indicators were used to assess diet-related environmental impacts: greenhouse gas (GHG) emissions, cumulative energy demand (CED), and land occupation. Environmental impacts were assessed using production life cycle assessment (LCA) at the farm level. Associations between provegetarian score quintiles, the level of organic food consumption, and environmental indicators were analyzed using ANCOVAs adjusted for energy, sex, and age. Participants with diets rich in plant-based foods (fifth quintile) were more likely to be older urban dwellers, to hold a higher degree in education, and to be characterized by an overall healthier lifestyle and diet. A higher provegetarian score was associated with lower environmental impacts (GHG emissions Q5vsQ1  = 838/1,664 kg CO 2eq /year, -49.6%, P  Organic food consumption was also an important modulator of the relationship between provegetarian dietary patterns and environmental impacts but only among participants with diets rich in plant-based products. Future field studies should endeavor to integrate all the components of a sustainable diet, i.e., both diet composition and

    The author evaluates the extent to which environmental impact assessment (EIA) as conceptualized by EIA systems is a gendered process. Through a discourse analysis of in-depth interviews with bureaucrats, technocrats, and activists involved with the Sardar Sarovar dam project in India, the author examines the practice of EIA in a Third World country. She uses a theoretical framework, informed by a theory of gender, to evaluate the interviews. In practice, EIA is marked by gender biases that ignore the gender-specific nature of impacts. Such biases distort the impact assessment process, making environmental sustainability difficult, if not impossible, to achieve

  9. An environmental impact measure for nuclear fuel cycle evaluation

    International Nuclear Information System (INIS)

    Ahn, Joonhong

    2004-01-01

    Review of the models and measures for repository performance assessment has revealed that dedicated measures for environmental impacts need to be developed for the purpose of nuclear-fuel-cycle evaluation from the viewpoint of environmental impact minimization. The present study proposes the total toxicity index of released radionuclides that have accumulated in the region exterior to the repository as an environmental impact measure. The measure is quantitatively evaluated by a radionuclide transport model that incorporates the effects of canister-array configuration and the initial mass loading in the waste canister. With the measure, it is demonstrated that the environmental impact of the repository can be effectively reduced by reduction of the initial mass loading and change in the canister-array configuration in the repository. Environmental impacts of the mill tailings and the depleted uranium are as important as those from the high-level radioactive wastes repository. For a fair comparison of various fuel cycles, the sum of these impacts should be compared. (author)

    Cardelli, J.A.; Clayton, G.C.

    1988-01-01

    In this paper, new high-quality extinction curves are presented for Theta-1 Ori A, C, and D, and Theta-2 Ori A and B, over the wavelength range 3300-6000 A. These are coupled with near-infrared and ultraviolet data to produce extinction curves from 0.12 to 3.5 microns. The Orion Nebula region is interesting in that most of the known processes of dust-grain growth, processing, and destruction may be operating nearly simultaneously in close proximity to one another. Each of these processes is considered with respect to the observed extinction curves and environmental conditions in the Orion Nebula and its associated molecular cloud. Plausible grain populations are fit to the observed extinction curves. A good fit to the average Theta Ori extinction curve can be obtained with: (1) a combination of larger than normal silicate grains produced through coagulation and accretion; (2) evaporation of volatile mantles; and (3) a reduction in the column density of small (smaller than 0.01 micron) grains responsible for the bump and far-ultraviolet extinction through differential acceleration due to radiation pressure and possible evaporation. It seems plausible to explain the observed peculiar extinction in the Orion Nebula simply by environmental effects on otherwise normal grains. 59 references

    Under certain conditions landscape topography which utilizes mine tailing reservoir construction using is likely to increase lateral recharge source regions, resulting in dramatic changes to the local hydrological dynamic field and recharge of downstream areas initiated by runoff, excretion state, elevated groundwater depth, shallow groundwater, rainfall direct communication, and thinning of the vadose zone. Corrosive leaching of topsoil over many years of exposure to chemical fertilizers and pesticides may result in their dissolution into the groundwater system, which may lead to excessive amounts of many harmful chemicals, therby affecting the physical and mental health of human residents and increase environmental vulnerability and risk associated with the water and soil. According to field survey data from Yujiakan, Qian'an City, and Hebei provinces, this paper analyzes the hydrogeological environmental mechanisms of areas adjacent to mine tailing reservoirs and establishes a conceptual model of the local groundwater system and the concentration-response function between NO3 - content in groundwater and the incidence of cancer in local residents.

    The high economic/industrial growth and the rapid increase in population, particularly in the developing world, is spurring a correspondingly fast growth in energy consumption. Energy in the form of electricity is a convenient source and a rapid increase in electricity generation is foreseen. However, at the same time it should also be kept in mind that economic progress is only one aspect of the overall social well being. It is essential to ensure that our efforts to generate the much needed electricity do not result in any severe detrimental impact on society or environment. The possible impacts of thermal, hydro and nuclear energy options are discussed in this paper. The useful role nuclear energy can play in enabling sustainable development is also briefly discussed.

