This study was performed to determine the concentrations of copper (Cu), zinc (Zn), and lead (Pb) in the gill, liver, muscle, and tail fin tissues of Euthynnus affinis, Katsuwonus pelamis, and Thunnus albacares from Oman Sea. All samples were analyzed using a flame atomic absorption spectrophotometer and the results were expressed as μg g-1 dry weight. Metal concentrations were significantly higher in the liver than other tissues in three species (with some exceptions) (p < 0.05). The concentrations of metal accumulation in tissues of tuna species followed the Zn > Cu > Pb. Correlation matrix and principal component analysis (PCA) revealed that Zn and Pb have anthropogenic sources. Estimated daily intake (EDI) in three tuna species for heavy metals were below the tolerable daily intake (TDI). Also, the mean target hazard quotient (THQ) based on studied metals in three tuna species was below 1, which suggests that consumption of these fish can be safe for human health in the Oman Sea.

通过在阿曼海食用商业海鱼（白金枪鱼，Euthynnus affinis和Katsuwonus pelamis）对重金属的人类健康风险评估。

这项研究的目的是确定阿曼海产的Euthynnus affinis，Katsuwonus pelamis和Thunnus albacares的腮，肝，肌肉和尾鳍组织中铜（Cu），锌（Zn）和铅（Pb）的浓度。使用火焰原子吸收分光光度计分析所有样品，并将结果表示为μgg-1干重。在三个物种中，肝脏中的金属浓度显着高于其他组织（p <0.05）。金枪鱼物种组织中金属积累的浓度遵循Zn> Cu> Pb。相关矩阵和主成分分析（PCA）表明，Zn和Pb具有人为来源。三种金枪鱼物种的重金属估计每日摄入量（EDI）低于可耐受的每日摄入量（TDI）。也，根据对三种金枪鱼物种的研究金属得出的平均目标危害商（THQ）低于1，这表明食用这些鱼对阿曼海的人类健康是安全的。图形概要 。
