Sumario:Air pollution at the street edge was studied in the Historical downtown of quito (dmq) at a point of high vehicular flow by continuous gas monitoring and particulate material between April 5 and 12, 2018. Time profiles were obtained of the pollutant concentrations and their behavior was explained. The measurements in the study did not exceed the national and international permissible limits of air quality, however abnormal peaks were observed in the case of sulfur dioxide. The cross-correlation of the time series between the data reported by regional stations of the secretary of Environment of the DMQ and the data obtained in this study was evaluated, finding that carbon monoxide presents a higher concentration on the street edge. When performing the main components analysis (pca), several correlated pollutants were determined, which corroborates their formation cycles and de monstrates the influence of meteorological factors on air pollution at the street edge. Finally, it was determined that the concentrations of pm10 in indoor air are higher than that registered in outdoor air in the sampled point.
