Here's an excerpt from the Globe and Mail article, 'Inherently toxic' chemical faces its future,
It seems obvious that a high dose of a poison would be more dangerous than a lower one, but bisphenol A is creating a stir because it doesn't follow this seemingly common-sense rule. Researchers say this oddity results from the fact that bisphenol A isn't a conventional harmful agent, such as cigarette smoke, but behaves in the unconventional way typical of hormones, where even vanishingly small exposures can be harmful.Look for this issue to gain increasing public attention over the coming months and years.
This is why some environmentalists and scientists contend that bisphenol A, which leaches in trace amounts from food and beverage packaging, is among the scariest manufactured substances in use, an eerie modern version of the vaunted lead water pipes by which ancient Romans were unknowingly poisoned.
Extrapolating from the results of animal experiments, they suspect bisphenol A has its fingerprints all over the unexplained human health trends emerging in recent decades hinting at something going haywire with sex hormones, including the early onset of puberty, declining sperm counts, and the huge increase in breast and prostate cancer, among other ailments.
