Cashiers absorb significant BPA through skin contact with receipt paper

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Cashiers absorb significant BPA through skin contact with receipt paper?

Yes. Multiple human biomonitoring and toxicological studies confirm that cashiers absorb significant amounts of Bisphenol A (BPA) through dermal contact with thermal receipt paper during their shifts.

Verdict: SUPPORTED · 6 sources for, 0 against · Last checked

The analysis

The claim is supported by a large body of literature, including biomonitoring studies of cashiers showing elevated post-shift urinary BPA levels, intervention studies demonstrating that gloves prevent this rise, and ex vivo / pharmacokinetic studies confirming percutaneous absorption of BPA from thermal paper.
