Abstract
El modelamiento de la dispersión geográfica de PM10 producida por el sector ladrillero en el distrito de San Jerónimo, utilizando el software AERMOD VIEW10 fue realizado. De acuerdo con el protocolo USEPA, y siguiendo el programa Aermod View se realizó la medición de parámetros y valores in situ, en un horno ladrillero: dimensiones del horno, velocidad de salida del penacho, temperatura de salida de los gases, consumo de combustible, tiempo de cocción y materia prima. Los valores fueron ingresados al programa Aermod View en su versión 9.9.0 determinando el tipo de terreno e identificando las fuentes de emisión. Los resultados se muestran en el mapa de dispersión de PM10 del sector ladrillero, donde se identificó que el punto de monitoreo CA-SJ-01 presenta una concentración de 133.12 µg/𝑚3 siendo el punto que sobrepasa los ECA para aire. Se concluye que existe una relación directa entre la dispersión de los contaminantes y los parámetros meteorológicos de velocidad y dirección del viento, validando el monitoreo de calidad de aire realizado por el OEFA.
Modeling of the dispersion of PM10 from the brick kiln of the district of San Jerónimo Cusco. The modeling of the geographical dispersion of PM10 produced by the brick sector in the San Jerónimo district, using the AERMOD VIEW10 software was carried out. In accordance with the USEPA protocol, and following the Aermod View program, the measurement of parameters and values was carried out in situ, in a brick kiln: dimensions of the kiln, plume exit velocity, gas exit temperature, fuel consumption, cooking time and raw materials. The values were entered into the Aermod View program in version 9.9.0, determining the type of terrain and identifying the emission sources. The results are shown in the PM10 dispersion map of the brick sector, where it was identified that the monitoring point CA-SJ- 01 presents a concentration of 133.12 µg/𝑚3, being the point that exceeds the ECA for air. It is concluded that there is a direct relationship between the dispersion of pollutants and the meteorological parameters of wind speed and direction, validating the air quality monitoring carried out by the OEFA.
