A question about nicotine dosage

[Qwerty 42]

I was doing some research into "safe" levels of nicotine, and something I found was an OSHA figure which said that it was safe below 0.5 mg/cu in the workplace. This figure seemed almost impossibly high to me, since most cigarettes contain only about 10 mg of nicotine and the smoker consumes only about 2 mg of it.

Link: http://www.inchem.org/documents/pims/ch ... 0POISONING , ctrl-f for "OSHA" should bring it up.

Does anyone have any input? Is this, in fact, the actual safe threshold?

That's a TWA, which means "Time-Weighted Average for an eight hour shift".

I see. So that works out to about .063 mg/cu/hour, then?
