摘　　要：报道了长江和辽河沉积物中１７种多环芳烃（ＰＡＨｓ）类污染物的含量及分布状况．所研究的长江南京段沉积物中多环芳烃总量变化范围为 ２１３．８～５５０．３２ｎｇ／ｇ（干重），辽河新民段沉积物中多环芳烃总量变化范围为 ２７．４５～１９８．２６ｎｇ／ｇ（干重）．测定结果表明，长江和辽河沉积物中多环芳烃具有不同的空间分布模式：长江段以南京市下游的沉积物中ＰＡＨｓ含量为最高，而辽河段则以新民市区的沉积物中ＰＡＨｓ含量为最高但总的来说，长江南京段沉积物中多环芳烃的污染水平明显高于辽河新民段沉积物所受的多环芳烃污染．Contamination levels of 17 kinds of polycyclic aromatic hydrocarbons (PAHs) in the sediments of the Yangtse River (Naming section) and the Liaohe River (Xinmin section ) were reported in this paper. The total concentrations of PAHs in the studied Yangtse River ranged from 213.8ng/g to 550.32ng/g of dry weight while in the studied Liaohe River ranged from 27.45ng/g to 198.26ng/g of dry weight. PAHs contamination pattern was different in the sediment of the Yangtse River and the Liaohe river. Higher levels of PAHs were detected after the Yangtse River passed through Naming while in the Liaohe River higher levels of PAHs were found in Xinming. But on the whole, PAHs levels in the Yangtse River (Nanjing section) were much higher than in the Liaohe River (Xinming section).
