Sources of sulfur dioxide pollution In 1963, more than 23 million tons of sulfur dioxide were discharged into the atmosphere of the United States. The fossil-fueled power plant is the chief contributor to sulfur dioxide emissions and accounts for over 40% of the total emission.
For example, coal burning power plants emit mercury (the highest source of mercury put into the air), home thermometers, button batteries, the new energy-saving fluorescent light bulbs, and seafood (shellfish, tuna, marlin and many others). Such items are all potential sources of mercury poisoning.
