Which of the following pollutants of airould affect the capacity of blood inan bodies to absorb 02 from lungs?wouNO2.SO4.CO and Co,

Answer»

Nitrogen dioxide (NO2)and carbon monoxide are important ambient air pollutants.

High-intensity, confined space exposure to NO2 has caused catastrophic injury to humans, including death.

Increased levels of carbon monoxide reduce the amount of oxygen carried by haemoglobin around the body in red blood cells. The result is that vital organs, such as the brain, nervous tissues and the heart, do not receive enough oxygen to work properly.
