Abstract

이 연구에서 환원성 황 화합물의 시간적, 공간적 분포 패턴들이 매립과정에 크게 영향 받는 지역에서 조사되었다. 이러한 측정 연구에 기초하여 환원성 황 화합물이 이산화황으로 변환되는 광화학적 작용 규모를 광화학적 상자모델을 이용하여 평가하였다 이 연구는 2004년 3월에서 12월까지 대기 중 환원성 황 화합물 농도를 군산시의 매립장 내부와 인근에서 평가했다. 환원성 황 화합물의 분포가 일반적으로 $H_2S$, DMS, 또는 DMDS들이 대부분인 반해, 그 패턴들은 시료채취 지역과 기간에 따라 다양했다. 군산 매립장에서 $H_2S$, DMS는 연구기간 동안 가장 높은 농도를 나타냈다. 이 지점에서 DMS의 농도는 매립 과정 뿐만 아니라 해양 오염원에 영향을 받는다고 사료되었다. 모든 환원성 황 화합물이 아황산가스의 광화학적 부산물에 대한 상대적 기여도를 비교할 때, 세가지 환원성 황 화합물(DMDS, $H_2S$, 그리고 DMS)이 가장 중요한 물질로 조사되었다.
