摘要: Abstract In this study, the presence of 18 perfluorinated compounds was investigated in biota and environmental samples from Antarctica Tierra de Fuego, which were collected during a sampling campaign carried out along February March 2010. 61 analysed including fish, superficial soils, guano, algae, dung tissues Papua penguin by liquid chromatography coupled to tandem mass spectrometry. The concentrations PFCs ranging 0.10 240 ng/g for most except dung, presented levels between 95 603 ng/g perfluorooctane sulfonate, guano Ushuaia, with concentration 1190–2480 ng/g perfluorohexanoic acid. acids presented, general, highest perfluorooctanesulfonate frequently found compound. present study provides significant amount results, globally supports previous studies, related transport, deposition, biodegradation bioaccumulation patterns PFCs.
