Question

Which one of the following statements is incorrect about DDT?
A. DDT is a pesticide, which is an organochlorine.
B. It is lipophilic and non-Biodegradable.
C. Milk is a good carrier of DDT.
D. DDT does not undergo bioconcentration when it enters the food chain.

Answer 1

Hint: DDT is chemically and is colorless, tasteless, and almost odorless crystal and chemical compound, organochlorine, or dichlorodiphenyltrichloroethane. Initially, it was developed as an insecticide. For its environmental consequences, it became infamous.

Complete answer: Since they are highly soluble in water, DDT and BHC are both regarded as good insecticides and are an effective contact insecticide and are commonly used to destroy mosquitoes and other insects. Owing to the lack of access to other cheaper insecticides, it is also commonly used in developing countries. DDT is banned in different parts of the world due to both environmental damage issues and the potential for harm to human health, there was also evidence linking DDT with the sudden decreases in bald eagle populations due to thinning eggshells.
 -DDT (dichlorodiphenyltrichloroethane) is an organochlorine noted for its insecticidal properties, which is colorless, crystalline, tasteless, and almost odorless.
-It is a non-biodegradable, water-insoluble, chlorinated hydrocarbon that was once used worldwide, especially in agriculture, as a major insecticide. Awareness of its harmful effects on the environment has led to limits on its use in recent years.
-It's lipophilic, but when it joins the food chain, it undergoes bioconcentration, i.e., biomagnification. Milk is a carrier of the cause of DDT, DDT reaches the food chain.
Hence, the correct option is D- DDT does not undergo bioconcentration when it enters the food chain.

Note: Anofex, Cezarex, Dicophane, Dinocide, Zerdane, Chlorophenothane, etc. are some of the generic names for DDT. DDT may be manufactured in different ways, such as xylene or petroleum distillate solutions, aerosols, smoke candles, lotions, powders that are water-wettable. It is an environmental pollutant to which oils and sediments are adsorbed.
