春川地域의 大氣中 SO₂ 및 TSP灌度에 관한 調査硏究

A Study on Atmospheric Concentrations of SO₂ and TSP in Chuncheon Area

The atmospheric concentrations of Sulfur Dioxide and Total Suspended Particulates were measured in Chuncheon and Wonju from August 5 to October 20, 1989. The results of the study are as follows. 1. The atmospheric concentrations of S02 were 0.014 ppm and 0.030 ppm ín Chuncheon and Wonju, respectively, πle highest concentration was 0,044ppm ín the commercial area of Wonju city. 2. The variation of S02 concentration by time of the day showed a tendency that levels in the morning and evening were higher than those in the afternoon. Temperature inversion was observed at dawn, The highest concentration, 0.055ppm, was recorded at Hupyung lndustrial Complex in the afternoon. 3. The TSP levels by sampling locations were as folJows. Hupyung lndustrial Complex inclicated 257μ:g/m3， H upyungdong 94μg/m3， Chungangro 145μ:g/m3, Saembat 60μg/m3 ín Chuncheon, and Wonju lndsutrial Complex 130μ:g/m3， J ungangdong 147μ:g/m3’ Gaewoondong 107μ:g/m3 in Wonju, 4. The TSP concentratíon by sampling time showed that the highest was at the time of O~ : 애~ 16: ()(), the lowest at ()() : ()()-08 : 00. 5. The S02 concentrations under foggy conclition were lower than those under no fog.
