Abstract (EN):
Indoor air pollution mitigation measures are highly important due to the associated
health impacts, especially on children, a risk group that spends significant time indoors. Thus,
the main goal of the work here reported was the evaluation of mitigation measures implemented
in nursery and primary schools to improve air quality. Continuous measurements of CO2, CO,
NO2, O3, CH2O, total volatile organic compounds (VOC), PM1, PM2.5, PM10, Total Suspended
Particles (TSP) and radon, as well as temperature and relative humidity were performed in two
campaigns, before and after the implementation of low-cost mitigation measures. Evaluation of those
mitigation measures was performed through the comparison of the concentrations measured in both
campaigns. Exceedances to the values set by the national legislation and World Health Organization
(WHO) were found for PM2.5, PM10, CO2 and CH2O during both indoor air quality campaigns.
Temperature and relative humidity values were also above the ranges recommended by American
Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). In general, pollutant
concentrations measured after the implementation of low-cost mitigation measures were significantly
lower, mainly for CO2. However, mitigation measures were not always sufficient to decrease the
pollutants’ concentrations till values considered safe to protect human health.
