Comparative Assessment and Source Identification of Heavy Metals in Selected Fishpond Water, Sediment and Fish Tissues/Organs in Osun State, Nigeria
Background. The potential toxicity of metals in water may have detrimental effects on the biochemical processes of aquatic organisms, especially fish, which serve as a source of protein in the protein-deficient Nigerian diet. Objective. The present study aimed to determine the concentration of heavy...

The potential toxicity of metals in water may have detrimental effects on the biochemical processes of aquatic organisms, especially fish, which serve as a source of protein in the protein-deficient Nigerian diet. Objective. The present study aimed to determine the concentration of heavy metals in African catfish (C. gariepinus) and investigate the health risk associated with heavy metals in fish. Methods. Heavy metal concentrations in the water samples were determined using atomic absorption spectrophotometry (AAS) and particle induced x-ray emission spectroscopy (PIXE) for sediment and fish tissues/organ samples. Results. Mean nickel (Ni) concentrations differed significantly (p<0.05) by sample type in both the dry and rainy seasons. Similarly, during the rainy season, mean lead (Pb) concentrations in all of the samples from Osogbo differed significantly (p<0.05) by type, with the highest concentration in fish muscle (10.11±1.21 μg/kg) and the lowest Pb concentration in pond water (1.72±0.05 μg/L). Mean chromium (Cr) concentrations of samples from the Ewuru/Rara stream in Yakoyo also differed significantly (p<0.05) by type, with the highest concentration in fish muscle (113.10.±10.07 μg/kg) and the lowest concentration in pond water (3.31±0.22 μg/L).
