In order to investigate the characteristics of dustfall at eight sites in Pusan, the dustfal1 samples were collected with dust jar method from May to September 1995, and Cr, Mn, Fe, Ni, Cu, Zn, Cd and Pb were analyzed, The main results of this study are summarized as follows; 1) The total mean value of dustfall was 11.30 ton//month. 2) The maximum and minimum values of dustfall were industrial and resident area respectively, 3) The dustfall showed the general trend in order as May>Jun>September>July. 4) The general trend of the heavymetals in dustfall was in order as Fe>Cu>Zn>Pb>Ni>Cd>Cr>Mn any the concentrations of heavymetals had different tendencies according to sources of Pollutant meterials. 5) The Concentrations of Fe, Cu, Pb, Ni, Cd and Cr in industrial area and Mn, Pb and Zn in traffic area were high. The concentrations of heavymetals in residence area and unpolluted area were generally low. 6) Cr, Cu and Cd were influenced by the steel industry and the metal products plant and Zn was influenced by the automobiles. Mn, Fe and Ni were influenced by the soil as wet as artificial outlet. 7) The correlation between the total amount of dustfall and the concentrations of the heavymetals by month was high and the correlation between the heavymetals of the same origin was high.
