The concentration of 19 metal and non-metal elements in two fishes (Liza subviridis and Sphyraena jello) and associated sediment-seawater from the northern part of the Persian Gulf was measured. The samples were gathered from two industrial ports, one commercial port, and one residential port. The metal accumulation in the muscle and liver of fishes was evaluated. Nickel (mean 362.07-712.83 μg/g) and chromium (mean 470.00-691.47 μg/g) in sediment and zinc (mean 9.01-31.15 μg/L) and arsenic (mean 18.22-22.14 μg/L) in seawater had the most abundancy among studied elements. The accumulation of elements in S. jello (a pelagic species) was higher than L. subviridis (a demersal species). For both species, major elements of S and Mg and trace elements of Fe, Al, Si, Zn, and Cu showed highest accumulation. Also, fish samples from Emam Hassan Port were more contaminated than other stations. Ecological indexes values have revealed a low to moderate elemental pollution of sediment and fish samples in the north part of the Persian Gulf.

波斯湾北岸鱼类和相关沉积物-海水中的微量元素和主要元素浓度。

测量了来自波斯湾北部的两种鱼类（Liza subviridis 和 Sphyraena jello）和相关沉积物海水中 19 种金属和非金属元素的浓度。样本来自两个工业港口、一个商业港口和一个住宅港口。评估了鱼类肌肉和肝脏中的金属积累。沉积物中镍（平均 362.07-712.83 μg/g）和铬（平均 470.00-691.47 μg/g）和海水中锌（平均 9.01-31.15 μg/L）和砷（平均 18.22-22.14 μg/L）含量最高研究元素之间的丰富性。S. jello（一种远洋物种）中元素的积累高于 L. subviridis（一种底层物种）。对于这两个物种，S 和 Mg 的主要元素以及 Fe、Al、Si、Zn 和 Cu 的微量元素显示出最高的积累。还，来自 Emam Hassan 港的鱼类样本比其他站点受到的污染更严重。生态指标值显示波斯湾北部的沉积物和鱼类样本存在低至中度元素污染。
