%X The pollution of aquatic ecosystems by heavy metals has assumed serious proportion due to their toxicity and accumulative behavior. Various hydrochemical parameters of river water (pH, total dissolved solid, sulfate, nitrate, calcium, magnesium) in these rivers around Ikorodu were studied in 2005. The main aim of this study is to assess the impact of effluent discharge on the water quality of rivers Majidun, Molatori and Ibeshe. Physiochemical parameters including pH, total solids, total dissolved solids, alkalinity and nitrate were used for the evaluation of effluent discharge on the rivers. The results were compared with standard permissible limits. The concentrations of cadmium, chromium, copper, iron, lead, manganese and magnesium were also determined in the water samples. Results obtained show the pollution tendencies of the rivers. This was attributed to high levels of lead, chromium, and cadmium. The results also showed that with the continuous discharge of industrial effluents, pollution of the rivers by heavy metals is likely to have adverse effects.
