Abstract

In this study, the AERMOD air diffusing model was used to estimate the range of influence of Hazardous chemicals (hydrogen fluoride) in case of small accidents in Jeju area. The impact scope were in the order of Seogwipo Fire Station, Dongbu Fire Station, Jeju Fire Station, and Seobu Fire Station. Seasonal orders were summer, spring, autumn and winter. The correlation between the meteorological factors shows a strong positive correlation with the wind speed of 0.998 and has a negative correlation with the temperature of -0.463. Through the linear regression analysis, we could estimate the equation of Impact scope = 13.922WS (Wind Speed) - 5.195 and the reliability ($R^2$) was as high as 0.995.

본 연구에서는 AERMOD 대기확산 모델을 이용하여 제주도에서 유해화학물질 중 불화수소의 소규모 유출사고 영향 범위를 산정하여 보다 빠르고 정확한 대응시스템을 확보하고자 하였다. 분석결과 영향범위는 권역별로 서귀포소방서, 동부소방서, 제주소방서, 서부소방서 순으로 넓게 나타났으며, 계절별로는 여름, 봄, 가을, 겨울 순으로 넓게 나타났다. 기상인자(풍속, 기온) 간의 상관성은 풍속이 0.998로 높은 양(+)의 상관성을 보인반면, 기온과는 -0.463으로 음(-)의 상관성을 보였다. 선형회귀분석을 통해 불화수소 누출사고 시 풍속에 따른 영향범위(m) = 13.922WS(풍속) - 5.195의 1차 방정식을 얻을 수 있었으며, 신뢰도($R^2$)가 0.995로 매우 높게 나타났다.
