Abstract
This study investigated the effect of phosphorus fractionation on the phosphorus release from the sediments of Juksan reservoir in Yeongsan River. The field sediments were collected, incubated, and analyzed with respect to phosphorus fractionation of sediments and total phosphorus (TP) of overlying water after 7 days. The total amount of inorganic phosphorus of YS2 site was higher than YS1 site. Al-P and Fe-P were major constituents of inorganic phosphorus. During the incubation, Al-P, Fe-P and Ca-P were increased and Red-P was decreased at both sites. YS1 site showed increased TP concentration of overlying water, however, YS2 had opposite trend during the incubation. Counting on the particle size distribution of YS1 and YS2, particle size distribution is major factor to control the TP concentration of overlying water. There were positive relationship between Fe-P and TP and negative relationship between Red-P. From the results, it is essential to continuously monitor the sediment phosphorus fraction in order to control the TP concentration of the water.
