| 摘 要： | 采集黄河三角洲石油开采区滨州市89个土壤样品(其中:83个农田土壤样品,6个石油开采区土壤样品),采用气相色谱-质谱仪(GC-MS)分析土壤中的16种EPA优控的多环芳烃(PAHs)组成与含量,运用主成分分析(PCA)和正定矩阵因子法(PMF)模型判断农田土壤中多环芳烃的来源.结果表明,农田土壤中16种PAHs总含量(以干重计)范围31. 5～1 399. 4μg·kg~(-1),其平均值为149. 8μg·kg~(-1). PAHs组成特征表明,该地区农田土壤中主要以4～6环多环芳烃为主,单体PAH间大多呈显著相关(P 0. 01),表明采样区某些单体PAH的污染来源具有一定的相似性.两种源解析方法对多环芳烃的来源判定有相似的结果,农田土壤中PAHs主要来源于燃煤、生物质燃烧、化石燃料燃烧以及柴油燃烧; 4类源的贡献率依次是汽油燃烧(24. 05%)、柴油燃烧(6. 17%)、低温热解过程(60. 67%)与煤燃烧(9. 11%).
