Eagle populations recovered after the ban on DDT.
The concentration of DDT in the fish is 430,000 times greater than the concentration of DDT in the water.
DDT or dichlorodiphenyltrichloroethane is a colorless crystalline substance that is used as an insecticide. DDT and some related compounds are primarily stored in fats and other organic solvents.
DDT is used as an insecticide which kills on contact. It is extremely harmful and was banned in United States since 1972. Before it was banned, it was used to protect crops from insect damage, but it killed too many animals and plants, while insect populations grew more and more resistant to DDT. This led to ban in DDT in many countries.
DDT is a pesticide that was used to kill bugs. It's bad for the environment because it was killing the animals that would eat those bugs once they were dead, and the population of those animals was decreasing fast. It was banned once scientists realized what it was doing to the animals.
He sprays DDT.
There are inumerable examples. The time dilation effect of relativity had essentially nothing to do with the reasons for the ban on DDT. Yes, that was an important one, but it was less unassociated with DDT than the link between vitamin deficiency and scurvy, and the isotropic expansion of the universe were.
Sicknesses from DDT are an area of contention between the "No problem!" side and the "Doom!" side. Studies have yielded conflicting results which cannot be resolved at this level of involvement.There is always some discussion on the balance of impacts. The incidence of malaria prevented by DDT may be sufficiently "good" to out weigh the problems. Luckily this question does not request any discussion of the ethics of DDT use.Direct Toxic Effects* The US National Toxicological Program rates DDT as"moderately toxic"* WHO rates it as "moderately hazardous"* It is not considered to be acutely toxic by any agency. == * Occupational exposure to DDT has been tied to some nerve and brain problems in retired DDT production workers * Farmers exposed to DDT (long term) develop an increased rate of non-allergic asthma * Some studies indicate a link to diabetes Cancer * The United States National Toxicology program and the International Agency for Research on Cancer feel DDT and related chemicals may be a carcinogen due to the configuration of the molecules. The potential cancers include pancreatic cancer and liver cancer. Other studies are looking at testicular cancer and non-Hodgkin Lymphoma. * The whole question of the impact of DDT on breast cancer is under study. It may be very dependent on the age at which exposure occurs or tied to specific DDT isomers. Other Medical Problems Some DDT isomers and its metabolites are similar to estrogen and can cause problems. These types of compounds may affect reproductive success, fetal health and sexual health.
