This manuscript presents preliminary information on the concentrations of heavy metals: cadmium, lead, nickel, vanadium and arsenic in 66 fish samples of four different species collected from three different sites on the Gulf coast of Saudi Arabia where there are agricultural, municipality and petroleum industrial activities. Fish species; highly consumed by the local population were selected: Emperors, Rabbitfish, Doublebar-bream and Greasy-grouper to ascertain the fish quality for human consumption. The concentration of metals was determined by atomic absorption spectrophotometry (AA). The average mean concentrations (ng/g wet wt.) of cadmium, lead, nickel, vanadium and arsenic in fish tissues were as follows: 4.6 +/- 7.2, 20.0 +/- 20.8, 60.6 +/- 63.2, 73.6 +/- 27.1 and 42.7 +/- 17.4 ng/g wet wt. respectively. The concentration of metals was significantly affected by the sampling site and fish species. In Maniefa site, the concentrations of all tested metals were higher than in Al-Dammam and Dareen sites with the exception of nickel where no significant differences were found. Levels of cadmium, lead, nickel, vanadium and arsenic varied depending on the fish species. The concentration of metals was below the maximum allowed limit by the Saudi and international legislations for fish human consumption permissible limit.
本手稿介绍了从沙特阿拉伯海湾沿岸三个不同地点采集的四种不同鱼类的66个样本中重金属镉、铅、镍、钒和砷的浓度的初步信息，这些地点存在农业、市政和石油工业活动。选择了当地居民大量食用的鱼类品种：皇帝鱼、兔鱼、双带鲷和油斑石斑鱼，以确定供人类食用的鱼类质量。通过原子吸收分光光度法（AA）测定金属浓度。鱼组织中镉、铅、镍、钒和砷的平均浓度（纳克/克湿重）如下：分别为4.6±7.2、20.0±20.8、60.6±63.2、73.6±27.1和42.7±17.4纳克/克湿重。金属浓度受采样地点和鱼类品种的显著影响。在马尼法地点，除镍外，所有测试金属的浓度均高于达曼和达林地点，镍的浓度未发现显著差异。镉、铅、镍、钒和砷的含量因鱼类品种而异。金属浓度低于沙特和国际法规规定的鱼类供人类食用的最大允许限量。
