The purpose of this study was to investigate spatial distributions of total deposition. A total number 79 samples were collected at 17 sampling sites from September 1999 to January 2000. Total (=wet+dry) atmospheric depositions were collected by filtered deposition sampler at sampling site (the Western Part of Kyongsangnam Province). In addition, the deposition of soluble and insoluble fraction was also investigated to find a suitable simplified collection method for a long-term monitoring of total deposition. The total depositions were measured soluble amount(mm/month), insoluble amount(kg/km/month), pH, conductivity(E.C.) and eight ionic components. The spatial distribution of deposition flux was to estimated by using a kringing analysis. The 17 sites mean fluxes of water soluble ionic components; SO2-/, Cl-/, NO-/, Na+/, NH+/, K+/, Mg2+/, Ca2+/ were 100.7∼315.6kg/km/month, 30.1∼234.3kg/km/month, 64.4∼ 139.4kg/km/month, 7.5∼68.3kg/km/month, 10.7∼48.7kg/km/month, 5.6∼27.9kg/km/month, 4.5∼17.5kg/km/month, 27.6∼81.7kg/km/month, respectively.
