The decrease of the amount of trichlorofluoromethane (F-11) and dichlorodifluoromethane (F-12) by irradiation was studied by gas chromatography (GC) and GC-mass spectrometry (MS). When the sea-water containing both F-11 (14.7 ppm) and F-12 (73.9 ppm) was irradiated with a xenon lamp, 48.8% and 55.1% of them were lost in 25 h, respectively. The benzene extract of the irradiated sea-water contained at least 3 products of which amounts increased with the time of irradiation. GC-MS analysis indicated that bromochlorodifluoromethane (CBrClF_2) and 1,3-butadiyne (CH≡C-C≡CH) were 2 of the 3 products formed by the irradiation.
