The scientific journal, Environmental Health Perspectives, just published the shocking results of a new study done by Harvard University and Centers for Disease Control Prevention. The levels of bisphenol-a in the urine of 77 Harvard increased by two-thirds after they drank cold liquids from BPA water bottles for only a week.
Whether or not the intake of food and drinks from polycarbonate containers increases BPA concentrations in humans had not yet been studied. This study was designed to examine the association between the use of polycarbonate beverage containers and urinary BPA concentrations in humans. The study's conclusion was straightforward and alarming.
One week of polycarbonate bottle use increased urinary BPA concentrations by two thirds. Regular consumption of cold beverages from polycarbonate bottles is associated with a substantial increase in urinary BPA concentrations irrespective of exposure to BPA from other sources.
It's becoming more clear that BPA is harmful at lower levels than previously suspected and that sources of exposure are numerous and often hidden. Recent studies have also shown that BPA remains in the blood longer and is not metabolized as quickly as once thought.
It's extremely important that we help the most susceptible individuals, pregnant women and children, to avoid known sources of BPA exposure. Renee Sharp, Director of Environmental Working Group's California office responded with great clarity on this point:
These astonishing results should be a clarion call to lawmakers and public health officials that babies are being exposed to BPA, and at levels that could likely have an impact on their development. The adults in this study were willing participants who understood the risk of exposure, but babies are unwitting victims of the silent but serious threat this hormone- disrupting chemical poses to their health.
