摘 要：
采用高效液相色谱系统对山西某钢铁工业园区及周边土壤样品中的16种美国环境保护署(EPA)优先控制的多环芳烃(PAHs)进行了分析,同时应用相对丰度法和比值法对土壤中的PAHs来源进行解析,并运用效应区间中值ERM(the effects range median)和效应区间低值ERL(the effects range low)进行生态风险评价.结果显示,山西某工业园区及周边土壤中PAHs的总含量为186.354~1 021.311μg/kg,平均值为487.726μg/kg,在国内外属于较低污染水平;燃烧源为该园区及周边土壤中PAHs的主要来源,其次为石油类污染源;该地区土壤PAHs的生态风险水平较低.

摘 要：
The concentrations of 16 US EPA polycyclic aromatic hydrocarbons(PAHs)priority pollutants were analyzed in 28 soil samples collected from steel industrial areas in Shanxi province, detecting with a high performance liquid chromatography(HPLC).Meanwhile, the principal sources were analyzed by using PAHs rings and specific value and the ecological risk of PAHs were evaluated based on the ERM(effects range median values)and the ERL(effects range low values). The results showed that the total of 16 PAHs ranged from 186.354 μg/kg to 1 021.311 μg/kg, and the average was 487.726 μg/kg. It was at a lower pollution level compared with the concentrations in soil at domestic and foreign. The main source of PAHs in steel industrial areas were combustion products of coal and fossil fuels, the followed were oil pollution. Risk assessment indicated that PAHs in the soil did not seriously threaten the environment.
