The correct Answer is:
To solve the matching question regarding pollutant types and their examples, we will analyze each type of pollutant and find the correct example from the given options. ### Step-by-Step Solution: 1. **Identify Biodegradable Pollutants**: - Biodegradable pollutants are substances that can be broken down by microorganisms. - **Example**: Domestic sewage is a classic example of a biodegradable pollutant as it can be decomposed by bacteria. - **Match**: A) Biodegradable → iv. Domestic sewage 2. **Identify Non-degradable Pollutants**: - Non-degradable pollutants are substances that cannot be broken down by natural processes. - **Example**: DDT (Dichloro-Diphenyl-Trichloroethane) is a well-known pesticide that is non-biodegradable and accumulates in the environment. - **Match**: B) Nondegradable → iii. DDT 3. **Identify Qualitative Pollutants**: - Qualitative pollutants are those that affect the quality of the environment, often including chemicals used in agriculture. - **Example**: Herbicides are chemicals used to kill unwanted plants and can affect the quality of soil and water. - **Match**: C) Qualitative → ii. Herbicides 4. **Identify Secondary Pollutants**: - Secondary pollutants are not emitted directly but form in the atmosphere through chemical reactions. - **Example**: PaN (Peroxyacetyl Nitrate) is a secondary pollutant formed from the reaction of volatile organic compounds (VOCs) and nitrogen oxides in the presence of sunlight. - **Match**: D) Secondary pollutant → i. PaN ### Final Matches: - A) Biodegradable → iv. Domestic sewage - B) Nondegradable → iii. DDT - C) Qualitative → ii. Herbicides - D) Secondary pollutant → i. PaN ### Summary of Matches: - A - iv - B - iii - C - ii - D - i
