多溴联苯醚(PBDEs)污染已在世界各地普遍存在,且其浓度在环境中快速增长,所以受到人们的广泛关注。环境中的PBDEs的迁移规律决定其环境效应,是进行环境和健康风险评价的基础。目前关于PBDEs的研究主要集中于沉积物及生物体内的PBDEs分析检测,对其生态毒理效应的研究尚处于起步阶段。该文概述了PBDEs的研究现状,着重介绍了PBDEs在环境中的分布模式、在生物体内的蓄积规律以及环境中PBDEs的生态毒理效应等方面的研究进展,同时也阐述了PBDEs污染对人体健康的影响,并提出了PBDEs研究亟待解决的问题。
Polybrominated diphenyl ethers (PBDEs) have been widespread in the world and their concentrations have rapidly increased in the environment. Therefore, they have drawn much attention. The migration of PBDEs in the environment determines the environmental effects and is the basis for environmental and health risk assessment. At present, the research on PBDEs mainly focuses on the analysis and detection of PBDEs in sediments and organisms, and the study of its ecotoxicological effects is still in its infancy. This paper summarizes the research status of PBDEs, emphatically introduces the distribution of PBDEs in the environment, the accumulation law in the living body and the ecotoxicological effects of PBDEs in the environment. At the same time, it also expounds the impact of PBDEs on human health And put forward the problems to be solved in the research of PBDEs.
