In the present study, sea urchin Sterechinus neumayeri tissues were used for the passive biomonitoring of toxic and trace elements at the Comandante Ferraz Station, Antarctica and compared to a pristine region (Botany). As, Ba, Br, Ca, Co, Cr, Fe, K, Na, Rb, Sc, Se and Zn concentrations were determined by instrumental neutron activation analysis (INAA), while toxic metals (Cd, Hg, Ni and Pb), and Cu were determined by atomic absorption spectrometry (GF-AAS). The findings were compared to other organisms commonly applied for biomonitoring purposes and to the sediment concentrations of each sampling region. Urchins from the Ferraz Station area presented higher Br, Co, Cr, Cs, K, Se and Zn levels than the pristine location. The results obtained herein suggest S. neumayeri can be applied to the biomonitoring of Cr and Zn. The present study also contributes to knowledge of the mineral composition of the sea urchin S. neumayeri.

在本研究中，海胆Sterechinus neumayeri组织被用于南极洲 Comandante Ferraz 站的有毒和微量元素的被动生物监测，并与原始区域（植物学）进行比较。As、Ba、Br、Ca、Co、Cr、Fe、K、Na、Rb、Sc、Se 和 Zn 浓度通过仪器中子活化分析 (INAA) 测定，而有毒金属（Cd、Hg、Ni 和 Pb）、和Cu通过原子吸收光谱法(GF-AAS)测定。将这些发现与通常用于生物监测目的的其他生物以及每个采样区域的沉积物浓度进行了比较。来自费拉兹站区域的海胆表现出比原始位置更高的 Br、Co、Cr、Cs、K、Se 和 Zn 水平。本文获得的结果表明S. neumayeri可用于Cr和Zn的生物监测。本研究还有助于了解海胆 S. neumayeri 的矿物成分。
