This study focuses on the assessment of long-term So_(2) concentration around the Yochon industrial complex area using ISCLT model. ISCLT model has been officially authorized by the U.S. EPA. Yochon industrial complex was located around Kwang-yang bay. In order to simulate the prediction of long-term So_(2) concentration by ISCLT model and the application in Yochon industrial complex area, every point source was identified and applicability to this region was studied in detail. Long-term meteorological data were analyzed from 1995 to 1998. As the result of verification and calibration for the model accuracy. the conversion factor was 8.35. According to the analysis from 1995 to 1988 meteorological data in Yochon, west north west(WNW: 13), north east north(NEN: 1), and south(s: 8) direction were identified to be the most frequently occurred one whit its frequency. As the result of modeling prediction, SO_(2) concentration in Yochon petroleum industrial complex area was satisfied to Air Quality Standards.

The odor of sulfur compounds which are of air pollutants in petroleum industrial complex was investigated. Concentration vs. peak areas resulted from analyzing four sulfur compounds within the ranges of very low concentration by GC method were correlated. Correlation coefficients of four sulfur compounds were found to be above 0.9941 and very good. No sulfur compounds exception hydrogen sulfide(H₂S) were detected at four measuring sites. Also, concentration of hydrogen sulfide was much lower than an emission standard(0.2ppm) within the industrial area. Concentration of hydrogen sulfide was insignificantly changed with times and sites of sampling. However, average concentration of hydrogen sulfide of #2 site was higher than other sites.
