title: Risk Analysis of Metals in Soil from a Restored Coal Mining Area.
abstract: This study was conducted to evaluate ecological impacts of metals in soil from the restored Panyi coal mining area of China. Zn, Cr, Ni, Pb and Cd had significantly accumulated in the studied soil compared with regional background values (p<0.05). Geo-accumulation indices indicate that the soil was at low risk for Cu, Zn, Ni and Pb contamination, while a low to moderate risk for Cr and Cd contamination existed. The ecological impact of all the selected metals was identified by ecological soil screening levels, apart from Cr, the impact of which was determined based on Dutch Target and Intervention Values. Results suggest that plants may be significantly affected by Ni, the avian population by Zn, Pb and Cd, while mammals are possibly influenced by Cd.
