Abstract:	石化產業煉製過程與石化燃料燃燒會將含氨物種及硫物種，如H2S、SO2、NOX、 HNO2、HNO3及NH3，其逸散及直接排放，污染大氣環境。由SOR(硫氧化比率)及 NOR(氮氧化比率)發現，SOR高於0.4及 NOR高於0.15時，所代表光化反應相對強烈，其天氣狀態為相對溼度低且當時之O3 濃度較SOR及NOR低時為高。此外，SOR 高時風速強烈，但NOR高時其風速較低，顯示硫物種藉較遠處傳輸氧化轉化成氣膠硫酸鹽，但氮物種由氣態NO2轉化成氣膠 NO3 -，多為交通使用之石化燃料污染及滯留轉化。 and the application of fossil fuel were the one of the main sources of air pollution. The N-species and S-species, for example, H2S, SO2, NOX, HNO2, HNO3 and NH3, were brought into the atmosphere directly and indirectly. It was found that a SOR (sulfur oxidation ratio) value of >0.4 and a NOR (nitrogen oxidation ratio) value of >0.15 represented a relatively strong photochemical reaction, low relative humidity, and high O3 concentration. Additionally, strong wind speeds led to a high SOR value, but weak wind speeds led to a high NOR value. This demonstrates that the gaseous S species (SO2) that form sulfate aerosols are transported from far away, whereas the N species that form gaseous NO2 and subsequently NO3 - are of local origin (due to local traffic pollution emissions leading by the application and combustion of fossil fuel).
