In order to understand chemical characteristics and formation of dewfall in Busan, we analysed monthly distribution of dewfall, and investigated its chemical composition of dewfall. This study used the modified teflon plate (1m × 1m) at Jangyongsil science high school from June 2005 to October 2005. In order to estimate qualitatively water soluble components, IC, ICP and UV methods for water soluble ions are also used respectively. Dewfall amount of sampling periods (26 day) collected 1.29 ㎜. Distribution of water soluble ions in dewfall founded the highest concentration (81.3 μeq/ℓ for NO3-, 146.6 μeq/ℓ for SO42-, and 114.3 μeq/ℓ for nss-SO42-) during the June. pH was the lowest by 5.12 June, and October (pH 6.68) by most high and average pH was 5.46. Monthly equivalent ratio of [SO42-]/[NO3-] showed the highest value (2.94) during the September, the lowest value (1.77) during the July, and the mean value was 3.45.
