Per- and Polyfluoroalkyl Substances (PFAS)

Per- and Polyfluoroalkyl Substances (PFAS) are a large group of human-made chemicals used in many products like non-stick cookware, water-repellent clothing, and fire-fighting foam. They are resistant to heat, water, and oil, which makes them useful but also persistent in the environment and human body. PFAS do not break down easily, leading to long-term contamination of water, soil, and living organisms. Exposure to certain PFAS has been linked to health issues such as cancer, immune system effects, and hormone disruption. Efforts are ongoing to regulate, remove, and find safer alternatives to these chemicals.
