BPA/BPS is present at 1-3% by weight on the paper surface and transfers readily to skin on contact — a single receipt provides measurable BPA dermal absorption within seconds. Cashiers handling thermal receipts throughout a workday have significantly elevated urinary BPA levels (2-6x general population). BPA is an established endocrine disruptor (estrogenic activity). BPS, marketed as the 'BPA-free' replacement, shows comparable endocrine-disrupting activity.","synthesis":{"derived_risk_level":"low","synthesis_confidence":0.5,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":1.15,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":2,"compounds_total":2,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
