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海水、沉积物和生物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:
In the past few decades polybrominated diphenyl ethers (PBDEs) have emerged as a new class of persistent organic pollutants (POPs) owing to their accumulation in the marine environments all across the globe. PBDEs are widely used as a flame-retardant and are fount to exist is in a variety of industrial products including textiles, paints, rugs, automobiles, and airplanes. The characteristics of persistence, bioaccumulation, and long-range transportation make PBDEs a serious threat to marine ecosystems and human health. The Bohai Sea is the only semi-enclosed inland sea in China. Its poor ability of self-purification and exchange water with the outside of Bohai Sea has been found to be associated with the high pollution load present in this waterbody. Evaluation of PBDEs accumulation in the Bohai Sea region has received a significant attention in the recent decades. The current study aimed to provide an overview of the pollution status of the Bohai Sea and evaluate the harmful effects of the accumulated PBDEs. With a view to provide an overview of the pollution status of the Bohai Sea and the harmful effects of the accumulated PBDEs, the present work describes in detail the pollution characteristics and concentration levels of PBDEs in sea water, sediments and biological media of the Bohai Sea, methods used for ecological and environmental risk assessment, and distributions of PBDEs in water and sediment. The information thus obtained will be helpful in the prevention and control of pollution arising due to PBDEs accumulation which will further maintain the ecological and environmental serenity/balance of the Bohai Sea in the near future.
