Les pesticides créent des grenouilles hermaphrodites

WASHINGTON (AP) -- Male frogs exposed to even very low doses of a common weed killer can develop multiple sex organs -- sometimes both male and female -- researchers in California have discovered.
"I was very much surprised," at the impact of atrazine on developing frogs, said Tyrone B. Hayes of the University of California at Berkeley.
Atrazine is the most commonly used weed killer in North America, he said, and can be found in rainwater, snow runoff and ground water.
"There is virtually no atrazine-free environment," Hayes said.
The Environmental Protection Agency permits up to 3 parts per billion of atrazine in drinking water.
But Hayes' team found it affected frogs at doses as small as 0.1 part per billion. As the amount of atrazine increased, as many as 20 percent of frogs exposed during their early development produced multiple sex organs or had both male and female organs. Many had small, feminized larynxes.
