BPA Found To Leach From Polycarbonate Drinking Bottles Into Humans
ScienceDaily (May 22, 2009) — A new study from Harvard School of Public Health (HSPH) researchers found that participants who drank for a week from polycarbonate bottles — the popular, hard-plastic drinking bottles and baby bottles — showed a two-thirds increase in their urine of the chemical bisphenol A (BPA). Exposure to BPA, used in the manufacture of polycarbonate and other plastics, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease and diabetes in humans.
BPA is also found in dentistry composites and sealants and in the lining of aluminum food and beverage cans.
The study 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.
