Abstract:Based on the data of magnetic parameters and chemical analyses of 255 samples (185 from surface soils and other from 4 soil profiles), the distributions of soil magnetic susceptibility, heavy metal element contents,their origins and correlation were studied in Huludao City. The result revealed that: ①the magnetic susceptibility of the surface soils had obvious divergence, some were higher than those of common brown soil, but their basic physical and chemical properties were still within the normal ranges, thus, it suggested that the magnetic susceptibility may be promoted by others factors. ②both the magnetic susceptibility and heavy metal element contents decreased downwards in soil profiles, sharming the same vertical variation tendency. ③there were extremely significant correlations between the magnetic susceptibility and the contents of Pb, Zn, Hg, and Ni, significant correlation between the magnetic susceptibility and the contents of Cu. In Pb-polluted area, there was extremely significant correlations between the magnetic susceptibility and Pb content, but no correlation in non-Pb polluted area, it effectively proved that Pb may increase the magnetic susceptibility.
