Livers of caribou and reindeer (Rangifer tarandus) from Canada (n = 146), Greenland 30), Svalbard 7), Sweden 60) were analyzed for concentrations eight perfluoroalkyl carboxylic acids four perfluoroalkane sulfonic acids. In Canadian caribou, PFNA (range < 0.01-7.4 ng/g wet weight, ww) PFUnDA (<0.01-5.6 dominated, whereas PFOS predominated in samples South Greenland, Svalbard, Sweden, although the highest found Southwest (up to 28 ww). We median all PFAS except PFHxS Akia-Maniitsoq (Southwest 7.2-19 ww, 15 The ΣPFAS also Akia-Maniitoq (101 followed by nearby Kangerlussuaq (45 ww), where largest airport is situated, along with a former military base. Decreasing trends seen one three Swedish populations. Furthermore, PFNA, PFDA, PFUnDA, PFDoDA, PFTrDA showed decreasing Canada's Porcupine between 2005 2016. increased Norrbotten 2003 2011. Västerbotten had higher lower 2010 compared 2002. Finally, we observed 2002 (albeit statistically insignificant) Jämtland, while no difference at all.
