it simply happens due to the process named biomagnification
as it enters fishes in lower tropic level then it moves along the food chain but its toxicity increases as it moves above tropic level.
it can effect miggronisms in your brain cause damage to your heart and is found in cigarretes
The use of DDT was banned in the USA in 1973 although it is still in use in some other parts of the world
to allow air to enter into enter their body

DDT is a powerful chemical that can kill living things. When farmers spray DDT on their farms, the rodents and other small mammals in the farms vicinity die. Spotting an easy meal, birds of prey like eagles, vultures etc pick them up. As a result, the chemical enters the birds body causing diseases and even death in most cases. DDT also causes the birds to lay eggs with very thin shells. The thin shelled eggs break easily and the embryo will die.

Human skin is not permeable to water hence water can't enter body through skin .
DDT can be stored in fatty tissues of humans. In women who are pregnant, DDT exposure can occur even in the fetus.
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.
