“…These interspecies differences could be explained by the proximity to urban environments, which are associated with high PFAS levels [36]. However, common guillemot eggs collected in 2005 in an open sea distant from urbanized areas (Sklinna, Norway) also showed higher levels of PFOS than great skua, with a mean of 85 ng/g (range, 3-210 ng/g) [38].…”

Abstract-Temporal, biological, and environmental factors affecting accumulation of perfluoroalkyl substances (PFASs) are poorly understood in comparison with legacy lipid-soluble persistent organic pollutants. Temporal and biological comparisons of PFAS concentrations were made in great skuas (Stercorarius skua), a marine apex predator. Concentrations of 16 PFASs were quantified, including C4-C10 perfluorosulfonates (PFSAs), perfluorooctanesulfonamide (PFOSA), and C5-C14 perfluorocarboxylates (PFCAs). Concentrations of PFASs (ng/g wet wt) were significantly higher in eggs collected in Shetland in 2008 compared with 1980 for most compounds. However, the magnitude of the differences was small, with a mean increase of 3 ng/g. Levels of PFASs in great skuas were low compared with those of other seabirds in similar ecological niches; and in contrast to other contaminants measured in the same eggs, concentrations of PFASs did not correlate with trophic level. Concentrations of PFASs in adult plasma were significantly higher in males than in females for most PFASs. This suggests that maternal transfer through egg laying may be a significant mode of elimination of PFASs in female great skuas. The low concentrations of PFASs in eggs and plasma compared with other halogenated organic contaminants and other species suggest that great skuas do not bioaccumulate PFASs to the same extent as some other seabirds.

“…N-EtFOSA was only detected in guillemot eggs from North-Western Europe at low concentrations (o10 ng g À1 ww). [111] Influence of age and sex on PFCs in seabirds Age and sex specific differences in PFC concentrations in seabirds have not been observed in most of the studies. [25,94,110,113] Analyses of blood of breeding lesser black-backed gulls (Larus fuscus) from northern Norway resulted in lower concentrations of PFCs in females than in males, [118] which is probably caused by excretion of PFCs through laying eggs as discussed earlier.…”

“…[111] Additionally, the assessment of the global distribution is difficult because PFC concentrations in birds depend on the diet (significant higher PFOS concentrations were found in the livers of piscivorous birds than in non-piscivorous birds) [112] and therefore on their trophic levels, their specific bioaccumulation and elimination rates and on their migration pattern. Thus, the comparison of different species is problematic, as a consequence further investigations are necessary.…”

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.

“…PFOS and other PFSAs are widely distributed in the global environment [34][35][36][37][38], biota [39][40][41][42][43][44] and humans [15,[45][46][47][48][49][50][51][52]. Due to the dominance of POSF-based products historically, PFOS is usually the most abundant PFSA found.…”

Background: There is a concern that continued emissions of man-made per-and polyfluoroalkyl substances (PFASs) may cause environmental and human health effects. Now widespread in human populations and in the environment, several PFASs are also present in remote regions of the world, but the environmental transport and fate of PFASs are not well understood. Phasing out the manufacture of some types of PFASs started in 2000 and further regulatory and voluntary actions have followed. The objective of this review is to understand the effects of these actions on global scale PFAS concentrations.Methods: Searches for primary research studies reporting on temporal variations of PFAS concentrations were performed in bibliographic databases, on the internet, through stakeholder contacts and in review bibliographies. No time, document type, language or geographical constraints were applied in the searches. Relevant subjects included human and environmental samples. Two authors screened all retrieved articles. Dual screening of 10% of the articles was performed at title/abstract and full-text levels by all authors. Kappa tests were used to test consistency. Relevant articles were critically appraised by four reviewers, with double checking of 20% of the articles by a second reviewer. Meta-analysis of included temporal trends was considered but judged to not be appropriate. The trends were therefore discussed in a narrative synthesis.
