 note = {Large amounts of SO2, emitted by combustion of coal in China, are affecting the environment inside and outside China. In order to estimate this influence, it is necessary to estimate the quantity of SO2 removed by dry deposition on Chinese loess. In order to measure the dry deposition of SO2, we proposed the use of a passive sampling medium. The samplers were prepared by evenly distributing soil in a Petri dish and exposed it to SO2 and, after a given exposure period, the deposited SO2 was quantified by extraction and further IC analysis. However, we found that this medium had the problem of soil sample loss by the wind. To solve this problem, we propose the use of a new collection medium, consisting of soil tablets prepared by pressing a mixture of soil sample and Teflon powder to form the tablet. In this study, the feasibility of the use of tablets was investigated using native soil collected from the loess plateau in Lanzhou, China. The influence of the application of Teflon powder and the difference of molding pressure when making the tablet over dry deposition of SO2 was not found; and it was confirmed that at different concentration, there are no affect on the deposition velocity. Therefore we conclude that the use of tablets is feasible., 指導教員: 埼玉大学大学院理工学研究科教授 坂本和彦, text, application/pdf},
