Assessment of Potential Ecological Risk of Soil Heavy Metals in Songhua River Upstream Jia-Pi-Gou Gold Mine Area

摘要：

　　The ecological risks of seven different soil heavy metals in the Jia-pi-gou gold mine area located in the upstream area of Songhua River were discussed with the method of single and compound factor potential ecological risk index.The results showed that the soils had serious and strong ecological risks of Hg and Cd with the single ecological risk index of seven elements in sample points of gold mine area,the risk index being 464.6 and 140.8,respectively,and slight risks of Cu,Zn,Pb,Cr and Ni with the index were less than Hg and Cd.The risk order of heavy metals was Hg>Cd>Pb>Cu>Ni>Cr>Zn.
