In this paper, the emission processes of odors and VOCs sources for main industries were estimated thorough material balances and literature survey, and the characteristics of odors and VOCs concentration were examined by analysing four year of monitoring data in Jeonbuk Industrial Area. The several sampling sites were selected in the industrial site by considering TRI (Toxics Release Inventory), which were made by the Ministry of Environment based on the kinds and the amount of hazardous chemical materials for the industries, and the wind direction survey for ten years. Air samples were collected once per a season for four years in the sites. 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, acetone, formaldehyde, acetaldehyde, xylene, styrene and chloroform were detected as main volatile organic compounds in this area. Hydrogen sulfide, trimethylamine and acetaldehyde were main detected species the odorous compounds.
