Perfluorocarbon (PFC) is a group of human-made compounds that contain carbon and fluorine atoms. They are known for their stability and resistance to chemical reactions, making them useful in various industrial applications, including electronics and refrigeration. PFCs are also used in medical imaging and as a potential treatment for certain lung conditions due to their ability to carry oxygen. These compounds are significant in discussions about climate change because they are potent greenhouse gases. Although they are present in the atmosphere in small amounts, their long atmospheric lifetimes can contribute to global warming. Efforts are ongoing to reduce PFC emissions and find alternatives to their use in industries.
