Abstract
The levels of Pb, Cr, Ni Zn, Fe,Cu, Co, Mn, Cd and Hg were determined in
water, Sediment and Fish Samples taken monthly for six months from march 2002 –
August 2002, from the Southern basin of Kainji Lake and below the dam (Jebba
Lake), in order to determine the pollution status of the Lake and the impact of the
hydro-power plant as per heavy metal discharge. Flame AAS and EDXRFS
techniques were used for the analysis and both techniques indicate the order of
relative abundance as Fe > Mn > Cr > Pb > Co > Ni > Cu > Zn > Cd > Hg > in water;
Fe > Mn > Zn > Ni > Co > Cr > Cu > Pb > Cd > Hg in sediments; and Fe, Zn > Mn >
Cu > Ni > Co > Cr > Pb > Cd > Hg in fish.
The level of these metals in all the samples were within the tolerable and
internationally acceptable limits. This implies that the Lake is safe. The results also
do not show the hydro-power plant as a major source of these metals in the Lakes.
