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.

Behavioral Adaptability: Learning About Novel Contamination in the Environment (BALANCE)

Launched 2023

Currently enrolling new participants.

This study is designed to understand certain characteristics of health and behavior, and how those may be related to learning about blood or water test results or other environmental chemicals.

Michigan Chemical Exposure Monitoring (MiChEM)

Launched 2022

Currently Enrolling Participants

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.

Oscoda Area Exposure Assessment logo

Oscoda Area Exposure Assessment (OAEA)

Launched September 2022

Currently Enrolling Participants

The OAEA is carried out as one part of the Michigan biomonitoring surveillance program named the Michigan Chemical Exposure Monitoring project, or MiChEM. To learn more about MiChEM, visit our MiChEM page.

OAEA is an exposure assessment to understand exposure to environmental chemicals, including per- and polyfluoroalkyl substances (PFAS), among residents of the Oscoda area. MDHHS will test blood from both adolescent and adult participants for PFAS. Adults (18 and older) can have their blood and urine tested for additional environmental chemicals. The project will measure the Oscoda area population’s exposure to environmental chemicals and compare the findings to statewide average levels of exposure as measured by the MiChEM project and national average levels of exposure as measured by the CDC.

Multi-site Health Study 

Launched 2021

Not Currently Enrolling Participants

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.

The Birth Outcomes Supplemental Study (BOSS) is a special addition to the Multi-site Health Study that only Michigan is doing. BOSS is designed to answer how PFAS exposure relates to a mother and baby’s health during birth. Learn more about BOSS

Michigan PFAS Exposure & Health Study (MiPEHS)

Launched 2020

Not currently enrolling. MiPEHS Phase 2 ended on 8/12/2023. Phase 3 begins in early 2025. If you have questions about the study please call study staff at 844-464-7327.

The first results from MiPEHS Phase 1 (2020-2021) are available! To see the first results from Phase 1, read the Phase 1 Summary Report. If you would like more detail than what is included in the Summary Report, read the Technical Appendix to the Summary Report. There is more to come!

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.

PFAS Exposure and Immune Response to COVID-19 Vaccination Study - Study Name Graphic

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

Not Currently 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 Report 2 is now available!

Learn about the North Kent County Exposure Assessment Report 2.

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.

PBB Studies

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


Emory University Poly-Brominated Biphenyls (PBB) Study
Currently Enrolling Participants

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.
