the weight of evidence
6 sources for · 0 against

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.

Thayer et al. (2016) found that handling thermal receipt paper is a significant source of occupational exposure to BPA among cashiers.

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.
