BPA (Bisphenol A)
Bisphenol A is an endocrine disruptor, but I collected this links seperately, because this is the chemical, which is produced in the largest quantities worldwide. It was synthesized in 1891 for the first time. In the 1930's, its estrogenic properties were discovered but deemed to weak for an artificial hormone. In the 40's some idiot polymerized it to polycarbonate which leaches and degrades to BPA. The estrogenic properies were denied for a long time and the lobby still calls it safe. It is already banned e.g. for baby bottles in several countries. It is ubiquitous however. Sometimes it's replaced by BPS, which may be even a much worse endocrine Disruptor.BPA is often wrongly referred as plastisizer or "Weichmacher" in German. That's wrong, it is hard and this also wrongly suggests to be an additive only. It is the substance itself. Beside that, the presence of BPA is more important than the dose. Endocrine receptors react to few ppb. They even look insensitive to very hight doses. So the industry may always prove BPA's non-toxicity with rather hight doses. BPA also challenges the Paracelsus paradigm. It is not the dose wich makes BPA to the poison. It is the long term exposure, even at rather small levels.
Sorry for this prologue, but you see, this stuff is a tough political issue.

Pregnant women who eat canned vegetables daily have elevated levels of bisphenol A, an estrogenic chemical found in food containers and other consumer products, according to new research published today. More than 90 percent of pregnant women had detectable levels of BPA, and a variety of sources of the chemical were identified in the study. Pregnant women who were exposed to tobacco smoke or worked as cashiers also had above-average concentrations.

BPA replacement alters hormones at low doses, study finds — Environmental Health News
Just like the controversial compound it's designed to replace, a chemical used in cash register receipts and other consumer products messes with hormones, according to research published today. The study by University of Texas scientists is the first to link low concentrations of bisphenol S (BPS) -- a bisphenol A (BPA) alternative -- to disruption of estrogen, spurring concern that it might harm human health. Researchers exposed rat cells to levels of BPS that are within the range people are exposed to. And, just like BPA, the compound interfered with how cells respond to natural estrogen, which is vital for reproduction and other functions. “I think we should all stop and be very cautious about just accepting this as a substitute for BPA,” said lead author and biochemist Cheryl Watson. “And not just BPS. We should question the whole process about how we introduce chemicals into the marketplace without properly testing them first.”
Timeline: BPA from Invention to Phase-Out | Environmental Working Group
BPA was invented nearly 120 years ago and currently used in enormous amounts to manufacture hard plastic water bottles and to make epoxy linings of metal food cans, like those for canned infant formula. Stuides conducted over the past 20 years now show it to be not only a ubiquitous pollutant in the human body - it contaminates nearly 93% of the population - but also a potent developmental toxin at very low doses.

Mice harmed by low doses of BPA but not high doses, study says — Environmental Health News
Baby mice exposed in the womb to low doses – but not high doses – of bisphenol A were fatter and had metabolic changes linked to obesity and diabetes, according to a new study published today. Building on previous studies that link the hormone-altering chemical to changes in body weight and glucose tolerance, the new research fuels an ongoing controversy over whether federal testing of chemicals is adequate to protect people from low doses. “What’s scary is that we found effects at levels that the government not only says is safe, but that they don’t bother to test,” said Fredrick vom Saal, a University of Missouri, Columbia, professor and senior author of the study. Many of the effects were reported in the mice fed daily doses – just during pregnancy – that were one-tenth of the amount that the U.S. Environmental Protection Agency says is safe for daily exposure throughout life. Used in polycarbonate plastics, canned food liners and some thermal receipts, BPA is found in almost everyone’s body. Some earlier studies have linked it to obesity and diabetes in people.

Researchers at the University of Missouri have used biparental California mice to prove that offspring born to parents who are exposed to BPA receive decreased parental care by both the mother and father.
