About the need of controlling the nitrogen oxides to reduce the formation of ozone in the metropolitan zone of Mexico city; Acerca de la necesidad de controlar las emisiones de oxidos de nitrogeno para reducir la formacion de ozono en la zona metropolitana de la ciudad de Mexico

Abstract

The results obtained through the application of an air quality model: AQUAMI for the Metropolitan Area of Mexico City, are presented. The model requires of a photochemical mechanism and the information regarding the total amount of nitrogen oxides and hydrocarbons emitted to the air during that time. In this way the maximum concentrations of ozone that can be reached for the possible ratios of hydrocarbons and nitrogen oxides are obtained. The results are plotted and with them it can be determined that if the nitrogen oxide emission can be diminished, this will impact directly on the ozone emission. Furthermore, the evolution of another product derived of the presence of nitrogen oxides, the peroxiacil nitrate, which is irritant to the respiratory mucosa and to the eyes, is also presented. Through this simulation model the impact derived of the actions aimed at reducing the formation of nitrogen oxides and the release of hydrocarbons at the level of the formed ozone by the sunlight effect. With this basis the ecological impact of the actions such as the following, can be discussed: -improve the combustion process in all thermal equipment. -improve the quality of the fossil fuels utilized. -slightly modify the operational habits in  More>>

[Espanol] Se presentan los resultados obtenidos mediante la aplicacion de un modelo de calidad del aire: AQUAMI, para las condiciones de la zona metropolitana de la ciudad de Mexico. El modelo requiere de un mecanismo fotoquimico y de informacion concerniente a la cantidad total emitida de oxidos de nitrogeno e hidrocarburos, para un periodo especificado, asi como de la forma en que estos compuestos son emitidos a la atmosfera durante ese lapso. Se obtienen asi las concentraciones maximas que puede alcanzar el ozono para las posibles razones de hidrocarburos y oxidos de nitrogeno. Los resultados se presentan en forma grafica, en ella se observa que si puede disminuirse la emision de oxidos de nitrogeno esto impactara directamente en la generacion de ozono. Ademas, se muestra la evolucion de otro producto derivado de la presencia de los oxidos de nitrogeno, el nitrato de peroxiacil, el cual es irritante de las mucosas respiratorias y los ojos. Con el auxilio de este modelo de simulacion se puede explorar el impacto derivado de acciones encaminadas a reducir la formacion de oxidos de nitrogeno y la liberacion de hidrocarburos en el nivel de ozono formado por efecto de la radiacion solar. Con base en lo anterior se puede analizar el impacto ecologico de acciones tales como: - mejorar el proceso de combustion en todos los dispositivos termicos - mejorar la calidad de los combustibles fosiles empleados - modificar ligeramente los habitos de operacion del sector industrial procurando que el uso intensivo de combustibles se desplace hacia las horas de la tarde y noche, cuando la incidencia solar es menor o nula.}
