摘要
以上海某多环芳烃(PAHs)污染场地为研究对象,通过对该场地内土壤的PAHs污染物浓度与我国建设用地及农用地标准比对、内梅罗指数法污染评价、质量基准法与质量标准法分析污染特征,评价该场地内土壤样品中PAHs污染情况及生态风险。结果表明:该场地的MW2和MW6两个点位的表层土壤样品苯并(a)芘超过了相关标准限值,两个点位已存在PAHs的累积现象,应给予足够重视,并有必要对该两个点位开展PAHs污染来源调查以及生态修复,对其余监测点位需加强后续监测并制定详细控制计划。
This paper considers a site in Shanghai contaminated with polycyclic aromatic hydrocarbons (PAHs) as a research object and compares the concentration of PAHs in the soil with soil from construction and agricultural sites in China and utilizes the Nemero index method for pollution evaluation and quality benchmarking. Further, a quality standard method is used to analyze the pollution characteristics of eight different types of PAHs in soil samples from the site and to evaluate the pollution and ecological risk of the PAHs present in the samples. The results show that the BAP of the surface soil samples at the two points at the site exceed the relevant standard limits and that accumulated PAHs already exists at these points, which thus require attention. The results suggest that the source of PAH pollution must be investigated, ecological restoration research must be conducted, robust monitoring programs should be implemented for the impacted points, and detailed control plans should be developed for the remaining monitoring points.
