| Distribution of Pb in Soils of the Jinding Pb-Zn Deposit，Lanping，Yunnan Province |
| The speciation of Pb in soils of the Jinding Pb-Zn deposit was analyzed by sequential extraction procedure, and the distribution and speciation variability of Pb were studied by geostatistics. The results show that most soils in Jinding area are contaminated by Pb. According to the soil environmental quality standard(ClassⅢ), the median content of Pb is 1.77 times higher, while the mean content is 19 times higher. Distribution of Pb shows that the pollutants are influenced by the distribution of the deposit, the terrain variation, the mining activity, and the rivers, and that the water-soluble faction of Pb is especially affected by the distribution of plants and rivers. The general trend of Pb in soils is residual>carbonate>Fe-Mn oxide>organic>exchangeable>water-soluble. As the available fraction of Pb is rather high in Lanping area, there exists considerable Potential danger in Lanping area and Beijiang river valley. |
