In this study, we investigated the emission concentrations of 31 odorous compounds from various emission sources of 37 individual companies located within the Ban Wal industrial complex of Ansan city, Korea. In the course of our study, we attempted to evaluate emission characteristics of different industrial activities and relative significance of different odorous components . Based on our measurements of odorous compounds, we were able to find a line of evidence to draw a conclusion that a number of odorous compounds can be used as indices to specifically point out the influence of certain industrial activities. It was found that hydrogen sulfide and trimethyl amine record the highest contribution from leather industry. Likewise, acetaldehyde showed its maximum contribution from food-beverage sector, while ammonia for paper-mill, pulp production sector. On the other hand, the results of styrene and most YOC including BTEX were not useful, as their concentrations were not significantly high enough to judge from such respect.
