It is a gas.
Your body absorbs some of the oxygen out of air in your lungs
Only a hot mixture of the same gases that are in the air you breathe.
Many people in big cities breathe polluted air. Why? - the pollution is mixed with the air you breathe. =============================== "Can you breathe it?" is not the question you want to ask. You can breathe anything that's in the form of a gas, or particles dispersed in gas ... carbon dioxide, helium, carbon monoxide, steam, nerve gas, tobacco smoke, alpha-particle plasma, etc. For any gas, the question you want to ask is "How long can you survive while you breathe it ?" You cannot survive as long breathing polluted air as you can survive breathing clean air. In other words, polluted air kills people. Not in a minute, not in an hour, and not in a day. But people don't live as long in polluted air, and that's exactly the same as saying that polluted air kills people.
