摘　　要：添加型阻燃剂多溴联苯醚(PBDEs)由于具有优异的阻燃性能,已被广泛应用于各种消费品中。PBDEs具有低水溶性,会强烈吸附有机物,导致PBDEs在环境介质和食物链中大量富积,对人类和动物都造成巨大危害。对多溴联苯醚生物降解、光降解和零价铁降解过程中的代谢途径和代谢过程中所需的酶进行综述,为多溴联苯醚的修复提供理论基础。Polybrominated diphenyl ethers （PBDEs） have been widely used as additive flame retardants in many consumer products because of their demonstrated fire retarding abilities. Due to their hydrophobic nature, PBDEs tend to be adsorbed strongly by organic matter,which leads to their accumulation in environment and in the food chain. PBDEs could pose emerging risks to humans and other animals. This review proposes a general description of catabolic pathways and requisite enzymes for the degradation of PBDEs in terms of biodegradation, photolysis and zero-valent iron-induced degradation, and aims to provide theoretical basis for PBDEs remediation.
