Some trace elements are essential for the health of vertebrates, but little is known about their function, the amounts required, and the factors influencing their metabolism in tortoises. The aim of this study was therefore to measure trace elements (chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn)) in heparinized blood plasma of Hermann's tortoises () ( = 520) from March to September 2022 using inductively coupled plasma mass spectrometry (ICP-MS) and to establish specific reference intervals. Additionally, the influence of sex, season, and region of sample collection on the measured values were evaluated. Significant ( ≤ 0.05) sex-specific differences were found for Cu, Mg, and Mn; seasonal differences were found for Cr, Cu, Mn, Mo, and Se; and the region in which the tortoises were kept significantly impacted Cr, Cu, Fe, Mg, Mo, and Se levels. The results show that all of these factors should be consider when establishing and interpreting blood trace element levels in tortoises.
一些微量元素对脊椎动物的健康至关重要,但对于它们在陆龟中的功能、所需量以及影响其新陈代谢的因素却知之甚少。因此,本研究的目的是使用电感耦合等离子体质谱法(ICP-MS)测量2022年3月至9月期间赫尔曼陆龟( = 520)肝素化血浆中的微量元素(铬(Cr)、钴(Co)、铜(Cu)、铁(Fe)、镁(Mg)、锰(Mn)、钼(Mo)、硒(Se)、锌(Zn)),并建立特定的参考区间。此外,还评估了性别、季节和样本采集区域对测量值的影响。发现Cu、Mg和Mn存在显著的( ≤ 0.05)性别特异性差异;Cr、Cu、Mn、Mo和Se存在季节差异;陆龟饲养的区域对Cr、Cu、Fe、Mg、Mo和Se水平有显著影响。结果表明,在确定和解释陆龟血液微量元素水平时应考虑所有这些因素。
