Dangers of Bioaccumulation of some heavy metals consumed in Sardine and Mackerel (ice fish) in Benue State Nigeria
Abstract
Buck Scientific Atomic Absorption Spectrophotometer (AAS) VGP 2110 was used to investigate the presence of Lead(Pb), cadmium (Cd) and Iron (Fe) in Mackerel and Sardine fish species popularly referred to as ice fish consumed in Benue State and Nigeria . In Sardine the total concentration was 0.0105, 0.016, 15.1 mg/L for Lead(Pb), Cadmium (Cd), and Iron (Fe) ) respectively . Mackerel had the concentration of 0.013 , 0.063 , 16.06 mg/L of Lead(Pb), cadmium (Cd), and Iron (Fe) respectively. The result seem within the international standards safe for consumption of these fish . Continuous consumption can also lead to bioaccumulation and biomagnifications of these metals in the human body exposing it to danger .
