Recent environmental surveys have ascertained thewidespread occurrence of perfluorinated alkyl substances(PFAS) in tissues of wildlife from the Arctic. In thepresent study, we investigated the distribution of a suiteof PFAS in plasma, liver, brain, and egg samples from adultglaucous gulls (Larus hyperboreus), an apex scavenger-predator seabird breeding in the Norwegian Arctic.Perfluorooctane sulfonate (PFOS) was the predominantPFAS in all samples and was present at concentrations thatare the highest reported thus far in any arctic seabirdspecies and populations. Among the body compartment/tissue samples analyzed, PFOS was highest in plasma (48.1-349 ng/g wet weight (ww)), followed by liver 
egg >brain. Perfluorocarboxylic acids (PFCAs) with 8-15 carbon(C) atoms were found, with the highest concentrationsdetermined in plasma (sum PFCA: 41.8-262 ng/g ww),whereas 5C- and 6C-PFCAs were below the limits of detection.Perfluorobutane sulfonate, perfluorooctane sulfonamide,and four saturated (8:2 FTCA and 10:2 FTCA) and unsaturated(8:2 FTUCA and 10:2 FTUCA) fluorotelomer carboxylicacids were not detected in any samples. Perfluorohexanesulfonate was measured at concentrations up to 2.71ng/g ww. The accumulation profiles of PFCAs werecharacterized by high proportions of the long and odd-numbered carbon-chain-length compounds, namelyperfluoroundecanoic (11C) and perfluorotridecanoic acid(13C), although their individual contribution differed betweenthe matrixes analyzed. Current PFAS concentrationssuggest a bioaccumulation potential in Norwegian arcticglaucous gulls that needs to be assessed as part of a broadorganohalogen contaminant cocktail with potential formediating biological processes in this vulnerable top-predatormarine species.
