Abstract
The Daechong dam is located nearby Chongju city, and the population alone in the Chongju-Chongwon area is over one half million. It is found that the number of days for fog occurrence after constructing the dam was much fewer than those before constructing it. It appears that the construction of a large dam did not cause to increase in the occurrence of fog in the Chongju area, and that was the increase due to topographical characteristics and wind direction. Low visibility in the Chongju-Chongwon area occurred frequently. In summer, Chongwon recorded more days of poor visibility than those observed at Chongju. It is thought that TSP, and ¾¾¿ÀÅõ were the main constituents of air pollutants causing the reduction in visibility. Those air Pollutants are produced by vehicles and industrial activities in the region.
