BPA has been reduced in use over the past 15 years, but it has been replaced by other bisphenols like BPS and BPF whose safety relative to BPA is unclear.

“ironically um the presence of BPA at least uh being used actively uh has been reduced quite a bit over the past 15 years but just understand that there's a whole family of these uh bisphenols and typically we substitute one for the other um but what are they right they're chemicals that are used to make polycarbonate plastic polycarbonate plastic is the hard plastics we have in our world so if you think about all the places where you use plastic and it's hard uh I think of kind of the Nalgene type water bottles epoxies resins things like that that's where you're going to have historically found a lot of BPA of course today this is less the case um but the truth of the matter is they're now replaced by other uh bisphenols so BPS and BPF and the truth of the matter is not clear that we know if those are any better than BPA”
