%X 近年来，非点源(NPS)污染已成为发达国家和发展中国家面临的全球性重大问题。由于各种人为活动产生的非点源污染，导致有机化合物(如药物化合物和农药)和无机养分(如Cu、Pb、Zn等重金属)过量排入到地表水和土壤中，从而改变水质和土壤环境，影响土壤和水生生态系统，破坏食物链和生态链网。因此有效减少非点源污染物负荷的方法或处理工艺越来越受到重视。采用模拟自然且环境友好的人工湿地(CWs)对非点源(NPS)污染进行生态修复近年来已在许多国家引起重视。但关于处理不同来源的非点源污染，特别是重金属污染的资料仍然没有得到充分的总结，所以本文重点介绍了人工湿地技术去除非点源重金属污染的最新进展，重点概述和回顾了非点源污染中重金属污染来源、迁移、转化及其生态毒理学效应。结果表明，人工湿地中的植物能通过各种可能的机制去除重金属污染物，其他因素(如微生物、基质)也起到了协同的作用。<br />
Recently, non-point source pollution has become a major global problem faced by developed and developing countries. Due to non-point source pollution caused by various human activities, organic compounds (such as pharmaceutical compounds and pesticides) and inorganic nutrients (such as Cu, Pb, Zn and other heavy metals) are discharged into surface water and soil in excess, which is changing water quality and soil environment. The continuous discharge of non-point source pollutants has a major impact on soil and aquatic ecosystems, making against the food chain and ecological chain network on the earth. Therefore, more and more attention has been paid to the methods or treatment processes to effectively reduce the load of pollutants. In recent years, the use of con-structed wetlands (CWS) for ecological restoration has attracted considerable attention in many countries, because most of them simulate natural and environment-friendly processes. Although it has a sufficient record of success in dealing with point source pollutants, the information on dealing with non-point source pollution from different sources has not been fully summarized. Therefore, this paper focuses on the sources, migration, transformation and ecotoxicological effects of heavy metals in non-point source pollution. It involves the importance of plants existing in constructed wetlands to help remove heavy metal pollutants through various possible mechanisms. The results indicate that plants in artificial wetlands can remove heavy metal pollutants through various possible mechanisms, and other factors (such as microorganisms and substrate) also play a synergistic role.
