Determination of selected metals in alligator snapping turtle (Macroclemys temminckii) by inductively coupled plasma-optical emission spectrometry

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. (C) 2017 Elsevier B.V.
