A Swiss study measures the populationʹs exposure to PFAS

They're invisible, highly resistant, and already present in our bodies. PFASs, also nicknamed "eternal pollutants", have been used for decades in many everyday objects: non-stick pans, waterproof textiles, food packaging or even fire-fighting foams. Their distinctive feature is that they persist for a very long time not only in the environment, but also in the human body.
