“…Thus, the PFAS pattern of Antarctic petrel adults likely reflects PFAS accumulation from fish, while the chick's PFAS pattern likely reflects PFAS accumulation from krill. The high content of PFUnA has also been found in fish-eating seabirds from other regions such as Spanish breeding colonies (Escoruela et al, 2018;Colomer-Vidal et al, 2022). The higher PFAS concentration in chicks than adults suggests that krill in Antarctica has relatively high PFAS concentrations and/or that maternal transfer to the egg is efficient.…”

Per and polyfluoroalkyl substances (PFASs) are found in Antarctic wildlife, with high levels in the avian top predator south polar skua (Catharacta maccormicki). As increasing PFAS concentrations were found in the south polar skua during the breeding season in Antarctica, we hypothesised that available prey during the breeding period contributes significantly to the PFAS contamination in skuas. To test this, we compared PFAS in south polar skuas and their main prey from two breeding sites on opposite sides of the Antarctic continent: Antarctic petrel (Thalassoica antarctica) stomach content, eggs, chicks, and adults from Svarthamaren in Dronning Maud Land and Adélie penguin chicks (Pygoscelis adeliae) from Dumont d’Urville in Adélie Land. Of the 22 PFAS analysed, seven were present in the majority of samples, except petrel stomach content [only perfluoroundecanoate (PFUnA) present] and Adélie penguins (only four compounds present), with increasing concentrations from the prey to the skuas. The biomagnification factors (BMFs) were higher at Dumont d’Urville than Svarthamaren. When adjusted to reflect one trophic level difference, the BMFs at Svarthamaren remained the same, whereas the ones at Dumont d’Urville doubled. At both the colonies, the skua PFAS pattern was dominated by perfluorooctanesulfonic acid (PFOS), followed by PFUnA, but differed with the presence of branched PFOS and perfluorotetradecanoate (PFTeA) and lack of perfluorononanoate (PFNA) and perfluorodecanoate (PFDA) at Dumont d’Urville. At Svarthamaren, the pattern in the prey was comparable to the skuas, but with a higher relative contribution of PFTeA in prey. At Dumont d’Urville, the pattern in the prey differed from the skuas, with the domination of PFUnA and the general lack of PFOS in prey. Even though the PFAS levels are low in Antarctic year-round resident prey, the three lines of evidence (pattern, BMF difference, and BMF adjusted to one trophic level) suggest that the Antarctic petrel are the significant source of PFAS in the Svarthamaren skuas, whereas the skuas in Dumont d’Urville have other important sources to PFAS than Adélie penguin, either in the continent or external on the inter-breeding foraging grounds far from Antarctica.

“…Characterizing the relationship between the concentration of per- and polyfluoroalkyl substances (PFASs) in the environment and the body burden in wildlife can be difficult in the field due to the spatial and temporal variability of species, sampling ability, and measurement of trace contaminant levels . Long-term changes in emissions of PFASs to the environment further influence the variability for exposure to wildlife . Typically, the field-based bioaccumulation factors (BAF) for PFASs in fish, marine mammals, and birds rely on steady-state assumptions of a species’ spatial and temporal variability, but these are often confounded by large foraging ranges .…”

The field-based distribution and bioaccumulation factor (BAF) for per- and polyfluoroalkyl substances (PFASs) were determined in residential Black Swans (Cygnus atratus) from an urban lake (Melbourne, Australia). The concentrations of 46 aliphatic and cyclic PFASs were determined by HPLC-MS/MS in serum and excrement from swans, and water, sediment, aquatic macrophytes, soil, and grass samples in and around the lake. Elevated concentrations of ∑46PFASs were detected in serum (120 ng mL–1) and excrement (110 ng g–1 dw) were strongly related indicating a potential noninvasive sampling methodology. Environmental concentrations of PFASs were consistent with a highly impacted ecosystem and notably high concentrations of perfluoro-4-ethylcyclohexanesulfonate (PFECHS, 67584–42–3; C8HF15SO3) were detected in water (27 ng L–1) and swan serum (16 ng mL–1). In the absence of credible putative alternative sources of PFECHS input to the lake, we propose that the use of high-performance motorsport vehicles is a likely source of contamination to this ecosystem. The BAF of perfluorocarboxylic acids increased with each additional CF2 moiety from PFOA (15.7 L kg–1 ww) to PFDoDA (3615 L kg–1 ww). The BAF of PFECHS was estimated as 593 L kg–1 ww, which is lower compared with that of PFOS (1097 L kg–1 ww).

“…The extraction method was adapted from a previous study analyzing PFASs in gull eggs (Colomer-Vidal et al, 2022). Briefly, 50 mg of whole freeze-dried blood were placed in a 2 mL polypropylene Eppendorf vial (Eppendorf, Hamburg, Germany), spiked with 50 ng of M-PFOA and M-PFOS and 1.5 mL of acetonitrile were added.…”

“…There are very few studies on PFASs in bird's blood from the Ebro Delta to compare our results with. PFASs, predominantly PFOS, PFUnA and PFTriDA, have been reported in eggs from yellow-legged gull (Larus michahellis) and Audouin's gull (Larus audouinii) from the Ebro Delta at higher concentrations compared to other natural parks from the Iberian peninsula (Colomer-Vidal et al, 2022). PFOS was detected in blood from Larus michahellis and Larus audouinii adults at mean concentrations of 46.8 ng/mL (from 8.92 to 142 ng/mL) and 45.5 ng/mL (from 27.4 to 107 ng/mL), respectively (Bertolero et al, 2015).…”
