| Summary: | 碩士 === 國立成功大學 === 環境工程學系 === 104 === This study collect and arrange the data by USEPA and domesteic research about the emission factor of using ethanol-blended gasoline in light duty gasoline vehicle (LDGV), light duty gasoline truck, and scooter, then modify the gridded line sources emissions in TEDS8.1 which is used in Models-3/CMAQ to simulate the impact of using E3, E5, E10 gasohol within 2010 April and October in Taiwan. The simulation result shows that average PM2.5 concentration in E3, E5, E10 gasohol scenarios will variate 0.00, 0.00, 0.03 ug/m3 respectively; April’s daily average ozone concentration in E3, E5, E10 scenarios will repectively rise 0.11, 0.12, 0.18 ppb, which October’s result are repectively 0.08 ,0.09, 0.13 ppb; April’s continuous 8 hours average ozone concentration in E3, E5, E10 scenarios will repectively rise 0.10, 0.10, 0.14 ppb, which October’s repectively rise 0.07, 0.06, 0.09 ppb; April’s daily maximum ozone concentration rise respectively 0.12, 0.10, 0.12 ppb, but only 0.07, 0.05, 0.04 ppb in October. The ratio of [H2O2]/[HNO3] indicator shows that Taipei and east area of Taiwan are more likely to be NOx-control region, which implies the different cause in rising ozone concentration. The concentraion average variation in each hour of ozone and NOx implies the main reason in the increasing ozone should be the titration between ozone and NO, however, Kaohsiung and Pintung have much higher hourly ozone increase at noon because of the precursor from Tainan and itself, which can be obsevated by simulation of HYSPLIT forward trajectory.
