Polyfluorinated Substances (PFAS) are man-made chemicals commonly found in products like non-stick cookware, waterproof textiles, and firefighting foams. These substances pose significant health and environmental risks. Exposure to PFAS has been associated with an increased risk of cancer, thyroid disease, immune system dysfunction, and developmental issues. Moreover, PFAS can persist in the environment for extended periods, potentially accumulating in ecosystems and impacting wildlife. You can learn more about PFAS and their effects here. As ambient air testing professionals, it is essential to be aware of these substances and ensure that we keep this topic on our radars as new legislation continues to be discussed.
