Back in May, I pointed to a study on a farm chemical that was found to cause physiological and behavioral changes in rats. Worryingly, the effects persisted for generations after a single exposure (it was the first time this phenomenon was extensively documented in an industrial chemical). In an email at the time, one of the study authors said, “Many other environmental compounds promote these types of phenomena … Future science and policy needs to consider such phenomena and mechanisms.”

It looks like he was right. Now, another study has found evidence of multi-generational effects of exposure — in this case, to that ubiquitous endocrine disruptor you love to hate: bisphenol A (BPA). The research appears in the peer-reviewed journal Endocrinology and was conducted by a team of scientists from the University of Virginia. Its title says it all: “Gestational Exposure to Bisphenol A Produces Transgenerational Changes in Behaviors and Gene Expression.”
