Studies of the content of heavy metals and trace elements in fish and other marine organisms are of great importance to know the state of the marine ecosystem. This study has been carried out in northwestern African waters, Scomber colias being the target species, sampling a total of 345 specimens over 2 years. For the determination of metals and trace elements (Al, B, Cd, Cr, Cu, Fe, Li, Ni, Pb, V, and Zn) in the muscle, the ICP-OES (inductively coupled plasma optical emission spectrometry) was used. In the statistical study, the factors (oceanographic and maturity in the seasons, size of the specimens) were used. The samples sampled in the cold season that had high concentrations of metals may be due to the influence that African upwelling has on the Canary Islands. The metallic contents of our samples are lower than those found in the studies in Mauritania and Morocco due to the greater influence that upwelling has in these areas.
研究鱼类和其他海洋生物体内的重金属和微量元素含量对于了解海洋生态系统的状况非常重要。本研究在西北非海域进行，以竹荚鱼为目标物种，在 2 年内共采集了 345 个样本。为了测定肌肉中的金属和微量元素（Al、B、Cd、Cr、Cu、Fe、Li、Ni、Pb、V 和 Zn），使用了电感耦合等离子体光学发射光谱法（ICP-OES）。在统计研究中，使用了季节中海域和成熟度以及样本大小等因素。在寒冷季节采集的样本中金属浓度较高，可能是因为非洲上升流对加那利群岛的影响。由于上升流在这些地区的影响更大，我们样本中的金属含量低于在毛里塔尼亚和摩洛哥进行的研究中发现的含量。
