摘　　要：依据《建设用地土壤污染风险评估技术导则》(HJ253—2019),分别对三块典型制革场地进行了人体健康风险评估。识别三块场地的Cr(Ⅲ)和Cr(Ⅵ)为场地关注污染物。Ⅰ号场地的鞣制车间和污水处理车间具有致癌风险,分别是限定值的292和135倍。Ⅱ号场地的所有区域均具有一定的致癌风险,其中污泥堆场的致癌风险较高,是限定值的248倍;并且,污泥堆场也具有非致癌危害,为限定值的296倍。Ⅲ号场地中致癌风险和非致癌危害分别达到限定值的841倍和905倍。计算得到的Ⅰ号场地土壤Cr(Ⅵ)的风险控制值为:Cr(Ⅵ)053mg/kg,Ⅱ号和Ⅲ号场地土壤Cr(Ⅵ)的风险控制值为:Cr(Ⅵ)0299mg/kg。对于人体具有健康风险的区域,建议实施必要的场地管控措施,并结合土壤Cr(Ⅵ)风险控制值和国家现行标准进行制革场地土壤的防控和修复。According to the Technical guidelines for risk asssment of soil contamination of land for construction(HJ 25.3-2019),three typical tannery sites were evaluated for human health risks.Identify Cr(II)and Cr(VI)of the three sites as site concern contaminants.The tannery and sewage treatment plants of Site I have carcinogenic risks,which are 2.92 and 1.35 times the limit value respectively.All areas of Site I have certain carcinogenic risk,among which the carcinogenic risk of sludge yard is higher,248 times the limit value.In addition,the sludge yard al-so has a non-carcinogenic hazard,which is 2.96 times the limit value.At Site I,the carcinogenic and non-carcino-genic risks reach 841 and 9.05 times the limits,respectively.The calculated risk control value for soil Cr(VI)of Site I is Cr(VI)0.53 mg/kg,and the calculated risk control value for soil Cr(VI)of Site II and Site II is Cr(VI)0.299 mg/kg.For areas with human health risks,it is recommended to implement necessary site control measures,and com-bine the soil Cr(VI)risk control value and the current national standard to prevent and remediate the soil of the tan-nery sites.
