某河沉积物中铅镉污染分布特征及生态风险评价

摘要

测定某河6个监测点位表层和2个垂直点位沉积物中铅、镉含量,研究其分布特征和主要来源,运用地累积指数和Hakanson潜在生态危害指数对其污染状况进行了评价.%The content of heavy mental lead and cadmium in a river were determined at six monitoring location and two vertical location.The distribution character of heavy mental lead and cadmium and its source were researched,and its state of pollution were assessed by using the geo-acculmulation index and Hakanson potential ecological index.
