Like BPA, BPS can be found in a range of paper and plastic consumer products, but theres little evidence that its any safer.
It’s no secret that bisphenol A (BPA) has been linked to health concerns in Canada. What may not be on everyone’s radar, however, is that what’s being used as a substitute may also be causing us harm.
Bisphenol S (BPS) is closely related to BPA in that it has a very similar chemical structure. It is also an endocrine disruptor and may be more environmentally persistent. Little is known about BPS occurrence in the environment, and there is little proof that the synthetic compound is a better substitute for BPA.
A new report in the journal Environmental Science & Technology is believed to be the first to analyze the occurrences of BPS in thermal and recycled paper and paper currencies. Researchers analyzed 16 types of paper from the US, Japan, Korea, and Vietnam.
According to the study’s press release, BPS was found in all of the receipt paper they tested, 87 percent of sampled paper currency, and 52 percent of recycled paper.
The researchers estimate that BPS is being absorbed 19 times more than when BPA was more widely used. People who handle thermal paper regularly at work could be absorbing much more.
BPA, BPS’s predecessor, has been linked to breast and prostate cancer, neurobehavioural abnormalities, and increased risk of obesity and heart disease. It’s been found not only in hard plastics used in products such as food containers, sports equipment, and car parts, but also in a large number of paper products, including:
