It seems that chemical bisphenol A (BPA) has triggered another controversy. It has come to light that paper money being used worldwide is contaminated with BPA. Published in the journal Environmental Science & Technology, the study examined 156 pieces of paper money from 21 countries and got to know that paper money from Brazil, the Czech Republic and Australia has highest level of BPA while that from Philippines, Thailand and Vietnam, traces of BPA were low.

The shocking fact is that the traces found on dollars, Euros, rubles, Yuan and other currencies were a lot higher that being identified in house dust, though its impact on human health gradually gets reduced by at least 10 times.

The questioned chemical substance is reported to have been used in making of polycarbonate plastics used in some consumer products, including water bottles, sports equipment, and household electronics.

The researcher Dr. Kurunthachalam Kannan along with his team at the State University of New York has observed that when a money receipt is being pushed to the wallet, BPA is subsequently moved to any other paper in the wallet.

Nonetheless, the impact of human health is paltry; risk of excessive exposure to BPA cannot be overlooked for a long time.
