The cyclone/annular denuder system/filter pack sampling system (ADS) was used to collect data set of the acidic air pollutants in the vicinity of industrial complexes in Gwangyang. The data set was collected during sixty differentdays with 24 hour sampling period from January 8, 2008 through November 12, 2008.
The annual mean concentrations of HNO₃, HNO₂, SO₂ and NH₃ in the gas phase were 1.12, 1.40, 10.2 and 1.28 ㎍/㎥, respectively. The annual mean concentrations of PM<SUB>2.5</SUB> (dp＜2.5 ㎛), SO₄<SUP>2-</SUP>, NO₃?, and NH₄? in the particulate phase were 29.2, 8.25, 3.30 and 3.42㎍/㎥, respectively. HNO₃ and NH₃ exhibited higher concentrations during the summer, while HNO₂, PM<SUB>2.5</SUB>, NO₃? and NH₄? were higher during the winter. The highest level of SO₂ was, unlikely, observed in the summer and SO₄<SUP>2-</SUP> was not showed seasonal variation. SO₄<SUP>2-</SUP>, NO₃?, and NH₄? accounted for 49~57% of the PM<SUB>2.5</SUB> mass. SO₄<SUP>2-</SUP> was the most abundant component, which constituted 23~40% of PM<SUB>2.5</SUB>. High correlations were found among PM<SUB>2.5</SUB>, SO₄<SUP>2-</SUP>, NO₃?, and NH₄?.
