  2. Overview • VMM • Air Quality Networks • State of the Environment - Air • PM 2.5 2

  3. VMM - mission VMM = internally independent agency with powers of jurisdiction (°1990) Founding Decree of 23 December 2005: mission “contribute to • the realisation of the objectives of the environmental policy by preventing, limiting and eliminating the harmful effects to water systems and the atmosphere and by reporting on the state of the environment and • the realisation of the objectives of integrated water management.” 3

  4. VMM tasks related to air • Drawin up an Emission Inventory • Air Quality Monitoring Networks • Advising • On the granting of environmental permits • Spatial Planning • Input • State of the Environment Report (MIRA) • Environmental Policy Plan (MINA) 4

  5. VMM tasks related to air • Input: International Policy regarding Air • IRCEL: Interregional Cel for the Environment • Calibration • Database • Reporting to the EU commission • Smog alerts for Belgium • Information to the public, reports, • Websites • www.vmm.be • www.irceline.be 5

  6. Air Quality Monitoring Networks • Telemetric network (37 stations) • Local networks (29 stations) • Mobile laboratory • Network heavy metals (20 stations) • Acid deposition (9 stations) • Organic measurements 6

  7. Air Quality Monitoring Networks • Telemetric network (37 stations) • SO2, NOx, O3, PM10 and PM2.5, carbon, BTEX, CO, black smoke • meteo 7

  8. Telemetric Network stations 2007 8

  9. Measurement station 9

  10. Automatic monitors SO2 – analysis UV-fluorescence Fine Dust analysis b-absorption 10

  11. Air Quality Monitoring Networks • Local networks (23 stations) • SO2, NOx, PM10 en PM2.5, carbon, black smoke, BTEX, VOC • Hg • HF (stopped in 2008) 11

  14. Measurement station: local network 14

  15. Local network in 2007 15

  16. Air Quality Monitoring Networks • Mobile laboratory • SO2, NOx, O3, PM10, PM2.5 • meteo 16

  17. Air Quality Monitoring Networks • Network heavy metals • particles in suspension small particles ~ PM10 20 stations • deposition of particles bigger particles 10 jauges: non-ferro and background 17

  18. Monitoring heavy metals in particulate matter • Sites (2009) • 20 stations equipped with PM10-Samplers • Industrial • Non Ferrous : Hoboken and Beerse • Steel: Zelzate and Genk • Urban : Antwerp ( more > 500.000 citizens) and Ghent • Rural : Koksijde near the North Sea Coast 18

  19. Monitoring heavy metals in PM10 : 2007 19

  20. Sampling: Leckel PM10 sequential sampler 20

  21. Heavy metals • PW2400 instrument WD-XRF • 2 tubes/ measurement time • Rh tube: As, Cu, Cr, Mn, Ni, Pb, Zn : 12 min per sample • Cr tube: Cd and Sb 3 min per sample • Epsilon 5 -3D-ED-XRF toestel • Gd buis with different targets • Measurement time 30 min per sample 21

  22. Air Quality Monitoring Networks • Acid deposition • 9 monitoring stations • Natural reserves • Rainwater: anion + cations nitrate, sulphate, ammonium • Dry deposition: NH3, NOx, SO2 by passive samplers + depositon speed 22

  23. Air Quality Monitoring Networks • Organic measurements • VOC - Volatile Organic Compounds 8 stations 50 components • PAH - Poly Aromatic Hydrocarbons 6 stations, 10PAH + 5 nitro - PAH • Pesticides in rainwater • Dioxin and PCB deposition in 50 stations 23

  24. VOC • Monitors:, BTEX, VOC • Manual sampling • 24hr sample every 4th day • Carbotrap • GC-MS analysis 24

  25. PAH • Low Volume Sampling : 48 m³/day for PAH • High volume sampling: 120 m³ for nitro-PAH New method: absorption tubes • Quartz fibre filters : 47 mm diameter • HPLC with fluoresence detection 25

  26. Dioxine deposition Sampling • Bergerhoff deposition jar glass jar : 9,5 cm inner diameter 20 cm height • Period 28 ± 2 days Analysis • Pretreatment Extraction with dichloromethane • Analysis HRGC-HRMS 26

  27. EU limit values – 2008/50/EC avg time 1-hourmax 8-hour 24-hours year SO2350 24x yr 125 3x yrNO2200 18x yr 40 (2010)PM1050 35x yr 40Pb0,5 CO10 000 Benzene5 (2010) 120 25x yr O3 3y_avg Target Value (2010) (concentrations in µg/m³) 27

  28. EU target values – 2004/107/EC 28

  29. Actual situation 2007 PM10 • Yearly L.V. no exceedances, except Oostrozebeke • Daily L.V. many exceedances • 2008 favourable 29

  30. Exceedances of daily limit value PM10 30

  31. PM10: yearly mean 2007 31

  32. Evolution PM10 yearly mean Back-ground level: 30 µg/m³ 32

  33. PM2,5 yearly mean2004 - 2007 Levels in Flanders: 20 – 25 µg/m3 33

  34. Actual situation 2007 NO2 • Yearly L.V. 2010 • Exceedances in Antwerp agglomeration/harbour • Study with passive samplers in 2004: also exceedances in cities: Ghent, Leuven, Hasselt • Probably also in other traffic intense environments t.e. Mortsel • New study with passive samplers will be planned for 2010 34

  35. NO2: yearly mean 2007 35

  36. Evolution NO2 yearly mean Increase in industry in 96-97 due to extra stations 36

  37. Actual situation 2007 SO2 ,benzene, CO • No exceedances Benzo – α – pyrene • No exceedances, however reference method gives an underestimation Pb, Cd, As, Ni • Local problems around non – ferro resp. steel industry 37

  38. Yearly mean benzene 2007 38

  39. Ozone: Protection human health 2007 Mean Flanders : 887 µg/m³.hr MLTD (2010) : 5800 µg/m³.hr 39
