Remember all the fuss over bisphenol A (BPA), the chemical compound used in a wide array of consumer products that was shown to disrupt hormones and cause birth defects? Well, new research by scientists at the University of Texas strongly suggests that the alternative compound designed to replace BPA, bisphenol S (BPS), may have exactly the same effects.
Researchers exposed rats to low levels of BPS, similar to those that humans may encounter, and found that just like with BPA, the compound disturbed the body’s ability to process the hormone estrogen.
Both BPS and BPA are used in everything from hard plastic water bottles to thermal paper used for cash register receipts. Nearly everyone in the world has been exposed at some point. According to a study released last year, 93 percent of Americans have traces of BPA in their urine. Hooray for science.
