The objectives of this study were to investigate the seasonal characteristics of metallic and ion elements of PM10(Particulate matter with aerodynamic diameter ≤10 ㎛) and the effects of vessels exhaust emission from ships harboring in Busan City. The PM10 samples were collected from January 2010 to October 2010 at Dongsam-dong(coastal area), in Busan City. The particulate matters were analyzed for major water soluble ionic components and metals. The ranges of the PM10 mass concentrations were from 29.8 ㎍/㎥ to 47.0 ㎍/㎥ in Dongsam-dong. The PM10 mass concentrations in Dongsam-dong are very similar to Gwangbok-dong during same sampling periods. These results were understood by the effects of the shipping source emitted from ships anchoraging and running. The concentrations of water-soluble ions and metals in the PM10 had a level of as high as the order of SO42->NO3->Cl- and NH4+>Na+>Ca2+>K+>Mg2+, respectively. The correlation coefficients(R2) for SO42-/PM10 and NH4+/PM10 of were 0.7446 and 0.7784, respectively, and it showed the high correlation with each other.
