1.
CFCs; chlorofluorocarbons; freon gas
A class of synthetic gases formerly used as refrigerants and in aerosol sprays, now phased out because they damage the ozone layer. The Japanese term covers CFCs and related halogenated coolants in general usage.
フロン is the Japanese short form for fluorocarbons/freon; フロンガス is the gas form. The Montreal Protocol (1987) led to a gradual phase-out, with replacement refrigerants (代替フロン) now in common use.
