Why is carbon monoxide considered the most dangerous air pollutant?
Most dangerous pollutant:
Carbon monoxide is considered the most dangerous air pollutant because the complex produced by CO and hemoglobin is more stable than the complex formed by oxygen and hemoglobin, carbon monoxide (CO) is considered the most harmful air contaminant. At CO concentrations of 3-4 percent, the blood's oxygen-carrying capacity is diminished. Symptoms include headaches, impaired vision, anxiety, and cardiovascular issues. It's possible that a larger concentration would kill you.
