[Investigations of polycyclic aromatic hydrocarbons in cigarette smoke (author's transl)]

Polycyclic aromatic hydrobarbons (PAH), which are responsible for most of the carcinogenic activity of cigarette smoke were isolated from smoke condensate by distribution steps and chromatographic methods. The fractions containing substances in the range fluorence to chrysen were investigated by gaschromatography and mass-spectrometry. 150 substances were characterized. Unsubstituted PAH, alkyl-substituted PAH and O-heterocyclic compounds were identified.
