Updated On: Sep 13, 2022
- Greenhouse gas
- A fertilizer
- Biodegradable pollutant
- Non-biodegradable pollutant
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The correct option is option D, Non-biodegradable pollutant.
Non-biodegradable pollutants are those unwanted substances that can not be decomposed by bacteria. They are very hazardous to the environment. Examples of non-biodegradable pollutants are synthetic fibres, DDT, insecticides, lead, mercury, arsenic, pesticides, polythene, plastics, silver foils, and so forth. DDT is a non-biodegradable pollutant as till date there is no such enzyme found in any microbes that can degrade DDT.
Therefore, DDT is a non-biodegradable pollutant.
