BPA-free doesn't mean estrogen free


IStock_000006558719Medium_webA new study in Environmental Health Perspectives found that most plastic containers that come  into contact with food or beverages leach chemicals that mimic estrogen, even when they are advertised as being BPA-Free.

Bisphenol A has been under fire in recent years because it is a compound used in products like baby bottles and sippy cups which releases an estrogen-like chemical that disrupts hormones in the human body. The exposure is believed to be problematic especially in children's products, because their bodies are still developing, making them more vulnerable.

The controversy over BPA has led many countries (Canada was the first) and states in the U.S. (Minnesota was the first) to ban it in certain products. Consumers have also become increasingly concerned about the chemical and have switched to buying BPA-free alternatives.

Researchers purchased more than 450 product samples between 2005 and 2008 to test for leaching of estrogen-like chemicals in common plastic products that come into contact with food and/or beverages. The tests included polycarbonate baby bottles (which contains BPA), and also products that are marketed and labeled as being "BPA-Free."

The testing found that most (over 70 percent) of the products released estrogen-like chemicals when initially tested. After exposing products to simulated sun exposure and heating, the percentage increased to over 90 percent.

The new study reminds us that we can't phase out chemicals on a case by case basis. The Toxic Substances Control Act (TSCA) is the federal law meant to regulate chemicals in the United States but it is flawed and badly broken, allowing manufacturers to substitute one problem chemical with others that may also be problematic.

It's time for chemical companies to stop playing games with our health. We need real reform that protects people, especially the most vulnerable among us, from exposure to toxic chemicals.
