Abstract

Analysis of total metal concentrations and speciation of Lead (Pb), Zinc (Zn), Chromium (Cr), Manganese (Mn), Copper (Cu), and Iron (Fe) were carried out on soil samples from West of Mines, Tudun Wada and Dadin Kowa in Jos, Plateau state. Results show that zinc has the highest concentration of total metals while lead was not detected at all. Speciation results show an average of 4.47% of total metals in the exchangeable fraction, 9.95% in the carbonate fraction with chromium and copper not detected, 28.47% in the Fe-Mn oxides fraction with manganese being predominant, 8.44% in the organic fraction and 46.86% in the residual. The general pattern was that the bulk of the trace’s metals studied were present in the non-mobile, slightly or non-reactive, poorly or non-available forms.
