Indoor air composition inside the cabins of five new vehicles was examined. Air pollution was assessed on the basis of determination of volatile organic compound (VOC) concentrations, which were emitted from interior materials. Air samples were collected by active method onto a Carbograph 1TD. VOCs were analyzed using the TD-GC-FID/MS method. Presented results include concentrations of identified VOCs and three main group of compounds (aliphatic, aromatic, and cycloalkanes), as well as 18 target compounds and 10 main hydrocarbons, presented in vehicle interiors. It can be stated that interior air composition depended on materials used to finish the interior.
