WASHINGTON – As lawmakers and health experts wrestle over whether a controversial chemical, bisphenol-A, should be banned from food and beverage containers, a new analysis by an environmental group suggests Americans are being exposed to BPA through another, surprising route: paper receipts.

In some cases, the total amount of BPA on the receipt was 1,000 times the amount found in the epoxy lining of a can of food, another controversial use of the chemical. Sonya Lunder, a senior analyst with the environmental group, says BPA's prevalence on receipts could help explain why the chemical can be detected in the urine of an estimated 93 percent of Americans, according to the Centers for Disease Control and Prevention.
