Concentrations, Ecological and Health Risk Assessment of Heavy Metals in Surface Water and Sediments of Ogun River in Owode Onirin,
Industrial processes, including scrap yards, can contaminate surface waters with heavy metals, posing a risk to aquatic habitat and human health. Thus, the concentrations, ecological and health risks of heavy metals in surface water and sediment of the Ogun River in Lagos was investigated. Surface water and sediments collected from the Ogun River were analyzed for some physicochemical parameters and heavy metals using standard procedures.
