We’ve always known that BPA’s are bad, or at least some of us have. Now there is even more evidence backing us up.

A new study that had subjects handle store receipts showed BPA absorbed through the skin stays in the body much longer than ingested BPA. The study had subjects handle common store receipts for five minutes, then wear gloves for two hours before washing their hands.

BPA measurements in the subjects’ urine showed BPA levels highest for the first TWO DAYS after handling the receipts. And remember, they only handled the receipt for 5 minutes.

After one week, three of the six volunteers still showed BPA in their urine. Some studies show that the half life of BPA in the body is about 6 hours, but the half life isn’t a linear progression. It actually shows that the half life slows down and doesn’t get detoxed as fast.

Anyway, when the subjects ate a cookie with BPA, follow up urinalysis showed BPA levels spiked after five hours but was cleared after a day. The scientists concluded that the body can more quickly metabolize and clear ingested BPA than BPA absorbed through the skin. If you are looking on the bright side of things, I guess you can take this to mean that its better to use plastic to eat and drink out of than to touch it. BUT NOT REALLY!!

BPA toxicity in everyday food and beverages
BPA (bisphenol-A) is the main component of polycarbonate and is found in water and beverage bottles, plastic lids, the lining of tin cans, food storage containers, dental sealants, contact lenses, and electronics.

Store receipts aren’t the only place people come in contact with BPA. Canned foods often contain significant amounts of the chemical — the lining in a soup can can deliver 1,000 percent more BPA than fresh soup.

Plastics beverage bottles are another common source of exposure, especially if the bottle has been exposed to heat, light, or acids (such as soda).

Plastic food containers, especially if they have been heated (like in a microwave or in a hot car), are another common source. Plastic coffee lids, straws, and any other plastics that come in contact with foods deliver BPA as well. And again, if those foods or liquids are exposed to heat (coffee) you are more likely to absorb increased amounts of BPA.

BPA on store receipts

Store receipts aren’t the only source of BPA that can be absorbed through the skin. Other sources of thermal paper that contains high amounts of BPA include fast food receipts, ATM receipts, airline tickets, gas station receipts, lottery tickets, fax paper (if anyone still uses that), etc.

So ask the cashier to toss the receipt for you. Or, if they have the ability like in my office, just have them email or text the receipt to you. That way you don’t have to touch it and you won’t ever lose it.
