Comparación de mediciones de PM 2,5 y calidad de aire en la Universidad Politécnica Salesiana mediante datos obtenidos por equipo de alto volumen, un sensor de bajo costo y la Estación de Monitoreo Atmosférico de Guamaní

Abstract

In the present investigation, a comparison of data obtained by three low-cost sensor monitoring methods, High-Volume and Guamaní Monitoring Station at the Universidad Politecnica Salesiana, Sede Quito, Campues Sur, was carried out, the monitoring points were strategically chosen due to the high vehicular and pedestrian concentration. The study was carried out in a period of three months from April to June taking data during 7 hours 5 days a week.by means of this study we obtained data such as the average, midpoint, maximum point, standard deviation to later make the necessary comparisons.after obtaining the necessary amount of data to make the necessary comparison between the three monitoring methods and obtain the results studied. It was possible to conclude the concentration of particulate matter PM 2,5 present in the Salesian Polytechnic University and also to know which of the three methods is better in its use for future studies.likewise we could see the changes in concentration that are evident within the monitoring points either by physical, chemical or environmental causes.
