摘　　要：在总结国内外学者研究的基础上,针对多溴联苯醚(PBDEs)的环境行为及降解方法进行了综述。结果表明,PBDEs在水、大气、土壤和生物体等环境中均能稳定存在,降解PBDEs的方法主要集中在生物降解和光降解2个方面,但均存在一定局限性,有关降解机理报道甚少,亟需研发新的降解PBDEs方法和探索降解机理,并就以臭氧为基础的高级氧化法降解环境中的PBDEs进行了展望。Based on the researches both at home and abroad, the environmental behaviors and degradation of polybrominated diphenyl ethers （PBDEs） were reviewed. The results showed that PBDEs can exist stably in water, air, soil and biota, and it is mairdy degraded by photodegrada- tion and biodegradation,which still have some limitations. What＇ s more, there is little information about the degradation mechanism of PBDEs, so new degradation ways and possible mechanism are needed. Finally, ozone oxidation, one of the advanced oxidation processes, had been discussed.
