PFAS is a group of chemicals collectively known as per- and polyfluoroalkyl substances. Due to their excellent properties, including water repellency, heat resistance, and chemical resistance, they are used across a wide range of industrial sectors. Representative applications include food packaging materials, stain-resistant clothing, firefighting agents, and electronic components and semiconductor manufacturing processes. However, their stable chemical structure makes them resistant to degradation and prone to accumulation in the environment, raising concerns about adverse effects on humans and ecosystems. Internationally, certain PFAS, such as PFOS (perfluorooctane sulfonic acid) and PFOA (perfluorooctanoic acid), are subject to regulation, necessitating measures to address environmental pollution and health risks.
