| Summary: | Exposure to contaminated environments has important health repercussions, especially for vulnerable groups such as children. The purpose of this study is to evaluate the concentrations of PM2.5 particulate matter in two educational institutions (EI) in both indoor and outdoor environments. During the period between June and October 2019, the concentrations were evaluated by means of low-cost PA-II-SD sensors from PurpleAir, which were validated and calibrated by parallel measurements with the Teledyne model T640X reference equipment. The PM2.5 average concentrations for the EIA were 14.46 and 17.26 µg/m3 and for the EIB of 19.18 and 18.95 µg/m3 in internal and external environments, respectively. Ventilation processes, classroom activity and vehicular traffic were the factors that most affected variations in concentrations. The Indoor/Outdoor relations at PM2.5 levels demonstrate that the EIA is less affected by external concentrations (I/O = 0.83), while the EIB has equal concentrations for both environments (I/O = 1.01). These variations are related to the location (being EIA in an urban background area and EIB an area close to the traffic influence) and the architectural conditions of the buildings evaluated. Likewise, significant differences were observed between working and non-working days and between the conditions of occupation of the classrooms. The results indicate the need to evaluate each EI individually, assuring a good air quality to children. |
