chlorofluorocarbon

definition
noun
Their research teams subsequently carried out experiments in the atmosphere that supported their hypothesis, leading to a worldwide effort to reduce the release of chlorofluorocarbons into the atmosphere.
any of a class of compounds of carbon, hydrogen, chlorine, and fluorine, typically gases used in refrigerants and aerosol propellants. They are harmful to the ozone layer in the earth's atmosphere owing to the release of chlorine atoms upon exposure to ultraviolet radiation.
example
Up until the 1980s, a lot of liquefied-gas aerosol cans used 'chlorofluorocarbons' as a propellant.
The concentration of CFCs in the atmosphere has increased almost exponentially since the 1930s but different 'chlorofluorocarbons' have been released at known different rates.
An example of this process is the formation of free radicals from 'chlorofluorocarbons' in the upper atmosphere (leading to the depletion of the ozone layer).
Refrigerator models made before 1994 may be insulated with 'chlorofluorocarbons' , which also damage the earth's atmosphere.
Since excess 'chlorofluorocarbons' have been released into the atmosphere, the protecting stratospheric ozone layer has decreased and humans and animals are exposed to increased ultraviolet radiation.
If they contain only fluorine, chlorine and carbon they are called 'chlorofluorocarbons' , or CFCs for short.
The Caltech scientists suggest certain scenarios in which the impact could be similar to what 'chlorofluorocarbons' inflicted on the ozone layer.
The protocol restricts the manufacture and use of human-made, ozone-depleting compounds, such as 'chlorofluorocarbons' and halons.
And today we will add 2,700 tons of 'chlorofluorocarbons' to the atmosphere and 15 million tons of carbon.
In the last half of the twentieth century, the manufacture of 'chlorofluorocarbons' for use as propellants in aerosol sprays and refrigerants has resulted in a slow mixing of these compounds with the stratosphere.
The hole isn't shrinking yet, but our use of aerosols and other 'chlorofluorocarbons' is.
The EU directive concerns the disposal of 'chlorofluorocarbons' , CFCs, which damage the ozone layer if released into the atmosphere.
Once the spring returns, this chlorine, much of it originating from man-made pollutants like 'chlorofluorocarbons' , disrupts the ozone layer.
Their research teams subsequently carried out experiments in the atmosphere that supported their hypothesis, leading to a worldwide effort to reduce the release of 'chlorofluorocarbons' into the atmosphere.
Stratospheric ozone over polar regions is subjected to enhanced seasonal depletion caused by emission of 'chlorofluorocarbons' and other halogenated compounds.
Ozone loss in Earth's stratosphere is caused primarily by chemical reactions with chlorine from human-produced compounds like 'chlorofluorocarbons' .
A brief reference to the destruction of the ozone layer by 'chlorofluorocarbons' , which has greatly enhanced the risk of skin cancer through increased ultraviolet radiation, appears in the summary of that section.
When certain gases - carbon dioxide, water vapor, methane, 'chlorofluorocarbons' , and others - are released into the atmosphere, they naturally act like the glass panes of a greenhouse.
The release of 'chlorofluorocarbons' has led to the chemical reaction breaking down the ozone layer.
During the 1980s evidence emerged linking the release of 'chlorofluorocarbons' , halons, and other chlorine-based substances with the gradual destruction of the ozone layer.
