  • Why Measure for Sulfur Dioxide (SO2) in Homes Offices | E

    Sulfur Dioxide (SO 2) is a highly reactive gas that is part of a larger group of sulfur oxides or SOx gases.According to the U.S. Environmental Protection Agency, the largest sources of SO 2 emissions are due to “fossil fuel combustion at power plants (73%) and other industrial facilities (20%)”.
