摘　　要：土壤重金属污染评估是土壤质量管理及生态风险管控的重要内容,也是饮用水安全管控的重点之一。论文通过对浙江省范围内93个水源地周边土壤样品采集,测定其中的8种重金属(镉、汞、砷、铅、铬、铜、锌和镍)含量。采用单因子指数和Hankanson潜在生态风险指数法对土壤重金属污染进行评估,并采用多元统计分析方法分析重金属的可能来源。结果表明,研究区域土壤质量总体较好,整体污染水平和生态风险均处于较低水平。Soil heavy metal pollution assessment is important in soil quality and ecological risk management,especially for the soil environment surrounding potable water resource.The concentrations of eight heavy metals including Cd,Hg,As,Pb,Cr,Cu,Zn and Ni in soils surrounding 93 potable water sources in Zhejiang Province were sampled and analyzed.The pollution level and ecological risk were evaluated with single factor index and Hankanson index.Multivariate statistical analysis was adopted to ascertain the source of heavy metal.The result showed that the quality of soil in study area overall was good,with low level of pollution and ecological risk.
