The chemical formula Sulphur dioxide is SO2. Sulphur in sulphur dioxide is sp2 hybridised. Ideally, the bond angle should be 120o but the O–S–O bond angle is found to be 119o. This happens due to the lone pair of electrons on the Sulphur atom. The lone pair-bond pair repulsion decreases the bond angle from 120o to 119o.

Exposure to sulfur dioxide occurs from breathing it in the air. It affects the lungs and at high levels may result in burning of the nose and throat, breathing difficulties, and severe airway obstructions. This chemical has been found in at least 16 of 1,467 National Priorities List sites identified by the Environmental Protection Agency (EPA).

The penetration of sulfur dioxide to the lungs is greater during mouth breathing than during nose breathing. Sulfur dioxide is readily removed during passage through the upper respiratory tract. At concentrations higher than 1 ppm, removal is over 90% (Strandberg, 1964). Sulfur dioxide is converted to bisulfite ion (HSO 3 ¯) on
