摘　　要：水体沉积物是水体生态系统的重要组成部分,是水体多种营养物、污染物的汇(Sink)和源(Source),是众多污染物在环境中迁移转化的载体、归宿和蓄积库。多环芳烃(PAHs)是一大类广泛存在于环境中的有机污染物,在水体中其主要归宿是沉积物。文中详细论述了多环芳烃在天然水体中迁移、转化规律,并浅述了多环芳烃在沉积物中的生态效应。As an important components in the water ecosystem,aquaticsediment was the sink and source of mutiple nutrients and pollutants and carrier,fate and accumulation of numerous pollutants migrating and trabsformating in the environment.PAHs the organic pollutants,were widely existing in the environment and fated by deposition in waters.The migration and transformation rule of PAHs in natural water were discussed detailly,and the ecological effects of PAHs in the sediments were described briefly.
