New technology using sunlight may help remove "forever chemicals" from the environment. Known as PFAS, these chemicals are hard to break down and are linked to health risks. They are found in non-stick cookware, waterproof clothing, and food packaging. The University of Bath in the UK has developed a system using sunlight to break PFAS into simpler substances.

The system uses a carbon-based catalyst with a polymer to attract PFAS molecules. This allows natural sunlight to break down the chemicals effectively. The technology could also help detect pollution and develop portable sensors for finding high PFAS levels.

Forever chemicals have been used since the 1940s due to their resistance to heat, water, and oil but degrade slowly. This raises environmental and health concerns, including cancer. Researchers believe the new method could help monitor and reduce PFAS pollution globally.
