  In this study, a non-destructive analytical techniques (Energy dispersive X-Ray fluorescence) was used to analyze the concentration of seven heavy metals (Pb, Cr, As, Ni, Cd, Cu and Zn) in tin mine tailing from mining and control sites in Rim, Sharubutu and environs. The physicochemical results showed the pH for S1 and S2 from the mining and control sites were (5.31 and 4.97) and (6.32 and 5.71) respectively indicting that the mine sites is more acidic than the control sites. While their bulk density and electrical conductivity was good for planting. The concentration of the heavy metals were within the maximum permissible limits except for Pb and As in mining and control sites of range (270-300) mg/kg and (60-80) mg/kg, which are above the permissible limits (80 mg/kg and 0.07 mg/kg) respectively. This could be attributed to the mining activities and atmos.. Read More»
