The distribution of total mercury in the ambient atmosphere of Seoul during the period April, 1988 to March, 1989 was evaluated. The method used in this study involves absorption of gaseous mercury species in the atmosphere on Chromosorb^R A coated with gold based on gold amalgamation. The trapped mercury was thermally released and determined by atomic absorption spectrometry. Air sampling was carried out at 8 points spread over Seoul and classified into 3 groups-within a 5 km, 10 km, 15 km radius from the city center. Three rural points which represented sparse population and little industrial activity were also studied for comparison. The atmospheric mercury concentrations in Seoul ranged from 5.0 to 88.8 ng・m^<-3> (mean 25.1 ng・m^<-3>), while those in rural areas ranged from 1.0 to 7.0 ng・m^<-3> (mean 3.8 ng・m^<-3>). The distribution of mercury depending on the distance from the urban center was evaluated and seasonal, diurnal altitudinal variations of atmospheric mercury were also described.
