Thermal paper is a special fine paper that is coated with a chemical that changes color when exposed to heat. It is used in thermal printers and particularly in inexpensive or lightweight devices such as adding machines, cash registers, and credit card terminals.
In the thermal receipts now routinely given out by stores, BPA is often used as a color developer for the printing dye. Such receipts have a thermal-sensitive layer that, when heated, produces color. Beyond cash register receipts, high levels of BPA are also often present in the thermal paper used to make baggage destination tags, cigarette filters, and bus, train and lottery tickets.
A study finds that when store receipts contain the hormone-altering chemical BPA it can pass on thru the skin. BPA is typically used in plastics and the lining of canned goods but it also coats many receipts issued at supermarkets and gas stations.
Of course, it’s cashiers rather than customers who are most affected, since cashiers handle receipts throughout each day.
Human exposure to bisphenol A (BPA) has been associated with adverse health outcomes, including reproductive function in adults1 and neurodevelopment in children exposed perinatally.2 Exposure to BPA is primarily through dietary ingestion, including consumption of canned foods.3 A less-studied source of exposure is thermal receipt paper,4 handled daily by many people at supermarkets, ATM machines, gas stations, and other settings. We hypothesized that handling of thermal receipts significantly increases BPA exposure, but use of gloves during handling minimizes exposure.
Two hours after touching the receipts without gloves, the BPA levels in the participants' urine was significantly elevated, rising from 1.8 micrograms of BPA per liter to 5.8 micrograms per liter.
After 8 hours, the study authors tested some of the gloveless participants again, and found that the BPA levels went up to 11.1 micrograms per liter, an almost five-fold increase.
We now know that thermal receipt paper, used widely every day, is another way that Bisphenol A (BPA) gets into us. Studies have shown cashiers have higher levels of BPA in their body fluids than other occupations. Regular receipt handling may be of particular concern to pregnant women or women of childbearing age and adolescents of both sexes who handle receipts regularly.
BPA is known to be hazardous to human, fish and other animal reproductive systems and has been linked with obesity and attention disorders. The other commonly used chemical for thermal receipts, BPS, has been shown to have some similar effects.

This actually made its way onto the british msm a little while back. But as usual it was presented as "nothing to worry about, move along" and quickly followed by some celebrity nonsense.

I was curious what other effects are blamed on BPA and a google search brought up a lot of sites.
I was disappointed to see that BPA`s are being blamed for everything from tooth decay to heart attacks and everything in between.
It`s hard for me to take things like this seriously when they use a shotgun approach at defining the effects.

Its also concerning in this society of going green that the alternative is an ereciept that can be not only tracked but also manipulated.
