Abstract

This study evaluated the Impact of oil pollution on Kolo Creek wetlands by examining the concentration of hydrocarbons and heavy metals in the ecosystem. Standard methods for investigating environmental quality were applied in this study using surface water, sediments and biota as proxies. Three sites (A, B, C) were chosen for this study. Significant pĤ and high regional salinity values, especially in Site B, were found. Also, PAHs, BTEX and most metals were absent in the water column apart from cadmium which occurred above acceptable standards for both aquatic ecosystem and livestock feeding. In the sediments, BTEX were not detected while low concentrations of naphthalene (0.01 and 0.1 mg/L) were found. Lead, zinc, chromium and nickel had low levels although zinc showed a higher level in the site directly impacted by oil spill.
