A group of environmental scientists issued a warning Friday about commonly used chemicals known as PFASs. The chemicals, which go by the longer names of polyfluoroalkyl and perfluoroalkyl, are found in everything from pizza boxes to carpet treatments, reports the New York Times. “If you got a pastry with your coffee this morning, a PFAS substance probably even lined the waxy paper it was served on,” writes Lynne Peeples at the Huffington Post. (In the case of the pizza boxes, the chemicals help prevent the boxes from getting soaked by grease.)

The warning came May 1 in the journal Environmental Health Perspectives, whose coverage included a statement signed by 200 scientists from 38 countries urging restrictions. (It’s here, known as the Madrid Statement.) A previous type of PFAS, popularized by DuPont years ago in Teflon products, is no longer in use because of concerns the chemicals lingered in bodies and raised the risk of cancer.
