초록
대기로 발생하는 메탄가스로 인해 지구온난화는 더욱 가속화되고 있다. 메탄가스의 인위적 발생원 중 광산 이 차지하는 비율은 적지 않다. 그러나 메탄가스의 발생원으로서 광산지역에 대한 연구는 미흡한 실정이다. 본 연구는 광산지역의 인공습지에서 발생하는 메탄에 대한 기초연구로서 메탄발생량을 측정하고 수질특성이 메탄발생에 미치 는 영향을 보고자 하였다. 메탄발생에 영향을 미치는 인공습지의 수질 특성 중 수온이 가장 큰 영향인자였다. 광산지 역의 인공습지 7곳에서 폐쇄형 챔버법을 통해 측정한 메탄 flux는 -3.6~12.0 CH4 mg/m2/hr로 산정되었다. 유럽의 자유 수면 인공습지에서 산정된 메탄 flux와 유사한 범위를 보였다. 향후 광산지역의 인공습지에서 발생하는 메탄에 대해 연구하기 위해 기질의 특성과 그 기질을 이용하는 미생물, 환경조건 조절 등의 정량적인 메탄 발생 특성에 대한 연구가 필요하다.
Abstract
Global warming is accelerating due to methane release to the atmosphere. The contribution of mine areas among the anthropogenic sources of methane can not be ignored. However, the study on mine area as a methane source is insufficient. The purposes of this study are to monitor methane fluxes in constructed wetlands of mine areas and to investigate the effect of water quality on methane production. Water temperature was the most influential factor affecting methane emissions. The methane fluxes measured by a closed chamber method at aerobic wetlands were estimated to be -3.6~12.0 CH4 mg/m2/hr in seven mines in Korea. This range is similar to the methane flux estimated from European free water surface wetlands. As a future work, it is necessary to study the characteristics of the wetland substrates (or sediments), microbes using the substrates and their environmental control factors in order to qualitatively estimate the methane production in mine areas.
