"Just like the controversial compound it's designed to replace, a chemical used in cash register receipts and other consumer products messes with hormones, according to research published today."
"The study by University of Texas scientists is the first to link low concentrations of bisphenol S (BPS) -- a bisphenol A (BPA) alternative -- to disruption of estrogen, spurring concern that it might harm human health. Researchers exposed rat cells to levels of BPS that are within the range people are exposed to. And, just like BPA, the compound interfered with how cells respond to natural estrogen, which is vital for reproduction and other functions. 'I think we should all stop and be very cautious about just accepting this as a substitute for BPA,' said lead author and biochemist Cheryl Watson. 'And not just BPS. We should question the whole process about how we introduce chemicals into the marketplace without properly testing them first.'"
