Abstract

Atmospheric gases and particulates were collected using four-stage filter-pack in Chunchon from January through December in 1999. Particulate SO42- and NO3-, and gaseous HNO3, SO2 and NH3 were analyzed. Annual average concentration of SO42-(S), NO3-(S), HNO3 (g), SO2(g) and NH3(g) were 5.75μg/m3, 4.98μg/m3, 0.33ppb, 1.52ppb and 7.25ppb, respectively. Annual dry deposition fluxes were estimated using the measured concentration and dry deposition velocity published by other research group. Annual dry deposition of S was 287kg · (km)-2·y-1, which accounted for about 30% of total S deposition. For N deposition, dry deposition is predominant; about 70% of total N deposition was through dry process mostly as forms of NH3 and HNO3.
