“Chronic disease in human populations is not something traditional toxicology is designed to handle. It doesn’t look for risk factors,” Zoeller said.
In addition, the biologists say BPA, like other hormones, seems to have effects at low doses that don’t occur at high doses. That doesn’t happen with the other chemicals that toxicologists are accustomed to.
While they readily acknowledge data gaps, they maintain that existing evidence strongly suggests that BPA is capable of affecting health at exceptionally low levels of exposure.
“How long do we have to see the same things repeated in studies until we say these effects are real?” Zoeller asked.