    Purpose: To quantitatively evaluate the impact of interplay effect and plan robustness associated with intrafraction and residual interfraction prostate motion for pencil beam scanning proton therapy. Methods and Materials: Ten prostate cancer patients with weekly verification CTs underwent pencil beam scanning with the bilateral single-field uniform dose (SFUD) modality. A typical field had 10-15 energy layers and 500-1000 spots. According to their treatment logs, each layer delivery time was <1 s, with average time to change layers of approximately 8 s. Real-time intrafraction prostate motion was determined from our previously reported prospective study using Calypso beacon transponders. Prostate motion and beam delivering sequence of the worst-case scenario patient were synchronized to calculate the “true” dose received by the prostate. The intrafraction effect was examined by applying the worst-case scenario prostate motion on the planning CT, and the residual interfraction effect was examined on the basis of weekly CT scans. The resultant dose variation of target and critical structures was examined to evaluate the interplay effect. Results: The clinical target volume (CTV) coverage was degraded because of both effects. The CTV D{sub 99} (percentage dose to 99% of the CTV) varied up to 10% relative to the initial plan in individual fractions. However, over the entire course of treatment the total dose degradation of D{sub 99} was 2%-3%, with a standard deviation of <2%. Absolute differences between SFUD, intensity modulate proton therapy, and one-field-per-day SFUD plans were small. The intrafraction effect dominated over the residual interfraction effect for CTV coverage. Mean dose to the anterior rectal wall increased approximately 10% because of combined residual interfraction and intrafraction effects, the interfraction effect being dominant. Conclusions: Both intrafraction and residual interfraction prostate motion degrade CTV coverage within a

    Metal pollution of freshwater due to human activities is a major problem confronting most urban centres in developing countries. This study determined the extent to which aluminium in the residues from Morton Jaffray Water Works in Harare were affecting the water quality of Manyame River and Lake Manyame. The study also measured aluminium bioaccumulation in Nile Tilapia ( Oreochromis niloticus) which is of importance to the commercial fisheries industry in Zimbabwe. Depth integrated water, and sediment grab samples and adult fish were collected per site in January and March, 2010. A total of six sites were selected on the Manyame River and in Lake Manyame. The levels of Total Aluminium (Al) were determined in sediments, water and fish tissues (liver, kidney, gill and muscle). Total solids, total dissolved solids, conductivity, pH, dissolved oxygen and temperature were also determined in water and residues. The texture of the sediments was also assessed. Aluminium concentration in water ranged from 2.19 mg/L to 68.93 mg/L during both sampling campaigns surpassing permissible maximum concentration limits of 0.087 to 0.75 mg/L suggested by the Environmental Protection Agency and African Union. The site upstream of the discharge point of the residues always had the lowest levels though it was higher than acceptable levels indicated above, thus suggesting the existence of other sources of aluminium in the catchment besides Morton Jaffray Water Works. However, there was a 10-fold and 100-fold increase in levels of aluminium in water and sediments, respectively, at the site 100 m downstream of the discharge point on the Manyame River. Mean aluminium concentrations in water and sediments at this site averaged 68.93 ± 61.74 mg/L and 38.18 ± 21.54 mg/L in water and 103.79 ± 55.96 mg/L and 131.84 ± 16.48 mg/L in sediments in sampling campaigns 1 and 2, respectively. These levels were significantly higher than levels obtained from all the other sites during both sampling

    The first step of the expertise of the ten-year environmental assessment of Areva Nc was focused on the storage of mine residues of Bellezane and on the environmental impact of mine exploitation at the level of the Ritord watershed, these two aspects being appeared as a priority as regard to the different concerns and topical. The I.R.S.N. analysis consisted in checking that the impacts associated to the presence of residues are correctly controlled. The specificity of the storage system face to the water control rest on the capacity of water collect that have circulated at the residues contact and on their treatment before release. Concerning the exposure by emission in atmosphere, the characteristics of the roofing, particularly its thickness, allow to reduce significantly the residues contribution to the ambient gamma radiation and radon emission. The measured dose rate appear linked to the radiological content of deads themselves and rocks constituting the surrounding landscape. (N.C.)

  2. Impact of emerging environmental constraints on uranium supply

    2007-01-01

    Supply in the long term of uranium fuel is critical to the nuclear power industry. The general expectation at present is that future supply will be generated in a manner that meets current rigorous environmental standards. These standards, as defined by, for example, regulators, industry, international lending organizations and the IAEA, require minimal impact to the environment using a sustainable development approach that responsibly balances environmental, social and economic factors. The environmental factors that are associated with modern developments fall into two groupings: (1) conventional environmental issues, such as land use, effluent discharges and impact on biota; (2) emerging regulatory issues based upon evolving risk assessment approaches and determinations. It is the latter, in our experience, that poses the greatest risk to the long term uranium supply. Modern experience in Canada indicates that mines can be developed in a manner that satisfies conventional environmental assessment criteria. As such, there should be minimal environmental constraints to developing new supplies when they are developed using modern assessment and regulatory standards. However, when a strong precautionary, environmentally protectionist, view of development is utilized, to the exclusion of social and economic considerations, the perception of risk can become tied too closely to possible effects rather than actual impacts. This protectionist perception of risk to the environment has the potential to threaten the development of new projects through the imposition of prohibitively expensive requirements or restrictions with questionable environmental benefits, which in turn threatens the reliability of the long term global uranium supply. It is only through a balanced and systematic approach to sustainable development that both uranium supply and environmental protection will be assured. The paper briefly discusses the more conventional environmental and socioeconomic

