The Full form of DDT is Dichloro Diphenyl Trichloroethane. DDT is a tasteless, colorless, crystalline and almost odorless organochloride substance which is famous for its insecticidal properties. It is poisonous for both humans and animals. It is accumulated in tissues and remains active for many years. Generally, it is used in agriculture and farming to kill the insects and protect the crops. The molecular formula of DDT is C14H9Cl. It is highly hydrophobic and not soluble in water but it is soluble in most of the organic solvents, oils and fats. It is produced artificially by the reaction of chloral (CCl3CHO) with chlorobenzene (C6H5Cl) in the presence of the catalyst sulphuric acid (H2SO4). When it is sprayed on the plants, the insects residing on the plants are exposed with it. It affects the insect’s neurons which lead to eventual death. It also puts a very adverse effect on the human life cycle through edible plants. If we talk about its adverse effect on humans, it would be a very harmful substance for them. It leads to a lot of diseases like diabetes, liver cancer, breast cancer and uncontrolled cell mutation which later leads to tumor and cancer in humans.
