So-called “forever” chemicals are being consumed by people on a daily basis from a variety of ordinary materials, revealed a new report. In a study published in Environmental Science and Technology, researchers from the University of Toronto, Indiana University and the University of Notre Dame examined 42 different types of food packaging samples and found the presence of pre-and polyfluoroalkyl substances (PFAS), also known as “forever chemicals” in 55 per cent of the samples taken.
