摘　　要：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。文中对国内外各地表层沉积物中多环芳烃的浓度的进行对比的基础上,分析了我国水体沉积物中多环芳烃的污染现状,结果表明处于低-中等水平,就而部分区域如黄河流域的沉积物达到高生态风险区的标准。Polycyclic asomatic hydrocarbon （PAHs） are organic pollutants which exist in environment widly. Generally, the final of PAHs are sediment. The degree of sediment contamination by PAHs in China oaupy moderate/low in comparison with other internal and external estuarine and river surface sediments. However, the comparisons of the concentrations of a number of PAHs to the biologic threshold from abroadindicated that diments from some part of Chian as Yellow River were most likely to pose bilogical impairment.
