Abstract:
The distribution of heavy metals in landfill leachate contaminated to soil was investigated. Soil samples were collected at different times of the year as well as at various locations and depths in and around the landfill and throughout the contaminated area. The physical and chemical properties of the samples were analyzed. The results indicated that the heavy metals, namely Cd, Cr, Pb, Cu and Zn were significant concentrations in the soil within a radius of 2,000 m from the landfill. The Spearman’s rank correlation coefficient indicated that the appearance of high Cation exchange capacity, clay content and organic matter are statistically correlated with the high heavy metals accumulation. Moreover, the Fe and Mn oxide/oxyhydroxides plays important role in controlling heavy metals sink in soil as pointed out by the Spearman ‘s rank correlation coefficient which corresponding to the soil type, red loess with high iron oxide, in the study area.
