2020 Devonport Airport. 

Eel samples at Devonport Airport gave detects for PFOS and PFHxS. The sample location on
Airport land, down/cross gradient of the fire training ground, reported around double the FSANZ criterion for PFOS+PFHxS in eels. The two other locations sampled in the vicinity of the airport were further from the coast. These locations gave detects for PFOS; samples were from farm dams up to 3 km from the fire training ground. The closest dam to the airport gave results that were equal to the criterion and the farthest about double. Therefore, there are no clear trends in relation to proximity to the airport.
