A total of 34volatile organic compounds (VOCs) were measured in the indoor of laboratories, offices and classrooms of the Chemical Engineering Department of Hacettepe University in Ankara in 2week-day passive sampling campaigns. The average concentrations ranged from 0.77 to 265g m(-3) at the different indoor sites, with the most abundant VOC found to be toluene (119.6g m(-3)), followed by styrene (21.24g m(-3)), 2-ethyltoluene (17.11g m(-3)), n-hexane (10.21g m(-3)) and benzene (9.42g m(-3)). According to the factor analysis, the evaporation of solvents used in the laboratories was found to be the dominant source.
