Nonstick pans often rely on the repellant properties of per- and polyfluoroalkyl substances.

Last month, a group of scientists scored an unexpected win in chemical regulation: The state of Maine became the world’s first jurisdiction to ban the sale of products containing per- and polyfluoroalkyl substances (PFASs). The controversial chemicals are common in consumer goods such as nonstick cookware. By 2030, Maine will forbid selling products that use PFASs unless regulators determine their use is “currently unavoidable.”
