금강하구호 低泥의 燐 특성에 관한 연구 = A Study on the Phosphorus Characteristics of Sediments in Keum River Estuary Reservoir

다국어 초록 (Multilingual Abstract)

This study was accomplished to investigate P characteristics from sediments seasonally and apply the basic water quality data for industrial water supply in Keum River estuary reservoir. The release amount of TP was about 1,174 mgTP/kg in summer, and NAI-P, which was formed about 43.5% in TP, was appeared higher release portion than other season. In summer, which the temperature is high and DO concentration is low, NAI-P will be release with internal pollution source. it was also found that the portions of PIP(Particulate Inorganic Phosphorus) and POP(Particulate Organic Phosphorus) were about 41.6% and 58.4% in sediments, respectively. Therefore, the amount of P adsorbed to soil particles is larger than the P adsorbed to heavy metal from sediments in Keum River estuary reservoir.
