潜在危害指数在水环境优先污染物筛选中的改进与应用

The Improvement and Application of Potential Damage Index in Screening Priority Pollutants in the Water Environment

随着经济的迅猛发展,水环境污染问题倍受瞩目,尤其是有机污染物对人体的危害。所以合适的优先污染物的筛选方法对了解水环境中有机污染物的危害程度十分必要。文章对潜在危害指数在水环境优先污染物筛选中的不足进行分析,并提出修改方案;简要介绍了以潜在危害指数为重要指标的综合评分法和加权评分法,并对两者进行了比较;提出将来潜在危害指数的发展方向。

With the development of economy, the water environmental problem was becoming more and more serious, especially for the harm of organic pollutants. Therefore, appropriate screening method for priority pollutants in water environment on the understanding of harmful levels of organic pollutants is necessary. This paper analyses the defects of potential damage index used in screening priority pollutants in the water environment and gives the modifying suggestions. In addition, introduced the comprehensive marking method and weighted marking method in which potential damage index was used and gave the differences. Proposed the developing direction of potential damage index.
