Bisphenol A may have hormone disrupting effects that last for several generations. BPA is a component of the plastic that is used in the lining of metal cans. It is also found in many cash register receipts. Researchers at the University of Virginia exposed pregnant mice to low levels of BPA. Their offspring demonstrated behavioral changes, including anxiety, aggressive behavior and reduced cognitive function. The epigenetic changes were detectable in the second, third and even the fourth generation. If the mouse research were extrapolated to humans, it might mean that the grandchildren and great grandchildren of women exposed to BPA today could experience negative effects for years to come.
