Résumé

In Arctic seabirds, positive correlations between per- and polyfluoroalkyl substances (PFAS) and thyroid hormones (THs) and resting metabolic rate (RMR) have been documented. Herein we investigated levels and patterns of PFAS in Arctic terns (Sterna paradisaea) nesting in Kongsfjorden, Svalbard (Norway), and if circulating concentrations of PFAS correlated with their circulating concentrations of TH and the RMR of the birds. The hypothesis was that there will be positive correlations between PFAS, TH, and RMR, indicating that PFAS-induced increases in plasma THs could be responsible for the increased RMR. The dominating PFAS in the terns were perfluorooctane sulfonate (PFOS), perfluoroundecanoate (PFUnDA) and perfluorotridecanoate (PFTrDA). The PFAS pattern was similar to what has been found in other seabirds in Kongsfjorden. There were positive correlations between several PFAS and total triiodothyronine (TT
