Because of their useful surfactant properties, per- and polyfluoroalkyl substances (PFAS) have been massively produced for non-stick coatings, water-repellant fabrics and firefighting foams. However, scientists have detected these highly stable 'forever chemicals' throughout the environment, prompting toxicity concerns. Now, researchers have characterized PFAS in contemporary and historical organic waste products applied to agricultural fields in France, finding the highest amounts in urban samples, with compounds changing over time.
