The atmospheric S02 concentrations and water soluble sulfur contents in Ginkgo biloba were measured and analyzed in auto-measuring station, Kwangleung, and Yongmun from August 5 to Oct。ber 21, 1990. The results of the study are as follows : 1. Atmospheric S02 concentrations between the seoul area(Pulkwang, Ssangmun, Myonmok, Gilum) in which the concentrations exceeded the air quality standards and the surburb of seoul( Kwangleung, Yongmun) revealed the significant difference(p<O.OI). 2. Water soluble sulfur contents in Ginkgo biloba in autumn were higher than those in Ginkgo biloba in summer( p<O.01). \Vater soluble sulfur contents in leaves showed a significant difference between seoul and its surburb(p<O.Ol). 3. Correlation between atmospheric S02 concentration and water soluble sulfur content of Giηo biloba in autumn was as follow : Y=0.2714+9.8123 X, r=0.6362 (X: Airborne S02 Concentration according to sampling 10 cation, Y : Water Soluble Sulfur Contents)
