ABSTRACT
Sediment samples were collected through the purposive sampling method from various streams in Akpabuyo L.G.A, ten sample location were selected. The concentration and areal distribution of selected metals (Fe, Zn, Mn, Cr, Ni, Co, Cu, Cd, Pb) in the sediments of Akpabuyo streams .Geo-accumulation index have been calculated to assess whether the concentrations observed represent background or contamination levels. It proves that the choice of the background plays an important role in the interpretation of the geo-chemical data. It is concluded that the selected streams in Akpabuyo is uncontaminated except a metal (Cd) which it i-geo value is 1 which means it is moderately/uncontaminated.
