Biomagnification Case Study
Biomagnification is the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed. Also known as bioamplification or biological magnification, occurs when the concentration of a substance, such as DDT or mercury, in an organism exceeds the background concentration of the substance in its diet.
DDT is synthetic organic compound used as an insecticide. Like other chlorinated aromatic hydrocarbons, also persist in the environment and become concentrated in animals at the head of the food chain. Its use is now banned in many countries. DDT is a colorless, crystalline, tasteless and almost odorless organochloride known for its insecticidal properties. DDT was used to kill insects. To help maintain a population. But as they died depending on the bug or insect different animals ate them, and accumulated the toxin in their body also. After a while the toxin would build u and move onto the next animal that ate the second consumer from those that started this. ( for example cricket>frog>snake>owl or hawk>fox or bear) So it started with the contact with the cricket touching the source of it which got eaten by the frog then next the snake so on and so forth. its travels by eating those already infected with it. it can kill just about all animals if they have enough in their system. DDT isn't one of those pesticides that breaks down on its own or at all. But is being band. It has recently been said to cause cancer.
