Background and Objective: Given the negative effects of heavy metals and their transmission to humans through the food chain, the present study was conducted to assess the concentration of heavy metals—including Fe, Zn, Cd, Pb, Ba, Ni, Cu, V, and As—in the gill, liver, and muscle tissues of the commercial fish Lutjanus ehrenbergii.
Material and Methods: Thirty fish were collected from coral habitats around Hengam Island in 2022 using nets or hooks. After identification and bioassay, the liver, gill, and muscle tissues were dissected from each specimen and analyzed for heavy metal concentrations via ICP-MS.
Results: Biometric analysis showed the average standard length, total length, and weight of the studied fish to be 23.3 ± 1.4 cm, 27.8 ± 2.7 cm, and 470.3 ± 18.9 g, respectively. Among the studied elements, Fe had the highest mean concentration in the gill (327.41 µg/g) and liver (136.10 µg/g) tissues. In muscle tissue, Zn showed the highest mean concentration (2.68 µg/g), while Ni showed the lowest accumulation. The mean Pb concentrations detected in the gill, liver, and muscle tissues were 1.38, 1.35, and 0.46 µg/g, respectively.
Conclusion: The Pb concentration in the muscle, which is the main nutritional tissue, was 0.46 µg/g. This value is higher than the limits set by international standards such as the WHO. Therefore, from a health perspective, it is not recommended to consume commercial fish contaminated with heavy metals. While continuous monitoring can provide information on contamination status, the consumption of Lutjanus ehrenbergii caught around Hengam Island should be done with caution.
