Abstract
Introduction
The concentration of heavy metals (Pb, Cr, Cd) and trace elements (Zn, Cu, Mg) were evaluated in a variety of
cow meat, goat meat and their organs.
Methods
The analysis was done using Atomic Absorption Spectrophotometry (AAS).
Results
The concentration of the heavy metals were in these range: Pb (0.06-1.44 μg/g), Cr (0.04-0.22μg/g), Cd (0.002-
0.08μg/g), As (0.02 – 0.03μg/g). The concentration of the trace elements were in these range: Zn (0.15-3.16
μg/g), Co (0.21-0.38 μg/g), Cu (0.011-0.073μg/g), Mg (0.2–2.72 μg/g).
Discussion
The concentration of arsenic in all samples examined was negligible indicating that the samples were free from
arsenic toxicity. The concentration of the other heavy metals examined were below the permissible limit of the
WHO. This shows that most of our meat products together with their organs were free from heavy metal toxicity.
However, cow liver shows a high concentration of lead but still below the tolerance limit.
Conclusion
The government shuld pay more attention to regular screening of meat for the safety of the populace.
