Environmental pollution by polybrominated diphenyl ethers (PBDEs) and their ecological chemical behaviors: A review
多溴二苯醚(PBDEs)对环境的污染及其生态化学行为

As a specific group of brominated flame retardants(BFRs),polybrominated diphenyl ethers(PBDEs) are widely used in a variety of household and industrial products,including electronics and household furnishings.It was reported that the concentrations of PBDEs are increasing exponentially in biota and abiota in recent years.Because of their lipophilicity and persistence,PBDEs can be bio-accumulated and bio-magnified in biota.In addition,PBDEs are evaporable to some extent,and thus,they can undergo long-distance transport to remote ecosystems.Many evidences indicated that PBDEs have definite toxic effects and endocrine disruption.From the aspects of ecological chemical behavior and eco-toxicity,this paper summarized the research results about the distribution and occurrence level of PBFRs in the environment as well as their toxic effects and behaviors in endocrine disruption,analyzed the existing problems in related researches,and discussed the research directions on PBDEs.
