Solution
DDT
Explanation:
Non-biodegradable pollutants are substances that cannot be broken down or decomposed by natural agents like bacteria and fungi. DDT (Dichlorodiphenyltrichloroethane) is a synthetic pesticide that is highly persistent and toxic. Microorganisms do not have the enzymes necessary to break their chemical structure, making them a major non-biodegradable pollutant.