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

    2017-04-01

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

  4. Quark masses: An environmental impact statement

    Jaffe, Robert L.; Jenkins, Alejandro; Kimchi, Itamar

    2009-01-01

    We investigate worlds that lie on a slice through the parameter space of the standard model over which quark masses vary. We allow as many as three quarks to participate in nuclei, while fixing the mass of the electron and the average mass of the lightest baryon flavor multiplet. We classify as congenial worlds that satisfy the environmental constraint that the quark masses allow for stable nuclei with charge one, six, and eight, making organic chemistry possible. Whether a congenial world actually produces observers capable of measuring those quark masses depends on a multitude of historical contingencies, beginning with primordial nucleosynthesis and including other astrophysical processes, which we do not explore. Such constraints may be independently superimposed on our results. Environmental constraints such as the ones we study may be combined with information about the a priori distribution of quark masses over the landscape of possible universes to determine whether the measured values of the quark masses are determined environmentally, but our analysis is independent of such an anthropic approach. We estimate baryon masses as functions of quark masses via first-order perturbation theory in flavor SU(3) breaking. We estimate nuclear masses as functions of the baryon masses using two separate tools: for a nucleus made of two baryon species, when possible we consider its analog in our world, a nucleus with a similar binding energy, up to Coulomb contributions. For heavy nuclei or nuclei made of more than two baryons, we develop a generalized Weizsaecker semiempirical mass formula, in which strong kinematic flavor symmetry violation is modeled by a degenerate Fermi gas . We check for the stability of nuclei against fission, strong particle emission (analogous to α decay), and weak nucleon emission. For two light quarks with charges 2/3 and -1/3 , we find a band of congeniality roughly 29 MeV wide in their mass difference, with our own world lying comfortably

    Renewable energy is a promising alternative to fossil fuel-based energy, but its development can require a complex set of environmental tradeoffs. A recent increase in solar energy systems, especially large, centralized installations, underscores the urgency of understanding their environmental interactions. Synthesizing literature across numerous disciplines, we review direct and indirect environmental impacts – both beneficial and adverse – of utility-scale solar energy (USSE) development, including impacts on biodiversity, land-use and land-cover change, soils, water resources, and human health. Additionally, we review feedbacks between USSE infrastructure and land-atmosphere interactions and the potential for USSE systems to mitigate climate change. Several characteristics and development strategies of USSE systems have low environmental impacts relative to other energy systems, including other renewables. We show opportunities to increase USSE environmental co-benefits, the permitting and regulatory constraints and opportunities of USSE, and highlight future research directions to better understand the nexus between USSE and the environment. Increasing the environmental compatibility of USSE systems will maximize the efficacy of this key renewable energy source in mitigating climatic and global environmental change.

    The National Aeronautics and Space Administration (NASA) Ames Research Center has developed the Airspace Concept Evaluation System (ACES), which is a fast-time simulation tool for evaluating Air Traffic Management (ATM) systems. This paper describes linking a capability to ACES which can analyze the environmental impact of proposed future ATM systems. This provides the ability to quickly evaluate metrics associated with environmental impacts of aviation for inclusion in multi-dimensional cost-benefit analysis of concepts for evolution of the National Airspace System (NAS) over the next several decades. The methodology used here may be summarized as follows: 1) Standard Federal Aviation Administration (FAA) noise and emissions-inventory models, the Noise Impact Routing System (NIRS) and the Emissions and Dispersion Modeling System (EDMS), respectively, are linked to ACES simulation outputs; 2) appropriate modifications are made to ACES outputs to incorporate all information needed by the environmental models (e.g., specific airframe and engine data); 3) noise and emissions calculations are performed for all traffic and airports in the study area for each of several scenarios, as simulated by ACES; and 4) impacts of future scenarios are compared to the current NAS baseline scenario. This paper also provides the results of initial end-to-end, proof-of-concept runs of the integrated ACES and environmental-modeling capability. These preliminary results demonstrate that if no growth is likely to be impeded by significant environmental impacts that could negatively affect communities throughout the nation.

