Almost all commercially available plastic products we sampled, independent of the type of resin, product, or retail source, leached chemicals having reliably-detectable EA, including those advertised as BPA-free. In some cases, BPA-free products released chemicals having more EA [endocrine activity] than BPA-containing products.BPA is particularly worrisome simply because it is so common. Nearly every American has some amount of BPA in his or her body, in part because plastics are so ubiquitous. (And the U.S. seems to be especially contaminated — a recent study found that Americans have twice as much BPA in their bodies as Canadians.) The Food and Drug Administration expressed 'some concerns' last year about the potential impact of BPA on the brains of fetuses, infants and children — but no federal agency has yet said that BPA or any other potentially endocrine-disrupting chemicals are unsafe."
