摘要
含硫有机微污染物在国内外自然水体中高频检出,其主要包含生产生活中广泛应用的含硫医药和农药,具有难降解性及生物毒性,已形成较高环境风险.本文系统总结了含硫有机微污染物的种类及典型污染物理化性质,全面综述了其在水环境中的来源、环境风险及污染现状,采用文献计量学方法重点分析了含硫有机微污染物的去除技术及机理,并从优化污染物高精确度检测手段、完善复合污染物风险评估方法、开发高选择性的污染控制技术、建立效价官能团-环境效应数据库、加强区域水循环体系协同治理5个方面展望了未来研究的热点趋势,以期为水环境中含硫有机微污染物的有效削减及风险防控提供参考.
Abstract
Sulfur-containing organic micropollutants are frequently detected in natural water at home and abroad,mainly including sulfur-containing pharmaceuticals and pesticides widely used in production and life,which are difficult to degrade and biotoxic,and pose a high environmental risk.In this paper,the types and physicochemical properties of sulfur-containing organic micropollutants are systematically summarized,and their sources,environmental risks and pollution status in water environment are comprehensively reviewed.The removal technology and mechanism of sulfur-containing organic micropollutants are emphatically analyzed by bibliometric methods.And the hot trends of future research are prospected from five aspects:optimizing the high precision detection method of pollutants,improving the risk assessment method of complex pollutants,developing the highly selective pollution control technology,establishing the database of characteristic functional groups-environmental effects,and strengthening the cooperative governance of regional water cycle system,in order to provide reference for the effective reduction and risk control of sulfur-containing organic micropollutants in water environment.
