Aplicación de un modelo matemático para determinar la difusión de contaminantes atmosféricos bajo condiciones físicas y meteorológicas de la ciudad de Riobamba

Abstract

The purpose of the research was to apply a mathematical model to determine the atmospheric pollutant diffusion under physical and meteorological conditions of Riobamba. For this, it was necessary to use the Gaussiano mathematical model that is the same time it allows calculating the concentration of this pollutants at ground level. The determination of atmospheric pollutants was carried out through an ISCLT –based program ISCLT (Industrial Source Complex Short Time), this model is approved by the EPA (Environmental Protection Agency) and distributed for free. This model is used for calculating average concentrations at ground level in monthly, quarterly and annual periods from the reception of source meteorological data and conditions in the area. The results are: maximum concentrations in the south west part of Riobamba, this concentrations were compared with the existing norms. It is concluded that the spread of pollutants is principally directed towards the south west due to the physical and meteorological conditions of the city. It is recommended to use these data as a base for controlling the air quality in Riobamba.
