Perfluorinated chemicals (PFCs) are a group of synthetic compounds used in various industrial and consumer products. They are known for their water- and grease-resistant properties, making them popular in items like non-stick cookware, water-repellent fabrics, and food packaging. PFCs are persistent in the environment and can accumulate in living organisms, raising concerns about their potential health effects. Studies have linked exposure to PFCs with various health issues, including immune system effects and developmental problems. Regulatory agencies are working to assess and manage the risks associated with these chemicals.
