The dry digestion method was used to prepare the samples for heavy metals determination using Flame Atomic Absorption Spectrometer. Also, moisture, ash and total solids contents were determined, and Kjeldahl method was used to estimate proteins. The results showed that the average concentrations of heavy metals varied significantly with sample kind. The levels of the studied metals were as follows: 0.075 - 1.167, 31.50 - 116.00, 0.325 - 1.325, 9.425- 71.00, 0.025-3.87, 8.325- 24.825, 0.175- 1.250, 0.050- 0.750, 43.00- 98.325 mg/kg, for Co, Zn, Ni, Mn, Pb, Cu, Cr, Cd, and Fe, respectively. Also, levels of moisture contents, ash contents, total solids contents, and protein levels were: 4.0 - 8.5%, 2.0 - 11.39%, 91.5 - 96.0%, and 11.8 - 33.2%, respectively. Most of the obtained results were consistent with the previous studies and within the permissible limits.
