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. [atrazine frog Given that log Kow for atrazine is 2.65 and that log 0.85 log Kow - 0.07. %3D [atrazine]pater If the atrazine concentration in the water is 100 ng/L, what would be the concentration of atrazine in frogs in ppm?
