Bisphenol
The bisphenols are a group of chemical compounds with two hydroxyphenyl functionalities. Most of them are based on diphenylmethane. The exceptions are bisphenol S, P, and M. "Bisphenol" is a common name; the letter following refers to one of the reactants. Bisphenol A is the most popular representative of this group, often simply called "bisphenol."List
Bisphenols A and S have been shown to be endocrine disruptors. Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical, leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life.
