Question

Quizplus · Accepted Answer

Coal-fired electric generators are the primary source of sulfur oxide pollution. When coal is burned, it releases sulfur dioxide into the air, which can then react with other compounds to form sulfuric acid and other harmful pollutants. Automobile exhaust, chemical manufacturing, and nuclear power plants can also contribute to sulfur oxide pollution, but to a lesser extent than coal-fired electric generators.
