Study on dustfall characteristics and dry deposition velocity in Kunsan

In this study, we obtained 94 dustfall samples from September, 1997 through August, 1999 in Kunsan. To collect dustfall samples, British deposit gauges were set at three different sites which were representitive sites of industrial, commercial and residental area in Kunsan, and then dustfall flux was calculated with analysis of metallic elements such as ln, Cd, Cr, Pb and Fe. From this result, apparant difference of regional and seasonal fluxes were observed. That is, the areal fluxes were that dustfaJl, Fe, and Cd were highest at commercial site, but Pb, ln and Cr were highest at industrial site and the seasonal flux was that ln, Cr and Fe were very high value during spring, 1998 (Yellow sand period), And estimated mean dry deposition velocity of dustfall and metallic elements were 0.0168 ㎝/see for dustfall, 0.0680cm/sec for ln, 0.3230㎝/sec for Cd, 1.8222 ㎝/see for Cr, 0.7822 em/see for Pb, 0.0210 for Fe, respectively.
