Air Pollution Indicators

Air Pollution Indicators. An indicator should. Be representive for environmental conditions; be simple and easy to interpret; shows trends over time; shows contributions from sectors or individual components; be consistently used within the DPSIR-chain; have a target value.

  1. Air Pollution Indicators

  2. An indicator should... • Be representive for environmental conditions; • be simple and easy to interpret; • shows trends over time; • shows contributions from sectors or individual components; • be consistently used within the DPSIR-chain; • have a target value.

  3. Assessment information D riving forces (economic sectors: transport, combustion, solvent use) P ressures (emissions: VOC & NOx) S tate (air quality: ozone exceedances) Impacts (health, ecosystems, materials) Responses (policies, measures)

  4. Indicators will form building blocks of main EEA reports (Environmental Signals, TERM/EERM, Kiev, ..) • Core set vs sub-sets to support thematic reports

  5. Indicators - current set • Climate change • policy update • emissions CO2 & non-CO2 • temperature/precipitation change • Stratospheric Ozone • ozone column • potential Cl • UV • production ODS, HCFC

  6. AP Indicators - current set Focus on • Pressure & State • Urban Air Quality • Acidification • Pollutants from first DD + Ozone • retrospective (Env Sign) • Policy Update

  7. Sources of AP indicators • CORINAIR • AIRBASE in addition: • Auto Oil 2 • ShAIR

  8. AP Indicators - current set • Emission indicators • information on trends (1980-present) • information on sector contributions • aggregated information on theme: • ground-level ozone • acidification and eutrophication • pm10 exposure

  9. Emissions of O3-precursors

  10. Emissions of O3-precursors

  11. Evaluation of NOx emissions

  12. Environmental Policy

  13. Environmental Policy

  14. Pressure Problems ? • PM10/PM2.5 -emission data • Consensus on aggregation procedure • Indicator for Urban Air Pollution? • Missing years (now simple interpolation) • Emissions of toxic pollutants (HM, POP)?

  15. Air Pollution Indicators • Air Quality • (urban) population exposure to • ozone • SO2 • NO2 • particulate (PM10) • exceedance of critical loads (EMEP) • acid • nitrogen input

  16. Env Signals: UAQ • SO2, particulate (TSP, BS, PM10), NO2, O3 • observed data (AirBase, O3-dir) • counting exceedance days • not fully in line with DD • short term limit values

  17. Urban AQ: NO2

  18. Urban AQ: Ozone

  19. TERM: UAQ

  20. State problems ? • Spatial coverage • missing regions • urban or/and rural • harmonisation of MM • stable network • temporal: historic data • most critical LV • model vs measurement

  21. Impact indicators • Ecosystems: • exceedances of critical loads/levels • Human health • ??????????
