Abstract

This study was carried out to characterize the ambient VOCs concentrations of industrial complex in Daegu city. VOCs concentrations of industrial complex area appeared to be higher than those in the non-industrial complex area as following order toluene > ethylbenzene > m,p-xylenes > o-xylene but benzene and chloroform were similar to each other sites. There was seasonal variation of VOCs concentrations in the industrial complex area, higher in summer and lower in winter. In particular the industrial complex area shows that higher on weekday than weekend and higher in the daytime than in the morning or nighttime because industrial complex area influenced by the chemicals. Correlation coefficients among VOCs were confirmed that VOCs of industrial complex area were more related to each other than those of non-industrial complex area and VOCs concentrations have shown generally negative correlation with wind speed.

본 연구는 대구광역시 산단지역 대기 중의 휘발성유기화합물 특성을 조사하였다. 산단지역은 비산단지역에 비해 톨루엔, 에틸벤젠, m,p-자일렌, o-자일렌 순으로 높은 농도차를 보였고, 벤젠과 클로로포름은 지역별로 뚜렷한 농도차가 없었다. 측정계절별로는 산단지역은 하고동저형을 보였다. 특히 화학물질 사용 영향으로 인해 산단지역은 측정요일별로는 평일이 휴일에 비해 높게 나타났고, 측정시간대별로는 가동시간을 포함한 오전, 오후 시간대가 상대적으로 높게 나타났다. VOCs 물질간의 상관성은 산단지역이 비산단지역에 비해 유의한 상관이 많았고, 기상인자와는 풍속이 VOCs와 음의 상관을 보였다.
