Exposure data from the EXPOLIS study was used to compare the contributions of indoor andoutdoor sources to personal exposure to selected VOCs (TVOC, benzene, xylenes,ethylbenzene, nonane, decane, undecane, alpha-pinene and 3-carene) in Athens, Basel,Helsinki, Oxford and Prague for non-ETS-exposed individuals. Indoor sources were found tobe the largest contributors to personal exposure to TVOC, terpenes and alkanes. Theircontribution was also important for aromatics, including benzene in Basel and Prague.Workplaces contributed only marginally to the median population exposures. While personalexposures differ between the cities, the relative and absolute contributions of indoor sourcesdiffer much less.
