Developing environmental quality standards for various pesticides and priority pollutants for French freshwaters 总被引:2,自引:0,他引:2

The French Ministry of the Environment and Water Agencies have derived environmental quality standards following the existing French framework called SEQ-Eau, for 28 pesticides and seven priority substances listed in the Water Framework Directive. Like other existing frameworks, SEQ-Eau relies upon the use of standard toxicity test results and assessment factors. This approach made it possible to derive the desired quality standards, but due to the lack of chronic toxicity data many of the standards are only provisional. In addition, emerging issues such as endocrine disruption should be taken into account in this framework. Depending on the available data, more flexible derivation approaches, such as the statistical distribution of NOECs, are recommended for future versions of SEQ-Eau. A comparison is made using SEQ-Eau and the methodology currently being discussed in Europe to develop environmental quality standards, showing that the European approach is more conservative. Conversely, the proposed approach under the Water Framework Directive does not cover the entire range of required quality classes. 相似文献

Rice is a widely grown crop in Asia. China (30%) and India (21%) contribute to about half of the world's total rice production. In this study, three major rice-producing countries in Asia are considered, India, Thailand and the Philippines (the later two contributing 4% and 2% of the world's rice production). Rice straw is one of the main field based residues produced along with this commodity and its applications vary widely in the region. Although rice production practises vary from one country to another, open burning of straw is a common practice in these countries.In this study, an approach was followed aiming at (a) determining the quantity of rice straw being subject to open field burning in those countries, (b) congregating pollutant specific emissions factors for rice straw burning, and (c) quantifying the resulting air pollutant emissions. Uncertainties in the results obtained as compared to a global approach are also discussed. 相似文献

Solid waste disposal in Sri Lanka has been assessed using environmental, economic, and social indicators, based on a life cycle approach. The existing situation of open dumping in Sri Lanka was compared with that of a sanitary landfill with gas recovery, since the latter is anticipated to constitute an initial step towards sustainable development. The results revealed the extent to which sanitary landfills with gas recovery systems could contribute to reducing environmental impacts such as global warming potential, acidification potential, and eutrophication potential. Assessment of life cycle cost and damage to human health also showed results in favour of sanitary landfills with gas recovery system. The results obtained quantify the sustainability benefits of the proposed option for solid waste management, and can be useful for justifying policy measures that encourage the replacement of open dumping with sanitary landfills. 相似文献

Large (to >1 m), diurnally active tiger snakes (Notechis scutatus) are abundant on Carnac Island, near the coast of Western Australia. Our behavioural and mark-recapture studies provide the
first ecological data on this population, and reveal a surprising phenomenon. Many adult tiger snakes have had their eyes
destroyed, apparently during nest defence, by silver gulls (Larus novaehollandiae). This loss of vision did not reduce the snakes' body condition (mass relative to length), or their rates of growth or survival
(measured over a 12-month period). Blind male snakes trail-followed females, and mated successfully. Thus, destruction of
a major sensory modality had no detectable effect on these predators. This result is strongly counter-intuitive, but mirrors
an earlier report of congenital blindness (without ill-effects) in American viperid snakes. Similarities between the two systems
(island populations, highly venomous snakes, reliance on sessile prey) clarify the circumstances under which the loss of vision
does not reduce an organism's viability. These natural experiments support Gans' hypothesis of “momentarily excessive construction”
in that the snakes possess a complex organ system that they do not actually require for successful feeding, survival or reproduction.
