What are PFAs and PFOAs?
Per- and polyfluoroalkyl substances (PFAs) are a group of human-made chemicals that have been used in various industries around the world since the 1940s. These substances are known for their resistance to water, grease, and stains, making them useful in a wide range of consumer products and industrial applications.
Perfluorooctanoic acid (PFOA) is one of the most well-known types of PFAs. It has been used in the manufacturing of non-stick cookware, water-resistant clothing, and stain-resistant fabrics and carpets. Despite their utility, PFAs and PFOAs have raised significant environmental and health concerns.
