Health and Environmental Concerns
Some thermal papers are coated with BPA, a chemical considered to be an endocrine disruptor. This material can contaminate recycled paper. BPA can transfer readily to the skin in small amounts:
When taking hold of a receipt consisting of thermal printing paper for five seconds, roughly 1 μg BPA (0.2–0.6 μg) was transferred to the forefinger and the middle finger if the skin was rather dry, and about ten times more than this if these fingers were wet or very greasy. Exposure to a person who repeatedly touches thermal printer paper for about ten hours per day, such as at a cash register, could reach 71 micrograms per day, which is 42 times less than the present tolerable daily intake (TDI).Read more about this topic: Thermal Paper
Famous quotes containing the words health and, health and/or concerns:
“Pride can go without domestics, without fine clothes, can live in a house with two rooms, can eat potato, purslain, beans, lyed corn, can work on the soil, can travel afoot, can talk with poor men, or sit silent well contented with fine saloons. But vanity costs money, labor, horses, men, women, health and peace, and is still nothing at last; a long way leading nowhere.—Only one drawback; proud people are intolerably selfish, and the vain are gentle and giving.”
—Ralph Waldo Emerson (1803–1882)

“I have no doubt that it was a principle they fought for, as much as our ancestors, and not to avoid a three-penny tax on their tea; and the results of this battle will be as important and memorable to those whom it concerns as those of the battle of Bunker Hill, at least.”
—Henry David Thoreau (1817–1862)
