The levels of trichlorofluoromethane (F-11) and dichlorodifluoromethane (F-12) in coastal-water were investigated with ECD-GC using the head space technique. The sample gases of F-11 and F-12 were prepared by transferring F-11 and F-12 into the gas-phase in a flask and by concentrating the gases through a trapping tube. The average levels of F-11 and F-12 analyzed for 12 sampling points were 0.54±0.20 ppt and 0.33±0.19 ppt, respectively. The photolysis of the above coastal-water containing F-11 and F-12 was then conducted by a xenon lamp. The concentration of F-12 in the coastal-water did not decrease significantly, while that of F-11 increased slightly after 20 h of irradiation at the maximum.
