Comportamiento y análisis del Dióxido de Azufre (SO2) y Dióxido de Nitrógeno (NO2) en Bogotá D.C. para el periodo 2019 – 2020 y su estado dentro de los sistemas de vigilancia de calidad del aire para Colombia y Latinoamérica

Abstract

NO2 and SO2 are part of the five (5) criteria pollutants established by the WHO as a result of the effects they generate on health immediately after inhalation. Due to the sources of anthropogenic generation that these compounds present, there has been a significant increase in their emissions worldwide, putting the health of the inhabitants of the main cities of the world at risk. (University of the Andes, University College London, 2013). Therefore, these compounds must be monitored and controlled at all times by the corresponding environmental authorities. In Bogotá, the Air Quality Monitoring Network (RMCAB) has 16 stations that make up the Bogotá Air Quality Surveillance System, which monitors these pollutants and generates reports with concentrations on an hourly basis. (District Environment Secretariat, 2021) With the available information, it is possible to establish the concentration of pollutant in a certain place at a certain time of day, however, the concern arises about how these pollutants are behaving in the city, since with the analysis of this behavior it can be made known. , for example: where are the highest concentrations occurring during the day and at night, which days of the week have the highest concentration or at what time of the day is the highest concentration evident. But in addition to this, it is necessary to know the status of the monitoring of these pollutants within the SVCA of Bogotá and Colombia. As in Colombia, different Latin American countries have air pollutant monitoring stations belonging to the Air Quality Surveillance Systems, such as Venezuela, Brazil, Argentina, Mexico, Ecuador, Peru, Guatemala, among others. (The World Air Quality Project, 2021). Among their SVCA, the concentrations of NO2 and SO2 are measured, in some or all of the stations that they have available. It is really necessary to know how good the monitoring of these two pollutants is in Colombia compared to the monitoring that is done in other Latin American countries to establish what conditions the country's SVCA is in and what improvements are required to offer a better decision tool. national authorities regarding air quality.
