Indice de calidad del aire en cinco instituciones educativas del Centro Histórico de la Ciudad de Cuenca, mediante estaciones móviles, tendiente a verificar con la normativa ambiental vigente

Abstract

This study was carried out in five educational institutions located in the historic center of Cuenca, with the purpose of determining the air quality index by analyzing the concentration of pollutants. The pollutants analyzed were Carbon Monoxide (CO), Carbon Dioxide (CO₂), Nitrogen Dioxide (NO₂), Hydrogen Sulfide (H₂S), Ozone (O₃), Fine Particulate Matter (PM2.5), Ultraviolet Radiation (UV), and Atmospheric Pressure (hPa). The study responds to the need to identify air pollution levels in institutions to compare whether they comply with the permissible limits established by international standards. The research was carried out during defined periods during October, November, and December 2024 using mobile measuring stations. The results showed that most of the parameters analyzed are within permissible ranges. However, high concentrations of CO₂ were identified indoors, as well as critical levels of PM2.5 outdoors. These conditions influence air quality and human well-being. It is concluded that the values found do not exceed permissible air quality ranges, but in some cases, such as that of CO2, measures are necessary. Periodic monitoring of environmental parameters is recommended to ensure optimal well-being conditions in educational institutions.
