| 염소계 유기용매에는 어떤 것들이 있는가? | 테트라클로로에틸렌(tetrachloroethylene, PCE), 트리클로 로에틸 (trichloroethylene, TCE) 및 트리클로로에탄(trichloroethane, TCA)과 같은 염소계 유기용매(chlorinated solvent)는 다양한 산업분야에서 사용되고 있다. 그러나 1960년대까지는 이들의 위해성에 대해서 밝혀지지 않아 이들에 대한 관리가 체계적으로 이루어지지 않았다가 1975년 미국 국립암연구소(National Cancer Institute)가 PCE와 TCE를 암을 유발시킬 수 있는 의심물질(suspect human carcinogens)로 보고하였다. | |
| 가스크로마토그래프를 이용한 TCE의 탄소 동위원소 조성 분석방법을 설명하세요. | TCE의 탄소 동위원소 조성 분석방법은 다음과 같다. 퍼지앤트랩(purge and trap) 시스템을 이용하여 채취한 시료로부터 TCE를 추출한 후 가스크로마토그래프(gas chromatograph, GC)를 이용하여 순수한 TCE를 분리한다. 분리된 TCE는 약 800-940℃의 전기로에서 연소하여 CO2로 변환하고 변환된 CO2는 IRMS를 이용하여 탄소 동위원소 조성을 분석한다(Zwank, 2004). GCIRMS의 분석오차는 0. | |
| 토양에 비해 지하수에서 오염 물질에 관해 알기 어려운 이유는? | 국외뿐만 아니라 국내에서도 토양과 지하수 오염지역의 오염조사 및 복원에 대한 의무가 오염원인자에게 있기 때문에 오염원인 및 오염물질의 이동을 밝히는 것이 매우 중요하게 되었다. 특히 토양에 비해서 지하수에서는 오염 물질이 지하수의 유동방향에 따라서 이동하기 때문에 오염의 원인 및 오염물질의 이동에 관한 정보를 얻는 것이 매우 어렵다. 최근까지 국내에서도 TCE로 오염된 지하수에 대한 연구가 활발하게 진행되었으며(Kim et al. |
