Outdoor Air:
Sulfur Dioxide (SO2)
The burning of coal and oil (from electric utilities and industrial fuel combustion) produces sulfur
dioxide. Like the nitrogen oxides, sulfur dioxide can change forms in the
atmosphere, contributing to acid rain (as sulfuric acid) and to ultra fine
particulate matter levels as sulfates and sulfites. Additionally, sulfur
combines readily with ammonia to form ammonium sulfate, one of the most
significant components of PM2.5 pollution in Houston.
Why is sulfur dioxide bad?
Exposure to sulfur dioxide and its various forms have been linked to:
- difficulty breathing;
- lowered resistance to infection; and
- increased cardiovascular
incidents including heart attacks.
