What are chlorofluorocarbons (CFCs)? Chlorofluorocarbons (CFCs) are a group of manufactured chemical compounds that contain chlorine, fluorine, and carbon. This group includes CFC-11, CFC-12, CFC-113, CFC-114, CFC-115, and many forms of Freon. They are colorless, odorless, nontoxic, nonflammable, and stable when emitted. When they are emitted and reach the stratosphere, they break apart and release chlorine atoms, which destroy the earthâs ozone layer. CFCs can last for more than 100 years in the stratosphere. Because they destroy the ozone layer, CFCs have been banned from production in the United States since December 31, 1995.
Hexachlorobutadiene is not found naturally in the environment, and is primarily released into the environment from its disposal following industrial uses. When emitted into the air, hexachlorobutadiene has a half life of 60 days, in which it may be broken down into other chemicals.
