WebChlorofluorcarbons (CFCs) are a group of chemical substances that contain one, two or three carbon atoms and at least one atom each of chlorine and fluorine. CFCs were first developed in the 1920s to replace sulphur dioxide as a coolant gas. In the 1930s they began to replace ammonia for cooling uses. WebCFCs or chlorofluorocarbons are compounds that are essentially inert in the troposphere. The main compounds used as tracers in natural systems are CFC 11 (CCl 3 F), CFC 12 (CCl 2 F 2) and CFC 113 CCl 2 F-CClF 2 ). All compounds have no known natural sources.
