Paper money worldwide contains bisphenol A

Paper money worldwide contains bisphenol A: "The cash register receipts that people place near paper money in billfolds and pockets has led to a worldwide contamination of paper money with bisphenol A (BPA) -- a potentially toxic substance. The amounts of BPA on currencies are higher than in dust, but human intake from currency is at least 10 times less than that from house dust, according to a new study."
