Drawback of DDT as pesticide is

• A. It becomes ineffective after some time
• B. It is less effective than others
• C. It is not easily/ rapidly degraded in nature
• D. Its high cost

Answer 1

The correct option is C It is not easily/ rapidly degraded in nature

Dichlorodiphenyltrichloroethane (DDT) is an organochlorine compound used as an insecticide in agricultural fields. The major disadvantage of DDT is bioaccumulation or not easily degrading nature, due to fat solubility it is accumulated in living tissues. The human body is not able to break it which cause its build up in the food chain and causing poisoning in the animals. Its effects can be seen in birds as the production of thin eggshells vulnerable to damage.

Hence, the correct answer is 'It is not easily/rapidly degraded in nature'.
