PFAS properties

PFAS are synthetic substances widely used in industry and everyday products due to their unique properties.

The name Per- and Polyfluoroalkyl Substances reveals key details about their chemical structure.'Alkyl Substance' refers to a carbon-chain backbone. “Per- and Polyfluoro-” indicates the presence of fluorine atoms, either at every available position of the carbon chain (Per-) or only at some (Poly-).

But why is it important to understand these substances? Four international experts—Hannela Artus, Patrick van Hees, Ulrike Braun, and Tommy Johansson - discuss the properties of PFAS, their industrial value, and the challenges they pose.
