How does an animal living hundreds of kilometers from an area sprayed with DDT might get DDT in its body?

Answer 1

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.

Answer 3

An animal that has DDT in its body can move away from the area that has been sprayed by DDT and then an animal eats the other animal with DDT in it, and then the animal living hundreds of kilometres has DDT in its body.

Answer 4

People wanted to get rid of insects so they fed it to them. Birds and other animals eat the insects and get the DDT inside them. DDT doesn't break down inside animals it just stays. The DDT builds up inside animals (bioaccumulation) and causes them to get really weak. It can also pass onto the children of the animal when it is born.

Answer 5

Pesticides like DDT can reach human body through the food chains of the ecosystem. There are two ways:

1) The DDT enters the grass which is eaten by the cows. It can reach the human body through the milk of the cows.

2) The DDT, flows along the rain waters into the water bodies where they accumulate in the bodies of the fish. It can then reach the bodies of the persons eating these fish.
