Asthma, COPD, allergies, lung cancer, cardiac, high blood pressure, diabetes, and other chronic conditions can all be affected by air quality. The Missouri Department of Natural Resources operates air instruments that collect data to determine:

  • whether an area meets the National Ambient Air Quality Standards.
  • whether the public is being exposed to unhealthy conditions.
  • to identify air pollution trends.
  • to investigate citizen complaints.
  • to determine the source of air pollution problems.
More information is available from the Missouri Department of Natural Resources’ Air Quality program, or by contacting the Department of Health and Senior Service's Bureau of Environmental Epidemiology, at (573) 751-6102.
