Summary:
This is the crux of a vehement debate that is being waged as federal officials are trying to decide whether the chemical, known as BPA, should be regulated. BPA is arguably the most controversial chemical in consumer products. It is used to make polycarbonate plastic as well as food and beverage can liners and some paper receipts and dental sealants. BPA acts like an estrogen, disrupting hormones In laboratory animals. it alters how their reproductive systems and brains develop, and sets the stage for breast and prostate cancer. People with higher levels of exposure have an increased risk of cardiovascular disease, obesity and diabetes, according to some studies. 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.

Reflection:
Chronic disease in human populations is not something traditional toxicology is designed to handle. It doesn’t look for risk factors. 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. I think that BPA harms people with low does of it and we should not use it anymore.
