9.Which of the following air pollution gets dissolve in haemoglobin of the
blood more rapidly than oxygen?
A. PAN
B. Carbon dioxide
C. Carbon monoxide
D. Ozone
Answer ||| C
Solution ||| Carbon monoxide dissolves in the hemoglobin of blood more
quickly than oxygen, causing the hemoglobin's oxygen carrying capacity
significantly decreases. As a result, this can become a cause of
exhaustion, unconsciousness and even death.
