Heavy metal profile in a smoked Cynoglossus Fish species from selected markets in Owo Town, South Western, Nigeria


Author(s): Wangboje OM and Miller AM

Abstract: The dearth of information on the levels of heavy metals in smoked fishes sold in various markets in Owo town, Ondo state, Nigeria, warranted this research against the backdrop of the popularity of smoked fish products amongst the populace. Specifically, the levels of Pb, Cd, Cu and Zn in smoked Cynoglossus senegalensis (Mean total length= 31.35 cm; Mean weight= 37.72 g) were quantified by Atomic Adsorption Spectrometric technique in order to ascertain their suitability for human consumption. The mean heavy metal concentrations in smoked C. senegalensis, ranged from 0.10 mg/kg (Cu) to 61.11 mg/kg (Zn) while the mean concentrations of metals in fish by market ranged from below detection limit for Cd at Iyere market to 66.77 mg/kg (Zn) at Oba market. The toxic/hazard quotient (TQ) values for Pb, Cd and Zn indicated a risk to the potential fish consuming public. Smoked C. senegalensis must thus be consumed with caution because of the risk associated with heavy metal poisoning especially from Pb, Cd and Zn over time.
