Sulfur dioxide and fall dust during summer season at Syowa Statin, Antarctica

Abstract

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.
