辽河流域浑河沈阳段地表水重点控制有机污染物的筛选

The sifting of priority control organic pollutants in hunhe river of liaohe basin in shenyang city

采用美国环保局工业环境实验室提出的化学物质的“潜在危害指数法”,对辽河流域浑河沈阳段地表水和底质中检出的有机污染物的潜在危害进行了排序,参考国内外有毒化学品优先控制名单的筛选原则和方法,结合本流域的实际情况,制定出重点控制有机污染物的评分标准,提出辽河流域浑河沈阳段重点控制有机污染物名单。考虑到个别有机污染物在水中的浓度很低,但在底质中相对含量较高,所以将底质的检测结果也纳入评分标准。

Refer to some sifting principle and methods for priority control toxic chemicals at home and abroad and the Potential Index of harm advanced by the Industry Environmental lab of U.S. EPA, the evaluating criteria are established for the priority control organic pollutants in Hunhe River of Liaohe Basin in Shenyang city according to the pollution status. The priority control pollutants in this area are list, Although the concentration of some pollutants is low in surface water, the analysis results of these organic pollutants in sediment are considered in the evaluating criteria because the concentration of these compounds is high in sediment.
