herbicide hormone havoc

The Washington Post is reporting on yet another study that shows that the widely-used herbicide, Atrazine, scrambles hormones in wildlife.

In this study, Dr. Tyrone Hayes at UC-Berkeley found that male frogs who as tadpoles swam in water tainted with low levels of Atrazine (within the US EPA's drinking water limits) developed female sex traits. 10% of the male frogs even laid eggs that hatched!

Syngenta, the chemical company that makes Atrazine, continues to stick to their story that Atrazine does no such thing. Every study they've released shows the opposite.

Meanwhile, the US EPA is taking another look at Atrazine, which they re-registered for use in 2006 based on Syngenta's safety data. It seems all this independent research has shown things in a different light. Perhaps EPA will start making a practice of considering independent research - not just the company's own data - when evaluating a pesticide's risks. It would be long overdue.
