권수한,김광렬,황태모 충북대학교 건설기술연구소 1991 建設技術論文集 Vol.9 No.2
This study was carried out to investigate on air pollution at Cheong ju city, so the values of pH of the rainfall, amounts of dustfall and total suspended particulates, concentrations of sulfur oxide, and heavy metals in the suspended particulates were analyzed from march 1990 to march 1991. The results were as follows ; 1. The mean value of pH in the rainfall was 6.01, and the range of pH values was 5.04∼7.03 2. The mean value of dustfall was 17.3 ton/㎢/30days, and the range of that was 12.4∼21.0 ton/㎢/30days 3. The mean concentration of sulfur oxide was 0.71mg SO₃/day/100㎠ PbO₂, and the range of that was 0.22∼1.24mgSO₃/day/100㎠ PbO₂. 4. The mean value of total suspended particulates was 155.0㎍/㎡ and this value was higher than pollution index, The range of TSP was 88.8∼198.1㎍/㎡ 5. The mean values of heavy metals of TSP were 0.002㎍/㎡ of Cd, 0.17㎍/㎡ of Pb, 0.037㎍/㎡ of Cu, 0.136㎍/㎡ of Zn and 0.045㎍/㎡ of Mn, respectively.
