This call introduced a newly published systematic review by Johanna Rochester and Ashley Bolden that synthesizes the literature on the endocrine disruptive effects of bisphenol S (BPS) and bisphenol F (BPF), and compares their potency to that of bisphenol A (BPA). BPA is a well-studied endocrine disrupting chemical found in many everyday products, including plastics and cash register receipts. BPA has been shown to have disruptive effects in animals and has been linked to disease and disorders in humans.
Increasing concern by the general population has prompted the substitution of BPA for other chemicals. However, many of these other chemicals are also bisphenols, closely related to BPA. BPS and BPF are two such BPA substitutes that are being used, sometimes in products labeled “BPA-free.” Dr. Rochester presented the current literature on BPS and BPF and discussed their safety as BPA replacements.
Dr. Rochester is a Research Associate at TEDX, The Endocrine Disruption Exchange. She received her BS, MS, and PhD from the University of California, Davis, where she studied the effects of natural and man-made environmental estrogens on wild birds. As a postdoctoral fellow at the University of Colorado, Boulder, Dr. Rochester studied how reproductive brain hormones are maintained in adult mammals, and the implications for human reproductive health. Her recent work has included using systematic review to assess the hazards of environmental chemicals on human health. In particular, she is working on the Prenatal Origins of Adult Disease/Disorders/Syndromes (PODS) project, developed by TEDX. This project identifies the effects of early chemical exposure on the development of later life diseases. She has also recently published a review article on the effects of bisphenol A in humans.
This half-hour teleconference call is one in a monthly series sponsored by the Collaborative on Health and the Environment’s EDC Strategies Group.The CHE EDC Strategies Group is chaired by Carol Kwiatkowski (TEDX), Sharyle Patton (Commonweal), and Genon Jensen (HEAL).

The call was moderated by Carol Kwiatkowski, PhD, Executive Director of TEDX.
