上海某典型工业地块土壤中特征污染物铜、汞、钴重金属污染健康风险评价

Health Risk Assessment of Heavy Metal Pollution of Characteristic Pollutants Copper, Mercury and Cobalt in Soil of a Typical Industrial Plot in Shanghai

摘要: 以上海市某金属表面加工及热处理企业地块中特征污染物铜、汞、钴为研究对象，对地块内土壤中超标污染物铜(浓度：3190 mg/kg)、汞(浓度：13.6 mg/kg)和钴(浓度：69.5 mg/kg)进行风险评估。初步调查识别关注污染物，后续进行进一步详查和风险评估。经过污染危害识别、暴露评估和毒性评估、风险表征、确定修复目标值等评估流程，并结合理化参数分析得到评估结果。风险评估结果表明：特征污染物铜、汞、钴对于潜在暴露人群风险的健康风险超过了可接受范围。

Abstract: Taking the characteristic pollutants copper, mercury and cobalt in the plot of a metal surface processing and heat treatment enterprise in Shanghai as the research object, the risk assessment was carried out on the excessive pollutants copper (concentration: 3190 mg/kg), mercury (concentration: 13.6 mg/kg) and cobalt (concentration: 69.5 mg/kg) in the soil in the plot. The pollutants of concern are identified through preliminary investigation, and further detailed investigation and risk assessment are carried out later. Through the assessment processes of pollution hazard identification, exposure assessment and toxicity assessment, risk characterization, determination of repair target value, and the assessment results of rationalization parameter analysis. The risk assessment results show that the health risks of the concerned characteristic pollutants copper, mercury and cobalt to the potential exposed population exceed the acceptable range.
