Washington, the threat of poison materials in plastic material, known as BPA (Bisphenol-A) continues. If the first is aware of only a bottle of milk and beverage bottles, BPA is also now the threat contained in the receipt of payment.

A recent study found that the receipt contain levels of bisphenol A (BPA) is high. In this latest research only on receipt paper in the American state, but suspected in other countries were not much different.

The team from the U.S. tested the receipt of payment which is made of thermal paper collected from 22 shopping centers and cafes in the United States. Researchers found half of the paper contains BPA levels in large numbers. BPA is used to make the ink to be visible in thermal receipt.

Chemicals that resemble the female hormone estrogen is known to pose a risk to health, especially for young children.

If someone is holding the paper for 10 seconds, then it will move 2.5 micrograms of BPA from paper to a person’s finger. Whereas if you rubbed it will increase the amount of BPA that migrate into fingers about 15 times as much.

The researcher disclosed that since the CPA was found in a layer of flour on thermal paper, scientists have found BPA in the womb also in other objects. BPA is widely used in plastic water bottles, soft drink cans, cases of cell phones and computers as well.

While researchers from the Washington Toxics Coalition and Safer Chemicals found chemicals in the 21-22 paper bills tested, although its content in a much lower level than the receipt of payment.

More than 130 studies over the past decade shows that high levels of BPA linked to serious health problems, including breast cancer, obesity and early puberty.

In November 2010, the European Union has provided ban use of BPA in baby bottles.Because results from animal studies showed the test substance affects the neurological development and behavior of laboratory rats when exposed to BPA while still in the womb or in early life. While the first country to ban use of BPA is Canadian.

While the World Health Organization (WHO) found an association between exposure to BPA is low with adverse health problems.

WHO researchers found levels of BPA found in urine a person has relatively the same levels of BPA that enter the body. This means that most or perhaps even all of them can be excreted or removed from the body naturally.

“It required a strong legal rules regarding the use of these chemicals in the receipt of payment, billing, and many other products,” said Andy Igrejas, director of Safer Chemicals,Monday (12/13/2010).
