1976
Congress passes the Toxic Substances Control Act, the first law in the United States to regulate industrial chemical compounds. BPA is one of 62,000 compounds grandfathered in, presumed safe by the Environmental Protection Agency
1993
The EPA sets a safety standard for BPA based on high-dose studies. This remains the standard, despite studies during the next 15 years linking very low doses to cancer, diabetes, fertility problems and behavioral disorders
1997
Frederick vom Saal at the University of Missouri at Columbia publishes the first study that links low-level BPA exposure to prostate cancer. The "low dose" is 25 times lower than EPA's "safe" dose. Meanwhile, the FDA finds BPA leaching from the epoxy linings of metal cans of baby formula.
