| Heavy metals with their property of stability and indestructibility, accumulate over time in various tissues of aquatic organisms, including skin, bone, muscle, etc., and from this path enter the food chain and reach higher levels and consumption by other species are transferred. The present study was conducted to measure the amounts of heavy metals lead, nickel, zinc, iron and copper in the edible tissue of fish table islands (Qeshm, Hengam and Hormoz) in Hormozgan province. In the three mentioned regions, during the two seasons of summer and winter, a total of 180 samples were collected in 1398 (30 samples in each station and in each season separately). After bioassay, the concentration of heavy elements in the studied organ was measured using a flame atomic absorption device (Model 700Contr AA). The results showed that the highest mean concentrations of lead, nickel, zinc and copper were observed in Qeshm Island and iron metal in Hormoz Island and the lowest mean concentrations of metals were observed in Hengam Island. Metal concentrations in the analyzed samples were lower than international standards FAO, WHO, FDA, NHMRC and UKMAFF. Also, the level of potential risk and risk index for non-cancerous diseases in adults and children in the aquifer muscle tissue was less than 1. Therefore, it can be concluded that there are currently no problems for human health in terms of consumption of this fish. |
