PFAS (per- and polyfluoroalkyl substances, AKA "forever chemicals") are a group of human-made chemicals widely used for their water- and stain-resistant properties in products like non-stick cookware, water-resistant clothing, and food packaging.
Known as "forever chemicals" because they break down very slowly, PFAS can persist in the environment and the human body, leading to potential health risks including liver damage, immune system effects, and an increased risk of certain cancers.
PFAS are important because they're found in many everyday products and don't break down easily. Their long-term presence in the environment and our bodies can lead to health concerns, making them a growing focus for safety and regulation.
