摘　　要：为了探明山东果园土壤中PAHs的污染现状,应用ASE-HPLC技术测试山东红富士主产区果园土壤中PAHs的含量,并对土壤中16种PAHs的分布特征及其生态风险进行探讨。结果表明:15个检测点中有3个检测点存在PAHs污染,含量分别为201.51,833.88,861.28ng/g,说明目前山东苹果园土壤PAHs污染水平较低,生态风险较小,但个别果园已经达到中等污染水平,理论推断会对生态环境产生负面影响。通过分析土壤中PAHs组成可以看出,土样中Ilp/(Ilp+Bgp)值均位于0.20～0.50之间,说明土壤中PAHs主要来源为石化燃烧混合污染,可以作为防止果园土壤PAHs进一步污染的切入点。In order to explore Shandong orchard soil PAHs in pollution present situation, tested the Shandong Fuji producing orchard soil PAHs content with the ASE-HPLC technology, and discussed the distribution characteristics and ecological risk of 16 kinds of PAHs in the soil. The results showed that there were three controlling points existed PAHs pollution in 15 points, the content of which were 201.51, 833.88, 861.28 ng/g, and which showed that present the pollution level of PAHs in Shandong apple orchard soil was low, and the ecological risk was lesser, but individual orchard had reached secondary pollution level and theory inference would have a negative impact on the ecological environment. Through the analysis the composition of PAHs in soil, the Ilp/（Ilp＋Bgp） value were all located in 0.20 to 0.50, indicating that the soil PAHs main source for petrochemical combustion composite pollution, and it could be used to prevent orchard soil PAHs further pollution to point.
