摘要
近年来开展对遗留工业用地的调查与风险评估已变成十分必要的程序,文章采用内梅罗综合污染指数法、单因子污染指数法以及潜在生态危害指数法对某遗留工业用地进行重金属污染状况分析评价。由评价结果可知,单项指数比较高的为As和Cu,Cd和Pb的污染程度相当,四种重金属均处于轻度污染等级,通过对遗留场地的四种重金属E_(Cd)、E_(As)、E_(Cu)、E_(Pb)平均值分析可知,其评价系数均属于小于40的范围,表明该区域内并未受到重金属的污染,不需要进行相关重金属的修复工作。
The investigation and risk assessment for the legacy industrial land that it has become a necessary procedure in recent years.The paper analysis and evaluation of soil heavy metal pollution in a legacy industrial land that use the Nemerow composite index single-factor contaminant index and potential ecological risk index.According to the evaluation results,The As and Cu are relatively high in single index,As the same of the pollution degree of Cd and Pb,The four heavy metals are all in the mild pollution level.Through the analysis of the average values of the E_(Cd)、E_(As)、E_(Cu)、E_(Pb) in the legacy industrial land:All the evaluation coefficients are less than 40,The results show that the industrial land is not polluted by heavy metals,and it is not necessary to do a work for heavy metals soil remediation.
