These are per- and polyfluoroalkyl chemical substances that are made up of chemicals that accumulate over time in people, animals and the environment. They are considered both “everywhere chemicals” because they are used in many products and “forever chemicals” because they do not break down. For example, PFAS have been used in fabric, household cleaning supplies and stain-resistant carpet. These chemicals are endocrine disruptors known to interfere with human hormone systems and cause disease and, eventually, death. Studies published by the National Library of Medicine show that PFAS are in the blood of nearly all residents in the U.S. Other studies also show that PFAS impacts unborn babies.
