Estudio de las emisiones vehiculares en el Distrito Metropolitano de Quito: determinación de factores de emisión para estimar emisiones vehiculares en el DMQ, año base: 2018.

Abstract

Air pollution is becoming increasingly relevant in big metropolises. WHO establishes this as one of the greatest environmental threats to the health of the population, especially in developing countries. Furthermore, it causes nearly 7 million premature deaths each year, with children being the most vulnerable. One of the main sources of this pollution is produced by the vehicle fleet, therefore, in order to effectively manage air quality, it is important to make reports on mobile sources, which are known as emissions inventories and are made by the competent authority. For the preparation of these inventories it’s essential to obtain the emission factors and activity variables. In this way, the present curricular integration work was born, in order to determine the emission factors for exhaust, wear and evaporation of the pollutants CO, CO2, VOC, NOx, SO2, HC, PM10 and PM2.5, classified by type of vehicle and fuel corresponding to the year 2018 in the DMQ. This process was carried out using the EPA MOVES3 model. As a result, the aforementioned emission factors were obtained according to the age of the vehicle fleet, this allows establishing the difference in the emission factors of one type of vehicle with another, so that measures can be taken according to the most polluting vehicles that transit in the DMQ.
