Question

DDT is a
A. Greenhouse gas
B. Degradable pollutant
C. Non-degradable pollutant
D. None of the above

Answer 1

DDT stands for Dichloro-Diphenyl-Trichloroethane. It is an insecticide which is used to kill or to stop the growth of insects.

Complete Answer:
Non biodegradable are those which do not break easily like toxic chemicals, plastics etc. DDT is developed as an insecticide and is used in abundance for its environmental impacts. It is a colorless and odourless crystalline chemical compound.
DDT is a non-biodegradable pollutant widely used as a modern synthetic insecticide. DDT is an insecticide which is a non-biodegradable pollutant. It is used to kill insects as it acts against insect’s eggs and larvae.

The correct option is D, None of the above.

Additional Information: DDT is similar in structure to the insecticide. It is highly hydrophobic and nearly insoluble in water but has good solubility in most organic solvents, fats and oils.
DDT does not occur naturally and is synthesized by consecutive Friedel-crafts reactions. DDT has been marked under trade names including cezarex, Dinocide, Neocid etc. commercial DDT is a mixture of several closely related compounds.
In insects, DDT opens sodium ions channels in neurons, causing them to fire spontaneously, which leads to eventual death. DDT is found to be effective against lice, fleas and mosquitoes (the carriers of typhus, of plague, and of malaria and yellow fever, respectively). It is also effective on other insects that attack valuable crops.

Note: DDT is a persistent organic pollutant that is readily absorbed to soils which can act both as sinks and long term sources of exposure affecting organisms.
DDT is a type of insecticide which kills insects. Insecticides are used in agriculture, medicine, industry and by consumers. Nearly all insecticides have potential to alter eco-systems, many are toxic to humans or animals. Some become concentrated as they spread along the food chain.
