A review of soil heavy metal pollution from mines in China: pollution and health risk assessment.

Contaminated sites will restrict regional development, especially the residential area development as the contamination can pose long-term adverse health risks. Western Suzhou, where three mining areas are located, is a rapid urbanization area in Suzhou City, Jiangsu Province, the People’s Republic of China. This urbanization has been pushing into the mining areas. This study aims to assess the heavy metal contamination (including Cu, Zn, Pb, Cd, Hg, Cr, As, and Ni) and identifies the contaminated sites in Western Suzhou. Fifty soil samples and 34 road dust samples in Western Suzhou including a closed mine (A1), a mineral concentration plant (A2), and a newly opened mine (A3) were collected and analyzed. The geo-accumulation (I
 geo) methodology, principal component analysis (PCA), spatial interpolation, and health risk assessment were employed for evaluation. The contamination levels are ranked in the orders of Cd > Pb > Zn > Cu > As > Hg > Ni > Cr for soils and Cd > Pb > Zn > Cu > As > Ni > Hg > Cr for road dusts. The concentrations of heavy metals in the road dusts are generally higher than those in soils. Copper, Zn, Pb, Cd, and As are the main contaminants and mainly due to mining activities. Lead, Cd, and As in the soils and road dusts in the three mining areas pose high non-carcinogenic risk to children. Spatial analysis shows that the soils and road dusts in areas A1 and A2 have the highest concentrations of heavy metals, followed by area A3, where only the road dust exhibits high concentrations. The results show that there exist contaminated sites in areas A1 and A2 and remediation measures are urgently needed.
