Abstract: Concentration and chemical species analyses of heavy metals (Mn, Pb, Zn, Cu and Cd) in the soils were carried out, which were collected from different areas in Guiping manganese mine, Guangxi. The results showed that the six heavy metal elements in the soils exceeded the soil background contents, and Mn and Cd were the main pollutants. Mn was mainly in form of Fe-Mn oxides, which accounted for 73.11%~92.67% of the total. Pb was mainly in forms of exchangeable, Fe-Mn oxides and residual, which accounted for 28.96%~46.59%, 15.74%~38.62% and 18.72%~36.94% of the total respectively. Speciation distributions of Zn and Cu were similar. Both of them were in forms of residual, accounting for 61.75%~80.01% and 62.75%~85.67% respectively. As the second important form, it was dominated by Fe-Mn oxides phase, and accounted for 7.34%~18.68% and 8.17%~22.93% respectively. Cr in the soils was dominated by residual, and accounted for 74.89%~85.87%. Species distribution of Cd was relatively uniform with the largest proportion of exchangeable form, which accounted for 28.24%~36.00%. According to comprehensive analysis of the results of heavy metal concentration and chemical species, it was found that Mn and Cd have greater potential impact on the ecosystem of Guiping manganese mine.
