摘    要:应用综合污染评价法和Hakanson潜在生态风险指数法对包钢尾矿坝及周边的表层土壤中(0~20 cm)重金属元素铅、锌、铜、砷和铬单独与复合污染特征进行研究,定量测定了包钢尾矿坝的潜在生态风险程度、主要污染因子和潜在生态风险因子。结果表明:包钢尾矿坝及周边土壤受到不同程度的重金属污染,各重金属潜在生态风险参数由高至低顺序为Pb>As>Cu>Cr>Zn,Pb的潜在污染风险参数最高,是主要潜在生态风险因子,其次是As。

关 键 词:尾矿坝  重金属  潜在生态风险评价  复合污染

Abstract:Individual and combined pollution characteristics of heavy metal elements( Pb, Zn, Cu, As and Cr) of surface soil(0 ~ 20 cm) in Baosteel Group Tailing Dam and its neighboring regions were investigated by utilizing Combined Pollution Assessment Method(CPAM) , Hakanson Latent Ecological Risk Index Method(HLERIM) and quantitative determination of latent ecological risk degree.The key pollutant and latent ecological risk factor was carried out.The results indicated that the heavy metal pollution degree varies in Baosteel Group Tailing Dam and its neighboring regions.It also showed the latent ecological risk indexes can be seen as followings from high to low:Pb, As, Cu, Cr ,Zn.Among them, the pollution risk index of Pb is the highest and then As.
Keywords:Tailing Dam  Heavy metal  Latent ecological risk assessment  Combined pollution
