摘　　要：第二松花江中下游河段8个底泥中多环芳烃(PAHs)分析表明,5种多环芳烃含量和多环芳烃总量随取样点位置发生明显的变化,城区河段底泥中各种PAHs含量和PAHs总量均高于非城区河段。2环加3环与5环PAHs化合物分布特点表明第二松花江中下游非城区河段底泥中PAHs的来源以石油类污染为主,而城区河段PAHs的来源则主要是化石燃料高温燃烧。第二松花江中下游河段(尤其是城区河段)底泥中PAHs具有较高生态风险,可能会对生物产生一定的负面影响。The analytical results of polycyclic aromatic hydrocarbons （PAHs） in 8 bottom mud samples from middle and lower rea-ches of Second Songhua River show that the contents of 5 kinds of PAHs and total PAHs vary dramatically with the sampling loca- tions and the contents of these pollutants in the samples from the urban area are higher than those from rural area. The distribution characteristics of PAHs with 2 ＋ 3 ring and 5-ring compounds from the analytical data in bottom mud samples show that petroleum- derived contamination may be the dominant source in the rural area, while the combustion of fossil fuel may be the possible source in the urban area. The PAHs in bottom mud in the middle and lower reaches of the second Songhua River, especially in the urban are-a, have stronger ecological risk and may produce negative biological effects.
