Connecticut has become the second state to ban the sale of polycarbonate baby bottles, food containers, cups and infant formula cans that contain bisphenol A.
The state joins Minnesota, the city of Chicago and Suffolk County, N.Y., which earlier this year passed similar measures.
The Connecticut ban, expected to be signed by Gov. M. Jodi Rell, because of its overwhelming legislative support, is scheduled to take effect Oct. 1, 2011. It applies to reusable food and beverage containers and spill-proof cups, plastic bottles and infant formula cans that contain BPA and are intended for children 3 and younger.
A controversial labeling requirement was stripped from the bill by the state's Senate, necessitating a second vote of approval by the House on May 22.
Michigan, New York, California and Schenectady County, N.Y., are weighing similar proposals. At the federal level, three U.S. senators introduced a bill in mid-March to ban the use of BPA in all food and drink containers.
Meanwhile, a study released earlier this month is drawing attention to BPA in PC drink containers. The Harvard School of Public Health found that a group of 77 students who drank cold beverages for one week exclusively from PC water bottles had BPA levels in their urine that were 69 percent higher than at the end of the previous week when they used stainless-steel bottles.
Drinking cold liquids from polycarbonate bottles for just one week increased urinary levels of BPA by more than two-thirds, said Karin Michels, associate professor of epidemiology, who was the study's senior investigator. It was published May 12 in Environmental Health Perspectives.
But the PC/ BPA global group of the plastics division of the American Chemistry Council said the BPA level in the students' urine was lower than what the Centers for Disease Control and Prevention cites as the average level for the U.S. population.
