AQ monitoring, who does what ? NATIONALLEVEL Ministry of Environment (MEDD) ADEME (general monitoring policy)(Technicalcoordination National Data Base Research Programmes) National AQ monitoring Laboratory LCSQA (technical support : metrology, modeling and quality assurance) LOCAL LEVEL 40 Air Quality Monitoring Entities (AQME) ( local implementation of monitoring, information...)
Air quality monitoring system 40 local air quality monitoring network entities ~700 monitoring stations, 2 500 monitoring devices 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, …)
Operational QA/QC procedures in AQME 1/ National calibration chain 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
Operational QA/QC procedures in AQME 2/ Validation of data 1 - Automatic prevalidation 2 - Technical validation 3 – Environmental survey validation Processed data Extract from guideline « rules and recommandations of AQ data »

The National air quality database in France Objectives : • Data exchange with EEA • Air quality report and assistance in decision making • Scientific research • epidemiology studies, • model validation • Saving data of local network
AQDBusers in France • MEDD/IFEN, Ecole des mines de Douai INERIS, CNRS, AFSSE, INVS, INRA, Météo-France, LHVP, APPA, DRASS… • PREVAIR • Research laboratories : physico-chimistry, climate science, epidemiology • EEA, WHO, Joint Research Centre
Pollutants in AQDB Since 1985 (automatic data): • SO2, NO-NO2-NOx, O3, CO • particules (PM2.5), (PM10) (TSP) • Benzene,Toluène, o,m & p Xylene Each year about 20 millions hourly data (and 80 millions ¼ hourly data) For 2005: “manual” data • PAH (BaP), heavy metal : Cd, As, Ni, Hg, Pb • VOC, Precipitations
Number of data (representativity rate ) Mean (hourly, 8h, daily, mensually, annually) Percentiles (50, 98, 99,9) sur 1h, 24h Number of mean > value Number of days > value Number of exceedences AOT forest and vegetation The available statistics on the AQDB Available on www.atmonet.org
How air quality information is managing in national level ? • Air quality data store in the national database • Exporting data procedures • Quality procedures in AQDB
