The Galapagos Islands are one of the best-preserved archipelagos in the world. We sampled individuals of six demersal and three pelagic species. The metal concentration of liver and gonad tissues were analyzed by Inductively Coupled Plasma Optical Spectrometry. Findings suggest none of the pelagic species showed metallic concentrations that could pose a risk to their health or reproductive capacity.

S. violacea and P. clemensi Zn levels were higher in liver than in gonads, indicating that these species could be in their reproduction period. Zn risk toxicity for the study species is negligible. High concentrations of Cd were found in the liver of C. princeps, C. affinis and P. albomaculatus which could cause morphological and physiological alterations. We hypothesize that the high metal concentrations found in the demersal species could come from the volcanism of the islands, since no major sources of anthropogenic metal contamination can be found in the archipelago.

加拉帕戈斯群岛是世界上保存最完好的群岛之一。我们对六个底层和三个中上层物种的个体进行了采样。通过电感耦合等离子体光谱法分析肝脏和性腺组织的金属浓度。研究结果表明，没有一种远洋物种显示出可能对其健康或生殖能力构成风险的金属浓度。

S. violacea和P. clemensi Zn 水平在肝脏中高于性腺，表明这些物种可能处于繁殖期。研究物种的锌风险毒性可以忽略不计。在C.princeps、C.affinis和P.albomaculatus的肝脏中发现高浓度的 Cd，这可能导致形态和生理改变。我们假设在底层物种中发现的高金属浓度可能来自岛屿的火山活动，因为在群岛中找不到人为金属污染的主要来源。
