Handling Thermal-Paper Receipts Linked to Increased BPA Levels in Urine
By Joe Elia
Prolonged handling of thermal-activated receipt paper without gloves increases bisphenol A (BPA) levels in urine, according to a research letter in JAMA.
BPA exposure has been associated with reproductive and neurodevelopmental abnormalities.
Volunteers handled the receipts for 2 hours without gloves. Urine specimens were obtained before and after handling. A week later, the same exercise was done — this time, volunteers wore nitrile gloves.
Ungloved handling increased urinary BPA more than threefold over baseline, whereas gloved handling showed no effect on BPA levels.