  9. The likely adverse environmental impacts of renewable energy sources

    The global attention has always been focused on the adverse environmental impacts of conventional energy sources. In contrast nonconventional energy sources, particularly the renewable ones, have enjoyed a 'clean' image vis a vis environmental impacts. The only major exception to this general trend has been large hydropower projects; experience has taught us that they can be disastrous for the environment. The belief now is that minihydel and microhydel projects are harmless alternatives. But are renewable energy sources really as benign as is widely believed? The present essay addresses this question in the background of Lovin's classical paradigm, which had postulated the hard (malignant) and soft (benign) energy concepts in the first place. It critically evaluates the environmental impacts of major renewable energy sources. It then comes up with the broad conclusion that renewable energy sources are not the panacea they are popularly perceived to be; indeed in some cases their adverse environmental impacts can be as strongly negative as the impacts of conventional energy sources. The paper also dwells on the steps we need to take so that we can utilise renewable energy sources without facing environmental backlashes of the type we got from hydropower projects. (Author)

    Electric vehicle batteries use energy and generate environmental residuals when they are produced and recycled. This study estimates, for 4 selected battery types (advanced lead-acid, sodium-sulfur, nickel-cadmium, and nickel-metal hydride), the impacts of production and recycling of the materials used in electric vehicle batteries. These impacts are compared, with special attention to the locations of the emissions. It is found that the choice among batteries for electric vehicles involves tradeoffs among impacts. For example, although the nickel-cadmium and nickel-metal hydride batteries are similar, energy requirements for production of the cadmium electrodes may be higher than those for the metal hydride electrodes, but the latter may be more difficult to recycle

  11. Global carbon impacts of using forest harvest residues for district heating in Vermont

    International Nuclear Information System (INIS)

    McLain, H.A.

    1998-01-01

    Forests in Vermont are selectively logged periodically to generate wood products and useful energy. Carbon remains stored in the wood products during their lifetime and in fossil fuel displaced by using these products in place of energy-intensive products. Additional carbon is sequestered by new forest growth, and the forest inventory is sustained using this procedure. A significant portion of the harvest residue can be used as biofuel in central plants to generate electricity and thermal energy, which also displaces the use of fossil fuels. The impact of this action on the global carbon balance was analyzed using a model derived from the Graz/Oak Ridge Carbon Accounting Model (GORCAM). The analysis showed that when forests are harvested only to manufacture wood products, more than 100 years are required to match the sequestered carbon present if the forest is left undisturbed. If part of the harvest residue is collected and used as biofuel in place of oil or natural gas, it is possible to reduce this time to about 90 years, but it is usually longer. Given that harvesting the forest for products will continue, carbon emission benefits relative to this practice can start within 10 to 70 years if part of the harvest residue is used as biofuel. This time is usually higher for electric generation plants, but it can be reduced substantially by converting to cogeneration operation. Cogeneration makes possible a ratio of carbon emission reduction for district heating to carbon emission increase for electricity generation in the range of 3 to 5. Additional sequestering benefits can be realized by using discarded wood products as biofuels

  12. Not carbon neutral: Assessing the net emissions impact of residues burned for bioenergy

    Climate mitigation requires emissions to peak then decline within two decades, but many mitigation models include 100 EJ or more of bioenergy, ignoring emissions from biomass oxidation. Treatment of bioenergy as ‘low carbon’ or carbon neutral often assumes fuels are agricultural or forestry residues that will decompose and emit CO2 if not burned for energy. However, for ‘low carbon’ assumptions about residues to be reasonable, two conditions must be met: biomass must genuinely be material left over from some other process; and cumulative net emissions, the additional CO2 emitted by burning biomass compared to its alternative fate, must be low or negligible in a timeframe meaningful for climate mitigation. This study assesses biomass use and net emissions from the US bioenergy and wood pellet manufacturing sectors. It defines the ratio of cumulative net emissions to combustion, manufacturing and transport emissions as the net emissions impact (NEI), and evaluates the NEI at year 10 and beyond for a variety of scenarios. The analysis indicates the US industrial bioenergy sector mostly burns black liquor and has an NEI of 20% at year 10, while the NEI for plants burning forest residues ranges from 41%-95%. Wood pellets have a NEI of 55%-79% at year 10, with net CO2 emissions of 14-20 tonnes for every tonne of pellets; by year 40, the NEI is 26%-54%. Net emissions may be ten times higher at year 40 if whole trees are harvested for feedstock. Projected global pellet use would generate around 1% of world bioenergy with cumulative net emissions of 2 Gt of CO2 by 2050. Using the NEI to weight biogenic CO2 for inclusion in carbon trading programs and to qualify bioenergy for renewable energy subsidies would reduce emissions more effectively than the current assumption of carbon neutrality.

  13. Savannah River Site Waste Management Final Environmental Impact Statement Addendum

    International Nuclear Information System (INIS)

    1995-07-01

    The purpose of this environmental impact statement is to help DOE decide how to manage over the next 30 years liquid high-level radioactive, low-level radioactive, mixed, hazardous, and transuranic wastes generated during 40 years of past operations and on-going activities (including management of wastes received from offsite) at Savannah River Site (SRS) in southwestern South Carolina. The wastes are currently stored at SRS. DOE seeks to dispose of the wastes in a cost-effective manner that protects human health and the environment. In this document, DOE assesses the cumulative environmental impacts of storing, treating, and disposing of the wastes, examines the impacts of alternatives, and identifies measures available to reduce adverse impacts. Evaluations of impacts on water quality, air quality, ecological systems, land use, geologic resources, cultural resources, socio-economic, and the health and safety of onsite workers and the public are included in the assessment

    Larsson, C.M.

