Brief description of study
DID YOU KNOW? Herbicides are widely used in the Heartland, and farmers are using these chemicals more than ever before. Several studies have raised concern that some of the herbicides may be associated with reproductive disorders, certain birth defects, and developmental disorders.
What are herbicides?
Herbicides are a type of pesticide that are used to protect our food crops, trees, vines, and pastures from harmful weeds. Some herbicides are also used in and around our homes, parks, sports fields, and golf courses. Herbicide use has increased significantly since the 1990s and is projected to rise rapidly on corn and soybean farms in the Midwest for the next 5-10 years. As more pounds are applied, higher levels of human exposure are expected.
What Is the Heartland Study?
Mother-infant pairs living in the Midwest will be followed throughout pregnancy, infancy and early childhood to observe health and development in order to better understand the effects of prenatal herbicide exposures.
Your participation will help researchers to increase their knowledge about how herbicide exposure might affect pregnancy, newborn health, child childhood development, and future generations.
