酸性降下物中 窒酸鹽이 住岩湖 水質에 미치는 影響

Abstract

Significant improvement of water quality have not been made despite of point source pollutant loading reduction. This is largely due to the fact that diffuse pollution degrade water quality. Control of loads from non-point sources as well as point sources are needed to improve water quality, this requires exact quantification of non-point sources loads. Quantification and control of non-point sources loads are difficult. Because they are changed by special distribution, topological characteristics, land use and rainfall type. The unit loading method was generally used for quantification of non-point source pollutant loading. Unit loading(kg/ha/day) means effluent loading mass per unit area per unit time. This method is used for average concept, because it is hard to reflect for watershed characteristics and seasonal variation. But in our country, the amount of rainfall is changed by the time of the year. Study area were lake Juam watershed. Analyzing acidic deposition of Juam
