摘　　要：在分析了海岸带水环境中多环芳烃的来源、分布的基础上,对其行为归宿也进行了论述。该憎水性有机污染物的行为受控于一系列物理、化学及生物过程。其中最重要的是物理迁移、化学及生物转化,还有在不同环境界面(大气、水、沉积物及生物)中的分布。同时也分析了控制PAHs在海岸带水环境中归宿的主要生物化学过程,这些过程包括挥发、沉积物-水中的分配、与可溶性有机物的作用、生物累积和降解。Based on the analysis of the sources and the distribution of the PAHs in the aquatic environment along the coastal zone, elevation and discussion about the behavior and fate were done. The fate of PAHs in the aquatic environment along the coastal zone is controlled by a variety of physical, chemical and biological transformations, and distribution of these compounds between the various environmental compartments (atmophere, water, sediments and biota). The major biogeochemical processes which control the fate of PAHs in the aquatic environment along the coastal zone are analyzed. These processes include the evaporation, sediment water partitioning, interaction with dissolved organic matter, bioaccumulation and degradation.
