Question

DDT residues are rapidly passed through food chain as DDT is

• A. Water soluble
• B. Moderately toxic
• C. Liposoluble
• D. Nontoxic to aquatic animals

Answer 1

The correct option is C Liposoluble

Dichlorodiphenyltrichloroethane or DDT is a crystalline, colourless and odourless compound which is used as an insecticide. DDT on runoff from the fields reach the water bodies and gets accumulated in the bodies of fishes. When fishes are eaten by birds, it gets accumulated in the body of birds and hence, in this way it gets incorporated in the food chain. It gets deposited in the fatty tissues of animals as it is fat soluble and cause serious health hazards.

Hence, DDT residues are rapidly passed through food chain as DDT is fat soluble i.e. liposoluble.

So, the correct answer is 'Liposoluble'.
