Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals widely used in industry and consumer products since the 1940s. Known for their resistance to heat, water, and oil, PFAS are found in items like food packaging, nonstick cookware, firefighting foams, water- and stain-resistant textiles, and personal care products such as shampoos, dental floss, and makeup. However, their production and use have led to environmental contamination.
