| 中文摘要: |
| 以湖北某含砷金矿污染场地为例，依据《污染场地风险评估技术导则》（HJ 25.3—2014），对其周边土壤和地下水中砷元素进行健康风险评价，结果表明：该金矿周边土壤和地下水中砷分别通过经口摄入土壤、皮肤接触土壤和吸入土壤颗粒物、饮用地下水4种暴露途径的致癌风险均超过可接受风险水平（10-6），对周边居民造成潜在危害。计算得到经口摄入、皮肤接触和吸入途径基于致癌效应的土壤风险控制值分别为1.6 mg/kg、9.3 mg/kg和12.1 mg/kg，应予以重视，并建议对矿山进行综合治理和目标值修复。 |
| 英文摘要: |
| The health risks of arsenic in soil and groundwater near an arsenic bearing gold ore in Hubei province was investigated in this work,which was carried out according to the state environmental protection department of contaminated sites risk assessment technology guideline(HJ 25.3—2014).The results indicates that the carcinogenic risk of the four paths including oral intake of soil and underground water,skin contact and inhalation of soil particles exceed the acceptable risk level(10-6),which could cause potential damage to the people.The calculated risk control value for the oral intake of soil,skin contact and inhalation of soil particles are 1.6 mg/kg、9.3 mg/kg and 12.1 mg/kg,respectively.The results indicated that attention should be paid to the mine comprehensive treatment and target remediation. |
