BPA in the news again.
A study commissioned by Environmental Working Group (EWG) have found high levels of the endocrine-disrupting chemical bisphenol A (BPA) on 40 percent of store receipts they analyse.
BPA, a plastic hardener used to coat some thermal paper reacts with dye to form black print on store and ATM’s receipts.
Wipe tests conducted by the lab easily removed BPA, indicating that the chemical could rub off on the hands of a person handling the receipt.
Scientists have not determined how much of a receipt’s BPA coating can transfer to the skin and from there into the body. A study published July 11 by scientists with the Official Food Control Authority of the Canton of Zürich in Switzerland found that BPA transfers readily from receipts to skin and can penetrate the skin to such a depth that it cannot be washed off. This raises the possibility that the chemical infiltrates the skin’s lower layers to enter the bloodstream directly.
The BPA coating on receipt paper is an obvious concern for shoppers, but even more so to for the legions of people who staff cash registers and bag groceries at tens of thousands of retailers across the country.