    2002-01-01

    The overall aim of the FASSET project is to develop a framework within which assessment models, relevant to the impact of ionising radiation on the environment, can be applied and results analysed for European ecosystems. Complete documentation on the FASSET project can be found on the FASSET's web-site (www.fasset.org). This paper describes the current state of the project, based on the project's first Annual Report. Seven European ecosystems are considered; four terrestrial (natural forests, semi-natural pastures, agricultural ecosystems and wetlands) and three aquatic (marine, brackish and freshwater). In FASSET Deliverable 1 a list of candidate generic reference organisms has been drawn up on the basis of expert judgement of exposure situations in the selected ecosystems. They serve as a starting points for development of dosimetric models, and for pooling available information on ecological relevance and biological effects. Further analysis of the candidate reference organisms is performed to justify their choice and assess their applicability in different situations, taking into account modelling of radionuclide transfer, estimates of internal and external dose rates, ecological significance and biological effects. Four general 'umbrella' radiation effects on biota are considered that, when manifested in an individual, may have an impact at population level or at higher levels of the organisational hierarchy. The four 'umbrellas' are: morbidity (fitness or well-being), mortality (death directly attributable to radiation), reproductive success (changed number of offspring) and scorable cytogenetic effects (molecular actions, aberrations). A database is being assembled, compiling dose and dose rates data from the literature for a number of organism categories for each of these four umbrella effects. The database also considers the suitability of data to derive the relative biological efficiency (RBE) for different types of radiation. The work from the three

    Full Text Available The analysis of gunshot residue (GSR has played an integral role within the legal system in relation to shooting cases. With a characteristic elemental composition of lead, antimony, barium, and a typically discriminative spheroidal morphology, the presence and distribution of GSR can aid in firearm investigations. In this experiment, three shots of low velocity rim-fire ammunition were fired over polished silicon collection substrates placed at six intervals over a 100 cm range. The samples were analysed using a Field Emission Gun Scanning Electron Microscope (FEG-SEM in conjunction with an X-flash Energy Dispersive X-ray (EDX detector, allowing for GSR particle analyses of composition and structure at the sub-micron level. The results of this experiment indicate that although classic spheroidal particles are present consistently throughout the entire range of samples their sizes vary significantly, and at certain distances from the firearm particles with an irregular morphology were discerned, forming “impact-disrupted” GSR particles, henceforth colloquially referred to as “splats”. Upon further analysis, trends with regards to the formation of these splat particles were distinguished. An increase in splat frequency was observed starting at 10 cm from the firearm, with 147 mm−2 splat density, reaching a maximal flux at 40 cm (451 mm−2, followed by a gradual decrease to the maximum range sampled. Moreover, the structural morphology of the splats changes throughout the sampling range. At the distances closest to the firearm, molten-looking particles were formed, demonstrating the metallic residues were in a liquid state when their flight path was disrupted. However, at increased distances-primarily where the discharge plume was at maximum dispersion and moving away from the firearm, the residues have had time to cool in-fight resulting in semi-congealed and solid particles that subsequently disrupted upon impact, forming more

    Power Quality (PQ) is becoming of great concern to consumers and utilities. Utility companies, equipment manufacturers and electric power customers are the main three parameters who have great interests and growing concern with PQ. Alexandria Electricity Distribution Company (AEDC) is one of the utility company who try to enhance power quality through decreasing disruptions and interruptions which occur by improving the reliability since reliability coupled with power quality and customer service are key components in delivering an effective electricity support to customers which consequently affect the global environment. One strategic solution which has been developed in recent years by AEDC is the Distribution Management System (DMS) that provide remote monitoring of currents, voltages and switch positions of various remote circuit components (direct measurements), control operation and improving the quality of customer service through the reduction of outage time and the monthly detection of reliability indices: System Average Interruption Frequency Index (SAIFI) , System Average Interruption Duration Index (SAIDI), Customer Average Interruption Duration Index (CAIDT) in order To save energy hoping to decrease the global wanning effect and greenhouse gas effect and acid rain phenomena. This paper will cover the effect of DMS on the reliability indices: SAIFI, SAIDI, CAIDI during the last few years and their improvement due to the accuracy of information taken by DMS. In addition, it will discuss the minimization of power losses and their environmental effects on the global warming and greenhouse gas phenomena

  18. Environmental protection and cost/visual impacts

    Paris, L.

