Concentrations of perfluoroalkyl acids (PFAAs) in snow on the Devon Ice Cap, Nunavut, Canada

Concentrations of perfluoroalkyl acids (PFAAs) in snow on the Devon Ice Cap, Nunavut, CanadaThese datasets contains depth profile of perfluoroalkyl acids (PFAAs) concentrations collected from snow on the Devon Ice Cap from 2005-2015.

Perfluoroalkyl acids (PFAAs) are present in remote regions where no local sources exist. To improve understanding of long-range transport of perfluoroalkyl substances to the High Arctic, samples were collected from a snow pit on the Devon Ice Cap in spring 2005, 2006, 2008 and 2015. Snow was analyzed for perfluoroalkyl acids (PFAAs), including perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkyl sulfonic acids (PFSAs), as well as perfluorooctane sulfonamide (FOSA). Observations of PFAAs from these samples provide further evidence that atmospheric oxidation of volatile precursors is an important source of PFAAs to the Arctic environment.
