Mice exposed to bisphenol A (BPA) during pregnancy give birth to offspring with atypical brain development and abnormal behavior later in life, according to a study presented yesterday (March 19) at the annual meeting of the Endocrine Society in Chicago.

Previous studies have linked BPA, which is found in a wide array of consumer products including plastic water bottles, to numerous diseases. In 2015, Deborah Kurrasch, a neuroscientist at the University of Calgary, and her colleagues found that the chemical can also alter brain development and cause hyperactivity at low doses in zebrafish.

Kurrasch and her colleagues then decided to investigate whether similar alterations occurred in mammals, Dinu Nesan, a postdoctoral fellow in Kurrasch’s lab, said during a presentation. After feeding pregnant mice meals containing ...
