PFOS was previously a component in fire foam until prohibited. It is very persistent in the environment and can accumulate in the food chain. Fire drill points are important point sources of the spread of highly fluorinated substances into the environment in Sweden.
Tests conducted by IVL Swedish Environmental Research Institutearound major Swedish airports show that highly fluorinated compounds known as PFAS continues to leak from the airports fire drill points into their surroundings.
RE-PATH is a five year research project with the intention to investigate and explain the occurrence, dispersion and risks for humans and the environment and to examine possible measurements regarding perfluorinated compounds around Swedish airports (Stockholm Arlanda Airport and Göteborg Landvetter Airport).
The research project is led by IVL Swedish Environmental Research Institute and funded by Swedavia Swedish Airports and the Swedish EPA.
