Homonym: CFC (Refrigerant)
CFC stands for chlorofluorocarbon, a group of man-made compounds used primarily as refrigerants, propellants, and solvents. They are composed of chlorine, fluorine, and carbon atoms. CFCs were widely used in products like air conditioners and aerosol sprays due to their stability and effectiveness. However, they are harmful to the environment, particularly the ozone layer.
The release of CFCs into the atmosphere contributes to ozone depletion, which allows harmful ultraviolet (UV) radiation to reach the Earth's surface. This led to international agreements, such as the Montreal Protocol, aimed at phasing out the production and use of CFCs to protect the ozone layer and reduce environmental damage.
