dc.description.abstractHeavy metals concentrations of water and sediments in the oil exploration zone of the Qua Iboe river estuary in Nigeria was investigated by analysing the samples for their Cd, Ni, Pb and V concentrations using atomic absorption spectrophotometry. The results obtained indicated that the heavy metals concentrations of the samples were below the WHO pollution limits with maximum values of 0.003 mg/l for Cd, 0.143 mg/l for Ni, 0.040 mg/l for Pb and 0.102 mg/l for V in the water samples. Concentrations of the heavy metals in the sediment were significantly higher than the values in the water samples (P < 0.05), with positive correlation between the levels of the heavy metals in the water and the sediment, except for Pb. However, there is tendency of elevation in the concentrations of the studied heavy metals over a period of time, since oil exploration has the potential of increasing the concentrations of heavy metals in the estuary. The authors recommended the control of industrial activities within the coastal area.en_US
