Short-term exposure to sulfur dioxide can cause harm to the human respiratory system and make breathing difficult. People with asthma, particularly children, are sensitive to these effects of SO2.

Sulfur dioxide and other sulfur oxides also contribute to acid rain. They can react with other compounds in the atmosphere to form fine particles that reduce visibility, and stain and damage stone and other materials.

Elemental Instruments, a division of Ohio Lumex, offers a range of sulfur dioxide analyzers that provide online, real-time measurements to control and monitor emissions and processes.

Sulfur dioxide (SO2) is a toxic gas released naturally by volcanic activity. It is also produced as a by-product of copper extraction and the burning of fossil fuels contaminated with sulfur compounds, primarily for sulfuric acid manufacturers.

The largest source of SO2 in the atmosphere is the burning of fossil fuels by power plants and other industrial facilities. Smaller sources of SO2 emissions include industrial processes such as extracting metal from ore, natural sources such as volcanoes, locomotives, ships, and other vehicles and heavy equipment that burn fuel with high sulfur content.
