Seafood has long been considered a unique source of nutrition. However, increasing trends in consumption of marine products must be considered, especially in potentially polluted environments such as the Persian Gulf. This study was undertaken to analyse the level of heavy metal contamination of nickel (Ni), zinc (Zn), and lead (Pb) in shrimp (Penaeus merguiensis) captured from the northern Persian Gulf. The concentration of heavy metals in the muscle of shrimp followed the order Zn > Ni > Pb. The content of Zn and Ni was higher than recommended standard limits by the FAO/WHO. The combined impact of all metals was lower than the acceptable limit of 1 in shrimp. The carcinogenic risk for Ni was higher than the unacceptable value. In total, our finding indicated no potential health risk from the daily consumption of this species. However, long-term consumption of shrimp can pose a risk of carcinogenic effects of nickel. Continuous monitoring of these trace metals in seafood is necessary to ensure the quality of seafood and food safety.
海鲜一直被认为是一种独特的营养来源。然而，必须考虑到海产品消费的增长趋势，特别是在像波斯湾这样的潜在污染环境中。本研究旨在分析从波斯湾北部捕获的对虾（Penaeus merguiensis）中重金属镍（Ni）、锌（Zn）和铅（Pb）的污染水平。对虾肌肉中重金属的浓度顺序为 Zn>Ni>Pb。Zn 和 Ni 的含量高于粮农组织/世卫组织推荐的标准限值。所有金属的综合影响低于虾中的可接受限值 1。Ni 的致癌风险高于不可接受值。总的来说，我们的研究结果表明，这种物种的日常消费没有潜在的健康风险。然而，长期食用虾可能会有镍的致癌作用的风险。对海产品中这些痕量金属进行持续监测对于确保海产品和食品安全是必要的。
