Chemicals of High Concern
Background
The Toxic Free Kids Act required that Minnesota Department of Health (MDH), after consultation with the Minnesota Pollution Control Agency (MPCA), generate a list of chemicals of high concern (CHC) by July 1, 2010. The chemicals had to meet these criteria identified in Minnesota Statutes, section 116.9401:
"Chemical of high concern" means a chemical identified on the basis of credible scientific evidence by a state, federal, or international agency as being known or suspected with a high degree of probability to:
1. Harm the normal development of a fetus or child or cause other developmental toxicity.
2. Cause cancer, genetic damage, or reproductive harm.
3. Disrupt the endocrine or hormone system.
4. Damage the nervous system, immune system, or organs, or cause other systemic toxicity.
5. Be persistent, bio-accumulative, and toxic.
6. Be very persistent and very bio-accumulative.
The law also instructs MDH to consider chemicals that fit the above criteria by a state, federal, or international agency. These agencies may include but are not limited to the following: the California Environmental Protection Agency, the Washington Department of Ecology, the United States Department of Health, the United States Environmental Protection Agency, the United Nation's World Health Organization, and European Parliament Annex XIV concerning the Registration, Evaluation, Authorisation, and Restriction of Chemicals.
MDH is required to update the chemical list at least every three years. The most recent update was published on July 21, 2025. The next update is due to be published in July 2028.
The following drop-down menus provide the current (2025) chemical list as well as other details regarding the update.
The revised 2025 chemicals of high concern list can be downloaded from the links below. A report describing the revision and review process for the list can be found on the Reports page or in the dropdown report section below.
The chemicals of high concern list was first published in 2010. MDH is required to review and revise the list at least every three years. If you wish to view the original 2010 list or previous updates, please contact MDH at 651-201-4899 or health.risk@state.mn.us with your request.
