中国地表水重金属污染的进展研究

摘要

为了解中国地表水重金属污染现状,并为水体重金属的治理提供一定依据,通过对地表水体重金属来源、中国各地区地表水重金属污染状况、水体重金属污染防治现状、风险及趋势分析和防治对策这五个方面进行综述.道路雨水径流的无处理排放易造成地表水体重金属的污染;中国许多地区的河流、湖泊等水体都存在重金属污染现象,不同地区污染来源不同,外源污染物输入是重要因素;致癌物镉、铬和砷对人体的健康风险要远远大于非致癌物.%In order to understand the current situation of heavy metal pollution in surface water and provide a basis for the treatment of heavy metal in water, this study introduced the current situation, source, countermeasures, risk, trends of heavy metal pollution in surface water in China.It is concluded that vehicle exhaust emissions in anthropogenic sources has become an important source in heavy metal sources.Because of human activities, a large amount of lakes and rivers have been contaminated so far.Cd, Cr and As are much larger than the non-carcinogens on human health risk.
