Abstract
The magnetic susceptibility and the concentrations of Cu, Zn, Pb , Cr and Mn in topsoil samples from Qinghai Lake Area were measured to study their spatial distribution and their correlation in this study. The results show that: (1) Spatial distribution of topsoil magnetic susceptibility has a certain regularity in study area, showing south shore is high, north shore is low; (2) Cu, Zn, Pb and Cr are significantly positively correlated with magnetic susceptibility, while Mn are significantly negatively correlated with it. The spatial distribution of magnetic susceptibility is identical with the concentrations of Cu, Zn, Pb and Cr. However, the spatial variation of magnetic susceptibility is different from the concentrations of Mn. (3) Soil magnetic susceptibility can be used as an effective monitoring means for heavy metal pollution in Qinghai Lake Area soil.
