| PFAS |
acronym for perflouroalkyl and polyflouroalkyl substances. Such chemical substances are used in a vast number of products and applications such as non-stick coatings for cookware, cleaning products, wire insulation, clothing, and food packaging. Some are known to be toxic, and, as a group, they are considered at least potentially harmful to human and animal health. They are also considered an environmental pollutant, as they can take thousands of years to break down, earning the the appellation "forever chemicals." |
