What is PFAS? Per- and polyfluoroalkyl substances, often referred to as "forever chemicals," are a group of man-made chemicals characterized by their durability and persistence in the environment. These substances are resistant to heat, water, and grease, making them highly useful in a variety of consumer products. PFAS are commonly found in nonstick cookware, water-repellent fabrics, food packaging, and even some cosmetic and personal care products. However, their widespread use and environmental persistence have led to significant concerns. PFAS can seep into soil and water supplies, posing potential health risks to humans and wildlife. Exposure to these chemicals has been associated with a range of health issues, including immune system suppression, reproductive problems, and an increased risk of certain cancers. As awareness grows, there are increasing calls for regulations and actions to limit PFAS exposure and mitigate their impact on both human health and the environment.
