Département Surveillance de la Qualité de l’Air AQ monitoring, who does what ? AQ monitoring, who does what ? NATIONAL LEVEL Ministry of Environment (MEDD) ADEME (general monitoring policy) ( (general monitoring policy) (Technical coordination National Data Base Research Programmes ) LOCAL LEVEL 40 Air Quality Monitoring Entities (AQME) ( local implementation of monitoring, information...) National AQ monitoring Laboratory LCSQA (technical support : metrology, modeling and quality assurance)

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, monitoring devices

Département Surveillance de la Qualité de l’Air 1/ National calibration chain Operational QA/QC procedures in AQME National reference standards (level 1) Regional reference standards (7 ) (level 2) Stations working standards (level 3) Transfer standards 1->2 and 2->3 SO2, NO-NO2, O3, CO, benzene
