It would have been hard to get through 2010 without bumping into some scary information about the plastic ingredient bisphenol A, aka BPA, like the fact it leaches from polycarbonate baby bottles & sports bottles and metal food can linings into the contents or that it is widespread in the dye on thermal cash register receipts and is absorbed through human skin.
Adding to such anxieties about environmental toxins, Japanese researchers have recently honed in on a chemical very similar to BPA dubbed BPAF, or bisphenol AF, that might be even more dangerous than BPA. The “F” stands for fluorine, and the two substances are identical except for the substitution of six fluorine atoms in BPAF for six hydrogens in BPA (see below).
In part, it was knowledge that certain properties of fluorine might intensify the molecule’s reactivity that drew the researchers’ attention to BPAF, as there are additional chemicals out there that resemble BPA too.
The risks of exposure to BPA stem from the fact that it is an endocrine disruptor that mimics the actions of the hormone estrogen. Over 200 laboratory studies have linked low-dose BPA exposure to a host of health effects including reduced sperm production and infertility, cardiovascular diseae, diabetes and derailed development of the brain and prostate gland.
