Carbon what?

Carbon monoxide (CO) and carbon dioxide (CO2) are often confused because of their similar names and chemical symbols. They are both compounds of carbon and oxygen, but differ significantly in terms of their chemical properties, sources, effects on human health, and environmental impacts.

Carbon monoxide is a colorless, odorless, and tasteless gas that forms when carbon-containing fuels (such as gasoline, natural gas, and wood) are burned incompletely due to a lack of oxygen. It binds strongly to hemoglobin in red blood cells, preventing oxygen from being transported effectively through the bloodstream. This can lead to symptoms like headaches, dizziness, confusion, and, in severe cases, unconsciousness or death. Common sources of carbon monoxide include vehicle exhaust, faulty furnaces, and indoor heating equipment.

Carbon dioxide, on the other hand, is a colorless gas that is naturally present in the Earth's atmosphere and is produced during various natural processes, including respiration (breathing), volcanic activity, and decomposition. While typically not as toxic as carbon monoxide, excessive CO2 concentrations can have profound effects on indoor air quality and human health.

Increased carbon dioxide levels within a room can indicate higher levels of “rebreathed” air, and therefore poor ventilation, allowing you to take action.
