Abstract
[Objective]To evaluate the potential ecological risk of heavy metals in river sediment around Feng County.[Method]Based on the data of heavy metals in the surface sediments from three rivers near gold mine, the potential ecological risk of heavy metals were analyzed and assessed by using the method of potential ecological risk indices presented by Hakanson.[Result]The results showed that the contamination of surface sediments from rivers near gold mine was slight, and the main factor caused ecological hazard was mercury, cadmium and copper following by lead and arsenic.The comprehensive index of potential ecological risk showed the contamination level of surface sediments was slight ecological risk,the harm degree of heavy metal pollution in Santaishan gold mine,Pangjiahe and Xiaoyuhe decreased successively.[Conclusion]The study can provide reference for the treatment of heavy metal pollution in the surrounding rivers of mining area.关键词
