After years of campaigning, health advocates finally convinced many household product manufacturers to remove the chemical Bisphenol A, known as BPA, from items like receipts, plastic bottles and the lining of tin cans. And as a result, it's not hard to find products labeled "BPA Free." But it turns out the chemicals used to replace BPA may have nearly the exact impact on the human body—hormone disruption—as BPA, according to a new study. "We've got to do something about putting brand new compounds in products without having consulted with biologists about what they do," said UTMB professor, Cheryl Watson. The news also appears in MSN.
