Lakes and rivers around the world are polluted with synthetic hormones that have negative effects on wildlife, causing male fish, for instance, to become feminized and produce eggs.

A team of U.S. and British scientists now think they may have hit upon a solution based on a common household chemical — hydrogen peroxide.
