The purpose of this experimental study is to investigate seasonal deposition flux variations and deposition velocities of the total dusfall and various inorganic elements in it. Total 41 dustfall and TSP samples were collected from November, 1997 through December, 1998 in Kunsan. Each sample was analyzed by and AAS to determine he levels of 5 inorganic elements: Zn, Cd, Cr, Fe and Pb. Deposition fluxes, soluble/total fractions and deposition velocities for each element were extensively investigated. Estimated dry deposition fluxes of dustfall and elements in Kunsan were in the range of 14.6~48.8(mean 25.6) ton/$ extrm{km}^2$/yr for dustfall, 14.5~72.6(mean 44.1)kg/$ extrm{km}^2$/yr for Zn, 0.9~0.5(mean 3.0) kg/$ extrm{km}^2$/yr for Cd, 2.1~239.2(mean 63.9) kg/$ extrm{km}^2$/yr for Cr, 331.6~1,082.7(mean 873.9) kg/$ extrm{km}^2$/yr for Fe, 5.2~178.4(mean 49.2) kg/$ extrm{km}^2$/yr for Pb, respectively. And the concentra-tion of TSP and elements in Kunsan were 71$mu extrm{g}$/㎥ for TSP, 29.9ng/㎥ for Zn, 0.6ng/㎥ for Cd, 0.1 ng/㎥ for Cr, 1,061.0 ng/㎥ for Fe, 4.0 ng/㎥ for Pb, respectively. And the estimated deposition velocity of dustfall and elements in Kunsan were 1.13$ imes$ 10(sup)-2 cm/sec for dustfall, 4.67$ imes$ 10(sup)-2 cm/sec for Zn, 16.92 cm/sec for Cd, 15.69 cm/sec for Cr, 1.72$ imes$ 10(sup)-2 cm/sec for Fe, 0.36 cm/sec for Pb, respectively
