Current Question (ID: 17886)

Question:

$\text{Match the pollutant (s) in Column I with effect (s) in Column II.}$ $\text{Column I}$ $\text{A. Oxides of Sulphur}$ $\text{B. Nitrogen dioxide}$ $\text{C. Lead}$ $\text{D. Nitrate in drinking water}$ $\text{Column II}$ $\text{1. Red haze in traffic and congested areas}$ $\text{2. Damage to kidney}$ $\text{3. 'Blue baby' syndrome}$ $\text{4. Respiratory diseases}$

Options:

1. $\text{A. 2, B. 3, C. 4, D. 1}$
2. $\text{A. 1, B. 2, C. 3, D. 4}$
3. $\text{A. 1, B. 4, C. 3, D. 2}$
4. $\text{A. 4, B. 1, C. 2, D. 3}$

Solution:

$\text{HINT: Nitrate in drinking water causes 'Blue baby' syndrome.}$ $\text{Explanation:}$ $\text{A. Low concentration of sulfur dioxide causes respiratory disease e.g., asthma, bronchitis, etc.}$ $\text{B. The irritant red haze in the traffic and congested place is due to oxides of nitrogen.}$ $\text{C. Excess nitrate in drinking water cause methemoglobinemia (blue baby syndrome).}$ $\text{D. Lead can damage the kidney, liver, reproductive system, etc.}$
