What is biomonitoring?

People are exposed to chemicals through their everyday environment.  Many chemicals are harmless, but continuous exposure to some chemicals may cause long-term health problems. Chemicals enter our bodies through air, water, food, soil, dust, and commercial products.  Through biomonitoring, scientists study chemical exposures by testing how much of those chemicals get into the body.  This important work helps us understand chemical exposures and find ways to protect potentially vulnerable populations or communities. 

Why is biomonitoring important?

Chemicals are all around us.  Some chemicals are harmless, while others may cause illness or contribute to diseases. 

We use the data gathered from this study to help identify chemicals that may enter our bodies and cause harm.  The information also helps us understand if there are certain populations or communities in Iowa at higher risk of exposure.   

Our biomonitoring program expands our knowledge about chemical exposures in Iowa and allows public health experts to make important decisions to protect you, your family, and your community.  

How do I learn more about biomonitoring?

Iowa is one of six states to receive a five-year biomonitoring  grant through the Centers for Disease Control and Prevention in 2019 and is a member of the National Biomonitoring Network (NBN).  The NBN is a collaboration between the CDC, the Association of Public Health Laboratories (APHL) and state public health laboratories, such as the State Hygienic Laboratory in Iowa.
