我国地下水环境优先控制有机污染物的筛选

针对当前我国地下水有机污染现状和监测评价的需求，借鉴国内外研究经验，以污染物的急性毒性、生殖毒性、致癌性、内分泌干扰性、环境持久性、生物累积性、迁移性和出现频率为评价指标，采用层次分析法(AHP)结合加权评分法，对地下水优先污染物进行了定量筛选。提出了地下水环境优先控制的共16类85种有机污染物名单，包括卤代烃类16种、多环芳烃13种、农药类20种、酚类7种、氯代苯6种、苯系物6种、硝基苯类3种、酯类3种、醛类2种、苯胺类2种、亚硝胺2种以及二氯乙酸、丙烯腈、多氯联苯、甲基叔丁基醚和丙烯酰胺等。根据有机污染物对环境的危害，筛选着重考虑环境分布广、浓度高及危害较大的物质。

Screening of Priority Organic Pollutants in Groundwater of China

The priority organic pollutants in groundwater were screened based on foreign and domestic research experience to meet the demand of monitoring and assessment in groundwater pollution of China. Acute toxicity, reproductive toxicity, carcinogenicity, endocrine disrupting activity, persistence, bioaccumulation, migration and occurrence frequency of pollutants were selected as assessment indicators. Analytic Hierarchy Process combined with Weighted Mark Method was used in quantitative screening of priority organic pollutants in groundwater. Sixteen categories including 85 organic pollutants were tentatively selected on the priority pollutants list, which contains 16 kinds of halogenated hydrocarbons, 13 kinds of polycyclic aromatic hydrocarbons, 20 kinds of pesticides and herbicide, 7 kinds of phenols, six kinds of chlorinated benzene, 6 kinds of BTEX, three kinds of nitrobenzene, 3 kinds of esters, 2 kinds of aldehydes, 2 kinds of anilines, 2 kinds of nitrosamines and dichloroacetic acid, acrylonitrile, PCBs, MTBE and acrylamide. The screening focused on considering the organic substances that widely distributed in the environment with high concentration and harmfulness to the environment.
