Environmental pollutants and their effect on wildlife health play an important role in the conservation of endangered species and can be clinically relevant in captive animals too. Data on relevant concentrations of trace elements in captive birds with no known exposures are rare. For this study, silver, arsenic, gold, barium, cadmium, cobalt, chromium, copper, iron, mercury, magnesium, manganese, molybdenum, thallium, selenium, and zinc were measured by inductively coupled plasma mass spectrometry in lithium heparinized plasma samples from 18 Humboldt penguins at 2 zoological collections in Germany. The results showed that the plasma concentrations of silver, arsenic, gold, cadmium, cobalt, chromium, mercury, and selenium differed significantly ( ≤ 0.05) between the 2 penguin collections. The results indicate that the location of the birds has a strong influence on the plasma trace element concentrations. Well water used in the enclosures was suspected to be associated with these significant differences. Trace elemental concentrations in feed (eg, marine fish) and contamination from enclosure construction materials may also play a role. This study could provide a basis for further comparative, biomonitoring, toxicity, and reference interval studies.
环境污染物及其对野生动物健康的影响在濒危物种保护中起着重要作用，在圈养动物中也具有临床相关性。关于没有已知暴露的圈养鸟类中微量元素相关浓度的数据很少。在这项研究中，对来自德国两个动物园收集的 18 只洪堡企鹅的锂肝素化血浆样本进行了电感耦合等离子体质谱法测量，以检测银、砷、金、钡、镉、钴、铬、铜、铁、汞、镁、锰、钼、铊、硒和锌。结果表明，两个企鹅群体之间的血浆银、砷、金、镉、钴、铬、汞和硒浓度存在显著差异（≤0.05）。结果表明，鸟类的位置对血浆微量元素浓度有强烈影响。怀疑圈舍中使用的井水与这些显著差异有关。饲料（如海洋鱼类）中的微量元素浓度和圈舍建筑材料的污染也可能起作用。本研究可为进一步的比较、生物监测、毒性和参考区间研究提供基础。
