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.

Why is ddt in cigarettes?

DDT, or dichlorodiphenyltrichloroethane, is not intentionally added to cigarettes. However, trace amounts of DDT and other pesticides can be found in tobacco due to agricultural practices where these chemicals were historically used to control pests. The presence of DDT in tobacco is a result of environmental contamination rather than a deliberate inclusion in cigarette production. Regulatory measures have since limited the use of DDT, but residues can persist in the environment.
