Elaboración de un inventario de emisiones atmosféricas de fuentes moviles del Canton Ambato del año 2019, mediante la aplicación del modelo ive

Abstract

The objective of this study was to carry out an inventory of atmospheric emissions in Ambato in 2019 based on the IVE software model. This study estimated primary pollutants, particulate matter, and greenhouse gases. For this, it was necessary to collect information from pertinent entities regarding traffic in the city, and by the method of direct counting in situ to establish the vehicle fleet of the city in 4 pertinent points: (Yahuira, April 13, Francisco Flor y el Paso Lateral), whose percentage composition is 8442 vehicles per day. In addition to collecting information through 200 surveys on automotive technology, cold stops, type of fuel used, and other parameters that allow calculating emission factors. The vehicular activity was measured with four vehicles corresponding to each vehicle category (motorcycles, taxis, buses and individuals), each equipped with GPS. The results were entered into the IVE model to calculate the pollutants (CO2, CO, NOx, SOx, PM and VOCs). The emission of a total of 10896.31 kilograms per day was obtained, where the highest emission is CO2 with 9924.16 kg/day, followed by CO with 762.01 kg, VOC with 74.47 kg, NOx 94.69 kg, SOX with lower emission of 1.20 kg/day, in addition to Particulate Material with emission of 39.68 kg/day. The rush hour in Ambato is established at 7 AM, 12 PM and 5 PM. Based on the results, it is recommended to be complemented with other emission sources such as vegetation, electric generators and the industrial park; the dispersion of pollutants is established, and transit entities have become more rigorous with vehicle inspections and achieve reduced the use of obsolete technologies.
