Risk Appraisal of Itagunmodi Mining Site for Heavy Metals
Abstract
Heavy metal contamination of agricultural soils and crops surrounding the mining areas is a serious
environmental problem in many countries including Nigeria. Mining and smelting operations are important
causes of heavy metal contamination in the environment. The pollution characteristics of Cu, Ni, Cd, Cr,
Zn and Fe in goldmine tailing were studied. The results indicate that the contamination degree followed
the sequence of 5>1>3>2>4. The concentrations of Cu, Zn Ni and Cr in the soil were low, so their potential
ecological risks were far lower than other heavy metals and exerted no potential harm to environment.
