Characterization of particulate matters and total VOC

Indoor TVOC in this study ranged from 230 to 7000 μg/m 3 (∼100–3044 ppb) with a geometric mean of 510 μg/m 3 (∼222 ppb). The highest TVOC was observed in those offices possessing wet-process photocopier machines. Pegas et al. evaluated seasonal indoor air quality of 12 primary schools with blackboard and chalk set-up in Lisbon, Portugal.
