According to an article in the L.A. Times, the Environmental Working Group recently reported that high amounts of Bisphenol A , also known as BPA, are present in cash register receipts:
In addition to plastic bottles and food can linings, bisphenol A is found in the chemical coating of some thermal papers — the type used in cash registers that turn color when exposed to heat.
Certainly, there would be real concerns if the bisphenol A on receipts readily sloughs off onto the fingers of cashiers and buyers, penetrates several layers of skin and enters the bloodstream at potentially toxic levels, says Kristina Thayer, a scientist at the National Toxicology Program. However, she added, no scientific study has even looked for such a pathway….
But contaminated fingers also could rub an eye or enter a mouth, aiding the chemical’s entry there.
Tell me why I shouldn’t be concerned.
