“…Pri/Phy ratios at the BCAA were close to or lower than one in all the sites measured, which may be related to the prevalence of reducing conditions in soil and sediments, besides petroleum inputs. The absence of pristane in several sites reinforced the likelihood of the occurrence of anoxic hydrocarbon biodegradation processes (Prus et al 2015). Site T11, adjacent to the generator room, and site T13, next to the fuel tanks, presented Pri/Phy ratios close to one, confirming the occurrence of oil pollution and weathered or degraded crude oil in these sites (e.g.…”

“…Hydrocarbon contamination of Antarctic soils and sediments has been demonstrated over recent years at a range of sites (e.g. Aislabie et al 1999, Martins et al 2004, Curtosi et al 2007, Bícego et al 2009, Dauner et al 2015, Prus et al 2015, despite the low human presence on the Antarctic continent. Logistical support for scientific operations, growing tourism and fisheries have been reported as the major sources of hydrocarbon pollution in Antarctica (Mazzera et al 1999, Curtosi et al 2007, Tin et al 2009.…”

“…The low temperatures occurring in Antarctica delay the biological degradation of hydrocarbons in contaminated soils, where they are generally highly persistent. However, information about the origin (biogenic or anthropogenic) of these compounds is also preserved under low temperature conditions, so potential sources can be investigated (Prus et al 2015, Cabrerizo et al 2016.…”

Hydrocarbons in soil and meltwater stream sediments near Artigas Antarctic Research Station: origin, sources and levels

et al. 2018

Aliphatic and polycyclic aromatic hydrocarbons (AHs and PAHs) were investigated in soil and meltwater stream sediments near the Uruguayan Artigas Research Station (BCAA). Gas chromatography with flame ionization detection and gas chromatography mass spectrometry were used to determine the composition of AHs and PAHs, respectively. Total AH concentrations were in the range 0.57–2333 µg g-1, while total PAH concentrations were in the range 1.36–51 650 ng g-1. Based on AH and PAH concentrations, sites in the service area and next to the boat storeroom are highly contaminated, while the other sites sampled have moderate to low contamination levels or are not impacted. High unresolved complex mixture concentrations indicate the occurrence of previous petrogenic contamination, but the dominance of low molecular weight and alkyl PAHs indicate recent oil introductions. Anthropogenic hydrocarbons dominate and are related to diesel fuel and organic residue combustion, fuel storage and boat traffic. Petrogenic contamination is relatively high, as at other Antarctic stations, but is restricted to the boat storeroom and the service area where the incinerator, the generator room and fuel tanks are located. Improvements made in fuel management procedures and the dismantling of the old fuel tanks will reduce the risk of diesel leaks and their impact on the environment near the BCAA. This study provides reference information for future environmental monitoring.

“…In the literature, there is a lack of data on the presence of n-alkanes in Antarctic freshwater samples. However, a previous study of geochemical markers of pollution in soil and terrestrial sediments from this area indicates that the distribution of inter alia n-alkanes mostly indicates that the organic matter present in sediments originates from petroleum product spills rather than from the Antarctic environment (Prus et al 2015 ). In their studies, sediments with relatively recent contamination recognised near Arctowski Polish Antarctic Station was the richest in short-chain n-alkanes.…”

Organic contamination in freshwater samples has never been investigated at the western shore of Admiralty Bay. Therefore, the presence of polycyclic aromatic hydrocarbons (PAHs) in five different sites distributed along a shore running from the Arctowski Station to the Baranowski Glacier was studied. Moreover, organic compounds such as n-alkanes, toluene and ethylbenzene were also noted. Increased ΣPAHs in late Austral summer 2016 are the result of long-range atmospheric transport of air masses from South America, confirmed by 10-day backward air mass trajectories analysis. The presence of n-alkanes and other hydrocarbons, as well as the evaluation of PAH indices (e.g. ΣLMW/ΣHMW* > 1), shows the use of fuel and indicate local human activity. As a final conclusion, our analysis indicates a mixed origin of PAHs (global and local). The presence of PAHs and other hydrocarbons in the water environment may constitute a potentially negative effect on the Antarctic ecosystem and it should be investigated in detail during further research (//*ΣLMW—sum of low molecular weight PAHs (two- and three-ring PAHs); ΣHMW—sum of high molecular weight PAHs (four- and five-ring PAHs)//).

“…Malandrino et al, 2009;Zheng et al, 2015). In an analogous manner, runoff water is known to have a key influence in marine primary production (Anderson and Polis, 1999) and in carrying trace elements (Bettinelli et al, 2000) to be absorbed by marine life (Cipro et al, 2018).. Several studies pointed the suitability of both soil (Prus et al, 2015;Sysalová et al, 2013) and vegetation as good indicator matrixes for both organic and inorganic contaminants (e.g. Lim et al, 2009;Wojtuń et al, 2013;Zvěřina et al, 2014) as well as some others that compare soil, lichens and/or mosses (e.g.…”

Seabird colonies as relevant sources of pollutants in Antarctic ecosystems: Part 1 - Trace elements

et al. 2018

Global distillation is classically pointed as the biggest responsible for contaminant inputs in Polar ecosystems. Mercury (Hg) and other trace elements (TEs) also present natural sources, whereas the biologically mediated input is typically ignored. However, bioaccumulation and biomagnification combined with the fact that seabirds gather in large numbers into large colonies and excrete on land might represent an important local TEs input. A previous work suggested these colonies as sources of not only nutrients, but also organic contaminants. To evaluate a similar hypothesis for TEs, samples of lichen (n = 55), mosses (n = 58) and soil (n = 37) were collected in 13 locations within the South Shetlands Archipelago during the austral summers of 2013-14 and 2014-15. They were divided in: "colony" (within the colony itself for soil and bordering it for vegetation) and "control" (at least 50 m away from colony interference), analysed for TEs (As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, V, and Zn) and stable isotopes (C and N). In most cases, soil seems the best matrix to assess colonies as TEs sources, as it presented more differences between control/colony sites than vegetation. Colonies are clearly local sources of organic matter, Cd, Hg and likely of As, Se and Zn. Conversely, Co, Cr, Ni and Pb come presumably from other sources, natural or anthropogenic. In general, isotopes were more useful for interpreting vegetation data due to fractionation of absorbed animal-derived organic matter. Other local Hg sources could be inferred from high levels in control sites, location and wind patterns.
