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