Indication of Magnetic Susceptibility to Heavy Metal Pollution in the Typical Contaminated Areas of Southern Jiangsu Province

Abstract:

Magnetic susceptibility characteristics as well as the relationships between magnetic susceptibility and As, Hg, Cu, Pb, Cd, Cr were investigated in the typical contaminated areas of southern Jiangsu Province.It was found that the correlations between magnetic susceptibility and Cu, Pb were relatively significant, while the correlations between magnetic susceptibility and Cd, As were weak. Heavy metals in soils from industrial wastewater discharge were associated with the magnetic susceptibility, which showed better correlation than other pollution sources.The primary component analysis showed heavy metals in soils from Nanjiao area were mainly the dust from metallic factory , Source of heavy metals in the soils of Ehu area showed the close relationship with the industrial wastewater source in this area.Characteristics of heavy metals in Dingshu area were associated with the source of the mixed wastewater.It is apparent that the different sources will lead to the changes of the correlation between heavy metals and magnetic susceptibility. Generally,the relationship between heavy metal and susceptibility is good in the soils irrigated with industrial wastewater, and metals from the mixed wastewater show a relatively poor correlation with the magnetic susceptibility.
