Natural gas is advertised as a toxic hazard -- if a stove is not adjusted properly because carbon monoxide could result. Carbon monoxide is toxic, however, the way it is framed in the media is misleading.
The most toxic exhaust component is not monoxide. It is nitrogen dioxide (NO2), formaldehyde, PAH, etc.
No matter how well adjusted the oxygen/fuel ratio of your stove, these poisons are present -- carbon monoxide or no carbon monoxide.
Unventilated fired devices (stoves, boilers and room heaters) are a great a hazard. Their toxic symptoms are usually misdiagnosed as "colds" and "influenza". Dolan (1985)
Dolan uses carbon monoxide presence as an indicator of exhaust presence in order to reveal such misdiagnoses.
However, a low carbon monoxide reading, is an unreliable, misleading, and deadly indicator of stove safety.
