The visibility, air quality and gaseous characteristics of Seoul, Korea, in March 1993 to June 1994 were studied. Results showed that the occurrence of visibility impairment episodes is strongly associated with the concentration of fine particles and the fraction of ionic species in fine particles. Higher sulfate and nitrate concentrations were found during these smog episodes. A smog episode could be described by high mass loadings of PM3 particles and large fractions of sulfate, nitrate and ammonium ions in the fine particles.
