• Long-lasting environmental pollutants known as PFAS, or "forever chemicals," can remain in the environment for up to 1,000 years after being used. A team of researchers has developed a chemical system that uses light to break down the incredibly strong carbon-fluorine bonds that help PFAS resist degradation.

Researchers at the University of California, Riverside, have developed a novel method to degrade PFAS (Per- and polyfluoroalkyl substances), known as "forever chemicals" due to their environmental persistence. These chemicals, found in various products from non-stick cookware to firefighting foam, are notorious for not breaking down naturally. The new technique involves using a combination of UV light and a special catalyst, sulfite, to initiate a process that effectively breaks the strong carbon-fluorine bonds in PFAS. This method, which was detailed in a study published in the journal "Environmental Science & Technology," could potentially offer a scalable solution for treating PFAS-contaminated water, reducing the environmental and health risks associated with these compounds. The approach not only promises to be cost-effective but also environmentally friendly, as it avoids the use of harsh chemicals or high energy inputs.
