The concentrations of trace elements including As, Zn, Cu, Se, Pb, Hg and Cd, were determined in the blood of nesting Kemp's ridley turtles (Lepidochelys kempii) at Rancho Nuevo sanctuary, Tamaulipas, Mexico during 2018-2020. The sequential concentrations analyzed were Zn> Se> Cu> As> Pb; while Cd and Hg concentrations were below the limits of detection (0.01 μg g-1). No significant differences were observed between the concentrations of trace elements (p> 0.05) by year, except Se levels, possibly resulting from recorded seasonal differences in turtle size. No relationships among turtle size vs elements concentration were observed. In conclusion, essential and toxic trace elements concentrations in the blood of nesting Kemp's ridley turtles may be a reflex of the ecosystem in which the turtles develop, that is, with low bioavailability of elements observed in the trophic webs in the Gulf of Mexico.
在 2018 年至 2020 年期间，在墨西哥塔毛利帕斯州拉兰乔努埃沃保护区，对筑巢坎皮海龟（Lepidochelys kempii）血液中的痕量元素（包括砷、锌、铜、硒、铅、汞和镉）浓度进行了测定。分析的顺序浓度为 Zn>Se>Cu>As>Pb；而 Cd 和 Hg 浓度低于检测限（0.01μg g-1）。除了硒水平外，各年份痕量元素浓度（p>0.05）均无显著差异，这可能是由于海龟大小的季节性差异所致。未观察到海龟大小与元素浓度之间的关系。总之，筑巢坎皮海龟血液中的必需和有毒痕量元素浓度可能反映了海龟发育的生态系统，即墨西哥湾营养级联中观察到的元素生物利用度较低。
