摘要

Surface water and sediments collected from three stations along Qua Iboe Estuary, Niger Delta between January and June 2013 were analyzed for Iron (Fe), Zinc (Zn), Lead (Pb) and Cadmium (Cd). The trace metal concentrations (mg/L) in surface water were 0.08, 0.17, 0.01, 0.004 for Fe, Zn, Pb and Cd, respectively and 0.59, 0.33, 0.04 and 0.02 mg/kg in sediments respectively for the same metals. There were significant differences (p0.05). Positive significant correlations (p<0.05) exist between the metals in sediments which revealed their co-accumulation potentials. Trace metal concentrations in water and sediment were below the maximum permissible level recommended by national and international standards except for lead in water. Thus Qua Iboe estuary is relatively suitable for fish production and domestic use despite effluent discharges into the estuary.
