中文摘要:
      选择云南会泽县者海镇矿区重金属污染场地,按不同暴露途径计算土壤中Pb、As、Cd、Zn、Cu、Cr、Hg等金属污染物的风险,并通过风险评价,分析场地内的健康风险水平。结果表明:所有暴露途径中Zn、Cu、 Pb对人体健康的平均风险较小。在居住用地情景下,土壤中Cd的综合致癌风险为2.6×10-5,As的综合致癌风险为3.3×10-4,场地内As和Cd的污染对敏感受体健康的潜在危害较大。
英文摘要:
      The risk of metal pollutants such as Pb, As, Cd, Zn, Cu, Cr, Hg in mining area of Zhehai Town, Huize County, Yunnan Province were calculated according to different exposure pathways. The health risk level was analyzed by risk assessment. The results showed that Zn, Cu and Pb had lower average risk to human health in all exposure pathways. In residential site, the comprehensive carcinogenic risk of Cd and As were 2.6×10-5, 3.3×10-4, respectively. As and Cd pollution in this site were potentially harmful to the health of sensitive receptors.
