A few weeks ago the U.S. National Toxicology Program (NTP) released the results of the largest study ever conducted on bisphenol A (BPA). The CLARITY Core study was conducted by senior scientists with the U.S. Food and Drug Administration (FDA) in their own laboratory in Arkansas known as the National Center for Toxicological Research (NCTR).

If you pay attention to labels on food and beverage containers, you’ve probably seen quite a few labels indicating that a product is BPA-Free. But what does that mean and why is it there?

The term “environmentally relevant dose” is commonly used to characterize the dose of a chemical that is given to laboratory animals in scientific studies. More specifically the term is used to signal that the results of the study are important.
But what does the term actually mean? Presumably it means that the dose given to laboratory animals is comparable (i.e., relevant) to the levels that people are actually exposed to from their environments (e.g., from diet, drinking water, air).

You may have already heard that the U.S. National Toxicology Program recently released the results of an important new study on BPA known as the CLARITY Core study. One reason it’s important is because the goal of the study was to resolve any remaining uncertainties about the safety of BPA, which has been a controversial topic for quite some time.

For more than 10 years, U. S. government scientists have been conducting an in-depth research program with the goal of answering key scientific questions and resolving any remaining uncertainties about the safety of BPA. And oh what a program it’s been!

Judging by the headlines in major UK newspapers a few days ago, it must have been a slow news day. Using the scariest of terms, as headline writers are prone to do to catch your attention, the stories reported that teenagers in the UK are exposed to BPA.
The “scare appeal” of the headlines is obvious. And what the stories reported is not exactly news, although it did fill space in the newspapers. So how does one small study garner so much media attention?

A common feature of many winter sports events is that they involve racing down a mountain at high speed, sometimes under icy conditions if not literally on ice. Any kind of crash could be disastrous, not only for a chance at a medal, but because of the bodily injury that could result.

It’s not hard to find products labeled as BPA-Free these days. For example, you’ll find more than 100,000 results if you search Amazon.com for the term “BPA-Free.” Even manufacturers of products that never contained BPA in the first place get in on the action, for example the BPA-Free glass food storage containers shown on the first page of the Amazon.com results. Some manufacturers go further to provide information on BPA and why they think you should avoid it.

Most likely you’ve never heard of Paracelsus, a Swiss physician from the 14th century, but you live every day with a toxicology principle that he created. That principle, simply stated as “the dose makes the poison,” has stood the test of time for about 500 years.
