Carbon monoxide is a pollutant because it:
Correct answer: A. Reacts with haemoglobin
- A. Reacts with haemoglobin
- B. Makes the nervous system inactive
- C. Reacts with O2
- D. Inhibits glycolysis
Explanation
Carbon monoxide is produced due to incomplete combustion, metallurgical operations and naturally by plants as well as animals. Carbon monoxide has 200 times more affinity to haemoglobin as compared to oxygen. Carbon monoxide combines with haemoglobin and forms a stable compound called carboxyhaemoglobin. At 50 ppm, CO converts 7.5% of haemoglobin into carboxyhaemoglobin within 8 hours. It impairs oxygen transport resulting in headaches, decreased vision, cardiovascular malfunction and asphyxial.
