| dc.description.abstract | This study aimed at the assessment of safety levels of heavy metals; cadmium, lead, mercury, iron and nickel (Cd, Pb, Hg, Fe and Ni) in frozen Trachurus Trachurus fish species imported and sold in Zaria metropolis. The fish species were assessed on the bases of their import batches and variations of heavy metals localization in various tissues/organs (skin, muscles, gills, liver, intestine, kidneys, brain and bones). Accumulation levels of the metals concentration in various tissues were determined with flame AAS via microwave digestion. The trend in the metals accumulation were in this other Fe > Hg > Pb > Ni > Cd. There is significant variations (p<0.05) in the heavy metals accumulation across the batches of various tissues; majorly liver, intestine and kidneys accumulates highly than the corresponding skin, muscles, gills, brain and bones. Also, the concentrations of heavy metals obtained across the entire tissues of Trachurus Trachurus fish species was found to be higher rather than showed significance (p<0.05) as compared to the safety limits recommended by FAO/WHO. However, human health with respects to consumptions of fish livers, intestine and kidneys may face considerable risk from ingestion of toxic metals at unacceptable concentrations. | en_US |
