摘　　要：在某项土壤重金属污染风险评价工作中,工作小组选取了浙江某地24km^(2)的耕地土壤作为监测样本和研究对象,采用钻孔取样技术,依次检测了地表下30m的土壤中所含的Cr^(6+)、Pb、As和Hg等重金属。同时,采用了潜在生态风险指数评价法、内梅罗指数评价法、地积累指数评价法和单项污染指数评价法对土壤的重金属污染状况展开了全面性评价。本文将简单分析土壤重金属污染风险评价方法,希望能为耕地环境保护工作提供借鉴。In a certain soil heavy metal pollution risk assessment work,the working group selected 24 square kilometers of cultivated soil in a certain area of Zhejiang as the monitoring sample and research object,and used borehole sampling technology to sequentially detect the soil 30 meters below the surface heavy metals such as Cr^(6+),Pb,As and Hg contained in it.At the same time,the potential ecological risk index evaluation method,Nemeiro index evaluation method,geo-accumulation index evaluation method and single pollution index evaluation method were used to comprehensively evaluate the heavy metal pollution of the soil.This article will briefly analyze the risk assessment methods of soil heavy metal pollution,hoping to provide a reference for the environmental protection of cultivated land.
