Abstract

Abidemi Iromini, Atilola O

Head, trunk and tail of juvenile Clarias gariepinus exposed to pollutants; Detergent, Spent Oil and Detergent & Spent Oil in the volume 20 mg/L, 4 mg/L and 20 mg/L & 4 mg/L respectively, and were observed for the uptake of some selected heavy metals (Cu, Pb, Fe, Mn, and Zn). The study reveals the contamination of fish samples with heavy metals. The uptake of heavy metals in Fish samples were in the order of Fe> Zn> Cu> Mn> Pb in all pollutants, in the trend of Head>Trunk>Tail. The highest mean concentration was observed in Fe 48.33 ± 0.88(mg/kg) in the head of samples treated with detergent and Spent Oil, with uptake levels higher than the maximum permissible limits prescribed by WHO/ FAO. Whereas the concentration of heavy metals Cu, Pb, Mn and Zn were below the maximum permissible limits. The lowest mean concentration was observed in the tail.
