SO2 is a gaseous pollutant that is emitted primarily by industrial furnaces or power plants burning coal or oil containing sulfur. At high concentrations, breathing can be impaired. Damage to vegetation can also result.
IDEM operates 10 continuous SO2 monitoring sites that are polled hourly in order to obtain the most current information. This continuous data is available interactively by clicking on the map or the table below.
Continuous data is available online now - please click on the links below to access this information. Intermittent data is not available at this time but will be coming soon!
