A team of scientists has discovered a simple, low-energy way to break apart one of the largest groups of 'forever chemicals', nefarious pollutants that have been linked to environmental harm and human health concerns.
of what it considers to be 'safe' levels of PFAS contamination, as PFAS substances turned out to be more dangerous than regulators thought .of PFAS substances to exclude many forever chemicals.
Trang and colleagues tested their low-energy method on PFCA molecules of varying chain lengths, and managed to break down 10 of them. The trick was to target a group of charged oxygen atoms at the tail end of PFCA molecules. Using computer simulations to disentangle the cascade of complex chemical reactions and confirm the by-products were relatively harmless, the team are confident they are on to a good thing. Once destabilized, the molecules were stripped of nearly all of their fluorine atoms.
