Monitoreo de la calidad del aire para los parámetros COx y CO2 en la zona sur de la parroquia de Calpi Cantón Riobamba

Abstract

The aim of this research was to identify the amount of carbon monoxide (COx) and carbon dioxide (CO2) emissions in the southern area of the Calpi parish, Riobamba country. Portable devices were integrated which were composed of a micro-SD adapter, an Arduino Uno board, and the following sensors: DHT11 for temperature and humidity monitoring, time sensor ZS-042, carbon monoxide sensor MQ7, and carbon dioxide sensor MQ135. These portable devices were placed at ten monitoring points. Three data were collected per hour, 24 hours a day for a period of thirty days, maintenances were executed every eight days. Once the information was obtained, data calibration calculations, unit conversion and the corresponding statistical analysis were performed. The results indicated that the highest emission points were: P7 with 997.97 ug/m3 of COx and P2 with 24.73 ppm of CO2. Such values are within the parameters of the Ministerial Agreement 097-A of 2015 and the guide of the National Security Institute and Health at Work of 2019 (INSST) respectively. It is recommended to carry out monitoring in different periods with the use of portable devices due to its easy transportation, as well as the implementation of a better database.
