【 摘 要 】

The contribution of different anthropogenic source-sectors on ozone mixing ratios and PM_2.5 concentrations over Europe is assessed for a summer month (July 2006) using the US Environmental Protection Agency’s (EPA’s) Models-3 framework and the Netherlands Organization for Applied Scientific Research (TNO) anthropogenic emissions for 2006. Anthropogenic emission sources have been classified into 10 different Standard Nomenclature for Air Pollution (SNAP) categories. The road transport category, which is mainly responsible for NO_X emissions, is estimated to have the major impact on Max8hrO₃ mixing ratio suggesting an increase of 6.8% on average over Europe, while locally it is more than 20%. Power generation category is estimated to have the major impact on PM_2.5 concentrations since it is the major source of SO₂ emissions, suggesting an increase of 22.9% on average over Europe, while locally it is more than 60%. Agriculture category is also contributing significantly on PM_2.5 concentrations, since agricultural activities are the major source of NH₃ emissions, suggesting an increased by 16.1% on average over Europe, while in regions with elevated NH₃ emissions the increase is up to 40%.
