This study determined the concentrations of heavy metals in blood collected from Pacific Ridley sea turtles (Lepidochelys olivacea) inhabiting the coast of Guasave, Mexico, in the Gulf of California. The highest reported metal concentration in blood was Zn, followed by Se. Of nonessential toxic metals, As was reported in higher percentage compared to Cd. The concentrations of metals detected were present as follows: Zn > Se > Mn > As > Ni > Cd > Cu. Cd concentration in blood is higher in our population in comparison with other populations of L. olivacea, and even higher in other species of sea turtles. Our study reinforces the usefulness of blood for the monitoring of the levels of contaminating elements, and is easily accessible and nonlethal for sea turtles.
本研究测定了栖息在墨西哥加利福尼亚湾瓜萨维海岸的太平洋丽龟（Lepidochelys olivacea）血液中的重金属浓度。血液中报告的最高金属浓度是锌，其次是硒。在非必需的有毒金属中，砷的含量比镉高。检测到的金属浓度如下：锌>硒>锰>砷>镍>镉>铜。与其他太平洋丽龟种群相比，我们种群血液中的镉浓度更高，甚至比其他海龟物种的镉浓度更高。我们的研究证实了血液监测污染元素水平的有用性，而且对海龟来说，这种方法容易获得且无致命性。
