It’s rare to find encouraging news about PFAS, a class of widely used “forever chemicals” that are linked to a range of health problems and don’t break down in nature. So when a study came out last week demonstrating a method to destroy PFAS, we reached out to Michigan State University biochemist A. Daniel Jones and soil scientist Hui Li to explain its potential. Their article provides an excellent description of why, on a chemical level, these substances are so challenging to contain and outlines some of the efforts researchers are pursuing to control this environmental health hazard.
