Abstract :
The residual concentration levels of copper (Cu), iron (Fe), lead (Pb), cadmium (Cd), and arsenic (As) in commercially and home-produced eggs of hen and duck rolled in Mansoura city marketes, Egypt were determined. Therefore, 80 egg samples were randomly collected from different grocery stores to be analyzed using Flame Atomic Absorption Spectrometry. The examined eggs samples comply the permissible limits for trace elements in table eggs except Lead which only 95% brown shell hen egg, 65% Baladi hen egg, and 85% duck egg were comply the their permissible limits. Cd and As could not be detected in all examined egg samples. Acceptable Estimated Daily Intake “AEDI” was calculated as 0.325 mg for Cu, 2.652 mg for Fe, and 0.020 mg for Pb which represented 0.93%, 4.74%, and 4.08% of Accepted daily Intake “ADI” (70 kg person). The findings indicate that the concentrations level of Cu, Fe, and Pb in Eggs in Mansoura city marketes are set within the Standard limits and considered as safe for human consumption. Two large eggs (100 g) consumption/ day cover the Recommended Daily Allowance “RDA” needed for the adult person/ day from Cu but in case of Fe, other source of iron should be added to his daily diet.
