“…On the other hand, partitioning of trace elements depended on the sampling site position, showing a general decrease of the particulate fraction when moving from the coast to the plateau. In addition, samples from the plateau were characterized by higher enrichment factors of anthropogenic elements (Cd, Cr, Cu, Pb and Zn) compared to the coastal area, in good agreement with the results by Ikegawa et al (1999).…”

“…Ikegawa et al, 1999;Dahe et al, 1999;Grotti et al, 2011;Thamban and Thakur, 2013). In addition, the analysis of samples collected from snow pits (Boutron and Patterson, 1983;Planchon et al, 2002a,b;Hong et al, 2002;Hur et al, 2007;Fortner et al, 2011;Hong et al, 2012) provided important time-series or seasonal patterns of trace metal deposition to the snow.…”

“…In the surface snow, Ikegawa et al (1999) examined the geographical distribution of fallout flux of major and trace elements in East Queen Maud Land, Antarctica. Surface snow samples have been collected between 1991-1993 during oversnow traverses, and analyzed for a total of 37 major and trace elements.…”

“…Qomolangma samples, data of elemental concentration in precipitation from other regions in the world were cited and organized for comparison ( Table 2). The data include precipitation in remote polar regions, such as fresh snow from the Asuka site in Antarctica [20] , snow samples from the Atqasuk site in Artic [21] , snowpit samples (1991)(1992)(1993)(1994)(1995) collected from Central Greenland [22] and from the col of Rongbuk Glacier (6500 m a.s.l. ), fresh snow from different elevations from Chamonix Valley [16] in the Alps region and precipitation from Athens [23] which represents large cities influenced by intensive human activities.…”

A total of 14 surface snow (0-10 cm) samples were collected along the climbing route (6500-8844 m a.s.l.) on the northern slope of Mt. Qomolangma in May, 2005. Analysis of elemental concentrations in these samples showed that there are no clear trends for element variations with elevation due to redistribution of surface snow by strong winds during spring. In addition, local crustal aerosol inputs also have an influence on elemental composition of surface snow. Comparison between elemental concentration datasets of 2005 and 1997 indicated that data from 2005 were of higher quality. Elemental concentrations (especially for heavy metals) at Mt. Qomolangma are comparable with polar sites, and far lower than large cities. This indicates that anthropogenic activities and heavy metal pollution have little effect on the Mt. Qomolangma atmospheric environment, which can be representative of the background atmospheric environment.

“…Elemental geochemical studies are increasingly being used to interpret some of the information on the palaeoclimatic variability and anthropogenic pollution recorded in different materials of the Antarctic environment, such as snow-ice, soil and sediments (Boutron et al, 1986;Bishop et al, 1996;Ciaralli et al, 1998;Ikegawa et al, 1999;Giordano et al, 1999;Sheppard et al, 2000). To our knowledge, however, sediments influenced by seal excrements have rarely been studied with an elemental geochemical approach.…”

A preliminary study of elemental geochemistry and its potential application in Antarctic Seal palaeoecology

The elemental geochemical composition of sediments influenced by seal excrements in the Antarctic Fildes Peninsula has been examined in order to establish the source of organic matter, identify potential bio-elements and explore their potential palaeoecological implications. The combination of total organic carbon concentration (TOC), total nitrogen concentration (TN), organic carbon isotope (d 13 C) and atomic C/N ratio shows that the organic matter in the sediments with many seal hairs has a marine origin, predominantly derived from seal excrements. Among the determined element/ oxide concentrations, S, Se, F, Zn, Hg, FeO and P 2 O 5 were found to be remarkably enriched in the sediments influenced by seal excrements with respect to the sediments with few or without seal hairs, and their concentrations displayed strong and positive correlations with organic matter abundance, indicating that they had the same source and transportation mechanism as the in situ organic material. A comparison of these element/oxide concentrations with the seal hair numbers showed that they had similar distribution patterns with depth, and the correlations were positive and statistically significant. Based upon these results, S, Se, F, Zn, Hg, FeO and P 2 O 5 in the seal excrement sediments were identified as potential bio-elements and their concentrations could potentially be used as inorganic geochemical indicators for tracking seal palaeoecological processes in the Antarctic region.
