3. Département Surveillance de la Qualité de l’Air Air quality monitoring system Their mission:  to measure  to forecast  to inform (web, local authorities) They measure everyday :  regulated pollutants (SO2, NO2, O3, PM10, Pb, benzene, CO)  «new» pollutants (heavy metals, PAH, PM2.5, VOC, …) 40 local air quality monitoring network entities ~700 monitoring stations, 2 500 monitoring devices