    1993-01-01

    A hastily thought out section (article 5) of a recent Italian decree intended for the protection of the environment against the effects of electric and magnetic fields will wind up in fact creating a large waste of resources and will perhaps even damage the environment it originally was intended to defend The paper first points the efficacy of the European Communities/ICRP (International Commission on Radiation Protection) approaches taken towards the planning of overhead power transmission line safety guidelines in which engineering feasibility and cost considerations were balanced with safety requirements on a global scale. It then points out that, whereas the Italian decree wisely made use of the EC guidelines, it also added other guidelines which simply specified minimum distances from living/working areas and the nearest power cable in function of the voltage it carries. This philosophy is neither cost effective nor environmentally sound because it doesn't take into account specific engineering and aesthetic aspects related to the geometric configuration of transmission towers, the correlation between cable spacing and generation of electromagnetic radiation, and the technical/cost feasibility of all possible remedial actions (e.g., tower retrofitting with compact overhead configurations)

  19. Environmental impact of low concentrated wastes

    Barescut, J.C.

    1998-01-01

    A means to reduce the impact of a waste landfill is to limit its content so that after a reasonably short time, its radioactivity does not significantly exceed the natural level. For this means to be effective, it must be demonstrated that the system will not, in the long run, spontaneously evolve towards local sports of higher concentration. This process would require considerable converging migrations that would offer many opportunities for mixing and thus be inconsistent with concentration. Moreover, concentration is an energy-demanding process that will be limited by the availability of energy, especially in chemical form. For these reasons, it is wise to avoid placing a landfill where energy is likely to be more readily available than on the average. It is also advisable to avoid artificial protections, if their future evolution is not fully understood, since they necessarily contain an excess of energy relative to the undisturbed natural state.

  20. Recommendations for the Preparation of Environmental Assessments and Environmental Impact Statements, 2nd edition

    Energy Technology Data Exchange (ETDEWEB)

    None, None

    2004-12-01

    This document provides recommendations for the Department of Energy’s (DOE’s) preparation of environmental assessments and environmental impact statements under the National Environmental Policy Act of 1969 (NEPA). The Office of NEPA Policy and Compliance prepared these recommendations in consultation with the Office of the Assistant General Counsel for Environment and following coordination with the DOE NEPA Community. The recommendations should materially aid those responsible for preparing and reviewing NEPA documents to focus on significant environmental issues, adequately analyze environmental impacts, and effectively present the analysis to decisionmakers and the public. The recommendations are not all-encompassing, however; preparers must apply independent judgment to determine the appropriate scope and analytical requirements of NEPA for each proposal. These recommendations do not constitute legal requirements, but are intended to enhance compliance with existing NEPA regulations (40 CFR Parts 1500-1508, 10 CFR Part 1021).

  1. Environmental impacts on soil and groundwater at airports: origin, contaminants of concern and environmental risks.

    Science.gov (United States)

    Nunes, L M; Zhu, Y-G; Stigter, T Y; Monteiro, J P; Teixeira, M R

    2011-11-01

    Environmental impacts of airports are similar to those of many industries, though their operations expand over a very large area. Most international impact assessment studies and environmental management programmes have been giving less focus on the impacts to soil and groundwater than desirable. This may be the result of the large attention given to air and noise pollution, relegating other environmental descriptors to a second role, even when the first are comparatively less relevant. One reason that contributes to such "biased" evaluation is the lack of systematic information about impacts to soil and groundwater from airport activities, something the present study intends to help correct. Results presented here include the review of over seven hundred documents and online databases, with the objective of obtaining the following information to support environmental studies: (i) which operations are responsible for chemical releases?; (ii) where are these releases located?; (iii) which contaminants of concern are released?; (iv) what are the associated environmental risks? Results showed that the main impacts occur as a result of fuel storage, stormwater runoff and drainage systems, fuel hydrant systems, fuel transport and refuelling, atmospheric deposition, rescue and fire fighting training areas, winter operations, electrical substations, storage of chemical products by airport owners or tenants, and maintenance of green areas. A new method for ranking environmental risks of organic substances, based on chemical properties, is proposed and applied. Results show that the contaminants with the highest risks are the perfluorochemicals, benzene, trichloroethylene and CCl(4). The obtained information provides a basis for establishing the planning and checking phases of environmental management systems, and may also help in the best design of pollution prevention measures in order to avoid or reduce significant environmental impacts from airports.

    2013-12-01

    There is a long history of land use and land cover (LULC) change for agriculture in the Midwest USA. This change has been in response to many factors, including advances in technology, improved fertilizer and pest management, and changing market forces. The change of LULC leads to a variety of impacts on near surface dynamics such as the water budget and watershed hydrology, local weather conditions and future climate trends, carbon balance, nutrient cycling and water quality, and ecosystem goods and services. Environmental consequences of LULC change are distributed unevenly due to the heterogeneity of land surface characteristics; therefore, it is critical to assess the impacts of LULC change regionally. We used Agro-IBIS, a dynamic global vegetation model, to evaluate the historical effects of LULC change in the Midwest USA with a focus on water, energy, and carbon budgets as well as biomass production for 2007-2012. We also predicted LULC effects as a consequence of meeting projected bioenergy production demand from corn grain ethanol in 2020. Scenarios include expansion of land for corn production as well as the removal of different amounts of crop residue from fields. Simulation results show that evapotranspiration, soil carbon, and net ecosystem productivity will increase in the future due to the corn expansion without corn residue removal. The effects of removing corn residue on soil carbon and net ecosystem productivity vary with the removal rates. Future work will evaluate additional scenarios and will contribute to scenario development.

