Criticisms of a DDT "ban" often specifically reference the 1972 United States ban (with the erroneous implication that this constituted a worldwide ban and prohibited use of DDT in vector control). Reference is often made to Silent Spring , even though Carson never pushed for a DDT ban.
Silent Spring is an environmental science book by Rachel Carson. [1] Published on September 27, 1962, the book documented the environmental harm caused by the indiscriminate use of DDT, a pesticide used by soldiers during World War II.
DDT was banned in the United States in 1972. Other factors played a role in the declining populations of bald and golden eagles in the 1950s, 1960s, and 1970s. For instance, one source of golden and bald eagle mortality is the bioaccumulation of toxins in their reproductive system and bloodstream.
The use of DDT in the United States was banned in 1972, except for a limited exemption for public health uses. Public concern about the usage of DDT was largely influenced by the book, Silent Spring, written by Rachel Carson. [9] The ban on DDT is cited by scientists as a major factor in the comeback of the bald eagle in the continental United ...
DDT is an organochlorine insecticide that does not occur naturally. It is a persistent organic pollutant (POP) with a half life of 2–15 years. Concerns were raised about its use in the 1940s but the publication of Rachael Carson's book Silent Spring was the catalyst leading to DDT being banned. DDT was first banned in Hungary in 1968 then in ...
DDT's persistence in the soil for up to 10–15 years after application has resulted in widespread and persistent DDT residues throughout the world including the arctic, even though it has been banned or severely restricted in most of the world.
After the war, DDT became a popular agricultural insecticide. [ citation needed ] DDT's harmful environmental effects largely affected bird populations, as the chemical caused the bird's eggshells to become dangerously brittle and reduced the reproductive abilities of bird populations. [ 21 ]
DDT's hazardous effects on the environment include being linked to the production of fragile eggshells in birds and showed a 90% decline in the birth rates of alligators. [86] Though it is banned in the United States, DDT continues to be used in many parts of the world for agricultural use, insect control, and to fight the spread of malaria.
