Marine fishes are exposed to great human-induced alterations due to the indiscriminate discharges into the sea, increasing marine pollution. For this study, 324 specimens of Sardina pilchardus from the Canary Islands were analized during a period of 2 years (June 2016 to May 2018). The concentration of 11 metals and trace elements (Al, B, Cd, Cr, Cu, Fe, Li, Ni, Pb, V and Zn) was determined in each individual using the Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) technique. Statistical analyses were carried out considering the following factors: oceanographic season, maturity of the gonads in the seasons, size of the specimens. Sardina pilchardus specimens captured in the hot season presented higher Ni, Li and Pb levels than the specimens caught in the cold season. Immature specimens had higher concentration in more metals than the mature specimens. This fact may be due to the fact that these specimens require a much higher metabolic rate due to their growth and do not detoxify like mature specimens. Significant differences were found in the concentration of metals in all the analyzes performed.

由于不分青红皂白地排入海洋，海水鱼类容易遭受人为改变，从而加剧了海洋污染。在这项研究中，在2年内（2016年6月至2018年5月）对来自加那利群岛的324个沙丁鱼进行了分析。使用电感耦合等离子体发射光谱（ICP-OES）技术确定每个个体中11种金属和微量元素（Al，B，Cd，Cr，Cu，Fe，Li，Ni，Pb，V和Zn）的浓度。进行统计分析时要考虑以下因素：海洋季节，季节中性腺的成熟度，标本的大小。沙丁鱼在高温季节捕获的标本比在寒冷季节捕获的标本具有更高的Ni，Li和Pb水平。未成熟的样品比成熟的样品具有更高的金属浓度。该事实可能是由于以下事实：这些标本因其生长而需要更高的代谢速率，并且不像成熟标本那样排毒。在所有执行的分析中，发现金属浓度存在显着差异。
