碩士 === 國立成功大學 === 環境工程學系 === 104 === This study estimated the effect of PM2.5 control measures on ambient concentration in Taiwan. Air quality model (CMAQ) was conducted to simulate the concentration of PM2.5 under three different control scenarios. Three scenarios were evaluated, which include base case and two controlled cases. The results of PM2.5 concentration simulation showed that the high PM2.5 concentrations were observed in central and southern Taiwan, especially at Taichung and Kaohsiung area. Annual average concentration of PM2.5 for Case A and Case B present 20.1% and 28.8% reduction, respectively, as compared to those of basics case. The results also implied that control NOx emissions may result in significant improvement on airborne PM2.5 concentration in episode day in Taiwan, and control primary PM2.5 emissions may improve airborne PM2.5 concentration in all months. However the result also indicates that the preliminary control plan could not attain the air quality standard. More control measures to reduce much more emissions from various emission sources should be developed in the future.
