The pH of the soil ranged from 5.04 to 6.56d ecreasing with the increase of the distance from the pit. Pb was the most abundant of the four heavy metal sassessed with values ranging from 568 mg/kg to 29,491 mg/kg. Compared to the control, the total heavy metal content was 29.2 times greater at the pit region and 13.5 times greater at distance 30 meters away from the pit.The pH of the soil was negatively correlated with the heavy metal content (Table 3). There were significant positive correlation between Pb, Zn, Cd, Cu and the total heavy metals at P≤0.05. Soil heavy metals concentrations significantly decreased with the increase of the distance from the pit
