This study was performed to figure out the characteristics of concentration and profile pattern of Unintentional Persistent Organic Pollutants(UPOPs; PCDD/DFs, DLPCBs, HxCB) in the ambient air, atmospheric deposition and soil in Ulsan area. The correlation among the concentration of the ambient UPOPs, depositing velocity, flux and other meteorological factors was examined during the ambient process of the UPOPs. Furthermore, deposition flux from the ambient to the surface was calculated to estimate the contribution of deposition to soil pollution. The result shows that the annual deposition flux from the ambient to the soil in Ulsan was 4.6 ng WHO-TEQ/m2/year, 3.3ng WHO-TEQ/m2/year and 0.2ng van Birgelen98-TEQ /m2/year, respectively. The total amount of UPOPs fluxing into the ground from the ambient air was estimated as 10.9 g TEQ/year. In this study, deposition flux value of TEQ exceeds the European guideline or limit. The profile patterns of UPOPs in the ambient-deposition-soil were similar. From the study, the importance of the soil pollution by the deposition through the atmospheric process of pollutants exhausted from the sources was proved.
