MDHHS’s MiChEM project is the first statewide effort to gather data on the amount of certain chemicals in the blood and urine of Michiganders, including lead, mercury, and PFAS.

People can come in contact with chemicals in what they eat and drink, in products they use, at work, and in their environment, like in the air, soil, and water. Some chemicals are helpful and necessary for life and some can be harmful. Either way, this contact with chemicals is called a chemical exposure.

Purpose of the MiChEM Project

It’s important that people of different races, ethnicities, age groups, and parts of the state participate in MiChEM to better understand whether certain groups have more of certain chemicals in their blood and urine. MiChEM will help MDHHS and other agencies know what actions to take to reduce chemical exposures. These actions could include:

MiChEM is measuring 197 chemicals:
