Verificación de la altura para la medición de PM10 y PM2.5 en calidad del aire como parte del cumplimiento del objetivo y características de los sistemas de vigilancia de calidad del aire (SVCA)

Abstract

This work establishes the difference in concentration of particulate material (PM10 and PM2.5) At different heights (2m and 10m) in order to find if there is any type of incidence at the time of making a measurement in said range of heights which are those defined in the Part40-CFR of the EPA for the installation of equipment and implementation of an air quality monitoring system (SVCA). in order to verify the appropriate measurement height for a traffic and environmental SVCA in the city of Bogotá. The measurements made at the BOSA PORVENIR and ASAB headquarters of the district university resulted in the collection of 159,322 PM10 and PM2.5 measurement data. for the two aforementioned locations obtained in a period of 7 months where it is found that the concentration trend is greater than 2m in height and exceeds more than 60% of the total data indicating that by month of corresponding study for each parameter more half of the study follows the aforementioned behavior, for the future headquarters it was possible to establish that although the concentration differences are greater with peaks up to 40 µg / m3 difference in height for the PM10 parameter. mostly they are not above the norm, for parameter PM2.5. it was concluded that the highest concentrations occur at night and early in the morning where the highest student influx is recorded, for headquarters of arts, a higher frequency of concentration records was recorded in a smaller number of concentration intervals, which indicated low concentrations for the two parameters in general, concentrations greater than 2m were recorded in a range of 0 to 15 µg / m3.
