 Abstract
In this study CALPUFF modeling was performed to establish a correlation between regions of frequent civil odor complaints near Gumi national industrial complex and odor-emission facilities of synthetic fiber manufacturers in the same area as main acetaldehyde-emission point sources. As a result of the CALPUFF modeling, the maximum concentration of acetaldehyde in Gumi national industrial complex was reduced from O () to O () upon improving emission facilities of T company so that the maximum concentrations of acetaldehyde frequently appeared in complex 3. In addition, the predicted range of the maximum acetaldehyde concentration in Gumi national industrial complex was also improved in comparison with that prior to improving emission facilities of T company. These maximum concentrations of acetaldehyde obtained to estimate the expected contribution of total acetaldehyde point source by CALPUFF modeling showed the similar values to those measured in `HAPs investigation in the region of Gumi-Daegu` and were consistent to the trend of civil odor complaints. Therefore, the expected contribution of total acetaldehyde point source was validated. The relative contribution of T company upon improving its emission facilities was predicted to be lowered by more than factor of two, compared to that prior to improving its emission facilities. To the contrary, the relative contribution of W company upon improving emission facilities of T company was predicted to be increased by more than factor of two, compared to that prior to improving emission facilities of T company. This indicates that the contribution of aldehyde point sources of W company was relatively increased upon improving emission facilities of T company.
