Abstract

The article contributes to the study of the content of major and trace elements in various types of natural waters of the Broknes Peninsula, Larsemann Hills, Antarctica collected in January–February 2014 and 2020 during the 7th and 12th Belarusian Antarctic Expeditions. Samples of old (13 samples) and newly fallen snow (5), lakes (23) and groundwater (8) were analyzed. The content of 25 major and trace elements was determined using ICP-MS method, main anions was determined by titrimetric and turbidimetric methods. Good similarity chemical composition of snow, groundwater and lake waters in spite of differences in the content of major ions and trace elements has been obtained. The influence of marine salts on natural waters are analyzed, and their accumulation in lake waters especially in the endorheic small and shallow lakes in spite of ultra-oligotrophic atmospheric precipitates are shown. The spatial heterogeneity of groundwater and temporal and spatial heterogeneity of lake waters have been demonstrated. The results are important for understanding the variabilities of major and trace elements content in snow, groundwater and lake waters, and their relationship, as well as for identifying trends in their change, taking into account anthropogenic loads in the region and climate change.
