Abstract: The pollution of aquatic ecosystems by heavy metals is an important environmental problem as heavy metals constitute some of the most hazardous substances that can bioaccumulate in various biotic systems. This study was aimed at assessing the levels of some heavy metals (Lead, Cadmium, Chromium and Copper) in water, sediment and fish samples from Kpata River in Lokoja metropolis, Kogi State. A total of three samples each of water, sediment, fishes (Clarias garipienus and Oreochromis niloticus) were collected and analyzed for heavy metals using Atomic Absorption Spectrophotometer (AAS). Data obtained were subjected to statistical evaluation using simple statistics. Parameters evaluated were grand mean, standard deviation and coefficient of variance percentage. Result showed that concentration of Lead in the different tissues of the Catfish were higher (P<0.05) than Tilapia fish. Whereas, the concentrations of Copper in the different tissues of Tilapia were higher (P<0.05) than Catfish. Moreover, the concentration of all the metals determined in water, sediment and fish samples were below allowable limit of World Health Organization (WHO). This finding indicates that the water is safe for both aquatic life and man and consumption of fish from this river does not pose any risk of heavy metal contamination to consumers. However, there is need for continual assessment of the level of pollution of this river with a view to reducing the level of pollution via education and public enlightenment.
