Introduction
Marine products play a significant role in providing food for the people of the world, but rapid population growth and industrialization have led to the introduction of pollutants such as heavy metals into aquatic animals, one of the main pollutants of these important food sources.
Materials & Methods
This study was conducted in 2017 on 30 canned tuna fish that were purchased randomly from supermarkets in Neyshabur city. The chemical digestion of the mples was measured by wet digestion and the concentration of heavy as metals using the ICP-OES device. Finally, using SPSS v.16, analytical tests ANOVA and KrusKal Wallis, the presence or absence of significant differences was detected at 95% level (P = 0.05) in tuna fish samples.
Results
The average concentration of mercury, lead, cadmium, nickel, and Tin in canned tuna samples were 0.125±0.6, 0.324±0.118, 0.07±0.11, 0.498±0.127, 1.038±0.624 respectively. There is a significant difference between the mean nickel and lead in 4 types of tuna fish, but there is no significant difference between the mean of cadmium, mercury, and tin in 4 types of tuna fish.
Conclusion
The average concentration of Tin metal, Mercury and Cadmium is lower than the limit stated by the FAO, WHO, but the Lead and Nickel concentrations in some samples were higher than the standard limit. Therefore, considering the potential hazards of these heavy metals and the impact on human health, it is necessary to monitor these metals in foods.
