BPA: Low Doses Are Poisonous, Too

In the wake of the Sigg/bisphenol-A controversy, a top researcher and CEO of Environmental Health Sciences fills us in on the news: endocrine disruptors such as BPA and phthalates are indeed toxic at low-level doses, too. And they’re toxic in entirely different ways than at the traditional high-dose testing indicates.

The way the tests work today is we think that by testing at high doses we’re gonna see everything. So that once we get to a dose that’s intermediate and we don’t see anything, we’re golden.

But the science is telling us that at really low doses as contaminants mimic hormones. They can have effects that are totally unpredictable by what happens at high doses.

Pete Myers spoke to Living on Earth about the consequences of current testing.
