English title:	Air quality assessment using a photochemical model: case study
Spanish title:	Evaluaci�n de la calidad del aire usando un modelo fotoqu�mico: estudio de caso
English abstract:	Several modeling and simulation studies on the formation of secondary pollutants in the atmosphere have been carried out in recent years to investigate dispersion patterns, predict behavioral emissions, estimate potential risks to human health, develop environmental policies and assess their impact on the quality of air in the directly affected area. A photochemical mechanism for tropospheric chemistry is a mathematical description of photochemical processes of the lower atmosphere through a series of chemical reactions involving primary and secondary pollutants. Species considered in a photochemical mechanism are categorized as inorganic compounds and organic compounds, mainly volatile organic compounds. Secondary air pollutants, such as ozone, are formed in the troposphere by chemical reactions between primary pollutants during the day, in particular, nitrogen oxides, carbon monoxide, and VOCs that are emitted directly into the atmosphere. These primary pollutants are mainly caused by anthropogenic activities. For a good prediction of the formation of secondary pollutants, it is necessary to describe in detail the emission of precursor compounds, their transport, dispersion, mixing, and chemical reactions. In this work, an Kinetic Model and Ozone Isopleth Package for Research trajectory model from the United States Environmental Protection Agency and the Statewide Air Pollution Research Center model, which includes thermal and photochemical reactions that serve to reproduce the studied scenarios and estimate the reactivity. The model was applied to experimental results obtained at Santos Dumont Airport, located in the city of Rio de Janeiro, Brazil.
Spanish abstract:	En los �ltimos a�os se han llevado a cabo varios estudios de modelado y simulaci�n sobre la formaci�n de contaminantes secundarios en la atm�sfera para investigar patrones de dispersi�n, predecir emisiones conductuales, estimar riesgos potenciales para la salud humana, desarrollar pol�ticas ambientales y evaluar su impacto en la calidad del aire de la zona directamente afectada. Un mecanismo fotoqu�mico para la qu�mica troposf�rica es una descripci�n matem�tica de los procesos fotoqu�micos de la atm�sfera inferior a trav�s de una serie de reacciones qu�micas que involucran contaminantes primarios y secundarios. Las especies consideradas en un mecanismo fotoqu�mico se clasifican en compuestos inorg�nicos y compuestos org�nicos, principalmente compuestos org�nicos vol�tiles. Los contaminantes atmosf�ricos secundarios, como el ozono, se forman en la troposfera por reacciones qu�micas entre los contaminantes primarios durante el d�a, en particular, los �xidos de nitr�geno, el mon�xido de carbono y los compuestos org�nicos vol�tiles que se emiten. directamente a la atm�sfera. Estos contaminantes primarios son causados principalmente por actividades antropog�nicas. Para una buena predicci�n de la formaci�n de contaminantes secundarios, es necesario describir en detalle la emisi�n de compuestos precursores, su transporte, dispersi�n, mezcla y reacciones qu�micas. En este trabajo se utiliza un modelo de trayectoria Kinetic Model and Ozone Isopleth Package for Research de la Agencia de Protecci�n Ambiental de los Estados Unidos y el modelo Statewide Air Pollution Research Center, que incluye reacciones t�rmicas y fotoqu�micas que sirven para reproducir los escenarios estudiados y estimar la reactividad. El modelo se aplic� a los resultados experimentales obtenidos en el Aeropuerto Santos Dumont, ubicado en la ciudad de R�o de Janeiro, Brasil.
