Ni>Zn>Mn>Cr>Pb>Cd>Cu>Co. The mean concentration levels of all the heavy metals were lower than mean background values except Cu and Fe during the dry season. The results of the study revealed that the soil of the Odagbo is polluted by all the tested heavy metals based on the calculated PI and I-geo for the heavy metals. The PI was mostly 1≤ PI ≤ 2(moderate pollution) for all the depths except for the elevated case of copper thus indicating practically low to moderate contamination. The I-geo was mostly less than 0 at all the depths except for the elevated cases of copper, iron and zinc during the dry season and Copper and Iron during the wet season thus indicating uncontaminated condition. In conclusion, the data obtained from the study demonstrated that the distribution of metal concentration in the study area when compared to the control site was largely influenced by anthropogenic activities particular from the coal mining site.]]>
