摘要
水环境是多溴联苯醚(PBDEs)的主要环境归宿之一,研究水环境中PBDEs污染对于了解PBDEs的环境生物地球化学过程及其生态风险具有重要意义。基于水相、沉积相和水生生物中PBDEs污染的报道,从多介质分布特征、污染来源、变化趋势以及PBDEs的水生生物累积和生物放大等方面综述了水环境中PBDEs的污染及其生态风险,并讨论了我国水环境中PBDEs污染及其研究进展,指出了研究存在的问题和进一步研究的重点。
Polybrominated diphenyl ethers （PBDEs） could enter into aquatic environment by varieties of means. The researches concerned on their pollutions in aquatic environment are of great significance to the understanding of the PBDE biogeochemical processes and their ecological risks. Based on the PBDE levels in water, sediments and aquatic organism, this paper attempts to review the distribution characteristics, possible sources, trends, bioaccumulation, biological magnification and risks of PBDEs in aquatic environment. Further, the status of PBDE pollutions and the progress in their researches of China were summarized. At the same time, the shortage and the trends of the researches of PBDEs in aquatic environment are discussed in order to provide valuable reference for the researchers and managers.
