摘　　要：近年来各地大量粗放地使用消毒剂、杀菌剂等含氯化合物,导致土壤中的氯积累量逐步增加,从而对土壤动物、植物和微生物带来严重危害。然而,有关有毒含氯化合物对土壤生物的影响机制并不清楚,如何高效修复有毒含氯化合物污染土壤的技术还少见报道。综述了土壤中不同含氯化合物之间的形态转化、含量现状及毒害机理,阐述了有毒含氯化合物污染土壤的生物修复技术的优势和不足,并提出了改进措施,可为有毒含氯化合物在土壤中的风险评估及治理修复提供理论基础。The accumulation of toxic chlorine-containing compounds in soils has been a serious issue due to their long existence and unpredictable risks posed to animals,plants and microorganisms in soils.However,the mechanism by which these chlorine-containing compounds affect soil organisms is still unclear.There are few reports on how to efficiently remediate soils contaminated by toxic chlorine—containing compounds,few studies reviewed the advantages and disadvantages of these remediation technologies.In this study,the morphological transformation,existing content and toxicity mechanism of different chlorine-containing compounds in soils were reviewed.Moreover,different bioremediation technologies for soils contaminated by toxic chlorine-containing compounds were analyzed,and appropriate solutions for improving remediation efficiency in case of contamination caused by these compounds in soils were proposed.The findings in this review provide new insights into the risk assessment and remediation of toxic chlorine-containing compounds in soils.
