Question

Which of the following is mostly a degradable pollutant?

• A. DDT
• B. Aluminium foil
• C. Domestic wastes
• D. Mercury salts

Answer 1

The correct option is C Domestic wastes

Pollutants can be classified as degradable or non-degradable, based on their ability to be degraded upon disposed of. A degradable pollutant degrades after some time, either automatically (e.g., heat) or through the agency of microorganisms (e.g., domestic sewage, livestock wastes, market garbage). Among the following, domestic wastes are mostly degradable while others are not.

So, the correct answer is option C.
