Trace Elements Geochemistry of Soil-Plant System in Puxiong Lead-Zinc Mining Area, Yunnan, China

Abstract:

This study aims to obtain an overview of trace elements concentrations in rocks, soils and plants from Puxiong lead-zinc mining area in Yunnan, China, and analyze the connection as well. Concentrations of Ba, Cd, Co, Cu, Mn, Pb, Zn, As, Sb, Hg, Sn, Ni and Sr among soils, rocks and three dominant plants in mining area, transition area and background were measured. Ratio parameter, bioconcentration factors (BF) and Pearson's correlation coefficients were used to analyze the relationship between these elements in different feature. The results indicate that rocks, soils and plants samples are all characterized by high concentrations of Pb, Zn and other associated elements in Puxiong lead-zinc mining area. Geochemistry of trace elements concentrations from rocks to soils, then to plants presents obvious characters of inheritance and variability. Whats more, three dominant plants are same in high concentration of Mn and low concentration of Cd, Hg, Co, but are huge different in bio-concentration factors.
