Blank Cash Receipt

There is a flood BPA-free products. These assorted water bottles and food containers have surged to market prompted by a fear that bisphenol A (BPA) used in making some types of plastic bottles and coatings can leach out to be consumed. Now, the same technology that has permitted the detection of illegal drugs contaminating essentially all circulated currency has now been applied to find minute amounts of potentially toxic compounds in food, beverages or water stored in common containers. Recent studies confirmed that behavioral changes occur in children whose mothers had BPA in their blood during the first trimester of gestation. And another major source of environmental BPA has been found in cash register and credit card receipts.

BPA in Polycarbonate Plastics and Plasticizers

Bisphenol A, as the name indicates, consists of two phenol groups linked together. Phenol, also called carbolic acid, was one of the first operating room antiseptics and is still used in the form of Camphophenic. Millions of tons of BPA are produced each for the manufacture of polycarbonate plastics and as an antioxidant in plasticizers to make other plastics less brittle. The vast majority of the BPA that goes into these plastic polymers never comes out again, but if these plastics are repeatedly heated, small amounts of BPA can leach out.

BPA Causes Developmental Changes in Laboratory Animals

The BPA scare came from recognition that BPA was able to interact with animals in the same way as steroid hormones, i.e. BPA has slight estrogen activity. There was evidence in laboratory animals that early development was particularly sensitive to BPA. Subsequent studies showed that many women had BPA levels that were sufficient to cause developmental changes in laboratory animals.
