Question

An organochlorine insecticide is?
A. DDT/aldrin
B. Malathion
C. Tetraethyl pyrophosphate
D. Thiocarbamate

Answer 1

Hint: Organochlorine insecticides are highly toxic, refractory and easily residual characteristics, they were utilized in huge quantities as pesticides in the agricultural production process, resulting in large amounts of soil residues and groundwater permeation from irrigation.

Complete Answer:
Organochlorine (OC) pesticides are synthetic pesticides widely used all over the world. They are related to the compound of chlorinated hydrocarbon by-product that has wide application in agriculture and in the chemical industries. These compounds are recognized for their rich toxicity level, slow degradation and bioaccumulation.

Now, let us find the solution from the option.
- DDT (dichlorodiphenyltrichloroethane) is an organochlorine insecticide, which is a colourless, crystalline solid, tasteless and almost odorless chemical compound.
- Malathion is an insecticide that is mostly utilized in residential areas, agriculture and in human health pest control programs like mosquito eradication.
- Tetraethyl pyrophosphate is an organic phosphate pesticide which serves as a preventer of cholinesterase because it is highly toxic by all routes of exposure.
- Athiocarbamate, is commonly used as a topical antifungal agent against mild to moderate superficial dermatophyte fungal infection in skin.

Thus, the correct option is A .i.e. DDT/aldrin.

Note: Organochlorine pesticides (OCPs) are specifically utilized in agriculture to save cultivated plants. They affect the nervous system, ethane (DDT) is a common pesticide which has been widely utilized to stop the spread of dengue, malaria, leishmaniasis, and Japanese encephalitis via the inhibiting the growth of mosquitoes. Another most usually utilized OCP is lindane.
