4. Conclusions and Recommendations

Contents

1) Tasks of the Department LNE

1. Policy support of the Flemish Minister of the Environment concerning air quality, climate change and the effects of environmental pollution on human health

2. Elaboration of measures against air pollution by e.g. particulate matter, NO2, ozone and heavy metals

3. Specific measures for specific target groups in Flanders, such as the different industrial sectors, traffic and transportation, energy production, agriculture, …

4. Coordination of the Flemish activities in international agreements, e.g. the National Emission Ceilings (NEC) for NOx, SO2, NMVOC’s and NH3 and the emission reduction targets for greenhouse gases

2) Flanders - Europe: PM2.5

2000 2010 2020 Rural PM2,5 concentrations, annual mean [µg/m3] originating from known anthropogenic sources

(excl. sec. org. aerosols)

Source: IIASA - EMEP

3) Attainment of EU Air Quality Levels: NO2 annual mean concentration

Since 2001 increase in NO2 due to higher O3-background and higher NO2/NO-ratio in traffic emissions problems with EU limit value

planned EU limit value: annual mean value 25 µg/m3


Annual mean limit might be attained in busy streets, but only in 2015

4) Conclusions and recommendations for the further work

Conclusion:

Long range transport of air pollutants influences the background concentrations of e.g. O3, NO2 and PM10 in Belgium. Long range transport may even play a role in the non-attainment of EU limit values for certain pollutants.

Recommendation:

Improve the representation of long range transport of air pollutants in the BelEUROS model by using more realistic boundary conditions, especially for O3, NO2 and PM10.
