Distribution pattern of some heavy metals pollutants in the bottom sediment of Ekpan Creek, Warri, Delta State, Nigeria

Ekpan creek was sampled at three selected locations and the samples analysed for some heavy metals to determine the concentration speciation and distribution pattern of the metals. The sediments were obtained specifically at upstream, effluent zone and downstream of the river in the industrial location. The metals 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 studies suggest that some of them are strongly associated indicating a common source for the coupled metals. The main concentration level of bio-available fraction of Pb, Cu, Cd and Zn in bottom sediments along the length of the creek were 28.89 + - 1.05 Mg/kg, 14.54 + - 4.06 Mg/kg, 12.92 Mg/ kg 1.08 Mg/kg and 64.92 + - 3.84 Mg/kg.
