  • Sulfur Dioxide Basics | Sulfur Dioxide (SO2) Pollution

    SO 2 emissions that lead to high concentrations of SO 2 in the air generally also lead to the formation of other sulfur oxides (SO x).). SO x can react with other compounds in the atmosphere to form small particles. These particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs and in sufficient quantity can contribute to health problems.
