| 摘 要： | 选用美国环境保护署现行废物风险评价模型(3MRA)对某铬渣整治项目进行环境风险评价.模拟了治理前后区域内环境风险情况.分析了污染物暴露途径及危害对象.通过模型对该项目预定处置方法可行性进行了验证.模拟结果显示,在95%受保护对象、95%置信水平条件下,铬渣堆存区域存在显著的环境风险,周边居民致癌风险在10-4数量级,水域生态风险危害商数1.而在对铬渣进行解毒填埋处置后,环境风险将有效降低,验证了此项目处置方法的可行性.

| Abstract: | Multimedia,multipathway and multireceptor risk assessment model(3MRA),a waste risk assessment model currently used by USEPA,was applied to assess the environmental risks of chrome residue management project in a chromic salt factory.During the assessing process,the environmental risks before and after management in this area were simulated;meanwhile the pollutant exposure pathways and the harm sufferers were also analyzed.The feasibility of the scheduled treatment methods was verified by this model.The simu... |
