It’s scary to think about how many toxins are out there in the world, believe me I know. If it isn’t one thing it’s another—pesticides in our food, pollutants in our air, chemicals in our tap water—but what if it wasn’t just you that you had to worry about?

If you or someone you know is expecting, you’ll want to check out this website: The Endocrine Disruption Exchange is a non-profit organization dedicated to studying the effects of low-dose exposure to harmful chemicals called “endocrine disruptors” on fetal development and human health. Endocrine disruptors are like imposters in your body, and they basically act like hormones and interfere with normal physiological function.

On their website is an amazing interactive chart that shows the effects of three common endocrine-disrupting chemicals—bisphenol A (BPA), dioxins, and phthalates—during each week of fetal development, and they plan to add more chemicals to the chart as they continue to analyze the available scientific evidence.

It may seem a little too technical at first, but the visual is really neat. When you click on a specific chemical, it shows you just how low of a dose of that chemical can affect the healthy development of a baby in the womb. They even provide a summary of each study so you can learn more. Be sure to check it out!
