New study finds drinking from polycarbonate bottles increases level of urinary BPA

09-Sep-09

A study from the Harvard School of Public Health (HSPH) is the first to show that drinking from polycarbonate bottles increased the level of urinary BPA, and thus suggests that drinking containers made with BPA release the chemical into the liquid that people drink in sufficient amounts to increase the level of BPA excreted in human urine. The study revealed that participants who drank for a week from polycarbonate bottles and baby bottles showed a two-thirds increase of BPA in their urine. It was found that drinking cold liquids from polycarbonate bottles for just one week increased urinary BPA levels by more than two-thirds. Higher levels of BPA could be expected if the bottles are to be heated, like in baby feeding bottles- This would be of concern since infants may be particularly susceptible to BPA's endocrine-disrupting potential.
