Bisphenols A (BPA) and S (BPS) 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.
