In order to investigate the characteristics of the effects of various emission sources such as ships around the Busan North Port area, PM<sub>2.5</sub> samples were analyzed by SEM/EDS (scanning electron microscopy with energy dispersive x-ray spectrometer). In the port city Busan, the main emission source of PM<sub>2.5</sub> is ships, and soot was observed as the main exhaust particles of a ship diesel engine. As a result of the individual particle analysis of PM<sub>2.5</sub> at the sampling site, carbonaceous particles such as soot and water droplet-shaped, which are considered to be exhausted from ships, were constantly observed. And some spherical Fe-rich particles also appeared.
