Abstract

유해물질의 거동에 대한 이해를 돕기 위해서 대도시지역을 대상으로 하여 fugacity를 이용한 level-III 다매체환경거동모형이 개발되었다. 이 모형에 의한 거동의 예측결과에 민감한 영향을 주는 입력과정과 변수들을 찾아내기 위하여 체계적으로 민감도분석을 수행할 수 있도록 하는 기법을 개발하고 사례연구로서 서울지역과 2, 3, 7, 8-TCDD을 대상으로 그 기법을 적용하였다. Sensitivity index에 의한 평가한 결과, 일정한 배출속도조건에서는 대기중의 바람속도, 그리고 대기에서 수체나 토양으로 전이되는 건식 및 습식 침적과정이 다매체거동에서 전체적으로 가장 중요한 과정인 것으로 나타났다. 또한 이들 거동과정 자체에 영향을 미치는 변수들에 대한 민감도 분석의 결과 건식침적의 경우 중력에 의한 입자들의 침강속도가, 습식침적의 경우 평균 강우속도가 대단히 중요한 변수임이 파악되었다. 물질의 물리화학적 특성 가운데에서는 z-값에 직접 영향을 주는 변수들, 즉, 헨리상수와 옥타놀-물 분배계수 등이 결과에 민감한 영향을 주는 것으로 나타났다. 이러한 사례연구는 본 연구에서 개발된 민감도분석기법이 유해물질의 다매체 거동모형을 개선하고 좀더 중요한 거동과정에 대한 이해를 넓히는데 효율적으로 사용될 수 있다는 것을 보여주고 있다.
