Abstract

Volcanic ash components of Mt. Baekdu were estimated to response the change of water quality environment 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.

白頭山 噴火 時 噴出되는 火山재에 依한 水質環境 變化에 對應하고자 본 硏究에서는 白頭山 火山재 成分을 推定하고, 火山재 堆積 두께에 따른 水質 濃度變化를 分析하였다. 白頭山 火山재 成分을 推定하기 위해 主要 海外 火山의 마그마分科 白頭山의 마그마 成分을 比較하여 類似한 火山을 選定하고, 該當 火山에서 噴出한 火山재의 成分을 白頭山의 火山재 成分과 類似한 것으로 假定하였다. 火山재 有害成分에 依한 水質 濃度變化를 分析하기 위해 火山재 堆積 두께에 따른 有害成分 濃度의 增減을 分析한 後, 國內 먹는물 水質基準과 比較함으로서 水質環境에 對한 影響 有無를 評價하였다. 硏究 結果, 알루미늄, 카드뮴, 弗素, 철, 납, 마그네슘, 鹽素와 스트론튬 等이 取水源에 影響을 미치는 것으로 나타났으며, 이 中 카드뮴, 弗素, 철, 납, 마그네슘의 境遇에는 水質管理 및 火山噴出 市 管理가 必要할 것으로 分析되었다.
