“…Soils developed from volcanic rocks on Potter Peninsula showed variable values of bioavailable macroand micronutrients (Table 3). As expected for a higher plant, D. antarctica showed the highest mean values for Ca, Zn, Fe and Mn (Table 4), whereas P, K, Mg and Cu were comparable to reference values from elsewhere in the same region (Simas, 2006;Schaefer, C. E. G. R. et al, 2004;Poblet et al, 1997). D. antarctica showed the highest values of all elements, possibly because it is closely associated with ornithogenic soils.…”

“…The mean total values of Ca, Mg, Fe, Zn and Mn were similar to those reported in previous works in maritime Antarctica (Table 5). However, the values of P, K, Cu obtained in the present study were higher than those reported in the literature (Simas, 2006;Poblet et al, 1997;Allen et al, 1967;Tatur et al, 1997). In general, most elements had a wide range of values depending on the site characteristics and the age of plant communities.…”

Abstract. Integrated studies on the interplay between soils, periglacial geomorphology and plant communities are crucial for the understanding of climate change effects on terrestrial ecosystems of maritime Antarctica, one of the most sensitive areas to global warming. Knowledge on physical environmental factors that influence plant communities can greatly benefit studies on the monitoring of climate change in maritime Antarctica, where new ice-free areas are being constantly exposed, allowing plant growth and organic carbon inputs. The relationship between topography, plant communities and soils was investigated on Potter Peninsula, King George Island, maritime Antarctica. We mapped the occurrence and distribution of plant communities and identified soil-landform-vegetation relationships. The vegetation map was obtained by classification of a QuickBird image, coupled with detailed landform and characterization of 18 soil profiles. The sub-formations were identified and classified, and we also determined the total elemental composition of lichens, mosses and grasses. Plant communities on Potter Peninsula occupy 23 % of the ice-free area, at different landscape positions, showing decreasing diversity and biomass from the coastal zone to inland areas where sub-desert conditions prevail. There is a clear dependency between landform and vegetated soils. Soils that have greater moisture or are poorly drained, and with acid to neutral pH, are favourable for moss sub-formations. Saline, organic-matterrich ornithogenic soils of former penguin rookeries have greater biomass and diversity, with mixed associations of mosses and grasses, while stable felsenmeers and flat rocky cryoplanation surfaces are the preferred sites for Usnea and Himantormia lugubris lichens at the highest surface. Lichens sub-formations cover the largest vegetated area, showing varying associations with mosses.

“…The cape area near King Sejong Station is populated by flying seabirds, such as skuas. Previous studies have reported heavy metal concentrations in different components of King George Island, including snow-ice (Hong et al, 2002), soil (Choi et al, 2011;Santos et al, 2005), sediments (Andrade et al, 2001;Santos et al, 2005), and vegetation (Cho et al, 2008ab;Poblet et al, 1997;Hong et al, 1999;Osyczka et al, 2007). The purpose of this study was to investigate distribution characteristics of heavy metals in soil of vicinity of King Sejong Station on Barton Peninsula of King George Island, Antartica.…”

These authors equally contributed to this paperTo investigate distribution characteristics of heavy metals in soils in the vicinity of King Sejong Station of King George Island, Antarctica, Fe, Mn, Cu, Zn, Pb, Co, Cd, Cr, Ni and Mo contents were investigated under different distances and directions from King Sejong Station. 13 sample sites were distributed from King Sejong Station. In site 4, the Cd content was higher than that in other sites. The Cr content was the highest in site 9, and the Ni and Mn contents were high in site 12. Cu, Co and Zn were highly contained in distance 1~2 km from King Sejong Station. Cd, Cr, Ni and Mo contents were lower, whereas Fe, Mn, Cu, Zn, Pb and Co contents were higher than other heavy metal contents at all sites.

Despite the fact that Antarctica is a continent notably free from large negative impact of human activities, literature data can be the basis for concluding that this is not an area free from anthropogenic pollutants. Pollutants, which are identified in various elements of the environment of Antarctica, are mostly connected with long-range atmospheric transport (LRAT) and deposition in this area. The study presents: a historical overview of research pertaining to the presence of pollutants in entire Antarctica; a description of the development of research on pollutants in various environmental samples conducted in this area since 1960; a detailed description of contemporary analytical research (2000-2014); information on concentration levels of a broad range of pollutants present in various elements of the environment. The data collected can provide grounds for concluding that pollutants present in this area can contribute to gradual degradation of Antarctic ecosystem.
