摘要:
多溴二苯醚(PBDEs)属于新兴污染物,是一种性能优良的阻燃剂,在各种工业产品中广泛应用,而且存在于世界各地的海洋环境中。PBDEs还有持久性、远距离迁移性、生物累积性等特点,对海洋生态系统和人类造成严重危害。与此同时渤海又是我国唯一一个半封闭型的内海,有较差的自净能力以及与外界海水交换的能力,因此渤海区域PBDEs的研究在近十几年来受到了极大的关注。本文综述了PBDEs在渤海区域内的污染特征以及在不同介质中的含量水平与分布特征,并对与PBDEs相关的生态环境风险评价方式进行了总结,以期使读者深入了解渤海区域内PBDEs的污染现状及其危害,为以后此区域进行多溴二苯醚的污染防治和渤海生态环境治理等方面的工作提供可以借鉴的资料。

Abstract:
Polybrominated diphenyl ether (PBDEs),as the new type of persis tent organic pollutants and a flame retardant with excellent performance, It is widely used in a variety of industrial products and exists in marine environments all over the world. PBDES are also persistent, long-range and bioaccumulation, which pose a serious threat to marine ecosystems and human health. Bohai Sea is the only semi-enclosed Inland Sea in China, which has poor self-purification ability and exchange ability with the outside sea water. So the study of PBDES in the Bohai Sea region has received a lot of attention in recent decades. In this paper, the pollution characteristics of PBDEs in Bohai Sea, the concentration level, the ecological environmental risk assessment methods and distribution of PBDEs in different media are summarized. With a view to let readers understand the pollution status and harm of PBDEs in the Bohai Sea. The purpose of this paper is to provide reference data for the pollution prevention and control of polybrominated diphenyl ethers and the ecological environment control of the Bohai Sea in the future.
Key words:  Polybrominated diphenyl ether  Bohai Sea  Concentration  Distribution  Eco-environmental risk
