There's interesting, and somewhat concerning, news this week about bisphenol A (BPA), a chemical found in some plastic bottles and canned goods. According to a study from the University of North Carolina at Chapel Hill, there appears to be a link between prenatal exposure to BPA and aggessive behavior in toddler girls (though not boys).Researchers tracked 249 women during pregnancy and beyond and found that girls exposed to high levels of BPA early in their mom's pregnancy exhibited more signs of aggression and hyperactivity at age 2 than girls exposed to lower BPA levels.As WebMD reports, none of the girls' behavior reached a "level of clinical concern," and the scientists say more research is needed. But this is the first study to determine whether prenatal exposure to BPA can impact childhood behavior, and I imagine this isn't the last we've heard of the issue.Previously: Bye, bye BPA baby bottlesPhoto by darrylh
