| 摘 要： | 为研究城市河流河岸带土壤中多环芳烃（PAHs）的污染特征,于2010年8月沿温州九山外河和山下河河岸带采集了21个表层土壤样品,利用加速溶剂萃取仪（ASE）萃取,净化柱提取净化,使用气相色谱-质谱联用仪（GC-MS）分析了土壤中18种PAHs的含量.结果表明,温州九山外河和山下河河岸带表层土壤中PAHs含量范围为60.7～3 871.3 ng·g-1,山下河河岸带土壤中ΣPAHs含量显著低于九山外河.两条河流河岸带土壤中的PAHs均以2、3环的低环为主,平均占到PAHs总量的62.47%～72.51%.与国内外其他研究地区土壤中PAHs含量相比,研究河段河岸带土壤中的PAHs处于中等污染水平,但有3个样品中BaP浓度远大于前苏联土壤标准,应引起足够重视.利用Ant/（Ant＋Phe）和Fla/（Fla＋Pyr）比值法和主成分分析方法进行判源,温州城市河流河岸带土壤中的PAHs均表现出明显的燃烧源和石油源的综合来源特征。
