Synopsis by Jonathan Chevrier, Ph.D.

A new study finds associations between exposure to bisphenol A (BPA) and the blood levels of thyroid and reproductive hormones.

Bisphenol A (BPA) can affect hormone levels in animals, and some recent studies suggest the widely used compound may have similar effects in people.

More than 90 percent of the U.S. population is exposed to BPA, most likely through diet. The chemical was first manufactured in 1891 and has since been shown to have estrogenic properties in animals.

Very few studies have examined whether BPA may affect hormone levels in humans. The results of this study are published in the journal Environmental Science and Technology and add to that growing body of research.

Many consumer products contain BPA. Most notably, it is found in some types of hard, polycarbonate plastic baby and water bottles – although many manufacturers have recently removed it from baby and children’s items. The lining of food and beverage cans, some dental fillings and sealants and thermal paper may all contain BPA.
