摘　　要：运用地累积指数法和分级提取评价技术,对辽西钼矿区下游女儿河沉积物中的Cu、Zn和Mo的污染程度进行了评价。结果表明,两者的评价结果存在差异性,地累积指数法在一定程度上过高估计了沉积物中重金属污染的风险,分级提取评价技术科学性更强,建议推广应用。Heavy Metal Pollution of Cu, Zn and Mo were evaluated in the Never River sediments impacted with Mo mining activities in western Liaoning,with Index of Geoaccumulation and Sequential Extraction Procedure. This study indicates that the Index of Geoaccumulation overestimated the degree of heavy metal pollution risk relative to the Sequential Extraction Procedure to some extent. The sequential extraction procedure should be generalized in China because of its scientificity.
