PFAS - What are they? and How are they being regulated?
What are PFAS? PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances) are a group of over 10,000 synthetic fluorinated compounds that contain extremely strong carbon-fluorine bonds. Due to these properties, PFAS are resistant to thermal and chemical degradation, making them useful in various industrial applications and consumer products. Properties and Uses PFAS are used in products such as: Non-stick and stain-resistant coatings (pans, clothing, furniture) Firefighting foams Lipophobic packaging (fast food containers, pizza boxes) Cleaning and personal care products Their unique properties include: Resistance to oils and greases Thermal and chemical stability Anti-stick properties Challenges in Replacing Them Due to their unique properties, replacing PFAS in some applications is a significant challenge. Research and development of safe and effective alternatives is a current area of focus. Regulations EPA - National Primary Drinking Water Regulation for PFAS: focuses on protecting human...
