Question

The pesticide used as a preventive measure in buildings is
A. Aldrin
B. Dieldrin
C. Endrin
D. DDT

Answer 1

Hint: In order to combat different predators and disease vectors, such as mosquitoes, ticks, rats and mice, pesticides are used. For the prevention of weeds, insect infestation and diseases, and are also used in agriculture. Chlorinated cyclodienes are used in buildings.

Complete answer: Pesticides are soil contaminants that are significant. Insecticides, fungicides, algicides, rodenticides, and weedicides are used. In general, pesticides have a wide range and act as biocides. The essential class of pesticides are organochlorines and chlorinated hydrocarbons. Dichloro diphenyl trichloroethane (DDT), Benzene hexachloride (BHC), aldrin, dieldrin and endrin are the essential ones. They are permanent, fat-soluble and exhibit biomagnification and are also toxic to higher species at the trophic stage. Aldrin has been used to guard against insects, such as termites, in homes. Short-term adverse health effects, or acute effects, may be caused by pesticides, as well as permanent adverse effects which can occur months or years after exposure. Stinging skin rashes, blisters, blindness, fatigue, dizziness, diarrhoea and mortality are also forms of acute health effects. Pesticides are unbelievably detrimental to human health. It has been proven that pesticides cause reproductive and developmental effects, tumours, damage to the kidneys and liver, endocrine destruction, etc. Data reveals that kids in utero are also exposed to pesticides.
Hence, the correct answer is option A.

Note: In most conditions, a pesticide half-life can range from a few hours to 4-5 years in an agricultural environment. Most pesticides in the soil are broken down by microbes, so environmental factors that decrease microbial activity (cold dry conditions) can prolong the residual pesticide in the soil.
