Název v původním jazyce

Indium, Thallium, Antimony, and Bismuth in Antarctic Lichens from the Antarctic Peninsula Region

Popis výsledku v původním jazyce

The fragile Antarctic ecosystem is now more threatened by anthropogenic impacts than ever before, particularly in maritime Antarctica. Technology-critical elements (TCEs) produced by industrial activities can reach Antarctica by long-range atmospheric transport. This study aimed to determine the contents of indium, thallium, antimony, and bismuth in lichens from Deception Island, King George Island, Livingston Island, Nelson Island, Horseshoe Island, and James Ross Island, in order to identify potential contaminants. An analytical method employing high-resolution continuum source hydride generation atomic absorption spectrometry (HR-CS HGAAS) with a detection limit of 0.002 mg kg-1 was developed for the precise determination of bismuth. The highest observed contents of In, Tl, Sb, and Bi were 0.44 mg kg-1, 0.018 mg kg-1, 0.257 mg kg-1, and 0.011 mg kg-1, respectively. Knowing the current state of metal levels in this area is important for further research owing to the minimal clarification of the deposition and fate of TCEs in Antarctica.
