Abstract
In this study, we examined the harmful substances of white smoke generated from steel manufacturing facilities and studied the influence of white smoke on the surrounding area using a gaussian model. As a results of analyzing white smoke, the concentration of TVOCs containing acetaldehyde 51.6 ㎍/㎥ was 829.3 ㎍/㎥. The TVOCs concentration of 823.9 ㎍/㎥ was lower than the indoor parking maintenance standard of 1,000 ㎍/㎥. However, the concentration was higher than the standard of 400 ㎍/㎥ for medical institution and nursery schools and the standard of 500 ㎍/㎥ for multiple facilities such as underground store. As a result of modeling, white smoke emitted from A steel spread to the southwest in the direction of mountain. As for the characteristics of the seasons, the same tendency is shown in spring and summer, but it was found that white smoke has a large area affected by the environment in spring. In autumn and winter, due to the influence of the northwesterly wind, the influence appeared mainly in the direction of G port wharf, which is south or southeast.
