Deriving of Soil Guideline Values and Risk Assessment of Polycyclic Aromatic Hydrocarbons at a Typical Petrochemical-Contaminated Site

  • 摘要: 尝试利用英国的污染土地暴露评价模型(CLEA模型)获取了典型石油化工污染场地中几种多环芳烃(PAHs)的土壤指导限值(SGVs),并用所得到的土壤指导限值对该场地的污染物风险进行了评价.结果表明,研究区域内萘、蒽、苯并[a]芘、苊、芴、芘的土壤指导限值分别为3.57×103,6.12×107,0.874,6.81×104,6.24×104和5.84×106 ng/g.特定场地表层土壤中萘、蒽、苊、芴、芘的实测浓度(MECs)大于其相应土壤指导限值的概率均趋于0,而苯并[a]芘的为0.225.这几种PAHs的风险从大到小依次为:苯并[a]芘萘>苊>芴>芘>蒽,说明该场地的优先控制污染物为苯并[a]芘.
