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.
Bisphenol F (BPF; 4,4′-dihydroxydiphenylmethane) is an organic compound with the chemical formula (HOC 6 H 4) 2 CH 2.It is structurally related to bisphenol A (BPA), a popular precursor for forming plastics, as both belong to the category of molecules known as bisphenols, which feature two phenol groups connected via a linking group.
BPA has been found to interact with a diverse range of hormone receptors, in both humans and animals. [78] It binds to both of the nuclear estrogen receptors (ERs), ERα and ERβ. BPA is a selective estrogen receptor modulator (SERM), or partial agonist of the ER, so it can serve as both an estrogen agonist and antagonist.
It can hurt you, the other person and the relationship.
The leaching of BPA from polycarbonate can also occur at environmental temperature and normal pH (in landfills).The amount of leaching increases as the polycarbonate parts get older. A study found that the decomposition of BPA in landfills (under anaerobic conditions) will not occur. [35] It will therefore be persistent in landfills.
Apple has been offering free engraving on the iPod for a while now, and just in time for the holiday season is rolling out free iPad engraving if they were purchased at Apple.com.
BPA Free Plastic. BPS is used in curing fast-drying epoxy glues and as a corrosion inhibitor.It is also commonly used as a reactant in polymer reactions.. BPS has become increasingly common as a building block in polyethersulfone and some epoxies, following the public awareness that BPA has estrogen-mimicking properties, and widespread-belief that enough of it remains in the products to be ...
"Some people have said to me that they didn't feel like [the person they were texting with] was wanting the response," she explains. "They felt like, 'Well, we're going to meet up on Saturday, so ...
