我国水体中持久性有机污染物的分布及其对鱼类的风险综述

持久性有机污染物(POPs)具有高毒、持久、生物累积、远距离迁移等特性,严重威胁环境生物和人类健康。水体是POPs在环境中迁移转化的重要介质,其在水体中可通过迁移、吸附、沉降等作用及食物链对不同种类水生生物的生长、发育及生殖产生影响。作者整理了近年来我国学者对水域中POPs的监测结果,就此类化合物在我国水体中的分布情况进行了综述。鱼类作为地表水生态系统中最主要的脊椎动物,具有重要的环境指示作用。本文通过对POPs对鱼类毒性数据的分析,评价了我国主要水域中POPs对鱼类的危害,旨在为揭示此类化合物的水生生态风险提供参考。

The occurrence of persistent organic pollutants in China and their environmental risk to fish: a review

Persistent organic pollutants (POPs) have posed a threat to the human health, environment and animals, as they are persistent, highly toxic, biological accumulative and migrative. Waterbody is an important medium for the transfer and transformation of POPs in the environment. In waterbody, the growth, development and reproduction of aquatic organisms can be affected by POPs through migration, adsorption, sedimentation and food chain. This review summarized the reported results of the POPs monitoring and reviewed the occurrence and distribution of POPs in main water areas of China.As a main vertebrate, fish in the aquatic ecosystem is an important environmental indicator. In this work, the risk of POPs to fish that living in polluted areas was further evaluated according to the toxic data of POPs. This work would provide scientific evidence for revealing the environmental risk of POPs.
