Title: Evaluation on the Pollution of Heavy Metal in Sediments of Qinhuai River
Abstract: In this paper,the content of six kinds of heavy metals,copper(Cu),lead(Pb),zinc(Zn),chromium(Cr),cadmium(Cd) and nickel(Ni),in sediments of the Qinhuai River was analyzed.The degree of pollution was evaluated by the Index of Geo-accumulation and the Index of the Potential Ecological Rick.The degree of heavy metals pollution was identified in the study as follows: PbCuCr Zn;pollution by Pb ranked severe and that by Cu,medium-severe;and that by Zn and Cr,medium,while Cd and Ni were not contaminated.Generally,the Qinhuai River is at a medium potential ecological risk.Among the analyzed heavy metals,Pb and Cd exhibited the highest pollution degree.
