The assessment of heavy metals levels in the soil from the Oji coal ash dump was evaluated. Concentration levels of the thirteen metals Fe, Mn, Ni, Pb, Cd, Cu, Cr, Co, Zn, As, Mo, Se and Hg in the soil samples were determined using Atomic Absorption Spectrometer (AAS) Varian 240 AA. The soil samples were subjected to Speciation analysis using the modified Tessier Sequential Extraction Protocol (SEP).The trend for percentage bio-available metals in the soil of the study area was.............................................................................
