| 摘 要： | 选取案例填埋场7种目标污染物为研究对象,运用3MRA模型模拟污染物在填埋场周围环境介质中的迁移转化.结果表明,7种目标污染物最低安全填埋阈值大小顺序为:污染物二价镍>苯>镉>铅>六价铬>砷>汞;污染物苯、砷、汞各自的人类和生态受体安全填埋阈值相同,镉和二价镍的人类受体安全填埋阈值高于生态受体,六价铬的生态受体安全填埋阈值高于人类受体,场区地下水的致癌风险和危害商分别为5.06×10-7和2.3×10-1.

| Abstract: | Seven major contaminations of the landfill were selected from northeast of China, and the migration and transformation of contaminations environmental medias were studied by using the multimedia multipathway and multireceptor risk assessment (3MRA) model. The results show, the order of the radical concentration of the seven contaminations is Ni2+ > Benzene > Cd > Pb > Cr6+ > As > Hg. The radical concentration of benzene, As and Hg in human is similar to that of ecology, respectively. The radical concentration of Cd and Ni2+ in human is higher than that of ecology, while the radical concentration of Cr6+ in ecology is higher than that of human. The risk and hazard quotient of the groundwater in the landfill is 5.06 x 10(-7), 2.3 x 10(-1), respectively. |
