chlorofluorocarbons

A range of compounds, composed of chlorine, fluorine, carbon and hydrogen, used as aerosol propellants and refrigerants. CFCs have become discredited because of their effect on the ozone layer.

chlorofluorocarbons (CFCs)

greenhouse gases. Compounds which contain chlorine, fluorine and carbon often together with hydrogen, used for the manufacture of solvents, aerosols, refrigerants and plastic foams; they cause ozone depletion in the stratosphere and absorb long-wave radiation.
