Per- and polyfluoroalkyl substances (PFASs) are a complex class of thousands of chemicals. They are of increasing concern due to their persistence, potential toxicity and ubiquitous abundance in the environment. Understanding and evaluating their emission pathways is essential to plan and implement effective measures to reduce emission of PFASs. In this project, funded by the Swiss Federal Office for the Environment (FOEN), the occurrence of PFASs in ambient air will be investigated. Sampling a broad range of PFASs simultaneously is challenging, as is their subsequent simultaneous analysis. This project aims at overcoming these challenges to reliably measure atmospheric levels of PFASs and model their respective emission strengths in Switzerland. The results are directly relevant to the FOEN and will support regulatory decisions regarding PFASs.
