The Magnetic Susceptibility Characteristic of Urban Soil and Its Environmental Significance

摘要: 研究了南京城市土壤磁化率特征及其与土壤重金属全量、有效态含量及化率的关系。结果表明，城市土壤磁化率平均值大于非城区自然土壤、，而频率磁化率平均值小于非城区自然土壤。土壤磁化率测定可望为监测城市土壤Cu、Zn、Pb的污染状况提供一种简单、快速的手段。

Abstract: The magnetic susceptibility and its relationship with the total content, DTPA extractable content and activity index of heavy metals of urban soils in Nanjing city were studied. The results showed that the magnetic susceptibility of urban soil was higher, and the frequency-dependent susceptibility was lower as compared with those of natural soil. The measurement of magnetic susceptibility provided a simple, quick means for monitoring the pollution status of Cu, Zn, Pb in urban soils.
