We speak to Professor Heather Stapleton and Dr. Nicholas Herkert about their latest research that led to the discovery of high levels of PFAS in anti-fogging sprays.
The anti-fogging sprays and cloths many people use to prevent condensation on their eyeglasses when wearing a mask or face shield may contain high levels of per- and polyfluorinated alkyl substances (PFAS), a new Duke University-led study finds.
New research has revealed the presence of toxic forever chemicals in yet another product: the anti-fogging sprays and cloths that people are using more and more frequently to keep their glasses from clouding over while wearing face masks. A Duke University-led research team found two types of under-studied per- and polyfluorinated alkyl substances (PFAS) in nine of the top-rated anti-fogging sprays and cloths sold on Amazon.
