ASSESSMENTS OF HEAVY METAL CONTAMINATION IN SOILS FROM SELECTED SOLID WASTE DUMPSITES OF KAFANCHAN METROPOLIS, KADUNA STATE, NIGERIA
Assessment of heavy metal contamination in soil from selected solid waste dumpsites in Kafanchan metropolis of Kaduna State, Nigeria, were determined and compared with control soil using standard analytical methods. The results, showed that; Heavy metals (Zn, Mn, Cu, Ni, Cd & Pb) mean- concentration (mg/kg) from the solid waste dumpsites were; 1095.4, 843.7, 124.0 32.7, 1.5 & 312.0 respectively. While, the concentrations obtained from the control site for, Zn, Mn, Cu, Ni, Cd & Pb were; 674.8, 941.7, 16.4, 39.4, 0.8 & 119.8 respectively. The trend of the heavy metals pollution status from the solid waste dumpsites, were; Cu > Pb > Cd > Zn > Mn > Ni. ANOVA at P > 0.05 showed that, there was no significant difference in the concentrations of Mn, Cu & Cd, while, the concentrations of Zn, Ni & Pb were significantly different.
