中文摘要:
      以江苏省中部某城镇工业遗留场地为研究区域,采集23件土壤样品,检测土壤中多环芳烃(PAHs)、有机氯农药(OCPs)、总石油烃(TPH)和重金属含量并开展风险评估。结果表明:土壤中有机物检出因子18项均无超标;Zn和Cr最大值均超过浙江住宅及公共用地筛选值,其余重金属未超标。风险评估表明,在第一类用地和第二类用地中Cd的致癌风险分别为2.70×10-8和1.42×10-8,均小于可接受致癌风险10-6;在第一类用地和第二类用地中Cd、Cu、Hg、Zn危害熵范围分别为 0.023~0.542和0.006~0.060,均小于可接受非致癌危害熵1。Cd、Cu、Hg、Zn风险值均在可接受范围内。
英文摘要:
      Taking a legacy industrial site in a town in central Jiangsu province as the study area, the content of polycyclic aromatic hydrocarbons(PAHs), organic chlorine pesticides (OCPs), total petroleum hydrocarbon (TPH)and heavy metals in 23 soil samples were detected, and their risks were assessed. The results showed that 18 detected organics in soil did not exceed the standard. The maximum value of zinc and total chromium both exceeded the screening values of residential and public land in Zhejiang. The rest of heavy metals did not exceed the standard. According to risk assessment, the carcinogenic risk of Cd in the first and second type of land use were 2.70×10-8 and 1.42×10-8, respectively, both were below the acceptable carcinogenic risk of 10-6. The hazard quotient range of Cd, Cu, Hg, Zn in the first and second type of land use were 0.023~0.542 and 0.006~0.060, respectively, both were less than the acceptable non carcinogenic hazard quotient of 1. The risk values of Cd, Cu, Hg, Zn were all in the acceptable range.
