People in some Minnesota communities are routinely exposed to pesticide drift from nearby farm fields, according to a new study released Thursday. The chemical in question, a commonly used fungicide called chlorothalonil, is under increasing scrutiny. California-based Pesticide Action Network compiled the data for the Minnesota study. The organization's lead scientist Emily Marquez says current Environmental Protection Agency regulations of chlorothalonil don't consider that people might be exposed by inhaling the chemical. Marquez says this study is evidence the regulations need to change.
