| Abstract: | In order to understand the heavy metal pollution of agricultural land around a coal mine in southwest China,eight heavy metal elements of 84 surface soil samples were analyzed,and heavy metal pollution and ecological health risk were evaluated.Results showed that the soil heavy metals in the study area were higher than the background values in Western Chongqing,and the Cd pollution was more obvious.The potential ecological risk index showed that Hg and Cd were the main ecological hazard elements. |
