【 摘 要 】

Simultaneous measurementsof outdoor and indoor pollution were performed at three schools in Lisbon. Volatileorganic compounds (VOCs), formaldehyde and NO2 were passively monitoredover a two-week period. Bacterial and fungal colony-forming units and comfortparameters were also monitored at classrooms and playgrounds. The highest indoorlevels of CO2 (2666 μg/m3),NO2 (40.3 μg/m3),VOCs (10.3 μg/m3),formaldehyde (1.03 μg/m3)and bioaerosols (1634 CFU/m3), and some indoor/outdoor ratios greaterthan unity, suggest that indoor sources and building conditions might have negativeeffects on air indoors. Increasing ventilation rates and use of low-emissionmaterials would contribute towards improving indoor air quality.
