Doesn't need to have the same boiling point, just needs to have some partial vapor pressure at 1 atm and be miscible with water.

One big mechanism for dispersal is sea spray aerosols, probs because pfas chemicals have fun surface chemistries. Concentration of pfas in sea sprays can be 10,000x concentration in bulk seawater

PFAS has a boiling point of 189C. I don’t think many things naturally get this hot so it seems unlikely.

So that nice smell of ocean air is actually poisonous?

It could also stick to dust particles that happen to float around. Especially in cities, I usually try to avoid exposure to rainwater for the first few hours of rain, because it clears the air of a lot of gunk (heavy metals, exhaust gases, pollen, spores, forever chemicals, ...) that I don't exactly want to have near my body.

If this is true then we’re just breathing it in all the time because it’s in the air. Sounds like that should be a bigger headline.

Yes, that's a f*king big problem as well, similar to how it was with leaded gasoline! Microplastice are floating around as well, btw.

Agree. Was hoping to see the mechanism of how it got in the rainwater. Fluff article.
