ResumoTwenty-two volatile aromatic hydrocarbons were determined in the air of an automobile during commuting. Sampling was made on Tenax cartridges and laboratory determinations were carried out using thermal desorption combined with temperature-programmed capillary gas chromatography. Selected hydrocarbons representative of petrol exhaust were determined in the automobile and in an electric commuter train during eight parallel commuter trips. In the automobile, the concentrations of benzene were 35–70 μg/m3 and those of total aromatic hydrocarbons 200–400 μg/m3. The petrol exhaust levels were 5–10 times higher in the automobile than in the compartment of the commuter train.
