My wife is an anesthesiologist and I ask her these kinds of questions all the time. It really aggravates her, a little knowledge is really a dangerous thing. If you are really brave try medical web sites. Otherwise, my rule of thumb is that anything less than .5 ATM is too thin, Oygen percentage needs to be .15-.25, adjusted UP if the ATM pressure is lower. Anything higher would be considered a Corrosive atmosphere, and a fire risk as well. Traveller does not concentrate on simply chemical content of the atmosphere, an atmosphere could be toxic or corrosive due to organic compounds, molds, viruses or anything else. The game effect is what is important here.

Thanks, that was what I was looking for. Now, on another subject...

In Traveller there are various different types of atmospheres (toxic,
corrosive, polluted, etc.) at various different pressures (thin, normal,
dense, etc.). The pressures I can deal with as Traveller is very
specific. As to the content, AS has specific chemical contents. Do you
know where I can find a discussion on how the chemical contents effect
humans...What chemicals are toxic? How much O2 is required for an
atmosphere to be breathable? What chemicals are corrosive and how much
can be in the air before it becomes noticeable? Etc.
