Abstract

Concentrations of seven heavy metals (Cadmium, Lead, Zinc, Nickel, Iron, Copper, and Manganese) in five canned fish samples found in the local market Basrah city, Iraq were determined after digestion according to the Association of Official Analytical Chemists methods. Concentrations of metals were measured using the Flame Atomic Absorption Spectrophotometer. The results showed that the range obtained for the elements analyzed in mg/kg (dry weight) were as follows, Cd (0.0027 - 0.0078), Pb (0.0048 - 0.0093), Zn (0.0103 - 0.0205), Ni (0.0122 - 0.0128), Fe (0.0149 - 0.0237), Cu (0.0008 - 0.0034) and Mn (0.0014 - 0.0037). The results indicated that canned fish samples in this study have concentrations well below the permissible FAO/WHO levels for these toxic metals.
