摘　　要：多溴联苯醚(PBDEs)属溴代阻燃剂,是一类分布广、难降解、高生物毒性的持久性有机污染物,具有极高的生态风险。开展PBDEs降解途径的研究,可降低典型环境中持久性有机污染物的污染风险,在其污染修复治理等方面具有重要的科学意义。该文在分析PBDEs结构、种类及危害的基础上,对国内外PBDEs降解途径研究近况进行了系统的总结与评述,分析了光降解、零价铁降解、微生物降解等降解方式的优点与不足,并对多溴联苯醚降解的研究进行了展望,为持久性有机污染物的相关降解研究提供参考借鉴。Polybrominated diphenyl ethers(PBDEs)as brominated flame retardants,are a class of persistent organic pollutants with wide distribution,refractory and high biotoxicity,which have extremely high ecological risks.The research on the degradation pathway of PBDEs can reduce the pollution risk of persistent organic pollutants in typical environments,and has important scientific significance in its pollution remediation and management.Based on the analysis of the structure,types and hazards of PBDEs,this paper systematically summarizes and reviews the recent research on the degradation pathways of PBDEs at home and abroad,and analyzes the advantages and disadvantages of degradation methods such as photodegradation,zero-valent iron degradation and microbial degradation.The research on the degradation of polybrominated diphenyl ethers is prospected,which provides reference for the research of related degradation of persistent organic pollutants.
