Determination of trace metals in canned fish marketed in Turkey

The levels of trace metals of canned fish samples collected from markets in Turkey were determined by flame and graphite furnace atomic absorption spectrometry after microwave digestion. The accuracy of the method was corrected by standard reference material (NRCC-DORM-2 Dogfish Muscle). The contents of investigated trace metals in canned fish samples were found to be in the range 1.10–2.50 μg/g for copper, 7.57–34.4 μg/g for zinc, 0.90–2.50 μg/g for manganese, 10.2–30.3 μg/g for iron, 0.96–3.64 μg/g for selenium, 0.45–1.50 μg/g for aluminium, 0.97–1.70 μg/g for chromium, 0.42–0.85 μg/g for nickel, 0.09–0.40 μg/g for lead and 0.06–0.25 μg/g for cadmium. The results were compared with the literature values.
