and fluorine, once used widely as aerosol propellants and refrigerants. Volatile chlorofluorocarbons are believed to cause depletion of the atmospheric ozone layer. Chlorofluorocarbons, also known as CFCs, consist of chemical compounds made up of chlorine, fluorine and carbon. CFCs are particularly harmful when released into the atmosphere because of their destructive reaction with O-zone particles, which provide the Earth with a.
One estimate is that every chlorine atom in the stratosphere destroysozone atoms before the chlorine is converted to an unreactive form. Chlorofluorocarbons trap more heat in the atmosphere per molecule than other substances.
The global warming potential of CFC is times that of CO 2. CHLOROFLUOROCARBONS Chlorofluorocarbons (CFCs) are a class of chemicals that contain only atoms of carbon, chlorine, and fluorine. As a group, they are unreactive, stable, and poorly soluble in water.
Commercially, the most important CFCs were derivatives of methane and ethane. The world production of CFCs reachedtonnes in (Crutzen ), after growing at an average rate of about 9 per cent in the s (Molina and Rowland ). The total production of CFCs and halons amounted to 1, tonnes inbefore falling to.
