In this study, we focused on the geographical and the meterological conditions, the atmospheric examination, the soil contents and compositions in order to establish cultural properties conservation plan in Gyeongju and its surroundings. Also, the transport route with environmental contaminants in Ulsan and Pohang was examined. The results could be summarized as follows ; Air pollutant and environmental contaminant was transported by two types of winds. One is induced by local winds, the other is induced by synoptic winds. Air contaminant transported from coastal regions to inland regions were associated with wind velocity. Gyeongju had good atmospheric conditions, i.e. $SO_2;0.009{sim}0.011ppm,;CO;0.6{sim}0.8ppm,;NO_2;0.015{sim}0.020ppm,;O_3;0.017{sim}0.032ppm,;PM_{10};46{sim}62{mu}g/m^3;and;Pb;0.034{sim}0.060{mu}g/m^3$, which was below environmental air qualify standards and was little lower than those of Pohang and Ulsan. However, Ulsan and Pohang city are located on south-east coast and have many industrial facilities. Hence, air pollution problems become serious issues in Ulsan, Pohang, Busan, Daegu and other cities due to the emission of air pollutants from the various industrial facilities, incinerator and power plants, etc. The soil of Gyeongju had heavy metals conditions, i.e. $Cd;0.01{sim}0.08mg/kg,;Cu;N.D{sim}2.39mg/kg,;As;N.D{sim}0.07mg/kg,;Hg;N.D{sim}0.15mg/kg,;Pb;0.49{sim}1.39mg/kg,;Cr^{+6};0.02{sim}0.42mg/kg,;Fe;0.74{sim}1.55mg/kg,;Mn;0.11{sim}0.49mg/kg;and;Zn;1.11{sim}3.56mg/kg$. However, pH value of soil had range of $4.12{sim}7.45$. The results showed that high pH concentration of soil could occur due to air pollution diffusion and environmental contaminant transport at Ulsan and Pohang city.
