DEHBio - Biomonitoring and PFAS Health Studies

The Michigan Department of Health and Human Services currently has multiple biomonitoring research projects and health studies underway.

These projects will help us learn about:

  • Our Exposures: What types of chemicals Michiganders are exposed to
  • Our Environment: How much exposure people could be getting from the Michigan environment
  • Our Health: How these chemicals affect the health of Michiganders


There are three types of projects in DEHBio: biomonitoring, exposure assessments, and health studies. The information gathered from these projects can be used to help recommend changes to public health policies and better protect communities that may be at greater risk of exposure. Learn more about each of these types of projects.


Below are past and current DEHBio projects. Click on the link in the description to find out more about each project.

Multi-Site Health Study

Launched 2021

The Multi-Site Study (MSS) is a study coordinated by the Center for Disease Control's Agency for Toxic Substances and Disease Registry (ATSDR) in partnership with MDHHS. It is happening in seven communities across the U.S., including the same Michigan communities as MiPEHS.

Michigan PFAS Exposure & Health Study (MiPEHS)

Launched 2020

Enrollment for the 2nd phase of this study begins in 2023. Please see our Contact Us page if you are interested.

The Michigan PFAS Exposure and Health Study, or MiPEHS (pronounced: my-pez-), is a longitudinal study to research exposures to PFAS and health in the Michigan communities of: the City of Parchment and Cooper Township in Kalamazoo County and the Rockford/Belmont Area in Kent County.

Michigan Chemical Exposure Monitoring (MiChEM)

Launching 2022

MiChEM (pronounced: my-chem) is a statewide biomonitoring project focused on a representative sample of Michigan adults. MDHHS will look at the blood and urine of these adults for certain chemicals. The project aims to find the statewide average level of exposure to these chemicals.

PFAS Exposure and Antibody Response to COVID-19 Vaccine Study

Launched April 2021

Not Currently Enrolling Participants

The Michigan Department of Health and Human Services (MDHHS) is doing a research study to see if per-and polyfluoroalkyl substances (PFAS) exposure affects how the immune system responds to COVID-19 vaccines, including antibody production.

PFAS in Firefighters of Michigan Surveillance (PFOMS)

Launched April 2021

Now Enrolling Participants

The PFOMS (pronounced: p-foams) project is a statewide biomonitoring project focused on Michigan firefighters. The primary purpose of the project is to determine firefighters' average exposure to per- and polyfluoroalkyl substances (PFAS). The findings of the project will help inform decisions about how to minimize firefighters' exposure to PFAS.

North Kent County Exposure Assessment

Launched 2018

Not currently enrolling participants.

The North Kent County Exposure Assessment is a regional effort that studied the relationship between drinking water with PFAS and the amount in the human body. The research study involves collecting blood samples from people in the northern Kent County area whose drinking water wells were found to have PFAS.

MDHHS Michigan Long-term Poly-Brominated Biphenyls (PBB) Study


Emory University Poly-Brominated Biphenyls (PBB) Study


The MDHHS Michigan Long-Term Poly-Brominated Biphenyls (PBB) Study sought to identify long term health impacts associated with PBB exposure in thousands of Michiganders following an accidental release of the chemical into the food supply in the early 1970s. Although enrollment in the MDHHS study ended in 2004, MDHHS continued to update the study's databases until 2009. Currently, Emory University is carrying on similar PBB research and their study is open to enrollment.
