In this study, the presence of 18 perfluorinated compounds was investigated in biota and environmental samples from the Antarctica and Tierra de Fuego, which were collected during a sampling campaign carried out along February and March 2010.61 samples were analysed including fish, superficial soils, guano, algae, dung and tissues of Papua penguin by liquid chromatography coupled to tandem mass spectrometry.The concentrations of PFCs were ranging from 0.10 to 240Â ng/g for most of the samples except for penguin dung, which presented levels between 95 and 603Â ng/g for perfluorooctane sulfonate, and guano samples from Ushuaia, with concentration levels of 1190-2480Â ng/g of perfluorohexanoic acid. PFCs acids presented, in general, the highest levels of concentration and perfluorooctanesulfonate was the most frequently found compound.The present study provides a significant amount of results, which globally supports the previous studies, related to the transport, deposition, biodegradation and bioaccumulation patterns of PFCs.
⺠61 samples from the Antarctica and Tierra de Fuego analysed for the presence of 18 perfluorinated compounds. ⺠Acid compounds presented the highest levels of concentration and perfluorooctane sulfonate was the most frequently found. ⺠Concentrations in algae much higher than those in soils. ⺠Data supporting existing models for the transport, deposition, biodegradation and bioaccumulation patterns are presented.
