24 Aug 2022 --- Northwestern University chemists have developed a method – using low temperatures and inexpensive, common reagents – that causes two major classes of PFAS compounds to fall apart, leaving behind only benign end products. PFAS, also known as “forever chemicals,” are a class of synthetic compounds that have been employed extensively since the 1940s. They cannot be broken down by bacteria, incinerated by fire or diluted by water. If these dangerous substances are buried, they seep into the soil and remain a hazard for future generations.
