Abstract
The content of six heavy metals including Cd,As,Cu,Pb,Cr and Zn in the sediment of Shijing River was detected.By using single factor index method and Hakanson's ecological risk index method,six heavy metals in the sediment samples were analyzed and their pollution degree and potential ecological risk were evaluated.The results showed that the prominent pollution factor of Shijing River was Cu and the potential ecological risk was moderate.And the ecological risk degree of each pollution element in order was as follows: CdCuAsPbCrZn.
