In this study, the characteristic of BFM was studied wherein nonlinearity was shown in the relation between ship emissions and PM<SUB>2.5</SUB> concentrations. The study was varied the cargo ship emissions reduction from 100%, 70%, and 50%, to 30% to review uncertainties and estimate the range of contributions for the simulated results and sensitivity analysis was conducted for each component. As a result, nonlinear characteristics were found for change in the ship emissions and, accordingly, for change in the PM<SUB>2.5</SUB> levels. However the coefficient of quadratic terms was small enough and there was not a significant curved pattern change for the ship sources. The components, excluding those that include EC and mineral particles, are chemical species that have a range of chemical reactions in the atmosphere to lead the secondary formation of PM<SUB>2.5</SUB>. Therefore, although the pollutant emissions from ships decreased the same rate, the simulated levels showed a nonlinear tendency. For the episode period, the contribution of ships was analyzed for each of the conditions for ship emissions sensitivity experiments. As a result, for Sinheung, which is located closest to the port, the contributions ranged from 4.3 to 4.8 μg/㎥; following this, the range was from 2.8 to 3.1 μg/㎥ for Songnim, and from 0.9 to 1.2 μg/㎥ for Bupyeong.
