Concentrations of copper (Cu), iron (Fe), manganese (Mn), nickel (Ni) and zinc (Zn) in muscle and gills of four Benthic fish species (Brachirus orientalis, Argyrops spinifer, Platycephalus indicus and Sillago sihama) from Shif Island of Iran were analyzed using flame atomic absorption spectrometry. The heavy metal levels observed in tissues varied for Cu: 2.15-820.98, Fe: 24.46-533.26, Mn: 1.80-53.17, Ni: 1.86-65.54 and Zn: 28.77-375.79 mg/kg. Significant differences were found among muscle and gill of the four fish species. Heavy metals concentration were significantly (p < 0.05) higher in the gill than in the muscles of all fish species studied. The metal levels in benthic fish species should be continuously monitored in polluted areas since benthic fish indicated a tendency to bioaccumulate pollutants in their tissues from polluted water. The indices of Estimated Daily Intake, Target Hazard Quotient and Hazard Index suggests no risk while carcinogenic risk for Ni showed unacceptable carcinogenic risk.
采用火焰原子吸收光谱法分析了伊朗希法岛的 4 种底栖鱼类（Brachirus orientalis、Argyrops spinifer、Platycephalus indicus 和 Sillago sihama）肌肉和鳃中的铜（Cu）、铁（Fe）、锰（Mn）、镍（Ni）和锌（Zn）浓度。组织中观察到的重金属水平为 Cu：2.15-820.98、Fe：24.46-533.26、Mn：1.80-53.17、Ni：1.86-65.54 和 Zn：28.77-375.79 mg/kg。四种鱼类的肌肉和鳃之间存在显著差异。所有研究鱼类的鳃中重金属浓度均明显高于肌肉（p<0.05）。由于底栖鱼类从受污染的水中倾向于在其组织中生物积累污染物，因此应在污染地区持续监测底栖鱼类的金属水平。估计每日摄入量、目标危害系数和危害指数指数表明无风险，而 Ni 的致癌风险则显示出不可接受的致癌风险。
