摘要
地块地下水受总石油烃污染,未来规划为敏感用地,受体暴露途径有3种,依据总石油烃分段毒性、理化性质,对各分段总石油烃进行筛选值计算,脂肪烃C10-C12、C13-C16、C17-C21、C22-C40、芳香烃C10-C12、C13-C16、C17-C21、C22-C40基于人体健康的筛选值为0.55、0.314、17.2、15.8、0.023、0.023、0.029、0.029 mg/L,为同类型场地地下水总石油烃风险评估与修复提供案例借鉴。
The ground water in the block was polluted by total petroleum hydrocarbon, and the block was planned as sensitive land in the future. There were three ways to expose sensitive receptors. According to the segmented toxicity and physicochemical properties of total petroleum hydrocarbons, the selected values of total petroleum hydrocarbons in each segment were calculated. The screening values of aliphatic C10-C12、C13-C16、C17-C21、C22-C40、aromatic C10-C12、C13-C16、C17-C21、C22-C40 based on human health were 0.55, 0.314, 17.2, 15.8, 0.023, 0.023, 0.029 and 0.029 mg/L. The project provided a case study for the risk assessment and remediation of total petroleum hydrocarbon in groundwater of the same type of site.
