Michigan Investigation of Chemical Exposures during Pregnancy (MICEP) is a project that measures arsenic, mercury, lead and per- and polyfluoroalkyl substances (PFAS) in the blood and urine of those who are pregnant and live in certain areas of the state. MICEP will determine whether amounts of these chemicals are different during pregnancy compared to the United States and Michigan populations.
Purpose of the MICEP Project
MICEP findings will help MDHHS improve educational materials and inform current and future programs aimed at reducing exposures during pregnancy to chemicals in the environment. Data will be used to:

Investigate sources of chemical exposures.

Create programs to teach people how to reduce chemical exposures during pregnancy.

Inform groups that make rules about chemical use.
42 environmental chemicals measured by MICEP
- Lead
- Arsenic

More information about these chemicals can be found on the MICEP Resources Page.
