Stockholm Arlanda Airport as a source of per- and polyfluoroalkyl substances to water, sediment and fish.

Fire training facilities are potential sources of per- and polyfluoroalkyl substances (PFASs) to the nearby environment due to the usage of PFAS-containing aqueous fire-fighting foams (AFFFs). The multimedia distribution of perfluoroalkyl carboxylates (PFCAs), perfluoroalkyl sulfonates (PFSAs), perfluorooctanesulfonamide (PFOSA) and 6:2 fluorotelomer sulfonate (FTSA) was investigated near a fire training facility at Stockholm Arlanda Airport in Sweden. The whole body burden of PFASs in European perch ( Perca fluviatilis ) was 334 ± 80 μg absolute and was distributed as follows: Gonad > liver ≈ muscle > blood > gill. The bioconcentration factor (BCF) and sediment/water partition coefficient ( K d ) increased by 0.6–1.7 and 0.2–0.5 log units, respectively, for each additional CF 2 moiety for PFCAs and PFSAs. PFAS concentrations in water showed no significant decreasing trend between 2009 and 2013 ( p > 0.05), which indicates that Stockholm Arlanda Airport may be an important source for long-term contamination of the nearby environment with PFASs.
