Perfluoroalkyl octanoic acid, commonly known as PFOA, is a synthetic chemical used in various industrial applications and consumer products. It is part of a larger group of chemicals called PFAS, which are known for their water- and grease-resistant properties. PFOA has been used in the production of non-stick cookware, stain-resistant fabrics, and food packaging. PFOA is concerning due to its persistence in the environment and potential health risks. Studies have linked exposure to PFOA with various health issues, including liver damage, immune system effects, and increased risk of certain cancers. As a result, many countries are working to reduce or eliminate the use of PFOA and other PFAS chemicals.
