Apart from these substances, natural air can contain further components such as water vapor and traces of other gases, e.g., methane CH., ammonia NH., carbon monoxide CO and dinitric oxide N.O as a result of decomposition processes, as well as low concentrations of ozone, possibly as a result of stratospheric penetration.