    A clean environment is essential for human health because the interaction between the environment and human health shows the complexity. Air pollution, less water quality, noise etc directly affects the health. Climate change, depletion of ozone layer, loss of biodiversity and degradation of land can also affect human health. Most of the modern technologies produce radiations in the environment having both beneficial and harmful effects through radioactive material. Natural radioactive sources include Cosmic radiation comes from the sun and outer space is absorbed by the atmosphere, a small amount reaches the earth's surface to which we are exposed. The exposure to this type of radiation is higher for people living above sea level. Radon is produced through the decay of uranium and thorium that are found naturally in the earth's crust. Primordial and terrestrial radiation are present in rocks and soils and occur when naturally radioactive isotopes of uranium, thorium and potassium decay within the earth's crust. Artificial (or man-made) radioactive sources include Fallout radiation, which results from past atmospheric nuclear bomb tests (1950s and 1960s many test explosions). Each environmental change, whether occurring as a natural phenomenon or through human intervention, changes the ecological balance and context within which disease hosts or vectors and parasites breed, develop, transmit disease. Today, radiation is a common used in medicine to diagnose illnesses, research to treat diseases and industry to generate electricity in nuclear power reactors. Radiation is energy that moves through space or matter at a very high speed. This energy can be in the form of particles, such as alpha or beta particles, which are emitted from radioisotopes. Radioactive Material is material that contains an unstable atomic nucleus releases radiation in the process of changing to a stable form. There are two types of health effects from radiation - threshold and non threshold

    Morvell, G.

    2002-01-01

    Federal environmental impact assessment legislation has existed in Australia since 1974. A number of uranium mines have been developed in this time, utilizing a range of mining techniques, including opencut, underground and in-situ leach. Projects have also been undertaken in a variety of geographical areas requiring consideration of diverse biodiversity, cultural heritage and social impact issues. Assessment of uranium mining proposals in Australia is also conducted in a climate of political opposition from a cross section of the Australian community. This paper outlines some of the key issues that arose during recent assessments and which provide a lead to the role of environmental impact assessment in environmental policy development. Issues are also relevant to recent assessments on a replacement nuclear reactor, shipments of waste for reprocessing and proposed assessments on proposals for low and intermediate level nuclear waste facilities.

    2017-06-01

    Full Text Available Sand is an indispensable natural resource for any society. Despite society’s increasing dependence on sand, there are major challenges that this industry needs to deal with: limited sand resources, illegal mining, and environmental impact of sand mining. The purpose of this paper is twofold: to present an overview of the sand market, highlighting the main trends and actors for production, export and import, and to review the main environmental impacts associated with sand exploitation process. Based on these findings, we recommend different measures to be followed to reduce negative impacts. Sand mining should be done in a way that limits environmental damage during exploitation and restores the land after mining operations are completed.

    How to assess environmental impact is one of the keys in land use planning. This article described in detail the concepts of activities, impact zones, functions, and sensitivities, as well as the development of STEPP (strategic tool for integrating environmental aspects in planning procedures) based on Avenue, the secondary developing language of ArcView GIS. The system makes it convenient for planning practitioners exchanging information, and can spatially, visually and quantitatively describe environmental impact and its change. In this study, the urban-rural combination area located between EDE and Veenendaal of The Netherlands was taken as case, and the results indicated that the environment was incorporated well in the planning procedure based on the concepts, and could also demonstrate the effects of planning measures on environment spatially, explicitly, and in real-time, facilitating the participation of planning practitioners and decision-making. Some proposals of how to promote STEEP application in China were suggested.

    The increase of the share of renewable energy in Portugal can be met from different sources, of which forest biomass residues (FBR) can play a main role. Taking into account the demand for information about the strategy of FBR to energy, and its implications on the Portuguese climate policy, the impact of energy conversion of FBR on air quality is evaluated. Three emission scenarios were defined and a numerical air quality model was selected to perform this evaluation. The results reveal that the biomass thermal plants contribute to an increment of the pollutant concentrations in the atmosphere, however restricted to the surrounding areas of the thermal plants, and most significant for NO₂ and O₃.

