완주지역의 악취물질 및 VOCs의 배줄 특성 연구
Abstract
In this study VOCs and odors in ambient air of the Wanju industrial site and a regional area were measured to build up a data base and predict the effect of them on the ambient air quality of the near regional area. Emission characteristics were examined by measuring odors and VOCs from the main emission sources sorted by the categories of industries. Three emission points were selected for odors and five points were for VOCs. VOCs in ambient airs of the industrial site and outside regional area toward the wind direction were also measured continuously during three days per a season for a year and the effect of the VOCs emitted from the industrial sites on the ambient air of the near regional area were evaluated. GC-PFPD, HPLC, and GC-FID were used for measuring sulfur compounds, aldehyde, and trimethylamine among odorous compounds and GC-MSD was used for VOCs. As the main results of this study, toluene, benzene, xylene, styrene, ethyl benzene, 1,3,5-trimethylbenzene and 1,2,4-trimethylbenzene were detected as main volatile organic compounds in this area. Hydrogen sulfide, trimethylamine and acetaldehyde were main detected species the odorous compounds.
