In this study, the bio-concentration of trace metals (Cd, Cr, Cu, Fe, Ni, Pb, and Zn) was determined in eight edible fish species, which were caught from the northern shores of the Gulf of Oman. For this purpose, a total of 160 fish samples in eight species, originating from different ecological status and trophic levels, were obtained twice, once during the warm season and once in winter. Sample preparation and quantification of the metals were accomplished via the wet digestion method and atomic absorption spectroscopy (AAS). The results showed that the average Cd, Cr, Cu, Fe, Ni, Pb, and Zn concentrations in the edible tissues of the fish, regardless of the species, were 0.14 ± 0.003, 0.75 ± 0.067, 2.18 ± 0.21, 55.55 ± 2.11, 0.35 ± 0.033, 0.49 ± 0.054, 6.78±0.53μgg1 DW, respectively. The data on metals presence were significantly different between the sampling stations, including for Cu and Pb in the meat of Cynoglossus arel. Therefore, based on the target hazard quotient (THQ), any serious threat to public health would not be due to the consumption of the Gulf of Oman’s captured seafood, and consumers would be able to use seafood safely.

从伊朗阿曼湾北岸捕获的海洋鱼类中金属的生物富集

在这项研究中,测定了从阿曼湾北岸捕获的八种食用鱼类中的痕量金属(镉,铬,铜,铁,镍,铅和锌)的生物浓度。为此目的,两次获取了八个物种的160种鱼类样本,这些样本来自不同的生态状况和营养水平,一次是在温暖的季节,一次是在冬季。金属样品的制备和定量通过湿消解法和原子吸收光谱法(AAS)完成。结果表明,鱼的可食组织中的Cd,Cr,Cu,Fe,Ni,Pb和Zn的平均浓度(不论种类如何)分别为0.14±0.003、0.75±0.067、2.18±0.21、55.55±2.11 ,0.35±0.033、0.49±0.054,678±053μGG-1个DW,分别。采样站之间有关金属存在的数据存在显着差异,包括食蟹猴肉中铜和铅的含量。因此,基于目标危险商(THQ),对公共健康的任何严重威胁都不会由于消耗阿曼湾捕获的海产品而引起,消费者将能够安全地使用海产品。
