BAD TRADE  Manufacturers may have ditched using the potentially toxic chemical BPA (bisphenol A) in common products such as receipts and plastic bottles in favor of an equally toxic relative, bisphenol S, new research suggests.

Chemical tweaks aren’t enough to tame a possibly dangerous component of plastics, several new studies suggest. 

Bisphenol S, or BPS, a common chemical in everyday plastics and papers, has the same toxic, hormone-disrupting effects in cells and animals as its older relative, bisphenol A, or BPA. The findings are the latest to raise doubts that BPS – or perhaps any other bisphenols – are a safer alternative to BPA. The studies also suggest that products labeled “BPA-free,” such as baby bottles, are not as free of health risks as consumers might expect.

In a study published February 26 in Environmental Health Perspectives, researchers found that BPS, like BPA, can boost heart rates and spur irregular heartbeats in female rats. In the Feb. 3 Proceedings of the National Academy of
