Download file to see previous pages The utilization of this substance as the insecticide started in the 1940th. For the next 30 years, DDT helped to fight malaria and typhus, as well as was used in agriculture against pests. However, the growing concerns about the environmental impact of DDT led to its banning in many countries. The other reason to put it into the blacklist of forbidden substances was the fact that insects became resistant to DDT. The DDT issue became controversial.

Experts divided into two groups. The advocates of DDT claim that there is no need to ban this substance because it is still effective against vectors of malaria. The opponents suppose that insecticides less harmful to the environment should be used to fight malaria. The complex of economic, planning, medical measures will be the most effective tool against this disease. Each part has its own arguments.

I am going to examine the opinion of both sides presented in the popular sources and in the scientific literature. I chose five articles on the websites and at the online version of the Scientific American. I also analyzed information presented in the university press books and the official reports about DDT. Both types of sources present the opinion of the defenders of DDT and their opponents.

It is a colorless, odorless and tasteless substance. DDT is insoluble in water, but fats, oils, and organic solvents can dissolve it. The insecticidal action of DDT was discovered by Paul Hermann Muller in 1939 (ScienceHeroes.com 1, 2009). Since that time DDT became widely used in Europe, Asia, and America.
DDT opens sodium ions channels in neurons of insects. It leads to spasms and death of insects like mosquitos and bugs. DDT can be used for a variety of species. It fights both pests and vectors of diseases. ...Download file to see next pagesRead More

Of course this action in and of itself opens Pandora’s box due to the fact that the first question that one must ask when posited such a statement is on whose interpretation of morality is “morally devious” based. Finally, it should be noted that although censorship can be implemented successfully for a period of time, as indicated by the reference to the Soviet Union, it inherently fails...

...DDT (dichlorodiphenyltrichloroethane Current Perspectives On A Global Ban Dichlorodiphenltrichloroethane, better known as DDT, was the first pesticide to be applied to the systematic environmental control of insects (Barnhoorn et al. 22). The Swiss scientist Paul Muller was the discoverer of the insecticidal properties of this organochlorine chemical in 1942 and was awarded the Nobel Prize for his efforts. DDT is actually a mixture of isomeric forms of organochlorine. It acts as a nerve poison that paralyzes and kills insects; unfortunately, its neurotoxic effects are experienced by many other forms of life if exposed to this pesticide in the context of its environmental application (Prüss-Ustün,  Bonjour, and Corvalán 47).
