摘要
鉴于矿区生态环境破坏和经济社会的矛盾日益突出,通过实地调查与室内分析,采用潜在因子法,利用危害系数Eit和风险指数RI等定量诊断工具对淮南某重金属污染典型矿区进行了潜在生态风险评价.评价结果表明:4个区重金属综合污染程度顺序依次为钙镁化工厂区(C)>建筑垃圾和化工废料混合区(A)>矸石堆放区(B)>矸石与建筑垃圾混合堆放区(D).
The contradiction between the ecological environment in coal mine and social development is becoming increasingly conspicuous. Through field investigation and sampling analysis, studied the heavy metal content status of soil in a typical coal mine district in Huainan, China. Quantitative diagnostic tools, toxic-response factor (Et^i) and potential ecological risk index (RI) were used to evaluate the contamination situation of various heavy metals. The results show that the descending order of the composite contaminated grade of heavy metals in soil is district C 〉 district A 〉 district B 〉 district D.
