Scientists home in on alternatives to ‘forever chemicals’

Scientists are developing alternatives to harmful "forever chemicals" known as PFAS. These chemicals, found in products like nonstick cookware and firefighting foam, persist in the environment and have been linked to health issues. Researchers have identified fluorine-free compounds that may replicate PFAS' water-repelling properties, though finding oil-repellent substitutes remains challenging. This work could help transition away from PFAS in some applications, potentially reducing environmental and health risks.
