近年来,随着我国经济的发展,次级河流突发性水污染事件频繁发生,对生态环境及居民生活造成了严重的影响。次级河流突发性水污染事件发生后,为减少污染造成的损失和影响,保证受损的环境资源得到恢复和补偿,不仅要立即采取行之有效的应急处置措施,而且应当积极开展环境损害鉴定评估工作,全面追究污染者的环境责任。根据次级河流本身的特点,结合各省市在环境应急处置过程中的具体做法,建立了一套应对突发性次级河流水污染事件的应急处置工作程序;阐述了环境损害鉴定评估的必要性、工作方法和技术路线,同时从受损环境资源的确认、污染源和污染物的识别以及暴露途径的建立3个方面构建了开展次级河流突发性水污染事件环境损害鉴定评估工作的因果关系链条,对实际开展相关工作具有重要意义。 相似文献

Enzyme-immunoassay techniques for the detection of atrazine in water samples: Evaluation of a commercial tube based assay 总被引:1,自引:0,他引:1
Environmental immunoassays can help lower the operating costs and improve the effectiveness of residue laboratories. The present study assesses the ability of a commercially available enzyme immunoassay (EIA) to detect triazine herbicides in water. The tube based EIA could detect atrazine in lake and river water with detection limits of 62 pg/mL and 180 pg/mL respectively. The assay's ability to quantify atrazine in a set of 124 water samples taken from many parts of Canada was compared with a reference method that used gas chromatographic separation combined with a nitrogen phosphorous detector (GC-NPD) (R=0.919). A 71 % reduction in analytical load was achieved at a threshold concentration of 1 ng/mL. There were 2.4 % false negative and 0.8 % false positive results associated with that load reduction. The variability of the assay control parameters was generally within two standard deviations of the mean response for 65 assays. The EIA for atrazine is recommended for use as a screening technique and as an inexpensive way to monitor triazine levels in waters that are known to be contaminated with those herbicides. 相似文献

Abstract The use of agrochemicals like crop protecting agents, veterinary disinfectants, and wood preservatives may result in (un)intentional exposure of the environment, animals and man. This paper deals with current testing strategies to assess the potential health risks for humans exposed to these chemicals during production or application or via consumption of foods containing pesticide residues. Principles and procedures for safety assessment of pesticide residues in food as developed by WHO/FAO are described. Different types of toxicity studies in mammalian test animal species are discussed and a strategy is outlined in order to characterize the toxicity profile of a compound and the relationship between applied doses and adverse effects. Safety testing of agrochemicals should be carried out in relation to its intended use, and in particular attention will be paid to toxicity testing of residues of pesticides in food. Extrapolation of results from animal studies to humans and the use of safety factors is discussed. Besides the use of animal protocol studies for safety testing of agrochemicals, the potential use of in‐vitro models derived from organs and tissues of animals is discussed. Data on the in‐vitro metabolism of thiabendazole, aldicarb and alachlor are discussed in order to demonstrate that such data may complement or partly substitute whole animal experimentation. Principles and procedures for safety testing of residues of agrochemicals in food as applied during the last three decades, constitute a ‘safety‐first’ approach, providing sufficient safety margins for the consumer of foods which may contain low levels of residues of agrochemicals. 相似文献
