The environmental specimen banking program (ESB) of the Federal Republic of Germany implies a collection of specimens from representative areas of Germany, stored under stable conditions for deferred analysis. It is an important part of the ecological assessment program. The ecological concept is presented as the frame of the entire ESB program. It is based on the selection of representative sampling areas and specimens. Standard operating procedures (SOP’s) for sampling and characterization of specimens, as well as sampling designs specific to the areas, are presented as further important parts of the quality assurance system in relation to the correct sampling of specimens.  相似文献

Although the use of tissue concentrations (residues) of chemical contaminants as the dose metric to characterize chemical toxicity to aquatic organisms has been gaining acceptance over the past 20 years, tissue concentrations are less commonly used in water quality management and have yet to be formally adopted as benchmarks or environmental quality standards (EQS). This synthesis paper addresses advantages and disadvantages for the development and application of tissue-based EQS as an alternative and supplement to exposure-based EQS determined with water and sediment concentration data. Tissue-based EQS can be readily developed in parallel with conventional toxicity tests, and achieved by quantification of chemical concentrations in tissue alongside traditional concentration-response toxicity testing. Tissue-residue toxicity metrics can be used as benchmarks for screening and monitoring water and sediment quality, to derive equivalent water or sediment EQS, and for ecological risk assessments and weight of evidence approaches for assessing ecosystem impairment. Tissue-based toxicity metrics and associated EQS provide several advantages; however, there are some limitations to consider and key knowledge gaps to fill.  相似文献

The author describes present environmental conditions in Azerbaijan in relation to the Soviet legacy and measures taken since independence. Environmental projects have been financed largely by international organizations and foreign companies. The most serious problems are contaminants in the Caspian Sea; air, water, and soil pollution in Sumgait; illegal fishing; poor quality of drinking water; cutting of forests for fuel and pasture; overgrazing; and soil erosion and salinization. Progress in developing an environmental conscience, necessary for sustained protection of the environment, will depend most importantly on environmental education, growth of democratic institutions and attitudes that encourage both governmental and citizen responsibility for the environment, and economic development that produces a substantial middle class. Positive advances include a Constitution and laws that require protection of the environment, and individuals who speak out for environmental care. Negative factors include poverty and the present government's low priority for environmental protection.  相似文献

全氟辛烷磺化物及其环境问题   总被引:4,自引:0,他引:4  
全氟辛烷磺化物(PFOS)是全氟化合物(PFCS)的代表物,以PFOS为原料可以生产许多用途广泛的PFOS相关物质,并且在环境中都能降解生成PFOS.PFOS是一种新型的持久性有机污染物(POPs),已经成为环境科学研究的热点问题.主要从物理化学性质、毒性、环境及人体暴露水平等方面对PFOS进行了综述,并将中国有关的现有数据与其他国家进行了比较.研究表明,中国人体、水体均存在着大范围的以PFOS为主的PFCS污染.  相似文献
