    摘要: 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).
