Most people carry remnants of a chemical pollutant – ultrasound technology can help clean it up

Unfortunately, the same properties that make PFAS so useful, such as their durability, also make them infuriatingly stubborn to safely and sustainably dispose of. Scientists are working on a variety of ways to treat PFAS pollution, but many of these cannot completely destroy the carbon-fluorine chain. Teflon (or polytetrafluoroethylene) was the first PFAS invented, created accidentally by Roy Plunkett in 1938.
