To understand heavy metal content in soil of rural landfill in Chongqing, samples were collected at 10 sampling sites of different counties. Zn, Cr, Cu, Cd and Pb contents were analyzed, and their pollution degrees were evaluated by single-factor evaluation and index of geoaccumulation. Results displayed that there was no Cr pollution in soil of rural landfill in Chongqing, but Cd pollution was very serious. Pb, Zn and Cu showed spatial difference in different counties. Dispersion degrees of Zn and Pb pollution were lower, and their pollution degrees were also relatively lower. Dispersion degree of Cu pollution was higher, and its pollution degree was also relatively higher. 展开更多
