Implementación de una red de monitoreo atmosférico de material particulado 2.5, en siete colegios del sector de Chillogallo del Distrito Metropolitano de Quito con sensores de bajo costo en el segundo semestre del 2022

Abstract

The present research work was carried out to evaluate the air quality in seven educational institutions belonging to the Chillogallo sector in the Metropolitan District of Quito based on exposure to particulate matter 2. 5, through atmospheric monitoring using low-cost sensors and real-time monitoring through the virtual platform Aire Ciudadano to determine the level of efficiency of the data obtained using sensors as a more accessible and economical alternative so as to establish an interest, awareness and prevention of air pollution by the student community and the population in general. For which, the monitoring points of the area were identified based on the presence of educational institutions most exposed to the pollutant, considering the sources of particulate matter, the composition of the particles and, most importantly, the negative impact on human health due to factors such as vehicular pollution. For the development of the research, we obtained the mean and maximum peak concentrations of the pollutant for its evaluation according to the permissible limits of the World Health Organization (WHO) and the Ecuadorian Air Quality Standard, as well as meteorological variables for each month at each monitoring point for the calculation of the Air Quality Index (AQI).
