DDT is toxic to a wide range of living organisms, including marine animals such as crayfish, daphnids, sea shrimp and many species of fish. DDT, DDE and DDD magnify through the food chain, with apex predators such as raptor birds concentrating more …

2025年3月17日 · DDT, a synthetic insecticide that belongs to the family of organic halogen compounds and is highly toxic toward a variety of insects as a contact poison that apparently exerts its effects by disorganizing the nervous system.

2021年7月1日 · Americans sprayed more than 1.35 billion tons of the insecticide—nearly 7.5 pounds per person—on crops, lawns and pets and in their homes before biologist Rachel Carson and others sounded the alarm...

Most laboratory animal toxicity studies of DDT, DDE, or DDD have involved oral exposure; there are only a small number of available inhalation or dermal contact studies (see Figure 2-1). The most widely studied health effects examined in human and animal studies were reproductive, neurological, and developmental effects, and cancer (Figure 2-1).

DDT has been suggested to be toxic to a range of wildlife including birds and marine animals, and its metabolite DDE (dichlorodiphenyldichloroethylene) causes eggshell thinning of certain bird species such as bald eagle and brown pelican, leading to declines of their populations (1,2).

2025年3月6日 · DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations.

Information on the toxicity of DDT, DDE, DDD, and their isomers comes from numerous epidemiology studies examining possible associations between levels of DDT, DDE, or DDD in human tissues or fluids and occurrence of various noncancer and cancer health outcomes, as well as from over 150 oral toxicity studies in laboratory animals.

2016年2月11日 · Perhaps no chemical evokes a stronger visceral response in Americans than DDT. Much of the public would consider it to be extremely poisonous. Some contend it is harmless. The toxicology is more nuanced, which is why it's rarely discussed.

2019年2月15日 · DDT, also known as dichloro-diphenyl-trichloroethane, belongs to a class of pesticides called organochlorides. DDT can cause liver damage including liver cancer, nervous system damage, birth defects, and other reproductive harm.

Since DDT was banned in 1972, exposure to DDT, DDE, and DDD has decreased dramatically. Small amounts may still be found in some food. Most people are not likely to be exposed to DDT, DDE, or DDD. The most common way to be exposed to small amounts of these chemicals is from eating contaminated food such as meat, fish, poultry, and dairy products.
