 en Seasonal Variation of Cd, Ni, Cu and Pb in Catfish, Sediment and Water Samples from Ipo Stream in Ikwerre District of Rivers State, Nigeria.

Abstract

The variation of some heavy metals Cd, Ni, Cu and Pb was conducted on sediment, cat fish and water samples from four stations in Ipo stream in dry and wet seasons. Atomic Absorption Spectrophotometry model 3700 was used to analyzed the samples The result revealed that the average metal concentrations in sediment in both seasons was in the order Pb > Cu >Ni > Cd which were 25.73µg/g, 18.48µg/g, 2.91µg/g and 1.35µg/g respectively. In fish sample the metals also occurred in the order Pb ,Cu , Ni and Cd which were 24.14µg/g ,17.85µg/g, 2.79µg/g and1.15µg/g respectively, while in the water sample similar trend of heavy metals concentrations also occurred which were 23.32µg/l for Pb,17.32µg/l for Cu, 2.42µg/l Ni and1.15µg/l for Cd respectively. These values were below the established standard for aquatic environment by W.H.O and FAO. The result indicated that the consumer of fish and water from the stream is not at risk of being poison by these metals. @ JASEM
