The heat-sensitive coating that creates the printed image is typically a developer/dye system containing either BPA or, increasingly, BPS as a color developer. Unlike most BPA exposures (dietary), thermal paper creates a direct dermal route of exposure — skin absorption of BPA/BPS from handling receipts. Cashiers and retail workers who handle receipts throughout the day have measurably higher urinary BPA/BPS levels than the general population.","synthesis":{"derived_risk_level":"low","synthesis_confidence":0.5,"synthesis_method":"compound_composition","context_used":"human_pregnant","context_source":"product_users","exposure_modifier":1.05,"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]).
