| Abstract: |
| The problem of staple industrial solid wastes is particularly acute. To fully manage these solid wastes, it is necessary to carry out research the evaluation for pollution of heavy metals in soils. The distribution characteristics of heavy metals (Cd, As, Zn, Pb, Cu, Hg, Cr, Ni) in soils of copper tailing dam in Xinping are described in this study. The authors evaluated the influence of the pollution characteristics of heavy metals with three different methods (the single factor index, the Nemerow integrated index and the potential ecological risk index). The results showed that the pollution level of all the monitoring points are the safety. For the potential ecological risk index method, the RI value of this area is 207.39 and indicatives middle ecological harm. In summary, the surrounding soil of Xinping of yunnan copper tailings was protected well. The heavy metal concentrations of soils conformed with the environmental quality standard for soils. But few point had on the potential ecological risk. Thus, the region needs further monitoring, controlling and prevention. |
