Marine organisms are exposed to great changes induced by human beings due, among others, to discharges into the oceans, increasing marine pollution. For this study, 294 specimens of Trachurus picturatus from the Canary Islands were analyzed during a period of 2 years. The concentration of 11 anthropic metals and trace elements 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, size of the specimens, 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.

海洋生物暴露于人类引起的巨大变化，其中包括排放到海洋中，从而加剧了海洋污染。对于本研究，有294个Trachurus picturatus标本在两年的时间内对来自加那利群岛的数据进行了分析。使用电感耦合等离子体发射光谱（ICP-OES）技术确定每个人中11种人类金属和微量元素的浓度。考虑以下因素进行了统计分析：海洋学季节，性腺成熟度，标本大小，季节。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。
