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.

본 연구는 영산강 죽산보 상류 퇴적물을 대상으로 퇴적물에 존재하는 무기인의 존재형태를 파악하고 수체에 미치는 잠재적인 가능성을 예측해보고자 실험실 실험을 진행하였다. 이를 위해 현장 퇴적물을 채취하여 7일 동안 배양실험을 진행하였고, 배양 후 퇴적물의 존재형태별 인 및 수층의 총인을 측정하였다. 무기인의 총량은 YS1 지점보다 YS2 지점에서 더 많았으며, 존재형태별 인 중 Al-P와 Fe-P의 비율이 높았다. 두 지점 퇴적물 모두 배양 초기에 비해 배양 7일 후 Al-P, Fe-P 그리고 Ca-P는 증가하였으며, Red-P는 시간에 따라 감소하는 경향을 보였다. 수층의 총인 농도는 YS1 지점에서 배양시간에 따라 증가하는 경향을 보였고, YS2 지점에서는 배양 7일 후 초기에 비해 총인의 농도가 감소하였다. 퇴적물 입자가 조밀한 YS1 지점이 YS2 지점에 비해 수층 총인 농도가 높은 결과로부터 수층의 총인 농도 변화는 퇴적물의 입도에 영향을 받음을 알 수 있었다. 존재형태별 인 중 Fe-P는 수층의 총인 농도와 음의 상관관계를, Red-P는 양의 상관관계를 보였다. 본 연구의 결과로부터, 수층의 총인 농도를 관리하기 위해서는 퇴적물 인의 존재형태별 특성을 지속적으로 모니터링 하는 것의 필요성을 확인할 수 있다.
