以江西某湿法冶炼在产企业场地为例,对场地内土壤进行采样调查,分析场地内土壤重金属污染种类和污染程度;运用污染场地健康与环境风险评估(HERA Version 1.1)软件进行风险评估,评价特征污染物对人群的健康风险。调查评估表明,场地内局...以江西某湿法冶炼在产企业场地为例,对场地内土壤进行采样调查,分析场地内土壤重金属污染种类和污染程度;运用污染场地健康与环境风险评估(HERA Version 1.1)软件进行风险评估,评价特征污染物对人群的健康风险。调查评估表明,场地内局部土壤存在重金属镉污染;受污染土壤中镉的非致癌危害商超过1,非致癌危害为不可接受水平。通过计算,场地内关注污染物镉的土壤风险控制值为12.1mg/kg。展开更多
本研究以湖北省某防水材料生产企业为例,探讨了如何开展在产企业的土壤污染状况调查和风险评估工作。风险评估结论表明,该企业厂区范围内土壤存在石油烃(C10~C40)超标,其对于潜在暴露人群的健康风险水平超过了可接受范围,需要开展污染...本研究以湖北省某防水材料生产企业为例,探讨了如何开展在产企业的土壤污染状况调查和风险评估工作。风险评估结论表明,该企业厂区范围内土壤存在石油烃(C10~C40)超标,其对于潜在暴露人群的健康风险水平超过了可接受范围,需要开展污染土壤修复或风险管控工作。建议石油烃(C10~C40)的修复目标值为4500 mg/kg,扣除叠加部分后的修复面积为1970 m2,需修复污染土方量约2041.5 m3,最大污染深度为1.5 m。This study takes a waterproof material production enterprise in Hubei Province as an example to explore how to carry out soil pollution status investigation and risk assessment work in production enterprises. The risk assessment conclusion indicates that there are petroleum hydrocarbons (C10~C40) exceeding the standard in the soil within the factory area of the enterprise, and the health risk level to potentially exposed populations exceeds the acceptable range. Therefore, contaminated soil remediation or risk control work needs to be carried out. The recommended remediation target value for petroleum hydrocarbons (C10~C40) is 4500 mg/kg. The restoration area after deducting the overlapping part is 1970 m2. The amount of contaminated soil to be remediated is approximately 2041.5 m3, and the maximum pollution depth is 1.5 m.展开更多
