Abstract
La formación de Ozono a partir de COV y NOx es un tema que requiere mucha atención en nuestro país, ya que el ozono troposférico presenta un gran riesgo para el medio ambiente, la salud de las personas, animales y vegetales, pero al ser un tema poco conocido es que en Chile no se ha desarrollado ningún modelo predictivo oficial para el ozono. Por lo tanto, este trabajo se realiza en el marco del proyecto interno multidisciplinario realizado por la USM titulado: “Desarrollo e implementación de un modelo fotoquímico predictivo de formación de ozono troposférico en Santiago de Chile mediante modelación inversa”. El objetivo general de este trabajo es determinar la desagregación química, espacial y temporal de emisiones vehiculares precursoras de ozono troposférico. Para lograr este objetivo se recurrió a la base de datos de COPERT para obtener información sobre la especiación de COVs y NOx según distintas categorías vehiculares y tecnologías; se obtuvieron los perfiles vehiculares para distintos sectores de Santiago, así como la distribución de los vehículos por cada sector de estudio; se definieron las rutas, y finalmente, mediante el software QGIS se modeló la información para obtener la distribución tanto temporal como espacial.
The formation of Ozone from VOCs and NOx is a topic that requires a lot of attention in our country, that tropospheric ozone presents a great risk to the environment, the health of people, animals and plants, even with that in mind no official predictive model for ozone has been developed. Therefore, this work is carried out within the framework of the multidisciplinary internal project carried out by the USM entitled: "Development and implementation of a predictive photochemical model of tropospheric ozone formation in Santiago, Chile through inverse modeling". The general objective of this work is to determine the chemical, spatial and temporal disaggregation of vehicle emissions precursors of tropospheric ozone. To achieve this objective, the COPERT database is used to obtain information on the specification of VOCs and NOx according to the different categories of vehicles and technologies; The profiles of vehicles for different sectors of Santiago were obtained, as well as the distribution of the vehicles for each sector of study; The routes were defined, and finally, using the QGIS software, the information was modeled to obtain both temporal and spatial distribution.
