                         decreased all vehicle activity in Brazil. We evaluated the 
                         concentrations of criteria pollutants in seven different 
                         microenvironments during this period in the Sao Paulo Megacity. 
                         Results were evaluated by violin plots, the Kruskal-Wallis test 
                         and diurnal cycles, comparing the year 2018 to an average of 4 
                         previous years. Primary pollutants (CO and NO) decreased by 50% in 
                         2018, predominantly in roadside (RDS) locations. NO2, PM10, and 
                         PM2.5 did not decrease as much, suggesting the relevance of 
                         secondary reactions and other sources (ex: fires). Ozone increased 
                         significantly (about 30-50%), possibly due to favourable 
                         atmospheric conditions (solar radiation) and changes in the 
                         NOx/VOCs ratio caused by the decrease in NO. Our findings help to 
                         better assess the role of vehicular emissions and provide insights 
                         on the impacts of interruption of activities (ex: during 
                         lockdowns) over air quality in metropolitan environments.",
