This is a βparts per ~~million~~ billionβ sort of thing.
Think of it like PFAS or some other harmful chemical (which, you know, it basically is): the layperson would be categorically unable to get a meaningful measurement from a glass of water, but it can still fuck you (and everyone else) up real bad in the long run.
The only particles found were really small: 50 microns
going with that, 350 glasses, 250ml per glass, 1e+12 cubic microns per cm3
So 1 particle in 3502501e+12/50 cubic microns of water
according to my calculator that would be about 5.7Γ10^-10ppm
aka, next to none
yes I did the math using the simple example the doc gave me :0
