Tests have been carried out to determine whether chlorofluoromethanes in air are appreciably decomposed on passing through lighted cigarettes. Fourier transform infrared spectroscopy was used to see if CCl3F or CHClF2 might yield COCl2, COClF, or COF2. None of these decomposition products was seen, even though measurement sensitivity was high enough to reveal a conversion of one one-thousandth of the starting material. It is concluded that chlorofluoromethane pollutants in room air do not pose any greater health hazard to smokers than to non-smokers.
