PFAS, or poly- and perfluoroalkyl substances, encompass approximately 5,000 non-degradable chemicals widely used since the 1950s. Commonly found in non-stick cookware, waterproof clothing, packaging, and firefighting foam, PFAS are generally toxic and can accumulate in tissue, affecting the immune system and potentially leading to cancer with long-term exposure. Recent findings have detected PFAS in hobby eggs, raising concerns about their environmental impact.
