Poop Causes Estrogen Pollution

Women using birth control pills don't have to worry they may be contaminating the water and causing mutation in the sexual organs of frogs, alligators and other animals.

Birth control pills account for less than 1 percent of the estrogen found in rivers, lakes and other bodies of water, said researchers at the University of California, San Francisco.

Untreated animal manure is the real culprit, said Amber Wise, Kacie O'Brien and Tracey Woodruff in the American Chemical Society's Environmental Science and Technology journal.

Manure accounts for 90 percent of the estrogen contaminating the water according to their synthesis of research on estrogen pollution. Soy, dairy products and other natural sources account for a larger percentage than the pill as well.

To determine the sources of estrogen contaminating the environment, the researchers reviewed previous studies and synthesized their findings.

High levels of estrogen in the water have been linked to the feminization of amphibians, and reproductive problems for other animals such as alligators.
