Abstract

In this study, the chemical components (pH, $HCO_3{^-}$, $Cl^-$, and $SO_4{^{2-}}$) of water sources (surface water, groundwater, and spring water) in 1930s were compared to those in the period of 1985-1992 in Jeju Island. By the comparison, pH values and $Cl^-$, and $SO_4{^{2-}}$ concentrations in 1930s appeared similar to those in the second period (1985-1992) while $HCO_3{^-}$ increased about the six times in the second period. Such a great increase of $HCO_3{^-}$ concentration may be caused by the increase of carbon dioxide in the atmosphere due to industrialization.

본 연구에서는 1930년대 제주도의 수원(지표수, 지하수, 용천수)의 수질(pH, $HCO_3{^-}$, $Cl^-$, $SO_4{^{2-}}$)과 약 50년 후(1985~1992년)의 수질자료를 비교하였다. 그 결과 두 시기 사이에 pH값과 $Cl^-$, $SO_4{^{2-}}$의 농도는 큰 차이가 없었으나, $HCO_3{^-}$의 농도는 두 번째 시기(1985~1992년)에서 6배 정도 증가하였다. 이러한 $HCO_3{^-}$ 농도 증가는 산업화에 따른 대기 중 이산화탄소량의 증가에 의한 것으로 추측된다.
