Definition of chlorofluorocarbon in US English:



  • fuller form of CFC
    • ‘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.’
    • ‘The Caltech scientists suggest certain scenarios in which the impact could be similar to what chlorofluorocarbons inflicted on the ozone layer.’
    • ‘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 hole isn't shrinking yet, but our use of aerosols and other chlorofluorocarbons is.’
    • ‘Once the spring returns, this chlorine, much of it originating from man-made pollutants like chlorofluorocarbons, disrupts the ozone layer.’
    • ‘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).’
    • ‘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.’
    • ‘The release of chlorofluorocarbons has led to the chemical reaction breaking down the ozone layer.’
    • ‘Ozone loss in Earth's stratosphere is caused primarily by chemical reactions with chlorine from human-produced compounds like chlorofluorocarbons.’
    • ‘The concentration of CFCs in the atmosphere has increased almost exponentially since the 1930s but different chlorofluorocarbons have been released at known different rates.’
    • ‘Stratospheric ozone over polar regions is subjected to enhanced seasonal depletion caused by emission of chlorofluorocarbons and other halogenated compounds.’
    • ‘And today we will add 2,700 tons of chlorofluorocarbons to the atmosphere and 15 million tons of carbon.’
    • ‘The EU directive concerns the disposal of chlorofluorocarbons, CFCs, which damage the ozone layer if released into the atmosphere.’
    • ‘The protocol restricts the manufacture and use of human-made, ozone-depleting compounds, such as chlorofluorocarbons and halons.’
    • ‘If they contain only fluorine, chlorine and carbon they are called chlorofluorocarbons, or CFCs for short.’
    • ‘During the 1980s evidence emerged linking the release of chlorofluorocarbons, halons, and other chlorine-based substances with the gradual destruction of the ozone layer.’
    • ‘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.’
    • ‘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.’
    • ‘Up until the 1980s, a lot of liquefied-gas aerosol cans used chlorofluorocarbons as a propellant.’
    • ‘Refrigerator models made before 1994 may be insulated with chlorofluorocarbons, which also damage the earth's atmosphere.’


1940s: from chloro- + fluoro- + carbon.
