Svalbard reindeer as an indicator of ecosystem changes in the Arctic terrestrial ecosystem

摘要: Abstract Over the years, noticeable effort has been directed towards contaminant determination in multiple biotic samples collected from inhabitants of Arctic. Little consideration given to polar herbivores, however, especially those European parts To provide a broader perspective, we aimed decipher trace element concentration hairs key species Arctic, namely Svalbard reindeer (Rangifer tarandus platyrhynchus), and recognise whether diet variations could correspond with forward exposure. The effect habitat was investigated using ratios stable isotopes carbon (δ13C) nitrogen (δ15N), previous literature studies on vegetation areas interest. Analysis performed for eighteen elements total, both toxic essential. Metals were present decreasing order Fe > Zn > Ba > Cu > Pb > Cr > Ni > V > Ga =La > Rb > As > Li > Co > Hg > Cd > Cs > Be. Similarity trends studied subpopulations observed many metals. A significant log-linear correlation most elements, excluding signature. Extremely high iron levels determined some samples, suggesting past overload. Zinc, contrast remaining metals, did not correlate well any other element. Mercury at very low levels, accordance regarding its concentrations moss lichen Svalbard. analysis showed variation signatures. Further research is required properly evaluate potential health risks ecological implications elevated
