∙ 13y agoDDT was first produced in 1874 and its effectiveness as a pesticide was not discovered until 1933. It was banned in the USA in 1972, and the use was banned worldwide by the Stockholm Convention in 2001.
Of course, not everybody signed the Stockholm convention. China and North Korea and India still produce and use DDT.
Illegal use is common wherever you find bed bug infestations, stagnant water and malarial mosquitoes. I can't find any citations, but I can tell you that throughout Africa and Southeast Asia I have seen quite a few towns with surreptitious chemistry labs that are producing DDT by the gallon.
DDT is also found in many existing products, like tobacco. It is not used directly to grow or treat these products, it is simply absorbed from the soil.

What physical property od DDT contributes to its bioaccumulation in animals?
The physical property of DDT that contributes to its bioaccumulation in animals is its inability to break down easily. This results in it being stored in the fatty issues of animals.
Is DDT illegal?
The use of DDT was banned in the USA in 1973 although it is still in use in some other parts of the world
Speculate about why the levels of DDT fall more slowly in porpoises than in other animals in the ecosystem?
DDT may stay in the system of porpoises longer than with other animals because porpoises lact the necessary enzymes to break down this type of poison. The use of DDT as a pesticide has endangered many animals in the past, and is not longer being used in the United States.
How does the DDT get from the mother to the pup after the pup is born?
DDT gets into animal tissue and remains there, building up over time. It typically gets into the animal from the things that the animal eats. With very young animals, the DDT get from the mother to the pup after the pup is born by passing through the mother's milk and into the pup.
How has DDT affected raptor populations?
Osprey were most susceptible because they were higher up the food chain. *DDT runoff into streams *Minnows, crayfish, insects consumed some *Small fish ate those creatures, and so got an additive dose of all the DDT they were carrying *Larger fish ate the smaller ones and, again, the DDT load of each smaller fish added to that *Osprey consume large fish. THUS the osprey, as an end predator consumed the most DDT. Factor in that, the higher up the food chain you go, the fewer individuals there are. The DDT made the eggshells fragile, so fewer osprey were hatched. So their numbers were reduced even more in comparison to those organisms that were more abundant to begin with.
Is DDT biodegradable?
No. It is still found, even in pristine environments, decades after its use was banned.
It is right for us to use pesticides such as ddt at all and why?
DDT is toxic for humans and animals.
Why was there concern about the use of ddt?
DDT is toxic for many animals and is very slowly degraded in the nature.
What was three ways DDT was beneficial to farming?
DDT destroy insects but is toxic for humans and animals.
Why did the US to stop using DDT?
DDT is toxic for humans and animals and also is persistent in the environment.
How could an animal living hundreds of kilometers away for an area sprayed with DDT still be at risk from DDT poisoning?
Many animals migrate at specific times of the year. An organism with DDT in its tissues may migrate a distance from the area it was sprayed; it may be consumed by a carnivore that would store a higher concentration of DDT in its body tissue. Migrating birds can carry DDT in their bodies even though they inhabit and can be consumed in an ecosystem that is distant from the one that is sprayed. The peregrine falcon is a species of bird found to have high concentrations of DDT in its body. The habitat of the falcon is quite broad, ranging from the North American boreal forest to areas of the southern United States. Falcon prey on organisms in areas where use of DDT is still prevalent, then migrate to areas where the use of DDT has been banned.
What does DDT stand for?
On 1972 DDT stands for Dichloro-Diphenyl-Trichloroethanedichlorodiphenyltrichloroethane, it is an insecticide that is toxic to people and animals.
What are the pros and cons of DDT?

Who might disagree with the use of ddt in africa?
people that understand that DDT is a problem to the environment, humans and animals
How does DDT pesticide harm animals respiration?
here are the reaons1.DDT is for killing bugs wich farmers use. If a insect dies a bird could eat it. But the spray on the bug is still there It spreads into the bird and the bird dies. Than othetre animals will eat and the food chain goes and each dies in seconds.2.DDT could even spread in water. If if DDT goes on a bush I t might drip to the ocean and it is pollution
What is the major reason spraying with DDT and for banning it?
DDT is a very useful insecticide but also is dangerous for humans and animals.
