WHY WORRY?

  • Herbicide use in the Midwest is rapidly rising and 2,4-D and dicamba — two older, high-risk herbicides — account for most of the increase

  • Herbicides may be triggering heritable epigenetic changes that impair a child’s development or increase the risk of adult-onset disease

KEY RESEARCH QUESTIONS

  • How have prenatal herbicide exposure levels changed over time?

  • Are herbicides contributing to heritable, epigenetic changes in newborns across the Midwest?

  • How can we determine which herbicides pose the greatest risks, and which are low-risk?

Heartland Study Response

We will answer the key research questions above by exploring linkages between herbicide exposure during pregnancy and birth outcomes in at least 2,000 mother-infant pairs.

The Heartland Study will pioneer new methods of understanding the simultaneous impact of exposure to multiple herbicides, and be the first ever to track markers of epigenetic change from herbicide exposures in a human population.
