A study led by the Joe C. Wen School of Population & Public Health at the University of California, Irvine has revealed possible links between exposure to per- and polyfluoroalkyl substances in drinking water and an increased risk of certain childhood cancers. Widely used in industrial and consumer products, PFAS — commonly known as “forever chemicals” due to their persistence in the environment — have been linked to various adverse health effects. … In an online study in the journal Environmental Epidemiology, the researchers investigated the role that PFAS exposure via drinking water contamination may play in childhood cancer risk.
