Carbon monoxide, which is a tasteless, colorless and odorless gas, is one of the gases that cause the greenhouse effect and intensify global warming.

Remaining in the air for more than 60 days, carbon monoxide causes very serious damage to the atmosphere with its annual emission of 232 million tons.

The transportation sector contributes the most to the annual emissions of this gas, accounting for 70 percent. The most significant sources of carbon monoxide in enclosed spaces are cigarettes, stoves, and heaters.

Carbon monoxide is also very dangerous for health, it binds to hemoglobin in the blood and prevents the transportation of oxygen, causing the oxygen level in tissues to decrease.

Carbon monoxide is considered one of the most important air pollutants that causes cardiovascular diseases.

Carbon monoxide poisoning can cause headaches, shortness of breath and nausea. Exposure to high doses of this gas can lead to coma and ultimately death.
