DDT is a highly lipophilic colorless solid with a weak, chemical odor that is nearly insoluble in water but has a good solubility in most organic solvents, fat, and oils.
DDT was first banned from use in Norway and Sweden in 1970 (it was not banned in the United Kingdom until 1984).
In particular, DDT has been cited as a major reason for the decline of the bald eagle in the 1950's and 1960's, which was of particularly symbolic interest in that the eagle is the national bird of the United States.
DDT was subsequently banned for agricultural use in many countries in the 1970s; there is still a great controversy regarding the effect of this decision on the use of DDT to fight disease vectors.
DDT was first synthesized in 1874 by Othmar Zeidler, but its insecticidal properties were not discovered until 1939, by the Swiss scientist Paul Hermann Müller, who was awarded the 1948 Nobel Prize in Physiology and Medicine for his efforts [2].
DDT is a persistent organic pollutant with a reported half life of between 2-15 years, and is immobile in most soils.
