Characteristics of heavy metals in soils under different land uses in a typical karst area,Southwest China
This study investigated the distribution of six pollutant elements(As,Cr,Cu,Pb,Zn and Cd),and their relationship with SOC in five soil profiles in Puding area.Results showed that the mean concentrations of Cr,Cu,Zn and As were lower than the background values(BV)in Guizhou Province,respectively,while the mean concentrations of Cd and Pb exceeded the BV.The concentrations of Cr,Cu,As and Zn in the soils from all the land use types were significantly negatively correlated with SOC contents,suggesting that these heavy metals were influenced by soil organic matter.Geochemical approach confirms the anthropogenic influence of heavy metals pollution in the soils,so it may serve to undertake and design effective strategies and remedial measures to prevent further deterioration of the soils in the near future.
