CFCs (fully halogenated hydrocarbon containing chorine and fluorine atoms in their molecule): these chemicals were for the first time synthesized in twenties of the last century. They found application because of their chemical stability and other useful characteristics: they are non-toxic, inflammable, they do not affect living organisms and are not carcinogen.
The most common ozone depleting substances are chlorofluorocarbons (CFCs) used for refrigeration, air-conditioning, blowing foams, solvents, sterilants and aerosol propellants. When released into the atmosphere these CFCs are broken apart by solar radiation, thus releasing a chlorine atom which reacts with the ozone molecule.
