Background and Aim: Mercury is the most dangerous metal in the environment which accumulates in fish tissues as it enters aquatic ecosystems and eventually enters the human food chain. According to the carcinogenicity of mercury in humans, this review study aimed to assess the health risk of mercury in the edible tissue of some fish in southwest of Iran.
Material and Method: In this study, the information from the studies conducted by the authors of this paper, which have been done on the bioaccumulation of mercury in fish in recent years, were provided. The selection criteria for this study were the southwestern region of Iran, the articles’ year of publication, the type of aquatic (fish), and the method of mercury measurement. The US Environmental Protection Agency's risk assessment guidelines were used to assess the daily intake and risk of metals for the health of the individuals consuming fish.
Results: According to the per capita consumption of fish in Iran, the amount of mercury that is absorbed through the consumption of the studied fish is about the body of adults (an adult weighing 70 kg) and children (a child weighing 14.5 kg), about 0.005-0.460 and 0.027-2.222 mg/Kg. Also, the probability of risk in adults was 0.05-4.60. In children, the risk of fish consumption was 0.27-22.22. The permissible amount of fish to be studied with an average concentration of 0.05-1.289 mg/Kg of mercury is 0.543-43.75 g/day. Also, the maximum daily consumption of fish for children was obtained with an average concentration of 0.05-1.289 mg/Kg of mercury, 0.112-9.062 g/day.
Conclusion: In this study, the health risk of mercury in the consumption of Barbus grypus, Barbus xanthopterus, and Periophthalmus waltoni was over 1 for both adult and child individuals. It is advisable to pay more attention to the consumption of these fish
