A perfect example of the dangers brought by mindless use of pesticides is the US Forest Service’s mass-use of DDT for combating the spruce budworm in Spraying the pesticide over , acres of woodland, they ended up exterminating not just the spruce budworm – but also natural predators of the spider mite.

If there is a single pesticide almost everyone can name, it's DDT. DDT was one of the first chemicals in widespread use as a pesticide. Following World War II, it was promoted as a wonder-chemical, the simple solution to pest problems large and small.
Today, nearly 40 years after DDT was banned in the U.S., we continue to live with its long-lasting effects. As the use of DDT spread, a handful of scientists noticed that its reckless use was causing considerable harm to wildlife populations.
These scattered reports culminated in the now-famous book Silent Spring by scientist and author Rachel Carson, which describes the dangers of widespread pesticide book's title comes from the effect DDT and other chemicals were having on songbirds, which Author: Marc Lallanilla.

Spraying programs (especially using DDT) were curtailed due to concerns over safety and environmental effects, as well as problems in administrative, managerial and financial implementation.
Efforts shifted from spraying to the use of bednets impregnated with insecticides and other al formula: C₁₄H₉Cl₅. The pesticide threat to fishes may be divided into three parts.
One, as we have seen, relates to the fishes of running streams in northern forests and to the single problem of forest spraying. It is confined almost entirely to the effects of DDT.4/5(32).
Spraying DDT on livestock and crops led to them almost doubling their yields. DDT after being sprayed on crops and livestock are eventually concentrated to a greater extent as one moves up the food chain, with humans being at the top.
The greater concentration of DDT has been linked to cancer in humans. DDT or 2,2-bis(p-chlorophenyl)-1,1,1,-trichloroethane, chlorinated hydrocarbon compound used as an introduced during the s, it killed insects that spread disease and fed on crops, and Swiss scientist Paul Müller was awarded the Nobel Prize in Physiology or Medicine for discovering () DDT's insecticidal properties.
DDT, however, is toxic to many animals. alfalfa is sprayed with DDT and then ground into meal which is fed to chickens who lay eggs and then people eat the eggs that contain concentrated amounts of DDT. Hay is sprayed with DDT, cows eat it, and then milk has concentrated amounts of DDT.
Butter may have an even higher concentration. Nor was this the limit of DDT’s mischief. Annihilation of ladybug beetles by the spraying resulted in a tremendous multiplication of aphids, which are not affected by DDT but are naturally controlled by ladybugs. The forest was on the way to being completely defoliated when rains halted the outbreak; aphids are shortlived in wet weather.
Silent Spring Book Cover of Silent Spring by Rachel Carson. Source. Considered one of Carson’s most exceptional and groundbreaking books that marked a new public awareness about the use of chemical pesticides, especially DDT, Silent Spring was published on Septem The discovery of DDT before the World War, won Swiss chemist, Paul Müller, a Nobel Prize.
How DDT Affects People’s Health. Human health effects from DDT at low environmental doses are unknown. Following exposure to high doses, human symptoms can include vomiting, tremors or shakiness, and seizures.
Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen. Levels of DDT.
In some parts of the world disease can be linked with spraying in quite a different way. For some reason, snail-like mollusks seem to be almost immune to the effects of insecticides. This has been observed many times. In the general holocaust that followed the spraying of salt marshes in eastern Florida (pages –47), aquatic snails alone.

Silent Spring is an environmental science book by Rachel Carson. The book was published on Septemdocumenting the adverse environmental effects caused by the indiscriminate use of accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.
Author: Rachel Carson. States banned the use of DDT inbut some countries still use the chemical. DDT has also been used in the past for the treatment of lice. It is still in use outside the United States for the control of mosquitoes that spread malaria.

The federal case took a major turn inwhen the newborn Environmental Protection Agency took over the beleaguered battle on banning DDT. By now the case had gone up to the D.C. Court of Appeals, and EDF had opened an office in Washington D.C.
In the book, Wurster’s frustration over the EPA’s reticence to prohibit DDT is palpable. These studies suggest that DDT, and less so DDE, may be associated with neurodevelopmental deficits. In addition, breast-feeding may modulate some of the negative effects of DDT, but this needs to be examined when exposure is high such as in communities where indoor residual spraying is occurring.control, and DDT house spraying has its limitations.
However, DDT remains a remarkably effective tool that should still be used. There is a continuing need for operational research to improve the cost-effectiveness of this approach. It is an astonishing fact that WHO guidance for spraying houses is the same today as it was in the.
