A total of 140 specimens of Scomber colias were collected from the Canary archipelago waters during the first semester of 2021, with 20 samples from each of the seven main islands. After analyzing the concentrations of metals (Al, Zn, Cd, Pb, Fe, and Cu) with ICP-OES, significant variations were observed among islands, with specimens from Tenerife and Gran Canaria containing higher levels of Al, Cd, and Pb, while those from Lanzarote and Fuerteventura had elevated levels of Zn, Fe, and Cu. These differences are probably related to greater anthropogenic activity around Tenerife and Gran Canaria coasts, leading to higher pollution levels, and the influence of Saharan dust and African upwelling on Lanzarote and Fuerteventura, enriching the waters with nutrients. Specific management strategies to mitigate marine pollution and continuous monitoring are crucial to safeguard marine ecosystems and to ensure food security.
2021年上半年，从加那利群岛海域共采集了140份大西洋鲭样本，七个主要岛屿各采集20份样本。通过电感耦合等离子体发射光谱仪（ICP-OES）分析金属（铝、锌、镉、铅、铁和铜）浓度后，发现各岛屿之间存在显著差异，特内里费岛和大加那利岛的样本中铝、镉和铅含量较高，而兰萨罗特岛和富埃特文图拉岛的样本中锌、铁和铜含量较高。这些差异可能与特内里费岛和大加那利岛海岸周围较强的人类活动导致较高污染水平有关，以及撒哈拉沙尘和非洲上升流对兰萨罗特岛和富埃特文图拉岛的影响，使海水富含营养物质。减轻海洋污染的具体管理策略和持续监测对于保护海洋生态系统和确保粮食安全至关重要。
