초록

온산공업단지는 인근에 울산석유화학단지가 위치해 있고 동쪽에는 바다가 위치하고 있는 공업지역이다. 이러한 이유로 온 산공업단지에서 배출되는 대기오염물질은 특히, 해풍과 같은 기상인자에 영향을 받기 쉽다. 본 연구에서는 기상자료를 분석하여 해풍과 박무발생 빈도를 평가하였으며, 온산공업단지 인근의 기상현상에 의해 영향을 받는 대기오염물질의 농도를 평가하기 위해 상층바람조건과 온위를 분석하였다. 분석결과, 박무와 해풍이 발생될 때, 미세먼지(PM10)는 각각 57.2%, 71.8%, 이산화황(SO2)은 46.6%, 57.7%로 고농도 현상이 나타났다. 이런 결과를 통해 박무와 해풍과 같은 기상현상이 대기오염물질의 고농도에 영향을 주는 것을 확인하였다. 온위와 상층바람조건을 활용한 상층기상을 분석한 결과, 해풍에 의한 울산석유 화학단지에서 배출된 대기오염물질의 이류가 온산공업단지 인근의 고농도 현상에 영향을 주는 것을 확인하였다. 특히, 안정한 대기조건에서 해풍이 발생했을 때, 온산공업단지의 평균농도에 비해 1.5배 이상 고농도 현상이 나타났다.

Onsan Industrial Complex located in a nearby the Ulsan Petrochemical Complex and in the east of the coast. For this reason, air pollution substances emitted by Onsan Industrial Complex especially tend to have an effect on meteorological factors such as sea breeze. In this study, we assessed the frequency of sea breeze and mist using the meteorological data, and analyzed potential temperature and upper wind condition for assessment of atmospheric pollution concentration influenced by meteorological phenomena in a nearby the Onsan industrial complex. From an analysis results, when mist and sea breeze happened, each higher concentration phenomenon of PM10 and SO2 appeared each 57.2%, 71.8% and 46.6%, 57.7% respectively. Hence, we confirmed that meteorological phenomena such as mist and sea breeze had an effect on high concentration of air pollution substances in the research area. Analytical result of meteorological data in upper layer using potential temperature and wind condition, we confirmed that advection of air pollution substances emitted in Ulsan Petrochemical Complex by sea breeze have an effect on high concentration in Onsan Industrial Complex and nearby the residential area. In particular, concentration in Onsan Industrial Complex were higher than the average concentration by a factor of more than over 1.5 times when sea breeze by stable condition in atmospheric layer appeared.
