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/m3, and mean value was 1. 2ng/m3 (n=4), at the rural area II (Buyeo) ranged from 0.8 to 5.1 ng/m3, and mean value was 2.Ong/m3 (n=8), at the area of the center of urban (Jong-ro 3 Ga, Seoul) ranged from 22.7 to 43. ing/m3, and mean value was 35. lng/m3 (n=12), at the residential area I (Galak Dong, Seoul) ranged from 2. 2 to 5. ing/m3, and mean value was 3. 5 ng/m3 (n=6) at the Chung-Ang University (Heukseok Dong, Seoul) ranged from 2. 2 to 176. 2 ng/m3, mean value was 36. 8 ng/m3 and median value was 16.0 ng/m3 (n=188), at the residential area II (Goowal Dong, Inchon) ranged from 6. 4 to 20.7 ng/m3, and mean value was 13.1 ng/m3 (n=10), and at the industrial area (Songhyun Dong, Inchon) ranged from 13.9 to 88. 3 ng/m3, and mean value was 38. 9 ng/m3 (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.
