Biomagnification

Pollutants enter the environment through food chains and food webs. Toxic materials are discharged into the waters to seep into the body of algae. Furthermore, algae are eaten by small shrimp. Small shrimp eaten by large fish. And if the fish is caught and then eaten by humans, then the contaminants will get into the human body.
Typically, pollutants that enter the waters have a small degree. This is because the contaminants it has suffered dilution. If the pollutant is absorbed by the body of the algae, then the levels have risen hundreds and even thousands of times. Even contaminants in the water that only 0.00007 ppm, in the body of algae dept be 0.007 ppm. Because of the small shrimp-consuming not just one but many algal cell algae cells, the small shrimp in the body levels of pollutants may be 0.7 ppm. In the body of fish, pollutant levels were increased to 25 ppm. In the body of people who often eat fish, levels of pollutants will increase to 75 ppm. The process of elevated levels of contaminants through the living body is known as biological concentration.
