Sulfur Dioxide (SO2)


Air Villain: Brimstone Bertha


Status: Busted

Description: (Compound) Sulfur dioxide is a colorless gas with a pungent odor and taste.

Crime: SO2 causes irritation and permanent damage to the lungs. SO2 can be transported over long distances. It contributes to the formation of acid rain, which damages plant and animal life, buildings and electrical equipment. Inhalable sulfate particulate matter formed from SO2 can impair visibility. Further reductions of SO2 emissions are necessary.

Cause: SO2 emissions result from oil refineries, the burning of fossil fuels at power plants and in boilers.
