欧盟水框架指令优先污染物筛选方法的应用

利用欧盟水框架指令(EU WFD)方法筛选优先污染物,得到适用于我国的水环境优先控制污染物清单。检索了包括中国、美国、欧盟、日本等国家和地区的水质标准和污染物清单,对这些清单污染物进行初筛选,得到449种污染物为我国登记在用的污染物,在此基础上运用改进的WFD优先污染物筛选方法对这些污染物进行计分筛选,并按照其半致命毒性LD50排序,得到包含19种污染物的水环境优先控制污染物排序清单。结果表明,WFD优先污染物筛选方法能较全面的筛选出环境危害大的污染物,根据我国实际情况,对WFD现有污染物清单做出补充与筛选后,适合作为水环境优控污染物筛选的方法。

THE APPLICATION OF A PRIORITIZATION EXERCISE FOR THE EUROPEAN WATER FRAMEWORK DIRECTIVE

A list of priority control pollutants was obtained by using the improved model-based prioritization exercise for the EU Water Framework Directive ( EU WFD) ． Retrieved pollutants lists and water quality standards in the United States， European Union，Japan and other countries and regions，by preliminary analyzing and screening substances from these lists， 449 substances were registered and being used in our country． These substances were given scores by the improved modelbased prioritization exercise for the EU WFD，then were ranked according to their semi lethal toxity，in the end，a list of 19 substances were classified as sorting list of environmental priority substances． The results showed that，after supplement and screening the existing list of pollutants for WFD combined with Chinese actual situation，the method was suitable as a screening method for environmental priority pollutants，it can comprehensively screen substances with serious environmental hazards．
