Air Quality Status In Greater Thessaloniki Area And The Emission Reductions Needed For Attaining The Eu Air Quality Legislation

摘要

This paper aims at imprinting the urban air quality status and assessing the impact of various emission reduction scenarios on the photochemical and paniculate matter air pollution levels in the Greater Thessaloniki Area, Greece. In particular, it is investigated under which conditions compliance with the EU air quality legislation can be achieved. For this purpose, the Ozone Fine Structure model is applied for a full calendar period (reference year 2002), as well as for specific scenarios, corresponding to predefined emission reductions for 2010. The model results for photochemical and paniculate matter air pollution levels in 2002 agree fairly well with the observations. Predictions for 2010 indicate that significant improvement towards the EU legislation requirements can be achieved for certain emission reduction scenarios. However, an overall strategy will also have to include additional local scale measures.
