aspirin in large dose is fatal too.

The question that begs then, is BPA toxicity cumulative like heavy metal poisoning or does the body manage to heal itself before the next round of low level exposure?

sometimes trying to study events at or near the limits of reliable detection leads to junk science. Cold fusion is a good example.

so thank you for your perspective. I really wonder at times of "accelerated life testing" or other testing methods and extrapolating down. It makes me cringe.
