In an article published on February 2, 2016, The Washington Post provides an insider’s view on a recently published scientific study that compared the effects of bisphenol A (BPA, CAS 80-05-7) and bisphenol S (BPS, CAS 80-09-1) on neuroendocrine development of zebrafish embryos (FPF reported). Nancy Wayne, scientist at the University of California, Los Angeles, U.S., and senior author of the study, describes her difficulties with obtaining federal funding to perform research on the endocrine effects of BPS, a common replacement for the controversial substance BPA. The study became possible only when a visiting graduate student from Shanghai University, Wenhui Qiu, brought in the funding from her own government.
According to Wayne, their study clearly shows that, at least in fish, “BPS is not necessarily safer” than BPA. To better understand the relevance of this study’s findings for humans, more research is urgently needed; Wayne hopes that “the endocrine community will pick it up and take it forward.”
