摘　　要：六溴环十二烷(Hexabromocyclododecane,HBCD)是一种广泛使用的添加型阻燃剂,其具有持久性、生物积累性、生物毒性以及可远距离迁移性等特点。HBCD不会直接施用于农田土壤,但会随着一系列的环境行为进入其中并被土壤有机质吸附,使土壤成为HBCD的“汇”。土壤中的微生物和植物等生物活动会使HBCD进入生物链并对人类健康造成威胁。土壤生物修复方法具有修复成本低、操作简单、高效安全等特性,符合农田土壤绿色发展的目标导向,越来越多地被应用到土壤修复当中。本文重点阐述了农田土壤中HBCD的污染过程,包括污染源、环境行为,并对HBCD的生物修复方法进行了总结分析,以期为农田土壤中HBCD的高效阻控以及污染土壤的绿色修复提供有益参考。Hexabromocyclododecane(HBCD)is a widely used additive in brominated flame retardants(BFRs)and is known to be persistent,bio-accumulable,toxic to ecosystems,and capable of being transported over long distances.Although HBCD is not applied directly to agricultural soils,it can enter soil via a series of environmental routes and be adsorbed by soil organic matters.It could also pose a threat to human health via bioaccumulation through the food chain.Bioremediation has increasingly been applied as a soil remediation technique because it is low cost,easy to use,highly efficient,highly safe in the environment,and supports the goal of developing agricultural soil in a green manner.This study summarized and analyzed the process by which HBCD pollutes agricultural soil,including via its sources and environmental behaviors,and the bioremediation methods to mitigate it,aiming to provide a useful reference for the effective control of HBCD in agricultural soils and the green remediation of soil pollution.
