Abstract

Abstract:

Based on the analysis results of magnetic susceptibility and chemical analysis of 399 topsoil samples, the typical characteristics of the soil magnetic susceptibility of Xinchengzi District in Shenyang have been summarized systematically, and the indication of soil heavy metal pollution by magnetic susceptibility has been studied. The results show that :(1)Magnetic susceptibility is diverse among various soil types，and the mean of brown soil is high because of human influence. Magnetic susceptibility of different accumulation is various.disparate demands of crops for elements result in the difference of magnetic susceptibility.(2)Soil magnetic susceptibility has distinct positive correlation with such heavy metal elements as cadmium，lead，mercury，copper and zinc. It also has negative correlation with pH of soil that can reflect soil acidification situation. So magnetic susceptibility may be used as better indicators for soil pollution.(3)Polluted zone is plotted out conveniently and rapidly via magnetic susceptibility.

Key words: magnetic susceptibility, soil, heavy metal elements, Shenyang
