| Abstract: | Based on the data of heavy metals in the sediments of rivers in mining areas in the south-east of Yunnan,the potential ecological risk of heavy metals were analyzed and assessed by using the method of potential ecological risk indices presented by HANKANSON.The results show that the main heavy metals are cadmium and arsenic in the areas,and the potential ecological risk index order of heavy metals in sediments from sampling location A to G is A
