Bisphenol

Not to be confused with biphenol.

The bisphenols (/ˈbɪsfɪnɒl/) are a group of industrial chemical compounds related to diphenylmethane; commonly used in the creation of plastics and epoxy resins.^[1][2][3] Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter following denotes the variant, which depends on the additional substituents. Bisphenol A is the most popular representative of the group, with millions of metric tons produced globally in the past decade, often simply called "bisphenol".^[3][4][5]

Health effects

Bisphenols A (BPA), F (BPF) and S (BPS) have been shown to be endocrine disruptors, potentially relating to adverse health effects.^[3][6] Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical,^[7] leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life.^[8]
