Warri river, a major river in the Delta region of Nigeria, was sampled at three selected industrial locations and the samples analyzed for some heavy metals by Flame atomic absorption spectrophotometry. The total levels of Fe, Cu, Ba, Pb, Cd, Cr, Ni.and Co in ppm were determined specifically at upstream, effluent zone, and downstream of the river in each industrial location. Fe, Cu and Pb were found to be the most abundant metals in the river. The metal distribution pattern of the river clearly indicates the source of pollution to be land-based and implicates the industries in the adjacent area as the most likely source. Correlation analysis of elemental concentrations suggest that some of them are strongly associated, indicating a common source or chemical similarity for the coupled elements. The values of temp (24.00-27.30 0 c), PH (7.56-7.98), chloride (21.30-159.80mg/l), alkalinity (40.26-97.60mg/l) and suspended solids (0.0008-0.0414mg/l) are also reported.
