某典型加油站场地环境调查与健康风险评估

Site Environmental Investigation and Health Risk Assessment for a Typical Gas Station

以上海某加油站为研究对象,开展场地环境调查与健康风险评估并讨论场地修复目标值。调查发现,场地内土壤主要受总石油烃和多环芳烃污染,总石油烃对人体有非致癌危害,在可接受风险水平内;苯并（a）芘、二苯并（a,h）蒽具有致癌性,风险不可接受,修复面积100 m^2,修复理论土方50 m^3。初步建议苯并（a）芘、二苯并（a,h）蒽修复目标值分别为0.4、0.18 mg/kg。

Site environmental investigation and health risk assessment were carried out for a gasstation in Shanghai. Meanwhile, site remediation target values were also discussed. It was found that thesoil at the site has been mainly contaminated by total petroleum hydrocarbons and polycyclic aromatichydrocarbons, in which the former ones were non-carcinogenic and within an acceptable risk level, whilstbenzo （a） pyrene and dibenz （a,h） anthracene were carcinogenic and beyond the acceptable one. Therewas an area of 100m2 to be remedied with about 50m3 of earth in volume theoretically. The proposedcleanup goals for benzo （a） pyrene and dibenz （a,h） anthracene were set at 0.4 mg/kg and 0.18 mg/kg,respectively.
