CO2 kills humans.

Does it also kill organisms? Does it also kill viruses?

• I'm inhaling it right now and am still alive. The dose makes the poison. – Todd Minehardt Mar 11 at 2:26
• Does an extreme does of CO2 kill viruses? – Andy Mar 11 at 2:28
• At what temperature and pressure? – DrMoishe Pippik Mar 11 at 2:34
• temp: 98.6 --- pressure: 14.696 psi – Andy Mar 11 at 2:40
• Viruses are not quite alive in the first place. – Ivan Neretin Mar 11 at 4:34

Larger concentration of $$\ce{CO2}$$ directly affects only organisms with metabolism involving $$\ce{CO2}$$.
$$\ce{CO2}$$ is used, in mixture with $$\ce{N2}$$, as protective gas for packed food. It may not necessary kill bacteria, rather stops their growth.
It may be affected indirectly as $$\ce{CO2}$$ dissolved in water causes mildly acidic environment.
In summary, $$\ce{CO2}$$ cannot be considered as desinfectant.
