Abstract

Sea urchin species are ecologically important in the Gulf of California and are becoming popular as a local fishery due to their commercial value. The most abundant species are Echinometra vanbrunti, Eucidaris thouarsii, and Tripneustes depressus. The objective of this study was to evaluate cadmium, lead, copper, zinc, and iron concentrations, as well as stable isotope values in these sea urchin species in the Santa Rosalia mining area (STR), in three sites: Punta Gorda, Punta el Aterrizaje, and Punta Salina. The highest Fe concentration (100.2 mg kg^-1) was found in E. vanbrunti, while the highest concentrations of Pb (15.1 mg kg^-1), Cu (14.5 mg kg^-1), and Zn (347.7 mg kg^-1) were recorded in E. thouarsii, and the highest Cd concentration (10.8 mg kg^-1) was found in T. depressus. The main health risk of trace metal pollution in STR may be caused by Cd and Pb. δ¹⁵N and δ¹³C values were higher in E. thouarsii and T. depressus, respectively; E. thouarsii has the highest trophic position. Specimen size was not related to metal concentrations, but a positive relationship was observed between specimen size and isotopic values in T. depressus. The three species showed different bioaccumulation patterns for the metals analyzed. Additionally, collection sites and seasons play an important role in the variability of metal concentration.

加利福尼亚湾三种海胆的痕量金属污染和营养位置。

海胆物种在加利福尼亚湾具有重要的生态意义，因其商业价值而成为当地的热门渔产。最丰富的物种是 Echinometra vanbrunti、Eucidaris thouarsii 和 Tripneustes depressus。这项研究的目的是评估圣罗萨里亚矿区（STR）三个地点的这些海胆物种中的镉、铅、铜、锌和铁浓度以及稳定同位素值：Punta Gorda、Punta el Aterrizaje 和 Punta Salina。E. vanbrunti 的铁含量最高（100.2 毫克/千克-1），E. thouarsii 的铅（15.1 毫克/千克-1）、铜（14.5 毫克/千克-1）和锌（347.7 毫克/千克-1）含量最高，T. depressus 的镉含量最高（10.8 毫克/千克-1）。痕量金属污染对健康的主要危害可能是镉和铅。E. thouarsii 和 T. depressus 的 δ15N 和 δ13C 值分别较高；E. thouarsii 的营养级最高。标本大小与金属浓度无关，但在 T. depressus 中观察到标本大小与同位素值之间存在正相关。这三个物种对所分析的金属表现出不同的生物累积模式。此外，采集地点和季节对金属浓度的变化也有重要影响。

期刊介绍： Ecotoxicology is an international journal devoted to the publication of fundamental research on the effects of toxic chemicals on populations, communities and terrestrial, freshwater and marine ecosystems. It aims to elucidate mechanisms and processes whereby chemicals exert their effects on ecosystems and the impact caused at the population or community level. The journal is not biased with respect to taxon or biome, and papers that indicate possible new approaches to regulation and control of toxic chemicals and those aiding in formulating ways of conserving threatened species are particularly welcome. Studies on individuals should demonstrate linkage to population effects in clear and quantitative ways. Laboratory studies must show a clear linkage to specific field situations. The journal includes not only original research papers but technical notes and review articles, both invited and submitted. A strong, broadly based editorial board ensures as wide an international coverage as possible.
