摘　　要：综述了持久性有机污染物(POPs)的生物降解途径,以及国内外在外生菌根真菌降解POPs方面的研究进展,阐述了其机制与优势.根据作用的微生物和环境条件的不同,POPs如PCBs、DDT等可以通过脱氯或开环等途径生物降解.外生菌根真菌能降解多种POPs,具有较大的潜力.The pathways for biodegradation of persistent organic pollutants （POPs） are summarized and the potential capability of ectomycorrhizal fungi （ECMF） to degrade POPs is described in this review. POPs, such as PCBs and DDT, can be metabolized through the process of dechlorination or ring cleavage, according to the microorganisms and environmental conditions. Many researches show that a lot of ectomycorrhizal fungi can degrade several POPs. The likely mechanisms by which ECMF can biodegrade POPs are suggested, and their advantages and constraints are proposed in this paper. Fig 2, Tab 2, Ref 30 .
