Metal contamination is one of the crucial global problems in aquatic ecosystems that can be hazardous for public health. Due to the living of the benthic fish like large-scale tongue sole (Cynoglossus arel) on the seafloor, toxicants are more accumulated in their bodies. Therefore, the accumulation of some heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, and Zn) was determined in the edible tissues of this fish species captured from Chabahar Bay located in the northern shores of the Gulf of Oman, as well as in the sediment of their environment. For this purpose, thirty fish samples and sediment from five stations were collected during wet and dry seasons. The preparation of samples was done based on standard procedures, and the concentration of metals was measured by a flame atomic absorption spectrophotometer. Besides conventional statistical analysis, Muller's index (I_geo) for the classification of contamination and the biota–sediment accumulation factor (BSAF) were calculated. Results showed that the sediment of Chabahar Bay was classified as moderately contaminated in terms of Ni (I_geo = 1.271) and Pb (I_geo = 1.019). A significant correlation was found between the levels of Ni (18.1 µg∙g⁻¹) in sediments and bio-concentration of Cu (4.85 µg∙g⁻¹), Ni, (0.591 µg∙g⁻¹) and Pb (1.2 µg∙g⁻¹) in fish tissues (p < 0.05). In conclusion, Pb content accumulated in fish or sediment was the most important from the health view.

金属污染是水生生态系统中重要的全球性问题之一，可能危害公众健康。由于大型舌鳎（Cynoglossus arel）等底栖鱼类的生活) 在海底，有毒物质更多地积聚在它们的体内。因此，从位于阿曼湾北岸的恰巴哈尔湾捕获的这种鱼类的可食用组织中测定了一些重金属（Cd、Cr、Cu、Fe、Ni、Pb 和 Zn）的积累，如以及它们环境的沉积物。为此，在雨季和旱季收集了来自五个站点的 30 个鱼类样本和沉积物。样品的制备基于标准程序进行，金属的浓度通过火焰原子吸收分光光度计测量。除了常规的统计分析，穆勒指数（I _geo) 用于污染分类，并计算了生物群-沉积物积累因子 (BSAF)。结果表明，恰巴哈尔湾沉积物的Ni（I _geo  = 1.271）和Pb（I _geo  = 1.019）属于中度污染。发现沉积物中 Ni (18.1 µg∙g ^-1 ) 的水平与 Cu (4.85 µg∙g ^-1 )、Ni (0.591 µg∙g ^-1 ) 和 Pb (1.2 µg) 的生物浓度之间存在显着相关性∙g ^-1 ) 在鱼组织中 ( p  < 0.05)。总之，从健康的角度来看，鱼类或沉积物中积累的铅含量是最重要的。
