Like so many persistent chlorinated hydrocarbons, the body's own metabolism cannot detoxify BPA. The next paragraph from the article begins to explain the consequences:
In new research published in the October 4 online issue of the journal PLOS ONE, two scientists at UC San Diego School of Medicine say three-dimensional modeling suggests a metabolite of BPA -- a molecule produced when BPA is metabolized or broken down by the body -- actually binds to the estrogen receptor much more strongly than BPA itself. The finding could point the way to development of a new class of drugs designed to specifically inhibit excessive estrogen activity linked to disease.
Scary stuff. And we (i.e.- society) line our food containers with this stuff, despite having known the gist of these facts since the mid-1990's at least. While the possibility of a new drug might be promising for those in need of its effects, the widespread and common use of BPA means that the whole planet is presently part of an uncontrolled drug experiment.
