Seagull is likely to have the highest concentration of the pesticide DDT.
- The amount of DDT is expressed in parts per million. In a food chain, the amount of toxic buildup increases along with the trophic level. In the tissues and fat of an organism, toxins accumulate.
- Aquatic animals are extremely harmful to DDT. DDT has an impact on a number of aquatic animal systems, including the heart and brain. Fish are extremely harmful to DDT.
- DDT is difficult for fish to detect in water. When an animal eats food that contains DDT residue, the DDT builds up in the animal's tissue through a process known as bioaccumulation.
- The biomagnification mechanism causes the concentration of DDT in an animal's body to increase the higher up the food chain the animal is. Here the seagull is the highest in the food chain and thus will be most affected by the DDT concentration.
