Surface of glaciers is covered by mineral and organic dust, together with microorganisms
forming cryoconite granules. Despite fact that glaciers and ice sheets constitute significance …

This paper presents a detailed survey of the activities of selected man-made radionuclides
in peat deposits located in SW Spitsbergen. Peat cores from the High Arctic (SW …

Activity concentrations, inventories and activity ratios of 137 Cs, 238 Pu, 239+ 240 Pu and
241 Am in soil profiles were surveyed in the dry tundra and the adjoining proglacial zones of …

Plant ecosystem engineers are widely used to combat land degradation. However, the
ability of those plants to modulate limiting abiotic and biotic resources of other species can …

Several natural and anthropogenic radionuclides (210Pb, 226Ra and 137Cs) in guano-
phosphatic coral sediments and pure guano particles collected from Ganquan, Guangjin …

Heavy metals and radioactive compounds are potentially hazardous substances for plants,
animals and humans in the Arctic. A good knowledge of the spatial variation of these …

This article presents the results of studies of the activity of radionuclides in peat-bog profiles
of the European subarctic of Russia. Two peat profiles were collected in different areas of …

The Arctic region is substantially a pristine area, but this unique part of the globe has also
been contaminated by anthropogenic radioactive nuclides, and now there is still measurable …

The article presents the results of a study of activity levels and features of the vertical
distribution of 210Pb, 137Cs, 234U, 238U and their relationship with the physicochemical …

The research was focused on the level and distribution of 90 Sr in various parts of the
terrestrial environment of Spitsbergen. The mean activity concentrations were noted lower in …
