백두산 화산재 유해성분 추정을 통한 팔당댐 유역 수질영향 평가

국문 초록 (Abstract)

백두산 분화 시 분출되는 화산재에 의한 수질환경 변화에 대응하고자 본 연구에서는 백두산 화산재 성분을 추정하고, 화산재 퇴적 두께에 따른 수질 농도변화를 분석하였다. 백두산 화산재 성분을 추정하기 위해 주요 해외 화산의 마그마 성분과 백두산의 마그마 성분을 비교하여 유사한 화산을 선정하고, 해당 화산에서 분출한 화산재의 성분을 백두산의 화산재 성분과 유사한 것으로 가정하였다. 화산재 유해성분에 의한 수질 농도변화를 분석하기 위해 화산재 퇴적 두께에 따른 유해성분 농도의 증감을 분석한 후, 국내 먹는물 수질기준과 비교함으로서 수질환경에 대한 영향 유무를 평가하였다. 연구 결과, 알루미늄, 카드뮴, 불소, 철, 납, 마그네슘, 염소와 스트론튬 등이 취수원에 영향을 미치는 것으로 나타났으며, 이 중 카드뮴, 불소, 철, 납, 마그네슘의 경우에는 수질관리 및 화산분출 시 관리가 필요할 것으로 분석되었다.

Volcanic ash components of Mt. Baekdu were estimated to response the change of water quality environ-ment affected by Mt. Baekdu volcanic ash ejected during eruption. Then the change of water concentrations according to the sedimentation of volcanic ash components were analysed. To estimate volcanic ash components of Mt. Baekdu, similar volcanos were selected through the comparison of main foreign volcano’s magma type and the selected volcanic ash components supposed as Baekdu Mountain’s. To analyse the change of water concentrations, the change of harmful components affected by volcanic ash sedimentation were analysed and the results were compared with domestic drinking water quality standard. As the result, Al, Cd, F, Fe, Pb, Mg, Cl and Sr could affect to water quality. Among those components, concentrations of Cd, F, Fe, Pb and Mg were estimated to exceed the drinking water quality standard.
