Transfer of bisphenol A from thermal printer paper to the skin

  journal={Analytical and Bioanalytical Chemistry},
AbstractOf 13 thermal printing papers analyzed, 11 contained 8–17 g/kg bisphenol A (BPA). When taking hold of a receipt consisting of thermal printing paper for 5 s, roughly 1 μg BPA (0.2–6 μg) was transferred to the forefinger and the middle finger if the skin was rather dry and about ten times more if these fingers were wet or very greasy. This amount transferred to dry skin was neither significantly increased when taking hold of the paper at up to 10 sites, nor reduced when BPA-free paper… 
Skin Absorption of Bisphenol A and Its Alternatives in Thermal Paper.
The necessary data is provided here to estimate the extent of skin absorption of BPA analogues, which is a necessary step in risk assessment, and ultimately evaluate public health risks posed by D-8, BPS, and PF201.
Migration of pseudoestrogen bisphenol A from various types of paper with thermochromic prints to artificial sweat solutions
Abstract Thermochromic inks, materials that change color at a certain temperature, are increasingly used on papers and other materials in the areas of design, commercials, and security printing.

Elimination of Estrogenic Activity of Thermal Paper Using Laccase from Trichoderma sp NFCCI-2745
Waste thermal paper used at the local automated teller machine counters of India is proposed as a cheap substrate for laccase production for a safer and cleaner environment and the results indicate that these papers can produce estrogen hormone-like effect on experimental systems.
High levels of bisphenol A in paper currencies from several countries, and implications for dermal exposure.
The sources of human exposure to bisphenol A (BPA) are not well characterized. Little is known about the presence of BPA in paper products, especially in paper currencies, and its implications for
High Levels of Bisphenol A and Bisphenol S in Brazilian Thermal Paper Receipts and Estimation of Daily Exposure
The aim of the present study was to determine levels of BPA and BPS in 190 different thermal receipts, randomly collected from different locations in São Paulo State, Brazil, including receipts from supermarkets, general and fast-food restaurants, gas stations, bus and airplane tickets, and credit card and bank accounts.
Bisphenol A and its structural analogues in household waste paper.

Release of bisphenol A from polycarbonate baby bottles: mechanisms of formation and investigation of worst case scenarios
The question was further investigated whether there could be conditions resulting in contamination of beverages in polycarbonate bottles for babies with bisphenol A (BPA) at concentrations causing
Cutaneous Penetration of Bisphenol A in Pig Skin
In vitro cutaneous penetration of BPA through pig skin, using a Franz cell, showed BPA remained essentially on the skin surface and penetration mainly accumulated in the dermis, which may be reassuring for workers in contact with BPA-based products.
Application of deuterated compounds for investigations of percutaneous absorption of chemical substances.
The percutaneous absorption of the xenoestrogen 2,2-bis-(4-hydroxyphenyl)-propane (bisphenol A) 1 has been studied and compared with results on dibenzoyl peroxide 2, a component of drug formulations for topical application to confirm a possible penetration of 1 from the environment through the skin into the capillary system.
NTP-CERHR monograph on the potential human reproductive and developmental effects of bisphenol A.
The National Toxicology Program (NTP) Center for the Evaluation of Risks to Human Reproduction (CERHR) conducted an evaluation of the potential for bisphenol A to cause adverse effects on
Why Public Health Agencies Cannot Depend on Good Laboratory Practices as a Criterion for Selecting Data: The Case of Bisphenol A
Differences between industry-funded GLP studies of BPA conducted by commercial laboratories for regulatory purposes and non-GLP studies conducted in academic and government laboratories are reviewed to identify hazards and molecular mechanisms mediating adverse effects.
