Atmospheric mercury was collected by gold amalgamation method and analyzed by cold flameless atomic absorption spectrometry. The distribution of atmospheric mercury was investigated at seven location (rural I, II, industrial I, II, University and the center of urban) The amount of atmospheric mercury collected at the rural area I (Mt. Seolack) ranged from 0.7 to 1.8ng/$m^3$, and mean value was 1.2ng/$m^3$ (n=4), at the rural area II (Buyeo) ranged from 0.8 to 5.1 ng/$m^3$, and mean value was 2.0ng/$m^3$ (n=8), at the area of the center of urban (Jong-ro 3 Ga, Seoul) ranged from 22.7 to 43.1ng/$m^3$, and mean value was 35.1ng/$m^3$ (n=12), at tae residential area I (Galak Dong, Seoul) ranged from 2.2 to 5.1ng/$m^3$, and mean value was 3. 5 ng/$m^3$ (n=6) at the Chung-Ang University (Heukseok Dong, Seoul) ranged from 2.2 to 176.2 ng/$m^3$, mean value was 36.8 ng/$m^3$ and median value was 16.0 ng/$m^3$ (n=188), at the residential area II (Goowal Dong, Inchon) ranged from 6.4 to 20.7 ng/$m^3$, and mean value was 13.1 ng/$m^3$ (n=10), and at the industrial area (Songhyun Dong, Inchon) ranged from 13.9 to 88.3 ng/$m^3$, and mean value was 38.9 ng/$m^3$ (n=12). The behavior of atmospheric mercury concentration at Chung-Ang University showed high in day time and summer, but low in night-time and winter.
