PBDEs研究的最新进展

Advances on Study of Polybrominated Diphenyl Ethers

多溴联苯醚(PBDEs)是一类环境中广泛存在的全球性有机污染物。由于其具有环境持久性、远距离传输、生物可累积性及对生物和人体具有毒害效应等特性,对其环境问题的研究已成为当前环境科学的一大热点。本文对最近几年来环境中PBDEs研究的进展进行综述,对多溴联苯醚在环境及生物体中的分布、时间趋势、人体暴露及途径、环境中的降解和生物代谢以及生物累积与生物放大方面的研究进行了总结,对目前存在问题及进一步的研究方向进行了讨论和展望。

As a kind of global environmental contaminants, polybrominated diphenyl ethers （PBDEs） are ubiquitous in environment. Due to its persistency, long distance transportation, bioaccumulation potential in organisms and adverse effects on wildlife and human health, investigations on the environment concerns of PBDEs have rapidly increased in last decade. This paper summarizes the advances on study of PBDEs in recent years. Recent data on the environment distributions, time trends, human exposure and route, degradation and biotransformation, and bioaceumulation of PBDEs are reviewed. The currently knowledge gaps and critical areas of research that warrant further attention are also discussed and provided.
