BPA from bottles enters the human body
The proof is in the pee? Bisphenol A (BPA) is suspected to be an endocrine disruptor and a potential cause of numerous chronic diseases, leading to various efforts to ban its use. A newly released study by researchers at Harvard and the Centers for Disease Control finds bottles made from BPA lead to BPA uptake by humans, with some of it being excreted in urine. The researchers had 77 Harvard College students drink cold beverages from stainless steel bottles for one week, then from BPA-containing polycarbonate bottles during the following week, with periodic urine sample collection for analysis. Use of the polycarbonate bottles led to a 69% increase in the subjects' urinary concentration of BPA. (Environmental Health Perspectives)
