Question

Which of the following gas(es) is/are atmospheric pollutants?

• A. $CO$
• B. $N{O}_2$
• C. $S{O}_2$
• D. None of the above.

Answer 1

Answer: (A), (B), (C)

$S{O}_2$

These gases are atmospheric pollutants as all lead to air pollution because nitrogen dioxide $\left(N{O}_2\right)$, sulfur dioxide $\left(S{O}_2\right)$, and carbon monoxide $\left(CO\right)$ are important ambient air pollutants. High-intensity, confined space exposure to $N{O}_2$ has caused catastrophic injury to humans, including death. Ambient $N{O}_2$ exposure may increase the risk of respiratory tract infections through the pollutants interaction with the immune system. Sulfur dioxide $\left(S{O}_2\right)$ contributes to respiratory symptoms in both healthy patients and those with underlying pulmonary disease. . Carbon monoxide $\left(CO\right)$ is produced by incomplete combustion of carbon. Mainly released by automobile exhausts, incomplete combustion of coal, firewood, petrol, etc. It is highly poisonous to living beings because of its ability to block the delivery of oxygen to the organs and tissues.
