Would you like a receipt with that?
Well, maybe not.
A study finds that when store receipts contain the hormone-altering chemical BPA it can pass on thru the skin.
BPA is typically used in plastics and the lining of canned goods but it also coats many receipts issued at supermarkets and gas stations.
Of course, it's cashiers rather than customers who are most affected, since cashiers handle receipts throughout each day.
BPA is linked to reproductive issues, cardiovascular disease and cancer.
But we still have little information about exposure to BPA or what levels cause harm.
The study, 24 volunteers handled receipts for two hours.
The contact led to significant upticks in urine BPA levels.
That's compared with baseline data and with a control group who wore gloves when handling the receipts.
The study is in The Journal of the American Medical Association.
The peak levels of BPA in the urine of receipt handlers were still lower than from people after they ate soup from cans with BPA linings.
But this study shows we're absorbing BPA from a variety of sources.
Maybe they can email me my receipt.
Thanks for the minute, for Scientific American 60-Second Health. I'm Dina Fine Maron.
