Abstract

n situ sediment oxygen demand (SOD), which takes place with the uptake of dissolved oxygen for biological metabolism and chemical oxidation in sediments, ranged from 1.57 to $12.55\;mg\;O_2\;m^{-2}\;h^{-1}$ in onshore of Lake Paldang from April to November 1999. SOD was influenced by the amount of organics and oxygen diffusion. Comparing the oxygen demands partitioning between overlying water and sediment during initial phase, SOD accounted for $63.8{\sim}94%$ of total oxygen demand in Lake Paldang. The chemical SOD and nitrogenous oxygen demand ranged $1.2{\sim}18.3%$ and $8.3{\sim}51.7%$ of total SOD, respectively. This result indicated that SOD in Lake Paldang occurred mainly by aerobic respiration and nitrification. Although the flow velocity could increase SOD within a certain limit, the effect of sediment depth on SOD was dependent on physicochemical properties of the sediment. This study showed that SOD can represent a significant portion of the total oxygen up-take in Lake Paldang. Therefore, the assessment of SOD might be necessary for the control of water quality.

초록(한글) 입력자 : 퇴적층 산소요구는 수중의 퇴적층에서 생물학적 호기성 대사와 화학적 산화에 소모되는 용존산소량으로 1999년 4월부터 11월 사이에 팔당호 현장에서의 SOD는 조사시점에 따라 $4{\sim}5$ 시간동안 $1.57{\sim}12.55$ mg $O_{2}m^{-2}h^{-1}$로 나타났다. 또한 SOD는 퇴적유기물의 양과 퇴적층 내로의 산소 확산의 영향이 컸다. 초기 30분 동안에 물과 퇴적층의 산소요구를 비교하면 SOD가 수층 전체 산소소모의 $63.8{\sim}94$%를 차지하였다. 실험실 내의 SOD 측정에서 화학적 퇴적층 산소요구는 크게 일어나지 않았으며 퇴적층의 탄소성 산소요구는 전체 SOD보다 적게 나타났다. 이 결과로부터 팔당호의 SOD는 주로 생물학적 산소요구에 의한 것이며 질화작용에 의한 산소요구가 SOD에 큰 비중을 차지함을 알 수 있었다. 퇴적층의 두께가 SOD에 미치는 영향은 퇴적물의 특성에 크게 좌우되며 유속을 2배로 빠르게 한 경우에는 SOD가 $1.4{\sim}1.9$배 증가하였다. 본 연구를 통해 SOD가 수층의 용존산소를 감소시키는 주요한 요인임을 알 수 있었으며 상수원으로 이용되는 호수에서 이를 감안한 수질관리가 적용되어야 할 것으로 판단된다.
