From Headlines to Data: Inside the Iowa Exposure Study

Across Iowa, a growing number of reports are raising questions about environmental exposure and public health.

Recent analyses point to a combination of factors—including pesticides, nitrate contamination, PFAS (“forever chemicals”), and radon—as potential contributors to the state’s rising cancer rates. Iowa is now among the few states where cancer incidence is increasing, with rates exceeding the national average and affecting both rural and urban communities.

These findings have sparked important conversations—but they also highlight a critical gap: We often talk about environmental risk—but rarely measure what’s actually in the body.

The Missing Link: Measuring What’s in the Body

Environmental data—such as water quality testing or pesticide application rates—can provide valuable insights. However, they do not reveal how much of these compounds are actually entering the human body.

Exposure is highly individual. It varies based on:

• where you live
• your occupation
• seasonal factors
• lifestyle and diet

Without direct measurement, exposure remains an assumption.
