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, Canada These 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. The Northern Contaminants Program (NCP, http://www.science.gc.ca/eic/site/063.nsf/eng/h_7A463DBA.html) was established in 1991 in response to concerns about human exposure to elevated levels of contaminants in wildlife species that are important to the traditional diets of northern Aboriginal peoples. Early studies found a wide variety of substances, many of which had no Arctic or Canadian sources, but which were, nevertheless, reaching unexpectedly high levels in the Arctic ecosystem. The Canadian Cryospheric Information Network (CCIN, https://www.ccin.ca/) and the Polar Data Catalogue (PDC, https://polardata.ca/) have been developed over the past two decades through collaborative partnerships between the University of Waterloo and numerous government, university, and private organizations to provide the data and information management infrastructure for the Canadian cryospheric community. The PDC is one of Canada’s primary online sources for data and information about the Arctic and is Canada's National Antarctica Data Centre.
