TL;DR: In this article, the authors measured the levels and the element composition of PM2.5 in three primary schools placed in Lisbon, in order to assess the children exposure to these pollutants and investigate the sources of high aerosols concentrations in classrooms.

TL;DR: The aromatic compounds benzene, toluene, ethylbenzene and xylenes, followed by ethers, alcohols and terpenes, were usually the most abundant classes of VOCs, and indoor total VOC concentrations were markedly higher than those observed outdoors.

TL;DR: In this article, simultaneous measurements of outdoor and indoor pollution were performed at three schools in Lisbon, and the highest indoor levels of CO2, NO2, VOCs, formaldehyde and bioaerosols were measured over a two-week period.

TL;DR: It has been observed that higher indoor VOC concentrations occurred more often in the colder months, while carbonyl concentrations were higher in the warm months, thus showing the importance of indoor sources and building conditions in indoor air quality.

TL;DR: In this article, the authors investigated pollutant concentrations inside and outside school buildings at different locations (city centre and suburban) in Aveiro, Portugal, between April and June 2010, and evaluated simultaneously comfort parameters (temperature, relative humidity, CO2 and CO) and indoor and outdoor concentrations of VOCs, NO2, PM10 and bioaerosols.
