alt Hacker NewsThat poster seemed to be saying that frying pan PM2.5 was not a health risk:
> Heck, my PM2.5 meter skyrockets whenever I cook anything in a frying pan, because many of the aerosolized oil droplets are PM2.5.
I'm not sure how they determined that PM2.5 is not a neurotoxin, or the full extent of their claims, but frying pans inside are a common cause of minor health problems.

The point was that PM2.5 is a measurement of particle size, and that by itself allows no judgement about its toxicity. The same way you cannot argue that things of 5 centimeter diameter are healthy.
The toxicity judgement comes from the information what substance has the form of PM2.5, and the journo managed to omit that.

They said that the category "small particles" is not equal to the category "neurotoxic".
Much like how "Walks on Two Legs" is not "Men", there may be some overlap in the categories, but the first does not reliably indicate the second. (Or vice-versa.)
