- DDT (Dichlorodiphenyltrichloroethane) is a pesticide that is not biodegradable, meaning that bacteria cannot break it down.
- It is a crystalline, colorless, and odorless substance that was widely employed as an insecticide before its negative effects on the environment were discovered.
- Due to the fact that DDT is a fat-soluble substance, it has been found to be extremely persistent in the environment.
- It entered the aquatic food chain and led to biomagnification, according to studies. The destruction of the soil microbial fauna was seen as a result of its easy absorption by soil particles. It evaporates and lingers in the atmosphere as a contaminant.
- It is a non-biodegradable substance as a result.
Hence, option D is the correct answer.
