Bisphenol A (BPA), a chemical used in plastic products, is linked to obesity, cancer, infertility, and thyroid problems. Several studies found that it interferes with hormones and their receptors.
The French National Institute for Agricultural Research found that BPA readily passes through the skin. Thermal receipt paper is a significant source of BPA, and cashiers had the highest levels of any occupational group. BPA can’t be seen or smelled, so people have no idea whether they have been exposed to this dangerous chemical.
In September 2010, Canada declared BPA a dangerous environmental toxin and the United States FDA expressed concern about its effect on the brain, behavior, and sexual development in unborn children. BPA is a significant environmental poison that affects hormones controlling reproductive function, appetite, and weight control. The Appleton Paper Company began producing a BPA-free receipt paper in November 2010. (Science News)
