The automobile cabin is an important part of the living environment. Particulate matter collected in automobile compartments may contain elevated levels of semi volatile compounds (SVOCs), such as PBDE (polybrominated diphenyl ethers). Therefore, the exposure in transport vehicles is of growing importance. Dust samples were collected from private cars in the city of Lublin, Poland. Lower brominated congeners were found in all the samples, with BDE-99 being the most abundant congener. Higher concentrations of particular congeners in cars equipped with AC were found, which might be related mainly to indoor sources of PBDE. Higher odometer readings might show the impact of outdoor sources, although some transformation of congeners during usage and sun light influence might be a reason. The highest concentration of BDE-138 were found in the automobiles produced outside the EU, although the highest concentrations of BDE-99 were observed in cars manufactured in the EU.
