Researchers have just linked prenatal exposure to bisphenol-A – a near-ubiquitous industrial chemical – with subtle, gender-specific alterations in behavior among two year olds. Girls whose mothers had encountered the most BPA early in pregnancy tended to become somewhat more aggressive than normal, boys became more anxious and withdrawn.
This is the first study to link human behavioral impacts with BPA, a common ingredient in hard polycarbonate plastics and the resins used in food-can linings. Emerging data from an unrelated research group points to another especially rich newfound source of BPA to which people unwittingly may be exposed: thermally printed cash-register receipts (see next blog).
