Health effects
Bisphenols A (BPA), F (BPF) 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
Half-life (symbol ) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable at ...
