Auto Air Conditioners and the Ozone Layer: Background | Ozone Depletion - Regulatory Programs | U.S. EPA
(UV-B) radiation. Once there, CFCs break apart - a process that releases chlorine, which then attacks ozone. A single chlorine atom can destroy more than 100 thousand ozone molecules. The ozone layer is ... HFC-134a. This refrigerant does not deplete the ozone layer because it does not contain chlorine. By the end of 1994, virtually all new cars, trucks and vans were equipped with ...

Reports to the Nation on Our Changing Planet: Our Ozone Shield
Rowland and Molina hypothesized that the chlorine buildup from CFCs would spell severe trouble for the ozone layer. According to their predictions, each chlorine atom could destroy 100,000 ozone molecules ... climes. these icy particles have a critical effect on the chlorine and bromine pollution floating in the stratosphere. Normally, the chlorine and bromine are largely locked into "safe" compounds ...

Why the banning of Chlorofluorocarbons is paranoia.
CFCs, releasing their ozone-destroying chlorine, as well as oxygen, creating ozone, there is a 'competition' between the two processes ... the National Oceanic and Atmospheric Administration show 60,000 ozone molecules are created for every chlorine atom released from a CFC molecule. With this probability, how can the equilibrium density of ...

Ozone Depletion | Chlorofluorcarbons | CFCs | Stratospheric Ozone
When UV radiation hits a CFC molecule it causes one chlorine atom to break away. The chlorine atom then hits an ozone molecule consisting of three oxygen atoms and takes one ... the molecule of chlorine monoxide, the two oxygen atoms join and form an oxygen molecule. When this happens, the chlorine atom is free and can continue to destroy ozone. Naturally occurring chlorine has the ...
