Abstract

This study attempts to investigate and compare the vertical migrations of pH, CEC and heavy metals (Pb, Cu, Fe, Cd, Mn,) in automobile and domestic dumpsites soils located in Ilaro, Ogun State Nigeria. Three soil samples each were collected from three different automobile dumpsite (SA1,SA2 SA3) and domestic dumpsite (SD1, SD2, SD3) and the control soil. The pH of the soil samples were determined to evaluate the effect of pH on the metal concentration. The pH values for the automobile and domestic dumpsite ranged from 5.3 to 7.3 with the mean values of 6.46±0.71 and 6.1 to 8.1 with mean values of 7.06±0.69 respectively, indicating neutrality to slightly acidity of soil samples. The CEC ranged from 6.7 to 9.0meq/100g and 7.6 to 9.9meq/100g for both automobile and domestic dumpsite respectively. The vertical distribution of the heavy metals showed that the metals were higher at the top soils than the sub soils and bottom soils for both dumpsites. The mean concentration of the metals in the both sites were in the order>Mn>Pb>Cu>Cd. All the values obtained generally indicated that the soils in all the sites were contaminated with heavy metals. However the metal concentration levels found in this study do not pose any health risk, except for Mn which is above the WHO limit.
