ABSTRACT

The study was designed to investigate the comparative levels of trace metal concentrations in water and sediments of four streams around Ibadan metropolis. Samples were analyzed for seven heavy metals using atomic absorption spectrophometer. The results shows that the concentration of cadmium varied from (0.0015-0.0140ppm), Iron (0.88-55.843ppm) chromium (0.005-0.0718ppm), zinc (0.024-0.0113ppm), lead (0.005-5.415ppm), copper (0.094-0.0053ppm), nickel, (0.004-0.145pppm) for all the four streams sampled, while for the sediments the following results were obtained. Cadmium concentration varies from (0.5-4.5ppm,) Iron (5993-36693ppm), chromium (6.000-100ppm) zinc (11.9-252.62ppm,) lead (3.713-96.08ppm), copper (11.9-249.6ppm,) Nickel (5.00-26.88ppm). The results of the analysis showed that all metallic ion concentration were above the world health organization standard for sediments except for cadmium, chromium and Nickel where it was lower in the water sample which poses health hazard for users.
