What Are PFAS and PTFE? PFAS stands for per- and polyfluoroalkyl substances. They are a group of man-made chemicals that have been used in various industries since the 1940s. The PFAS group includes over 4,700 synthetic chemicals such as PFAS and PTFE, found in everyday items like cookware, clothing, and firefighting foam. Their resistance to…
Defining PFAS, PFOA, and PFOS Per- and polyfluoroalkyl substances (PFAS) include thousands of synthetic chemicals. Among these, PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate) are notable. These chemicals, known for their resistance to water, oil, and heat, have been widely used in applications such as non-stick cookware, stain-resistant fabrics, and waterproof clothing. While part of…
Per- and polyfluoroalkyl substances (PFAS) are a large group of human-made chemicals that have been widely used in industry and consumer products since the 1940s. Often referred to as “forever chemicals” due to their extreme persistence in the environment. PFAS have become a major focus of environmental and public health concern in recent decades as…
