BAD TRADE  In trying to swap out the potentially toxic compound BPA in their products, manufacturers may be using chemicals that are just as bad, researchers found this year.

A popular alternative to bisphenol A isn’t as benign as people had thought, at least not in lab animals.

After a growing body of research identified hormone-mimicking effects from BPA — a compound found in some plastics, dental sealants and cash register receipts — consumers began reaching for BPA-free products. But there is now evidence that at least one of the chemical substitutes, bisphenol S, can enter the body and trigger developmental and physiological changes.
