الملخص EN

Heavy metal (Pb, Cd, Mn, Ni, and Fe) concentrations in the local (Tilapia Nilotic a and Nile perch) and imported (Saba) filleted fish were investigated in Assiut city using Atomic Absorption Spectrophotometer (AAS).

The mean values of Pb, Cd, Mn, Ni and Fe were 5.17 ± 4.91, 2.15 ± 1.95, 3.6H4.35, 3.74 ± 3.52 and 30±12.56 mg / kg dry weight in local filleted fish, while in imported fish they were 6.90 ± 4.035, 2.44 ± 1.52, 4.74 ± 2.89, 1.88 ± 2.57 and 24 ± 14.15 mg / kg dry weight, respectively.

There was no significant difference in heavy metals concentrations between local filleted and imported filleted fish and also between filleted Tilapia Nilotic a and Nile perch in case of Ni and Fe, but Tilapia Nilotic a higher than Nile perch in case of Pb, Cd and Mn after statistical analysis.
