摘要：Sulfur dioxide and fall dust in the air were collected from January 12 to February 3, 1974, at Syowa Station. The analysis showed that concentration of sulfur dioxide was from 1 to 30μg/day/100 cm^2 PbO_2. The concentration of sulfur dioxide depended on wind direction and velocity, and high concentration was observed in the area between the station building and 300 m southwest of the station, but other sampling points showed low concentration nearly equal to the background value. The concentration of fall dust was from 0.2 to 3.0 g/m^2/month, but it was independent of wind direction and wind velocity.
