Abstract :
Introduction: Fish meat may be contaminated to toxic metals during commercial transport and processing depending on the raw material before processing occurs. Therefore, monitoring of these products is important with respect to toxic elements affecting human health. Objective: The aim of this study is to assess toxic metals in canned fish marketed in Tehran,Iran. Methods: This study based-cross-sectional was carried out in five different Iranian brands. Forty six canned fishes from this brands elected and toxic metal were determined using the flame and graphite furnace atomic absorption spectrometry after microwave digestion. The accuracy of the method was ascertained by standard reference material (NRCC-DORM-2 Dogfish Muscle). Result: In this study was observed that some cases may be containing iron, lead and mercury above the legal limit set by the health authorities. The concentration of the toxic metals in the canned fish samples were found to be in the ranges of 1.29 - 2.45 g/g, , 8.34 - 36.4 g/g, 1.20 - 2.70 g/g, 11.2 - 28.3 g/g, 1.30 - 3.65 g/g, 0.49 - 2.15 g/g, 0.90 - 1.87 g/g, 0.58 - 1.04 g/g, 0.18 - 0.38 g/g, and 0.03 - 0.12 g/g for copper, zinc, manganese, iron, selenium, aluminum, chromium, nickel, lead and cadmium, respectively. Conclusion: Comparison of the results obtained in this study with the values reported in literature showed that the consumption of the five (5) brands of the canned tuna does not pose any risk to the health of consumers particularly with respect to zinc, copper, cadmium and tin concentrations; though some of the brands contained iron, lead and mercury above the legal limits set up by some health authorities. It was, however, recommended that comprehensive and periodic monitoring of the trace metals in the canned tuna must continue to ensure the protection of the health of the consumers.
