BPA Substitute Lurks in Paper Money, Receipts

THURSDAY, July 12 (HealthDay News) — Many people are absorbing high
levels of bisphenol S — a substitute for the chemical compound bisphenol
A — when they handle cash register receipts and other types of paper,
researchers say.

Bisphenol A (BPA), which is used to make plastics and epoxy resins, has
been declared a toxic substance by the Canadian government, and has been
banned by 11 states in the United States for use in baby bottles and
children’s sippy cups. The U.S. Food and Drug Administration, however, has
not made such a distinction.

Concerns about the health effects of BPA have led some manufacturers to
replace it with bisphenol S (BPS), which is closely related to BPA and has
some of the same estrogen-mimicking effects, the authors explained in the
study published in a recent issue of the journal Environmental Science
Technology
.

But there are unanswered questions about whether BPS is safer than BPA,
the researchers noted in a journal news release.

For the study, the investigators analyzed 16 types of thermal
cash-register paper, recycled paper and paper currency from the United
States, Japan, Korea and Vietnam. They detected BPS on all the receipt
paper, 87 percent of the paper currency and 52 percent of the recycled
paper.

Compared with when BPA was more widely used, people may now be
absorbing 19 times more BPS through their skin, and people who handle
thermal cash-register paper in their jobs may be absorbing even more BPS,
said Kurunthachalam Kannan, a research scientist at the New York State
Department of Health, and colleagues.
