EEB | PFASs: Avoiding the streetlight effect

Per- and polyfluoroalkyl substances, commonly known as PFASs, are receiving increased regulatory attention because of their persistence and (eco)toxicological profile, as well as their widespread use and resulting ubiquitous presence.

In this report, we have used REACH registrations of PFASs, independent literature, technical information from producers and general chemical knowledge to sketch the landscape of which types of PFASs are most prevalent in products and likely lead to highest environmental pressures.

We conclude that the types of PFASs one should most care about are: fluorotelomer substances (FTs) and the side-chain fluorinated polymers (SCFPs) they give rise to, as well as fluorinated (poly)ethers.
