In the São Paulo metropolitan region, like other world’s big urban centres, environmental monitoring plays a very important role, in view of the degradation of air quality. This work illustrates a case study of continuous monitoring of air pollutants using a differential optical absorption spectrometer (DOAS) associated with an Integrated Environmental Management System (AIRVIRO) in São Paulo, Brazil. The DOAS registered concentrations of benzene, toluene, m-p xilenes, O3, SO2, NO2, NO3, and HNO, and also of a meteorological station continuous data collection. Air quality databases from CETESB – State Environmental Authority were used for reference. Results of days with high concentration averages in winter are related to specific meteorological conditions and local traffic.
