More Evidence That BPA Laces Store Receipts

Science & the Public Blog: Problem is, you can’t tell which ones host the hormone mimic
People interested in limiting exposure to bisphenol A — a hormone-mimicking environmental contaminant — might want to consider wearing gloves the next time a store clerk hands over a cash-register receipt. A July 27 report by a public-interest research group has now confirmed many of these receipts have a BPA-rich powdery residue on their surface. But you can’t tell which ones on the basis of a visual inspection.
A building block of polycarbonate plastics, bisphenol A is also a biologically active estrogen mimic. Less well known, many thermal- and carbonless-copy papers also employ BPA to print images, generally store receipts.
In animals, fetal exposures to BPA can be especially risky, sometimes fostering brain, behavioral or reproductive problems. Canada and some states are moving to ban polycarbonate plastic in baby bottles for that reason. And heart data suggest that even adult exposures to BPA might cause harm.
A vexing question has been where people are acquiring the BPA that taints nearly everyone’s body. Last year, green chemist John Warner argued that his data suggested store receipts could be a — if not the — leading source.

If we don't change our ways soon...
A new report by the Royal Society, chaired by Nobel prize-winning biologist Sir John Sulston warns that world population must be stabilized and consumption in wealthy nations must be reduced or the entire planet is in big trouble. As the report reads: "The number of people living on the planet has never been higher, their levels of consumption are unprecedented and vast changes are taking place in the environment. We can choose to rebalance the use of resources to a more egalitarian pattern of consumption... or we can choose to do nothing and to drift into a downward spiral of economic and environmental ills leading to a more unequal and inhospitable future."This is the same warning that President Jimmy Carter gave Americans back in the 1970's - but it was ignored when Ronald Reagan came to power with a "more positive" message basically telling Americans we can do whatever we want. And then after 9/11 - Bush told us all we should go shopping and consume ever more.And now with corporations calling the shots in Washington - long-term sustainability of the planet takes a back seat to short-term profits. If we don't change our ways soon - and embrace clean, alternative energy and educate women around the plant - then we all could be headed for a rough century.-Thom(Is there any chance we will learn in time?
