Glyphosate is a: ((MCAER 2014))

✅Explanation: Paul Muller, a Swiss chemist, discovered the insecticidal properties of DDT in 1939. His research led to its widespread use during and after World War II to control insect-borne diseases like malaria and typhus.

🔑Key Points:
-DDT was initially used by the military in WW II to control malaria, typhus, body lice, and bubonic plague Cases. Hence a, b are correct.
-DDT is still used today in South America, Africa, and Asia for this purpose.
-Farmers used DDT on a variety of food crops in the United States and worldwide. DDT was also used in buildings for pest control.
-How toxic is DDT?
-Animals
-DDT is slight to moderately acutely toxic to mammals, including people, if eaten. Hence c is correct
-DDT is poorly absorbed through mammalian skin, but it is easily absorbed through an insect’s outer covering known as an exoskeleton. Hence d is correct.
-Is DDT still used?
-DDT was cancelled because it persists in the environment, accumulates in fatty tissues, and can cause adverse health effects on wildlife. In addition, resistance occurs in some insects (like the house fly) who develop the ability to quickly metabolize the DDT.
-DDT (Dichloro Diphenyl Trichloroethane) is used to cure malaria as per the recommendations of WHO.
-Dichlorodiphenyltrichloroethane is commonly known as DDT.
-It was first developed by Othmar Zeidler in 1874.
-The insecticidal action of DDT was discovered by the Swiss chemist Paul Hermann Müller in 1939.
-Paul Hermann Müller was awarded the Nobel Prize in Physiology in 1948 "for his discovery of the high efficiency of DDT as a contact poison against several arthropods".
-The United States banned the use of DDT in 1972, but some countries still use the chemical.
-DDT can be absorbed by eating, breathing, or touching products contaminated with DDT.
