How do I report my concern with a chemical exposure? - EH: Minnesota Department of Health

Reporting Concerns:
What can I do if I am worried about a chemical exposure?

MDH can assist the public with health-related questions about environmental exposures.

  • Environmental health scientists in the Site Assessment and Consultation Unit (SAC) can provide information about how chemical exposures affect your health and possibilities for controlling or preventing exposures that might be harmful.
  • SAC staff can also help you find resources for more information or determine if your situation needs to be investigated by an agency that has regulatory authority. These agencies include the Minnesota Pollution Control Agency (MPCA), the Minnesota Department of Agriculture (MDA), the Environmental Protection Agency (EPA), and some local governmental offices.
  • SAC also responds to requests from doctors and other health care workers. Health professionals can contact SAC scientists directly with questions regarding chemical exposures and the potential health effects. We can provide assistance with how to identify patients’ chemical exposures and suggestions about preventative measures.

If you have information about an emergency or are concerned about a release of hazardous materials that is in progress, please call the Minnesota Duty Officer at:
