Bisphenol A (BPA) – Get the Patch

You don’t need to drink from polycarbonate plastic bottles or eat canned food anymore to get your daily dose of bisphenol A.

BPA is commonly used in food and drink packaging, where the molecule is usually locked in as part of a complex polymer. However, concerns have also been raised over its presence in the thermal paper used mainly in till receipts. In thermal paper the compound exists as a free monomer, which makes it easier for the body to absorb than other forms found in food packaging

.

BPA is efficiently absorbed by human skin:

experiments with viable skin models unequivocally demonstrate that BPA is readily absorbed and metabolized by the skin. The trans-dermal route is expected to contribute substantially to BPA exposure in human, when direct contact with BPA (free monomer) occurs

Cashiers had higher levels of BPA than the general population

By occupation, cashiers had the highest BPA concentrations (GM: 2.8 μg/g). Consuming canned vegetables at least once a day was associated with higher BPA concentrations (GM: 2.3 μg/g) compared to those consuming no canned vegetables (GM: 1.6 μg/g). BPA concentrations did not vary by consumption of fresh fruits and vegetables, canned fruit, or store-bough fresh and frozen fish.
