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?
