Offshore volcanic activity occurs when an underwater volcano erupts. These volcanoes can be located underwater or on land and can be very dangerous to marine life. The aim of this study is to examine whether the influence of two volcanoes has an effect on the concentrations of metals and trace elements in the Atlantic mackerel Scomber colias in the Canary Islands. For the study, ten specimens of S. colias were obtained from each sampling area in March 2022. Metal concentrations were determined by inductively coupled plasma optical emission spectrophotometry (ICP-OES). The specimens of Scomber colias from the area affected by the Tajogaite volcano (La Palma) showed higher concentrations of all metals and trace elements analyzed than those from the other study areas. The specimens from the area of influence of the Tagoro Volcano (El Hierro) showed the second highest concentration of the elements studied, although this volcanic process is in a state of degassing.
当水下火山喷发时，就会发生近海火山活动。这些火山可以位于水下或陆地上，对海洋生物非常危险。本研究的目的是检验两座火山的影响是否会对加那利群岛大西洋鲭鱼 Scomber colias 中金属和微量元素的浓度产生影响。为此，于 2022 年 3 月在每个采样区采集了 10 条 S. colias 样本。采用电感耦合等离子体光学发射光谱法（ICP-OES）测定金属浓度。受 Tajogaite 火山（拉帕尔马岛）影响地区的 Scomber colias 样本中所有分析金属和微量元素的浓度均高于其他研究区。受 Tagoro 火山（耶罗岛）影响地区的样本中研究元素的浓度位居第二，尽管这一火山活动处于放气状态。
