摘要
以某搬迁或撤离的金属加工厂为例,对其遗留的地块进行场地环境调查及其人群健康风险评估。结合调查评估的土壤及地下水检测数据,最终确定重金属镉和锑为本场地关注污染物。根据健康风险评估模型,结果发现锑和镉的非致癌风险超出人体正常风险水平。通过计算,关注污染物锑的风险控制值为5.7mg/kg,镉的风险控制值为11.9mg/kg,进而得出本场地目标修复值,为后续场地环境修复做出理论基础。
Site environmental survey and health risk assessment has been carried out a former relocation site of metal processing.According to soil and groundwater testing data,cadmium and antimony were considered as the concerning contaminant.According to health risk assessment model,it was found that the non-carcinogenic risk of cadmium and antimony were higher than the normal acceptable level of human body.Basing on model calculation formula,the value risk control of antimony was 5.7mg/kg,the value risk control of cadmium was 11.9mg/kg.Besides,target repair value was determined so that it was to lay the groundwork for the environmental repair theory.
