Holding the receipts for 10 seconds absorbs enough bisphenol S to break California’s safety rule, research finds

Paper receipts from major retailers in the US are so laden with bisphenol S that holding one for 10 seconds can cause the skin to absorb enough of the highly toxic chemical to violate California’s safety threshold, new research has found.

The findings are being used as evidence in legal action aimed at pressuring retailers to stop using receipt paper treated with bisphenol S, or BPS, which is linked to cancer and reproductive problems.

The Center for Environmental Health (CEH) non-profit has sent violation notices to about 50 major retailers alerting them to the exceedance of California’s Proposition 65 limits for BPS.
