Abstract

A very sensitive mass-spectrometry method has been developed for the analysis of aromatic amines in tobacco smoke and in indoor air. Cigarettes were smoked with a smoking machine; the amines from the smoke were trapped in a 5% HCl water solution containing internal standards and detected by gas chromatography/mass spectrometry in the selected-ion-monitoring (SIM) mode. The amines measured were the following: aniline, 2-toluidine, 3-toluidine, 4-toluidine, 2-ethylaniline, 3-ethylaniline, 4-ethylaniline, 2,3-dimethylaniline, 2,4-dimethylaniline, 2,5-dimethylaniline, 2,6-dimethylaniline, 1-naphthylamine, 2-naphthylamine, 2-methyl-1-naphthylamine, 2-aminobiphenyl, 3-aminobiphenyl and 4-aminobiphenyl. We analyzed nine brands of cigarettes sold commercially in Italy (Gauloise, Nazionali, Marlboro, Camel, MS, MS mild and MS lights), with and without filter. Main-stream smoke contained a lower amount of aromatic amines than side-stream smoke: the total level of these amines in main-stream smoke ranged from 200 to 1300 ng/cigarette, whereas the level of aromatic amines in side-stream smoke varied from 20,000 to 30,000 ng/cigarette. The smoke of black-tobacco cigarettes had higher levels of aromatic amines compared to light-tobacco cigarettes and the filters significantly reduced aromatic amines in main-stream smoke. We also determined the levels of aromatic amines in ambient air, offices and houses. Some aromatic amines (aniline and toluidine) were detected in ambient air, as well as in rooms of non-smokers. Most measurements showed a considerable contamination of aromatic amines derived from side-stream smoke, which was detected also in parts of the buildings in which smoking was not allowed.
