To properly manage and remediate groundwater contaminated with chlorinated hydrocarbons such as trichloroethylene (TCE), it is necessary to assess natural attenuation processes of contaminants in the aquifer along with investigation of contamination history and aquifer characterization. This study e...

트리클로로에틸렌(trichloroethylene; TCE)을 포함한 염소계 유기화합물의 특징은 무엇인가? | 트리클로로에틸렌(trichloroethylene; TCE)을 포함한 염소계 유기화합물은 가장 대표적인 지하수 내 유기오염물로서(Sterling et al., 2005; Damagaard et al., 2013; Wanner et al., 2016), 국내에서도 산업단지를 중심으로 빈번하게 이로 인한 지하수 오염이 보고되고 있다(Baek and Lee, 2011; Yang and Lee, 2012; Lee et al., 2015). | |
탈염소화 작용으로 TCE가 분해되는 경로는 무엇인가? | 한편 자연상태에서 이들을 분해할 수 있는 미생물들이 있을 때에는 생분해될 수도 있는데 혐기성 환경에서 탈염 소화 작용에 의한 반응이 가장 중요한 것으로 알려져 있다(US EPA, 1998). 탈염소화 작용이 일어날 때 TCE는염소가 제거됨에 따라 TCE → 시스-1,2-디클로로에텐(cis-1,2-dichloroethene; cis-1,2-DCE) → 비닐 클로라이드(vinyl chloride; VC) → 에텐(ethene)/에탄(ethane)의 경로로 분해된다. 또한 호기성 환경에서는 공대사(cometabolism)로분해되기도 하나 주된 반응은 환원적 탈염소화(reductive dechlorination)로 알려져 있다(Maym-Gatell et al. | |
TCE가 호기성 환경에서 분해되는 반응은 무엇인가? | 탈염소화 작용이 일어날 때 TCE는염소가 제거됨에 따라 TCE → 시스-1,2-디클로로에텐(cis-1,2-dichloroethene; cis-1,2-DCE) → 비닐 클로라이드(vinyl chloride; VC) → 에텐(ethene)/에탄(ethane)의 경로로 분해된다. 또한 호기성 환경에서는 공대사(cometabolism)로분해되기도 하나 주된 반응은 환원적 탈염소화(reductive dechlorination)로 알려져 있다(Maym-Gatell et al., 1997; Chu et al. |
