In the early 2000s, scientists have determined that the nation's top-selling weed killer, atrazine,
disrupts the sexual development of frogs at concentrations 30 times lower than levels allowed by the
Environmental Protection Agency (EPA), raising concerns about heavy use of the herbicide on corn,
soybeans and other crops in the Midwest and around the world. The amphibians (the frogs) are exposed
to atrazine when in water.
