淮河流域水体持久性有毒污染物的研究现状

Current Status of Persistent Toxic Substances in Huaihe River Basin

持久性有毒污染物(persistent toxic substances,PTS)是一类在环境中难降解,可远距离传输,具有生物累积性、"三致"毒性(致畸、致癌及致突变性)和内分泌干扰等特性的污染物。本文综述分析了近年来有关淮河流域水体持久性有毒污染物的研究现况,介绍了淮河流域不同水体不同段中污染物的种类及污染水平。淮河流域水体(沉积物、地表水、地下水)中PTS的研究大多集中于多环芳烃(PAHs)、有机氯农药(OCPs)和重金属等。PTS对研究区构成了潜在健康威胁。最后对相关研究的前景加以展望。

Persistent Toxic Substances（PTS） are kinds of pollutants persistent and bio-accumulated in the environment,with characteristics of teratogenic,carcinogenic and mutagenic toxicity and endocrine disruption. This review described the current status of persistent toxic substances in Huaihe River Basin. The kinds and levels of pollutants in different water-bodies were introduced. Most of studies on the PTS in water-body（sediment,surface water and groundwater） in Huaihe River Basin have focused on polycyclic aromatic hydrocarbons（PAHs）,organochlorine pesticides（OCPs） and heavy metals. PTS constitute a potential health threat to the study area. Finally,the perspectives for further research were proposed.
