摘　　要：六氯丁二烯是2015年列入《关于持久性有机污染物的斯德哥尔摩公约》进行管控的新持久性有机污染物(POPs)。六氯丁二烯在环境中难降解、可长距离迁移、具有生物富集性,对生物和人类健康具有潜在危害。目前对六氯丁二烯排放源的认识还非常缺乏,对其环境污染特征的研究还不够系统,针对六氯丁二烯的控制技术和策略有待开发。本文总结了六氯丁二烯的环境和生物赋存水平,梳理了六氯丁二烯的管控过程、潜在排放源及排放量,并讨论了六氯丁二烯的生成机理、自然环境中的降解过程、以及相关的减排策略和控制技术。本文可为控制六氯丁二烯的源排放、减少环境污染水平和降低人体暴露提供参考。Hexachlorobutadiene(HCBD)is a new persistent organic pollutant(POPs)added into the Stockholm Convention on POPs since 2015.HCBD has attracted worldwide attention due to its persistence,bioaccumulation,and potential for long-range transport,with potential adverse effects on humans and biota.However,the knowledge about the source,environmental characteristics,control techniques and strategies are still very lacking.The levels of HCBD in environmental and biological samples are summarized and analyzed in this review.The control process,potential emission sources and emission amount of HCBD are reviewed.The formation mechanism of hexachlorobutadiene,the degradation process in natural environment,and the related emission reduction strategies and control technologies are discussed.This paper can provide important reference for controlling the emission of HCBD,reducing their environmental level,and reducing human exposure.
