Parameters physico-chemical and heavy metals in Pompom River, Kogi State, Nigeria

Donald Peters
The use of rivers for various purpose s ha s re sulted in their deterioration. Water quality involves integrating chemical and biological monitoring methods to evaluate the negative potential human health impact. Water samples from ri ver Pompom in the vicinity of the Nigerian iron ore deposit at I takpe, Nigeria, were analyzed for pH, turbidity, odour, conductivity, total suspended matter, total d issolved solid, biochemical oxygen demand, chemical oxygen demand, Cd, Cu, Ni, Pb and Zn to

Water samples were digested with HNO 3 and Flame Atomic Absorption Spectroscopy technique was used for the determination of concentration level of heavy metals while the physicochemical parameters were determined by gravimetric and titrimetric methods. Comparing the results obtained with Nigeria (Federal Environmental Protection Agency, FEP A) and WHO permissible guidelines for drinking water the concentration of Cu, Ni, Pb and Zn were found to be within safe limits. The pH, TDS and conductivity were found to be within the WHO safe limits of drinking water. Microbiological characteristics and element speciation are recommended for further quality asse ssment in the study area.
