ARM Susceptibility Mapping as a Proxy for Heavy Metals Loads of Soils Monitoring in the Dabaoshan Mine, South China

Under certain circumstances, ARM susceptibility (chi_ARM) can be used as a sensitive proxy in monitoring heavy metals pollution of soils. Strong positive correlation of chi_ARM with Ag, Pb, Cu, Zn and Cr was observed in heavy metals pollution of soils by industrial contamination coming from metal-working factories, mining and traffic pollution. In this study, chi_ARM were measured with 66 samples collected from 22 soil profiles on the Hengshi River Catchments of the Guangdong Dabaoshan Mine, southern China. The result indicates that chi_ARM mapping can be effectively applied for spatial pattern and transfer pathways on chi_ARM load of magnetic minerals in soils. In terms of chi_ARM spatial delineating of magnetic mineral population in soil profiles, heavy metals concentrations of soils will be examined in the local geological and environmental setting.
