Dear XXX,

Atrazine. It's a chemical so potent that male frogs exposed to low levels of it can turn into female frogs - producing perfectly viable eggs. This same chemical is a widely-used herbicide whose residues have been found on most American corn crops and atrazine contamination of U.S. drinking water is widespread.

This is not a joke.

If atrazine can - and does - alter the anatomy of frogs, imagine the havoc it could wreak on the human body.

We highlight the effects of atrazine in EWG's Dirty Dozen Endocrine Disruptors, produced in partnership with the Keep a Breast Foundation. Our groundbreaking research lists a dozen chemicals - atrazine among them - that are some of the most harmful to the endocrine system. This informative booklet describes 12 of the worst hormone disruptors, how they do their dirty deeds and some tips on how to avoid them.

It's reports like this that make EWG's work so critical, but we can't take on these fights without your help.

Because you value EWG’s one-of-a-kind research and advocacy work, please support EWG with a gift of $15 or more. If you act before August 27, we will send you a copy of our Dirty Dozen Endocrine Disruptors booklet so that you can learn how to minimize your exposure.

You had questions about endocrine disruptors and their potential effects on our bodies. Our research team delivered. We've been at the forefront of this research from the beginning, calling on corporations to remove these and other potentially dangerous chemicals from their products and for smarter government regulation.

And our work has already made waves - Johnson & Johnson and other cosmetics companies have pledged to remove formaldehyde-releasing preservatives and other chemicals of concern from some of their products.

But there's more to be done. These chemicals continue to enter the market, sheltered by mislabeled products and weak regulations. EWG's research team has rolled up its sleeves, and we're ready to keep working, but we're only able to take on these tough fights with the help of individuals like you.

Don't delay - click here to give $15 or more today to support EWG's innovative research, like the Dirty Dozen Endocrine Disruptors booklet.

Remember, if you act now, we will send you our Dirty Dozen Disruptors booklet.

Thank you for your support,
