Large-scale study in the U.S. showed that virtually all dollar bills are different concentrations of bisphenol A. This chemical compound is detected by at least half termochekov — those labels that are printed on electronic scales in the produce section of supermarkets. Nine out of ten notes (the study banknotes from $ 1 to $ 100) contain low doses of organic carcinogen bisphenol A. In this twentieth of all paper money in the U.S. is the concentration of bisphenol A, which experts call dangerous.
Bisphenol A in 2010 was officially recognized by the U.S. toxic organic compound. This chemical compound is present in all dental restorative composite materials. Under the effect of the saliva it may enter the bloodstream. Experts say that harmful even trace amounts of bisphenol A.
This material is structurally similar to the female sex hormone estrogen. Due to this, bisphenol A can "replace" estrogen in the body — receptors of various organs perceive it "as its own." This effect turns serious consequences. Bisphenol A is one of the factors causing cancer: cancer of the prostate, testes, breast cancer in women and in men. In addition, the effect of the component associated with the development of mutations in the sperm DNA, inhibition of reproductive function, metabolism disorders — obesity and diabetes.
Official recognition of bisphenol A as dangerous to human health and life component, the researchers sought for many years. Previously, this substance was found in various types of plastics, including those which produce children of dishes. As for paper bills, the researchers believe that bisphenol A with dollars, covered by its powdery composition is ingested mainly by folding or creasing.
Bisphenol A is dangerous in that heating or prolonged storage of food in a plastic container it can move in the food itself. The first country to draw attention to the danger of bisphenol A was Canada. There, in 2008, banned baby bottles from materials containing bisphenol A — those on the market for more than 90%. In 2010, Canadian health authorities have declared BPA a toxic substance. In the same year, the WHO declared that the component is not unconditional carcinogen. However, two weeks after the European Commission issued a statement of a decree banning of plastic infant feeding bottles containing bisphenol A.
