How big is the world production of bisphenol A?

World production capacity of Bisphenol A was 1 million tons in the 1980s, and more than 2.2 million tons in 2009. It is a high production volume chemical.

How is bisphenol A diglycidyl ether metabolized?

Bisphenol A diglycidyl ether is rapidly metabolized in mice, the major route involving hydration to the corresponding bis-diol, which occurs both enzymatically, through the epoxide hydrolase, and nonenzymatically. This hydration is followed by monooxygenase-mediated dealkylation to form a phenol and glyceraldehyde.
