dc.description.abstract | Despite the risk of transmission of SARS-CoV-2, Spanish educational centers were reopened after six months of
lockdown. Ventilation was mostly adopted as a preventive measure to reduce the transmission risk of the virus.
However, it could also affect indoor air quality (IAQ). Therefore, here we evaluate the ventilation conditions,
COVID-19 risk, and IAQ in secondary school and university classrooms in Toledo (central Spain) from November
2020 to June 2021. Ventilation was examined by monitoring outdoor and indoor CO2 levels. CO2, occupancy and
hygrothermal parameters, allowed estimating the relative transmission risk of SARS-CoV-2 (Alpha and Omicron
BA.1), Hr, under different scenarios, using the web app COVID Riskairborne. Additionally, the effect of ventilation
on IAQ was evaluated by measuring indoor/outdoor (I/O) concentration ratios of O3, NO2, and suspended
particulate matter (PM). University classrooms, particularly the mechanically ventilated one, presented better
ventilation conditions than the secondary school classrooms, as well as better thermal comfort conditions. The
estimated Hr for COVID-19 ranged from intermediate (with surgical masks) to high (no masks, teacher infected).
IAQ was generally good in all classrooms, particularly at the university ones, with I/O below unity, implying an
outdoor origin of gaseous pollutants, while the source of PM was heterogeneous. Consequently, controlled
mechanical ventilation systems are essential in educational spaces, as well as wearing well-fitting FFP2–N95
masks indoors is also highly recommended to minimize the transmission risk of COVID-19 and other airborne
infectious diseases. | es |
