Accurate Determination of Trace Gallium in Antarctic Terrestrial Flora using Electrothermal Atomic Absorption Spectrometry

Popis výsledku v původním jazyce

Gallium is a technology-critical element whose concentration increases owing to industrial activity. To study anthropogenic contamination in maritime Antarctica (Nelson Island, South Shetland Islands), it was necessary to develop an analytical method to determine the trace Ga content in Antarctic flora. The determination of Ga using electrothermal atomic absorption spectrometry (ETAAS) is a seemingly routine analytical task; however, the commonly used atomic lines of 287.4?nm and 294.4?nm appear to be unsuitable for analytical use. In this study, the fundamental aspects of Ga determination were investigated, and an atomic line at a wavelength of 417.2?nm was recommended for the analysis of environmental samples. The Ga content in mosses, lichens, mushrooms, and grass samples from Antarctica are published here for the first time. Based on the Ga content of lichens as biomonitors of atmospheric pollution, it can be assumed that contamination of the studied locality through atmospheric deposition is low.
