Plastic manufacturing chemical BPS harms egg cells, study suggests

FINDINGS Bisphenol S, a chemical used to manufacture polycarbonate water bottles and many other products such as epoxy glues and cash receipts, is an increasingly common replacement for bisphenol A, the use of which was discontinued because of concerns about its harmful effects on the reproductive system. In a new study, UCLA researchers have found that BPS is just as harmful to the reproductive system as the chemical it replaced. BPS damages a woman's eggs and at lower doses than BPA. BACKGROUND. While looking for replacements to toxic chemicals, manufacturers tend to choose substitute chemicals that, while technically different, often share similar physical properties. Due to increasing consumer pressure, companies have replaced BPA with other related compounds now found in many "BPA-free" products. However we do not know how safe these substitutes are.
