Question

Domestic waste contains:

• A. Non-biodegradable pollutants
• B. Biodegradable pollutants
• C. Hydrocarbons
• D. Both A and B

Answer 1

Answer: (D)

Both A and B

Degradable pollutants degrade after some time, either automatically or through microbial action, e.g., biodegradable sewage, livestock wastes, garbage and domestic wastes. Biodegradable wastes mean wastes which can be cleared by biological agents like microorganisms. Biodegradable pollutants are easily disposed or degraded through natural processes or waste treatment plants. Domestic wastes contain both biodegradable pollutants and non-biodegradable pollutants.

So, the correct option id 'D'.
