BPA transfers to skin on contact: measurable blood BPA increase within 2 hours of handling receipts, enhanced 10x by hand sanitizer or wet/greasy hands. Cashiers and retail workers: urinary BPA 30% higher than general population. BPA → BPS substitution ('BPA-free' thermal paper): BPS has similar estrogenic activity and dermal absorption — not a meaningful safety improvement.
