Sulfur dioxide - Exposure Summary

Sulfur dioxide is released to the air from volcanic activity and eruptions. If released to air, a vapor pressure of 3.0X10+3 mm Hg at 25 deg C indicates sulfur dioxide will exist solely as a gas in the atmosphere. Gas-phase sulfur dioxide is oxidized rapidly by homogeneous and heterogeneous reactions. The oxidation of sulfur dioxide to sulfuric ...
