Heavy metals are continuously released into the oceans from both natural and anthropogenic sources. They are serious threats to both ecosystem and human health because of their toxicity, persistence, bioaccumulation, and biomagnification. We present metal concentrations in the economically important bluefish from Iskenderun Bay, providing valuable information on Northeastern Mediterranean aquatic ecosystem health, as well as the human health risk. The concentrations of manganese, iron, copper, zinc, selenium, cadmium, lead, and mercury were determined in the gill, liver, and muscle tissues of bluefish (Pomatomus saltatrix) caught in Iskenderun Bay (Turkey) during four seasons. Samples were analysed via inductively coupled plasma mass spectrometer. Fe and Zn were detected in the highest concentrations during all four seasons. The ranges of Fe concentrations were 61.15–108.76, 229.78–377.02, and 6.35–8.63 and those of Zn were 25.21–44.25, 42.25–76.08, and 6.27–13.59 in the gills, livers, and muscles, respectively. In contrast, Hg and Cd were not found in the bluefish tissues in any season with the exception of Cd in the gills during the spring (0.757 mg/kg, above the legal limit of 0.5 mg/kg). On a seasonal basis, no meaningful accumulation trend was observed for the muscles or gills, while the highest concentrations of Mn, Fe, Cu, Zn, and Se in the liver were found in the spring. Liver tissues possessed higher metal concentrations than gill and muscle tissues. Estimated daily and weekly intakes of the metals due to human consumption of the bluefish were considerably lower than the provisional tolerable intake. In this study, there was an inflow of metals into Iskenderun Bay; however, no significant metal accumulation was found in bluefish tissues at a rate that would harm human health.

重金属不断从自然和人为来源释放到海洋中。由于它们的毒性、持久性、生物累积性和生物放大性，它们对生态系统和人类健康构成严重威胁。我们展示了来自伊斯肯德伦湾的具有重要经济意义的蓝鱼的金属浓度，提供了关于东北地中海水生生态系统健康以及人类健康风险的宝贵信息。测定了蓝鱼（Pomatomus saltatrix）的鳃、肝脏和肌肉组织中锰、铁、铜、锌、硒、镉、铅和汞的浓度。）在四个季节期间在伊斯肯德伦湾（土耳其）捕获。通过电感耦合等离子体质谱仪分析样品。在所有四个季节中，铁和锌的含量最高。Fe浓度范围分别为61.15-108.76、229.78-377.02和6.35-8.63，Zn在鳃、肌肉和肌肉中分别为25.21-44.25、42.25-76.08和6.27-13.59。相比之下，除了春季鳃中的镉（0.757毫克/千克，高于0.5毫克/千克的法定限值）外，其他任何季节的蓝鱼组织中均未发现汞和镉。在季节性基础上，没有观察到肌肉或g的有意义的蓄积趋势，而春季发现肝脏中锰，铁，铜，锌和硒的最高浓度。肝组织比鳃和肌肉组织具有更高的金属浓度。由于人类食用蓝鱼，估计每日和每周金属摄入量大大低于临时耐受摄入量。在这项研究中，有金属流入伊斯肯德伦湾；然而，在蓝鱼组织中没有发现显着的金属以危害人类健康的速度积累。
