Item Metadata only Contaminación del aire a filo de calle, caso estudio PUCE sede QuitoChuquer Sola, David SebastiánAir pollution on street level in one of high traffic zones of the Metropolitan District of Quito (DMQ) was studied between March 16 and 22 of 2018 by monitoring gases and particulate matter (PM) with continuous analyzers. During the monitoring period, there were no violations of the air quality environmental regulations; however, the carbon monoxide values obtained in this study were higher than those registered in the DMQ Environment Secretariat’s regional monitoring stations. Time series analysis allowed to understand trends and behaviors of pollutants concentration throughout the day, as well as correlated associating parameters, such as ozone, nitrogen dioxide and PM which behaviors were influenced by the atmospheric conditions and DMQ anthropogenic activity. Additionally, indoors air PM concentration was determined to be higher than outdoors’s, but with similar tendency. Statistical analysis showed correlated parameters groups such as secondary pollutants, temperature and humidity that represented the most influential component. Pollutants concentration depend on day time as well as associated meteorological factors like humidity and temperature, demonstrating that DMQ pollution at street level was a unique study case to understand air pollution in high altitude cities.
