The DDT is one
of the most famous and disputed insecticide which was discovered in
1939 by Paul Müller. Its was used to solve the malaria and typhus
problem. At the beginning scientist welcomed the new compound and
Paul Müller won the Nobel Prize. However later they realized that it
is much more harmful than helpful.
In Rachel
Carson's book we can read several statements about DDT's harmful
effects. The most unequivocal finding is that, the compound kills
useful insects as well as baleful insects.
The U.S. Environmental Protection
Agency introduced restriction actions, thus the compound was banned
in 1970. In Hungary DDT was banned in 1968 first in the world.
There is no
argument about that the DDT is the most effective insecticide
according to our knowledge. “In terms of efficiently, there is no
other insecticide which could compete with DDT” said Don Roberts,
tropical diseases expert of Uniformed Services University, to
National Geographic.
He also thinks that, in
malaria-stricken areas, basically in the developing world, DDT should
be used once a year.
The Sierra Club environmental
organization has recognized the effectiveness of DDT in the fight
against malaria. “We do not oppose the use of DDT in the developing
world” said Ed Hopkins, head of Sierra Club.
Where the malaria situation is serious
it might be important to consider to use it. But the main problem is
that scientists have no idea how to use it so that the usage does
not effect the environment. In its current form DDT is
life-threatening. Experts recommend that DDT
should not scatter everywhere, but to “dusting” it in little
quantities on the house walls. This method could be less harmful on
the human and natural environment.
