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.
Assessment information D riving forces (economic sectors: transport, combustion, solvent use) P ressures (emissions: VOC & NOx) S tate (air quality: ozone exceedances) I mpacts (health, ecosystems, materials) R esponses (policies, measures)
Indicators will form building blocks of main EEA reports (Environmental Signals, TERM/EERM, Kiev,..) Core set vs sub-sets to support thematic reports
Indicators - current set Climate change –policy update –emissions CO2 & non-CO2 –temperature/precipitation change Stratospheric Ozone –ozone column –potential Cl –UV –production ODS, HCFC
AP Indicators - current set Focus on Pressure & State Urban Air Quality Acidification Pollutants from first DD + Ozone retrospective (Env Sign) Policy Update
Sources of AP indicators CORINAIR AIRBASE in addition: Auto Oil 2 ShAIR
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
Emissions of O3-precursors
Evaluation of NOx emissions
Environmental Policy
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)?
Air Pollution Indicators Air Quality –(urban) population exposure to ozone SO2 NO2 particulate (PM10) –exceedance of critical loads (EMEP) acid nitrogen input
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
Urban AQ: NO2
Urban AQ: Ozone
TERM: UAQ
State problems ? Spatial coverage –missing regions –urban or/and rural harmonisation of MM stable network temporal: historic data most critical LV model vs measurement
Impact indicators Ecosystems: –exceedances of critical loads/levels Human health –??????????
