BPA grabs the headlines, but what about BPS?

Women drinking water

Bisphenol A or BPA is frequently in the news for its danger to humans. BPA is an endocrine disrupter and can act as estrogen leading to evidence of negative health consequences in animal test subjects and health consequences for humans. While there's debate about the effects of BPA in low doses or in containers, many products, from water bottles to receipt paper, are moving to alternatives, like bisphenol S or BPS.

But, as Environmental Health Perspectives explained, BPS also may carry risks. Therefore replacing BPA with BPS may not be solving the problem at all, but rather replacing it with a new one.

BPS concerns

Environmental Health Perspectives pointed to a study from two researchers in the Department of Biochemistry and Molecular Biology at the University of Texas in Galveston as evidence of the risk BPS presents. The study, which used rats as subjects, tested BPS exposure at low levels and looked at cell health. It concluded that BPS led to a disruption in membrane-initiated E2-induced cell signaling and cell proliferation. The rats also experienced cell death.

Studies are being done about BPS, but not few on its health effects. EHP explained that work has only started on the health consequences of BPS while, many researchers have looked at the proliferation of BPS in everyday life. It's in the environment, a variety of consumer goods and even the human body.

Like BPA, BPS is found in a high percentage of the population of the U.S.' urine. EHP explained that researchers found the highest concentrations of BPS in the urine of Japanese citizens, where BPA had been banned in paper products as early as 2000.

BPS, like BPA, is likely absorbed through the skin from paper goods like receipts. This EHP article explained that more research needs to be done to find the full effects of BPS or how it enters the human body, but Laura Vandenberg, a postdoctoral fellow at Tufts University told EHP that she definitely doesn't want BPS to get onto certain consumer paper goods that are made of recycled materials.
