Journal Title:Journal of Environmental Issues and Agriculture in Developing Countries
This study examined notable points of effluent discharge sources of the Warri River and their level of toxicity. Nine locations were chosen, seven of them were points of effluent discharge, while two are the terminals, which served as control. Water/effluents were collected quarterly for two years in 250m/s sampling bottles. There was significant difference in physicochemical characteristics and heavy metals between the locations. Temperature, COD, TDS, pH as well as five heavy metals Fe, Pb, Cr, Ni and Cd in effluents obtained at all stations except the control points, exceeded specified permissible limit by statutory bodies. This implies that these effluents were not treated. The government, regulatory bodies and indeed all stakeholders must sit up in order to safeguard the aquatic life, resources and human population that depend on the river for food, water and recreation and survival.
