“…Those birds were also high contaminated with PFOS and in one case with PFOA, indicating several sources of exposure. [94,114] FTCAs were not found in seabirds. [106] But the corresponding unsaturated acids, 8 : 2 and 10 : 2 FTUCAs, were detected in some individuals at very low concentrations.…”

“…[106] Considerable amounts of PFOS were reported in spleen and in feathers (31-247 ng g À1 dw) compared to birdś livers (12-476 ng g À1 ww). [114] It was concluded that the deposition of PFOS in the feathers might be an important elimination route for PFOS in birds. In another study the authors reported higher PFOS levels in the spleen (6.2-131.5 ng g À1 ww) than in the liver (4.0-55.7 ng g À1 ww) of brown pelicans (Pelecanus occidentalis) followed by moderate concentrations in lung, kidney and brain (1.2-17.3 ng g À1 ww) and lowest concentrations in heart and muscle (o7 ng g À1 ww).…”

Environmental context. Polyfluoroalkyl compounds are used in a variety of industrial and consumer applications, including polymer production and for surface treatment of textiles and paper. Research over the last 10 years has shown that these compounds are ubiquitous environmental contaminants -they are extremely persistent, show toxic effects and accumulate in the food chain. We evaluate global, temporal and spatial trends of these important emerging contaminants.Abstract. This review gives an overview of existing knowledge of polyfluoroalkyl compounds (PFCs) in humans and in marine biota. Temporal trends and spatial distribution of PFCs were globally compared in humans, marine mammals, seabirds and fish. In general, PFC concentrations in the environment have increased significantly from the beginning of the production up to the 1990s. After the phase-out of perfluorooctane sulfonyl fluoride (POSF) production starting in 2000, PFC concentrations in humans generally decreased. In marine biota no clear temporal trends were observed. The temporal trends depended on the species, their trophic levels and the geographical locations. PFC patterns in humans and in marine wildlife species were compared regarding perfluorooctane sulfonate (PFOS), perfluorooctanoate (PFOA), their shorter and longer chain homologues (C 4 -C 15 ) and precursor compounds. Finally knowledge gaps were identified and recommendations for future work were presented.

“…This corresponds to a concentration of 67 AE 26 mg kg À1 . Assuming that the remaining 15 % of the bird's tissue are equally contaminated, [49] the total PFC body burden can be estimated to be 100 mg or 67 mg kg À1 .…”

Environmental context. Perfluorinated compounds are commonly used chemicals that are detected globally in all environmental matrices. We investigated the extent of contamination by perfluorinated compounds in the red-throated diver, a marine predatory bird, and observed an unusual distribution of perfluorinated compounds in tissues. The data help us to better understand the behaviour of these contaminants in organisms.Abstract. Twenty poly-and perfluorinated compounds (PFCs) were investigated in four red-throated divers (Gavia stellata) from the German Baltic Sea sampled in 2005. Concentrations of perfluoroalkyl sulfonates (PFSAs), perfluoroalkyl carboxylates (PFCAs), alkylated perfluoroalkyl sulfonamides, alkylated perfluoroalkyl sulfonamidoethanols and perfluorooctane sulfonamides were determined in blood, brain, fatty tissue, gall bladder, heart, kidney, liver, lung, muscle and spleen by high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). For quantification standard addition was applied. Twelve compounds were detected with average total PFC concentrations ranging from 42 ng g À1 in muscle to 220 ng g À1 in liver samples. Perfluorooctane sulfonate (PFOS) was the major compound in each of the 40 tissue samples. Except for brain, perfluoroundecanoate was the dominant PFCA. In brain samples preferential enrichment of long-chain PFSAs and PFCAs was observed. The total PFC body burden was estimated to 100 AE 39 mg. Multivariate statistical analyses supported the identification of the preferred accumulation 'location' of individual PFCs in the birds' body.

Accumulation of persistent organic pollutants (POPs) in wildlife may be influenced by the physical and biotic environment, and concentrations vary greatly among areas, seasons, and individuals. Different hypotheses about sources of variation in perfluoroalkyl substance (PFAS) concentrations were examined in eggs (n = 107) of tawny owls (Strix aluco) collected over a 24-yr period (1986-2009) in Norway. Predictor variables included the North Atlantic Oscillation (NAO), temperature, snow, food availability (vole abundance), and individual traits such as age, body condition, and clutch size. Concentrations of both perfluoro-octane sulfonate (PFOS) and perfluoroalkyl carboxylates (PFCAs) varied several fold in the population, both inter- and intra-annually. Moreover, individuals laid eggs with several times higher or lower PFAS concentrations within few years (1 yr-5 yr). After controlling for temporal trends (i.e., declining PFOS and increasing PFCA concentrations), both PFOS and PFCAs were positively associated to the winter NAO in the previous year (NAOy - 1 ), suggesting that atmospheric transport may be affecting the input of PFASs to the local ecosystem. Perfluoro-octane sulfonate was negatively related to temperature, but the pattern was complex as there was an interaction between temperature and the feeding conditions. The PFOS accumulation was highest in years with high vole abundance and low to medium temperatures. For PFCAs, there was an interaction between NAOy - 1 and feeding conditions, suggesting that strong air transport toward Norway and high consumption of voles led to a moderate increase in PFCA accumulation. The individual traits, however, had very little impact on the concentrations of PFASs in the eggs. The present study thus suggests that annual variation in environmental conditions influences the concentrations of PFASs in a terrestrial raptor such as the tawny owl.
