A 50 year record for perfluoroalkyl acids in the high arctic: implications for global and local transport

An ice core dated 1967–2016 represents the longest Arctic deposition record for perfluoroalkylcarboxylic acids (PFCAs) and the longest global record of perfluoroalkylsulfonic acids (PFSAs), providing unique insights into their long-range transport.
