The study results, published in Environmental Health Perspectives, have renewed concern and calls for regulation.
“The study reinforces the urgent need for stricter government oversight and regulation of this extremely toxic chemical,” said Janet Nudelman, director of program and policy at the Breast Cancer Fund, one of our favorite health advocacy groups. “It adds to what we already know about BPA, a chemical so powerful that at extremely low levels — parts per billion or even parts per trillion — it can cross the placenta and alter the mammary gland of the developing fetus, increasing breast cancer risk later in life.”
Now here's the scary party: BPA (used to make baby bottles, dental sealants, food containers and thousands of other household products) was found in 93% of Americans tested.
The new study, conducted by Richard Stahlhut at the University of Rochester, used data on humans collected by the U.S. Centers for Disease Control and Prevention. Researchers looked at urine samples of 1,469 U.S. adults. They compared the levels of BPA based on how long the subjects had fasted.
BPA has been linked to spikes in breast cancer, diabetes and heart disease, even at very low levels. It has also been found to interfere with chemotherapy in breast cancer patients.
“It provides evidence that we are being exposed to more BPA than we think — and that contaminated food and beverages may not even be the main source “ of our BPA exposure, said Patricia Hunt, a professor at Washington State University who pioneered studies linking BPA to cancer. “Scary, huh?”
