Paper money not only can have a whole colony of microbes on its surface, but also contain a dangerous substance - bisphenol-A, a chemical compound similar to estrogen. Recall, previously Canada declared him outlawed, writes The Globe and Mail.

This discovery was made by American scientists from the Washington Toxics Coalition and Healthy Families Coalition. They tested 22 banknotes and found the content of bisphenol in 21 of them. Experts believe that the substance could get on money from contact with the cashier's check.

In order to test this theory, the scientists also checked the checks themselves. It turned out that half of them were covered with bisphenol, sometimes in huge quantities. It turns out, it's the checks that are to blame. Notably: until recently, experts believed that bisphenol enters the body through water bottles and food cans, but the new study expands the number of dangerous items.

Bisphenol is very easily transferred to the hands. And the concentration of the chemical compound on the banknotes is several times greater than the concentration in plastic products. Scientists advise washing their hands after they have touched a check or banknotes. To give the same things to children is strictly not recommended.
