摘要：
The amount of dry deposition of SO2(g) and HNO3(g) in an urban area in Japan has been estimated by the inferential method. The mean annual dry deposition of SO2(g) (2.91 kgS/ha/year) was close to or less than that in the Clean Air Status and Trends Network (CASTNet) of the U.S. (3.59 kgS/ha/year). The mean annual dry deposition of HNO3 (9) (10.8 kgN/ha/year) was approximately six times larger than that in CASTNet (1.85 kgN/ha/year). The proportions of dry/(dry+wet) deposition for sulfur and nitrogen were 0.301 and 0.785, respectively.
