Abstract Urbanization and the continued encroachment of human activity into green spaces often result in the decline of several animal species. Macroclemys temminckii (alligator snapping turtle) is particularly sensitive to human activity as it is an opportunistic scavenger and carnivore. The longevity of this species, as well as its dietary habits make it an excellent candidate for biomonitoring. In this preliminary study, twelve (12) shell samples were collected from individuals trapped at Fort Polk, LA and Sam Houston Jones State Park, LA. Inductively coupled plasma optical emission spectroscopy (ICP-OES) was used to determine the presence of the toxic metals cadmium (Cd), chromium (Cr) and lead (Pb) in addition to other trace minerals and iron (Fe). The levels of the toxic metal were below the detection limit of the ICP-OES. This report represents the first study of this nature on Macroclemys temminckii.

电感耦合等离子体光发射光谱法测定短吻鳄龟（Macroclemys temminckii）中选定的金属

摘要 城市化和人类活动对绿色空间的持续侵占往往导致几种动物物种的减少。Macroclemys temminckii（鳄鱼鳄龟）对人类活动特别敏感，因为它是一种机会主义的清道夫和食肉动物。该物种的长寿及其饮食习惯使其成为生物监测的绝佳候选者。在这项初步研究中，从被困在洛杉矶波尔克堡和洛杉矶萨姆休斯顿琼斯州立公园的个人身上收集了十二 (12) 个贝壳样本。电感耦合等离子体发射光谱 (ICP-OES) 用于确定有毒金属镉 (Cd)、铬 (Cr) 和铅 (Pb) 以及其他微量矿物质和铁 (Fe) 的存在。有毒金属的含量低于 ICP-OES 的检测限。
