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，

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).
