Dangers of Bioaccumulation of some heavy metals consumed in Sardine and Mackerel (ice fish) in Benue State Nigeria

Beetseh C I, Abrahams J O


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 .

Key words: Accumulation ,  Consumption ,Equilibrium ,Metabolism ,  Supply.
