Definition of cfcs in English English dictionary
- Chlorofluorocarbons (CFCs): A family of inert, nontoxic, and easily liquefied chemicals used in refrigeration, air conditioning, packaging, insulation, or as solvents and aerosol propellants. Because CFCs are not destroyed in the lower atmosphere they drift into the upper atmosphere where their chlorine components destroy ozone
- Chlorofluorocarbons
- Chlorofluorocarbons, chemicals which result in a depletion of the ozone layer in the upper atmosphere
- - Gaseous, synthetic substances composed of chlorine, fluorine and carbon They have been used as refrigerants, as aerosol propellants, as cleaning solvents, and in the manufacture of plastic foam As well as causing ozone depletion in the stratosphere, CFCs are greenhouse gases Their use is being phased out Some of their replacements are "ozone-friendly" but are potent greenhouse gases
- chemicals used in the manufacturing of aerosols, the cooling systems of fridges and fast food cartons These chemicals are harmful to the ozone laye
- These chemicals and some related chemicals have been used in great quantities in industry for refrigeration, air conditioning, and in consumer products CFCs and their relatives, when released into the air, rise into the stratosphere, a layer of the atmosphere high above the Earth In the stratosphere, CFCs and their relatives take part in chemical reactions which result in reduction of the stratospheric ozone layer, which protects the Earth's surface from harmful effects of radiation from the sun The 1990 Clean Air Act includes provisions for reducing releases (emissions) and eliminating production and use of these ozone-destroying chemicals
- chlorofluorocarbons – a group of ozone-depleting greenhouse gases
- A class of compounds, used as refrigerants and in other chemical processes, which deplete the ozone layer in the stratosphere
- Chlorofluorocarbons are a family of inert, nontoxic, and easily?liquefied chemicals used in automotive air conditioning, certain solvents and aerosol propellants Because CFCs can drift into the upper atmosphere (Stratosphere) where the chlorine is released, it can destroy the protective (UV radiation) ozone layer
- Any of a number of substances consisting of chlorine, fluorine, and carbon CFCs are used for refrigeration, foam packaging, solvents, and propellants They are proven to cause depletion of the atmosphere's ozone layer
- These chemicals and some related chemicals have been used in great quantities in industry, for refrigeration and air conditioning, and in consumer products CFCs and their relatives, when released into the air, rise into the stratosphere, a layer of the atmosphere high above the Earth In the stratosphere, CFCs and their relatives take part in chemical reactions which result in reduction of the stratospheric ozone layer, which protects the Earth's surface from harmful effects of radiation from the sun The 1990 Clean Air Act includes provisions for reducing releases (emissions) and eliminating production and use of these ozone-destroying chemicals
- are chlorine-containing chemicals which are use primarily as coolants in refrigerators, freezers, and air conditioners CFCs are also used as solvents, foam blowing agents and propellants, though the use of CFCs in aerosol cans in the U S was outlawed 15 years ago Though inert in the lower atmosphere, CFCs rise to stratosphere where their chlorine is freed and leads to ozone depletion Under the Montreal Protocol for the Protection of the Ozone Layer, the manufacture and use of CFCs is being phased out In the US and other industrialized countries, CFCs will no longer be manufactured after December 1995 Though the amount of CFCs released to the atmosphere is decreasing, the concentrations of chlorine in the stratosphere are still very high and due to the long atmospheric lifetimes of CFCs, ozone destruction will continue to increase for many years
- Chlorofluorocarbons, a group of semi-inert gases derived from the hydrocarbons methane and ethane, which liquefy easily For more information see sections 44,45
- Chlorofluorocarbons CFCs consist of a number of gases - best known under the trademark Freon Although they present no risk to human health or the environment while in contained use, if they escape to the atmosphere by leakage or incorrect disposal they can damage the stratospheric ozone layer as well as increase the greenhouse effect The ozone layer protects the Earth from harmful ultraviolet rays
- chlorofluorocarbons; family of chemicals used in several industrial applications that have been implicated in stratospheric ozone depletion
- stands for chlorofluorocarbons, which are in the class of pollutants called volatile organic compounds (VOCs); CFCs are also considered greenhouse gases (VOCs, greenhouse gases)
- Chlorofluorocarbons or chlorinated fluorocarbons are artificially produced chemicals that are partly responsible for depletion of the ozone layer CFCs have been used in refrigerants and a variety of other solvents since introduced in mid-1930
