Two articles were released today with more data about the harm of BPA, both from the Environmental Health News
Study predicts BPA in babies 11 times higher than adults
Using a mathematical model based on enzymatic differences between newborns and adults, scientists estimate that the amount of bisphenol A (BPA) circulating in the blood of babies is more than 11 times higher than the amount in adult blood. The striking disparity is most likely due to natural differences in metabolism and body size between babies and adults. This study points to the need for chemical exposure standards to better incorporate differences in vulnerabilities between children and adults.
The results suggest tht children are very likely to be the most severely affected by exposure to BPA and related endocrine disruptors.
In this first study examining infants’ exposure to bisphenol A, premature babies hospitalized in neonatal intensive care units had levels of BPA in their urine 10 times higher than the general population. The source of exposure most likely was plastic medical devices used in the hospital, although some could have come from infant formula. BPA is a plastic compound that is linked to various health abnormalities in humans and lab animals.
This study’s findings show that premature babies (already born with developmental and physiological limitations) are further challenged by exposure to a compound known to negatively impact health.
