Environmental pollution due to heavy metals is having an increased impact on marine wildlife accentuated by anthropogenic changes in the planet including overfishing, agricultural runoff and marine emerging infectious diseases. Sea turtles are considered sentinels of ecological health in marine ecosystems. The objective of this study was to determine baseline concentrations of zinc, cadmium, copper, nickel, selenium, manganese, mercury and lead in blood of 22 clinically healthy, loggerhead turtles (Caretta caretta), captured for several reasons in Puerto López Mateos, Baja California Sur, Mexico. Zinc was the most prevalent metal in blood (41.89 μg g⁻¹), followed by Selenium (10.92 μg g⁻¹). The mean concentration of toxic metal Cadmium was 6.12 μg g⁻¹ and 1.01μg g⁻¹ respectively. Mean concentrations of metals followed this pattern: Zn>Se>Ni>Cu>Mn>Cd>Pb and Hg. We can conclude that blood is an excellent tissue to measure in relatively non-invasive way baseline values of heavy metals in Caretta caretta.
重金属造成的环境污染对海洋野生动物的影响日益加剧，这是由于地球受到人为变化的影响，包括过度捕捞、农业径流和海洋新发传染病。海龟被认为是海洋生态系统生态健康的哨兵。本研究的目的是确定 22 只临床健康的红海龟（Caretta caretta）血液中锌、镉、铜、镍、硒、锰、汞和铅的基线浓度，这些海龟因多种原因在墨西哥南下加利福尼亚州洛佩斯·马托斯港被捕。血液中锌（41.89μg g⁻¹）是最常见的金属，其次是硒（10.92μg g⁻¹）。有毒金属镉的平均浓度分别为 6.12μg g⁻¹和 1.01μg g⁻¹。金属的平均浓度遵循以下模式：Zn>Se>Ni>Cu>Mn>Cd>Pb 和 Hg。我们可以得出结论，血液是一种极好的组织，可以以相对非侵入性的方式测量 Caretta caretta 中重金属的基线值。
