Evaluación de las tendencias de calidad del aire en la zona metropolitana del valle de Toluca durante los años 2000 – 2013

Abstract

This current work was carried out jointly with the Research Center Automotive Mechatronics belonging to Technological of Monterrey-Toluca Campus, under the direction of PhD. Jenny Diaz Ramirez with the cooperation of PhD. Jose Huertas Cardozo and PhD. Gabriel Cervantes Bello; as part of the Characterization of Air Quality in the Metropolitan Area of Toluca by analyzing the air monitoring database to verify compliance with the Mexican Air Quality Standards. The analysis was performed based on an hourly database average concentration of air pollutants constantly supervised in seven environmental monitoring stations of the Metropolitan Area of Toluca from 2000 to 2013. The analysis of the databases were performed in the study period from each of the criteria pollutants such as: O3, PM10, SO2, CO and NO2; the value of the monthly, annual and daily averages were calculated for each pollutant in turn to verify compliance with the Official Mexican Air Quality Standards (NOMs). These NOMs establish the maximum permissible limits of concentration in the atmosphere for each one of the criteria pollutants. A multivariate linear regression model was proposed to predict the daily average concentration of pollutant that creates more problems in the ZMVT. The values of daily concentration of PM10 can be obtained with the regression model using meteorological variables that are also measures in the automatic air quality monitoring network of ZMVT.
