摘要
以君安矿区复垦土壤为调查研究对象,分析了该矿区不同复垦基质的主要重金属污染元素Pb、Cu、Cd和Cr的含量,并采用三步评价法对该矿不同区域复垦土壤的环境质量进行了分析与评价。结果表明:君安矿西区、东区复垦土壤环境质量合格,北区、南区和中区复垦土壤均不符合我国土壤环境质量标准;通过将矿区与全国土壤背景值进行比较可知,矿区复垦土壤未受到重金属Cu的污染,受Cd、Cr的污染较轻,受Pb的污染较严重。该研究可为进一步确定矿区土壤复垦方向提供依据。
Taking the reclaimed soil of Jun’an mining area as the research object,this paper analyzes the heavy metal content of Pb,Cu,Cd and Cr in the reclaimed soil,and evaluates the environmental quality by three-evaluation method.The results show that the environmental quality of the reclaimed soil in western and eastern sections is qualified while the environmental quality in northern,southern and central sections does not meet the environmental quality standards for soil.For the further determination of mine soil’s reclamation direction,the paper compares the pollution elements in this mining area with the national soil background,and finds that there is no copper contamination,a little contamination of Cd and Cr,and a serious contamination of Pd.
