OAKLAND, Ca. – Seventy-seven Harvard student volunteers experienced a nearly 70 percent increase in urinary levels of bisphenol A (BPA), a plastics component and synthetic estrogen linked to cancer, reproductive system damage and other serious conditions, after drinking cold beverages from BPA-laden polycarbonate bottles for just one week, according to researchers from Harvard University and the U.S. Centers for Disease Control and Prevention (CDC).
The ground-breaking Harvard/CDC study, led by Karin B. Michels, a Harvard professor of epidemiology, and published May 12 in the online version of the journal Environmental Health Perspectives poses serious implications for the impact of BPA exposure on infants fed with polycarbonate bottles.
The Harvard/CDC study buttresses a March 2007 study by EWG that documented that BPA-based epoxy can linings had contaminated more than half the canned foods, beverages and canned liquid infant formula randomly purchased at supermarkets around the country. Since many of the foods tested, such as liquid infant formula, canned soup and SpagettiOs, are marketed for babies and toddlers, babies drinking from BPA-plastic bottles and sippy cups and eating canned food could receive significant doses of the chemical, shown in laboratory studies to cause serious damage to brain and reproductive systems of test animals. As well, the chemical has been associated with cardiovascular damage, diabetes, obesity and other chronic conditions.
In the absence of any U.S. regulation on BPA contamination of food, EWG has published an online guide to baby-safe bottles and formula.
EWG supports State Senator Fran Pavley's (D) measure to ban BPA in California.
At the federal level, U.S. Senator Dianne Feinstein (D-CA) and Rep. Edward Markey (D-MA) have introduced legislation that would restrict the use of BPA in food and beverage containers.
"If the legislation to protect California's youngest from further exposure to BPA is defeated, those elected officials responsible for its demise should be held to account for protecting the profits of the chemical industry instead of children's health," added Sharp.
In March, Connecticut Attorney General Richard Blumenthal announced that 6 major companies -- Avent, Disney First Years, Gerber, Dr. Brown, Playtex and Evenflow -- had volunteered to stop using BPA-based plastic in baby bottles made for the U.S. market.
Several major retailers, including Wal-Mart and Toys R' Us, have announced they would stop selling baby bottles made with BPA. The water bottle manufacturer Nalgene and several of the nation's largest baby bottle makers are phasing BPA out of their products. The petro-chemical giant Sunoco has promised that it would no longer allow any of the BPA it makes to be used in items designed for children 3 and under.
