ABSTRACT
Polybrominated diphenyl ethers(PBDEs) are widely present in the world and their concentration in the environment has been increasing rapidly.PBDEs pollution has caused an extensive concern in recent years.The environmental effects of PBDEs are decided by their transfer and transformation,which is the basis of environmental and health risk evaluation.At present,a considerable number of detection of PBDEs has been undertaken in sediment and wildlife.However,little research has been done on the ecotoxicology of PBDEs.The purpose of this paper was to introduce the research status of PBDEs,to summarize emphatically their distribution model,bioaccumulation regularity and ecotoxicology effects in the environment,and to discuss the influences of PBDEs on human health.Finally the problems needed to be solved in this field are proposed.
