Question:
Match the following pollutant concentration limits in water with their effects: List-I (Pollutant Concentration Limit in Water) List-II (Effect) Pollutant 1 Effect 1 Pollutant 2 Effect 2 Pollutant 3 Effect 3 Pollutant 4 Effect 4
Match the following pollutant concentration limits in water with their effects:
| List-I (Pollutant Concentration Limit in Water) | List-II (Effect) |
|---|---|
| Pollutant 1 | Effect 1 |
| Pollutant 2 | Effect 2 |
| Pollutant 3 | Effect 3 |
| Pollutant 4 | Effect 4 |
Show Hint
Water pollutants cause specific health effects based on toxicity levels. Excess fluoride leads to dental fluorosis, while nitrate contamination affects oxygen transport in infants.

- Pb \(>50 \) ppb & (IV) Liver damage
- \( SO_4^{2-} \) \(>500 \) ppm & (III) Laxative effect
- \( NO_3^- \) \(>50 \) ppm & (II) 'Blue baby' syndrome
- \( F^- \) \(>2 \) ppm & (I) Brown mottling of teeth \hline \end{tabular} \end{center}
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Effects of Pollutants
- Lead (Pb>50 ppb): Liver damage, as lead toxicity affects major organs.
- Sulfate (\( SO_4^{2-}>500 \) ppm): Laxative effect, leading to digestive disturbances.
- Nitrate (\( NO_3^->50 \) ppm): Causes 'Blue baby' syndrome, where oxygen transport in infants is impaired.
- Fluoride (\( F^->2 \) ppm): Leads to brown mottling of teeth (dental fluorosis).
Conclusion
Thus, the correct answer is:
\[
A-IV, B-III, C-II, D-I
\]
