The Study on the Seasonal Variations and Chemical Compositions of Atmospheric Deposition Flux Measured with Dustfall around Tae-an peninsula

태안반도주변 강하분진량의 계절변화와 그 성상에 관한 연구

The atmospheric deposition flux was measured with dustfall from July of 1997 to July of 1998 at nine sampling sites located in Tae-an peninsula to examine the seasonal variations. The results showed that the average dry deposition was higher in spring than the other seasons. Thus, it is considered that yellow sand is one major source of the additional deposition flux in spring. There also appeared the higher measurement of deposition at the sites nearby road (like Hagampo, Bangali and Sinduri) in summer, and it is assumed that the heavy traffic caused by summer visitors was the main factor of that. For more accurate study, the qualitiative analysis should be taken on the deposited materials.
