Should pregnant women avoid the Atrazine herbicide on lawns and farms?
Yes. Maternal atrazine exposure causes neurotoxicity that passes to offspring.
What's actually in it
Atrazine is one of the most-used herbicides in the US. It treats corn fields and gets into drinking water in farm states. The European Union banned it years ago. The chemical is a known endocrine disruptor that can also cross the placenta.
What the research says
A 2026 study in Ecotoxicol Environ Saf exposed pregnant animals to atrazine at human-relevant doses. The mom's plasma metabolites were remodeled, which then drove neurotoxicity in offspring. The harm passed from one generation to the next through metabolic chemistry, not direct contact.
Filter tap water with a carbon block, especially if you live in the corn belt. Skip atrazine-based weed killers around the house. Stay indoors when farm fields nearby are being sprayed. Wash produce well. Pick organic for sweet corn, the most likely atrazine-residue food.
