Indiana Department of Environmental Management

Air Toxics Program

IDEM Air Toxics > About About

Air toxics are pollutants known to cause cancer and other serious health impacts. The Indiana Department of Environmental Management (IDEM) tracks these pollutants with a series of air toxics monitors located in primarily urban areas of Indiana. IDEM analyzes this data to determine if any significant problems related to air toxics exist within the state, and to determine if air toxics concentrations are increasing or decreasing. This analysis enables IDEM’s Air Toxics Program to assess the risk posed to public health and develop programs to protect the quality of our air.

The Air Toxics Program site can connect you with more information on how IDEM manages toxic pollutants through the use of Modeling, Monitoring, and Risk Assessment. Knowledge of these topics will help you understand what is in the air you breathe, how to assess the risk posed by toxic pollutants, and how IDEM works to protect public health. IDEM’s Hazardous Air Pollutant (HAP) Emissions Inventory serves to track increases and decreases in air toxics and provide a building block for modeling studies. Analysis of past monitoring data, and real time data from IDEM’s Photochemical Assessment Monitoring Stations (PAMS), is available to the public on the Air Toxics Monitoring Data page. IDEM has also conducted several in depth studies of air toxics and their effects on the health of Hoosiers in high-risk communities. These studies can be found on the Air Toxic Studies page.

Thank you for your interest in learning more about these important issues. Please contact IDEM’s air toxic experts if we can assist you with any additional questions.