    In this study a complementary modeling and experimental approach was used to explore how growth controls the NADPH generation and availability, and the resulting impact on PHB (polyhydroxybutyrate) yields and kinetics. The results show that the anabolic demand allowed the NADPH production through the Entner-Doudoroff (ED) pathway, leading to a high maximal theoretical PHB production yield of 0.89 C mole C mole(-1); whereas without biomass production, NADPH regeneration is only possible via the isocitrate dehydrogenase leading to a theoretical yield of 0.67 C mole C mole(-1). Furthermore, the maximum specific rate of NADPH produced at maximal growth rate (to fulfil biomass requirement) was found to be the maximum set in every conditions, which by consequence determines the maximal PHB production rate. These results imply that sustaining a controlled residual growth improves the PHB specific production rate without altering production yield. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Organizations are submitted to social pressure towards making decisions for the sake of more environmental responsibility. These organizations respond by adopting managing strategies, and by developing environmental policies whose results must be demonstrated to stakeholders. In this scenario, this study aims at analyzing the characteristics of environmental information presented in management reports, in explanatory notes and in balance sheets produced by companies with a high environmental impact listed on BM&FBovespa, identifying possible isomorphic behaviors. In order to reach that goal, a qualitative research was conducted with an analysis of management reports, balance sheets and explanatory notes for the years 2011, 2012 and 2013 by 44 companies. Results provide evidence that companies present similar behavior concerning environmental issues. The management reports contain the largest amount of information related to the environment, the most highlighted categories were Environmental Policies, Product Impact, Processes and Other environmental information. Besides that, the segments that disclosed the most environmental information were Paper and Cellulose, Metalworking, Exploration and Refinement whereas the largest companies, evaluated by total assets, disclosed more environmental information.

    Full Text Available Solutions in the field of ecological architecture appear more and more often in Poland. There are two approaches to eco-design: high-tech and low-tech. High-tech focuses on the use of the latest technological solvings. These means are often used in newly designed commercial buildings, such as the first Polish office building which uses passive technology, built in Katowice, in Euro-Centrum Science and Technology Park. It is intended especially for companies focusing on energy observance issues. Low-tech is usually used in small-scale buildings (for example a cottage in Jartypory village, and is focused on the use of inexpensive, traditional technologies and the daily conscious management of natural resources. Thinking about the impact on the environment and principles of sustainable development is also present in urban planning. In Siewierz, near Katowice, Poland’s first eco-village is being built, with full infrastructure, high-quality residential buildings, shops, offices and hotels. The range of applied solutions will allow residents for the economical exploitation of these buildings.

  18. 3.6 Environmental impacts: transport

    International Nuclear Information System (INIS)

    2004-01-01

    Transport is one of the main causes of air and noise pollution, is a drain on energy and a significant contributor to the greenhouse effect. Despite some improvement in vehicle and fuel technology, it has been impossible to reduce these negative side effects to any significant degree over the past few years. Measures for reducing these subsequent negative effects on the environment deal with two key objectives of the Austrian Sustainable Strategy (Oesterreichische Nachhaltigkeitsstrategie): 'shaping sustainable mobility' focuses primarily on changes in 'mobility pressures' caused by the spatial separation of functions (housing, work and leisure) and 'optimizing the transport systems' focuses on innovations, technology and infrastructure designed to promote environment-friendly, resource-friendly, energy-efficient and safe forms of transport. Under these considerations, different aspects of the Austrian transport such as situation and trends, vehicle technology, fuels, impact on the environment (energy consumption, pollutants emissions as CO 2 , NO x , HC (hydrocarbons), CO, N 2 O, NH 3 , SO 2 and particulates) during 2001-2003 are discussed in this subchapter.

    2006-01-01

    Hydrogen-based energy systems appear to be an attractive proposition in providing a future replacement for the current fossil-fuel based energy systems. Hydrogen is an important, though little studied, trace component of the atmosphere. It is present at the mixing ratio of about 510 ppb currently and has important man-made and natural sources. Because hydrogen reacts with tropospheric hydroxyl radicals, emissions of hydrogen to the atmosphere perturb the distributions of methane and ozone, the second and third most important greenhouse gases after carbon dioxide. Hydrogen is therefore an indirect greenhouse gas with a global warming potential GWP of 5.8 over a 100-year time horizon. A future hydrogen economy would therefore have greenhouse consequences and would not be free from climate perturbations. If a global hydrogen economy replaced the current fossil fuel-based energy system and exhibited a leakage rate of 1%, then it would produce a climate impact of 0.6% of the current fossil fuel based system. Careful attention must be given to reduce to a minimum the leakage of hydrogen from the synthesis, storage and use of hydrogen in a future global hydrogen economy if the full climate benefits are to be realised.

    BNFL's strategy for the management of aerial and marine radioactive effluents arising from THORP was first formally stated at the Windscale Inquiry in 1977. In summary, the design intent was that: radiation exposure of members of the general public, arising from discharges from THORP and associated facilities, should be 'As Low as is Reasonably Practicable' (ALARP); no member of the most highly exposed (critical) group(s) should receive an annual committed effective dose equivalent in excess of 50μSv from either aerial or marine discharge routes; that by the time THORP was operational, the sum total of annual exposure (CEDE) arising from operations on the whole of the Sellafield site (including those arising from the continuing effect of historical discharges) should not exceed 500μSv p.a. This paper examines the discharges predicted and their projected impact against the originally broad design intent, and specifically explores whether any further effluent discharge (and therefore dose) reduction, was practicable and indeed justifiable. As background, a brief summary of the THORP process is given, together with detail of the aerial effluent treatment and ventilation systems. (author)
