What is biomagnification?

-
Biomagnification is the process in which toxins are concentrated in an organism as larger animals continue to eat the smaller animals. this process moves toxins up the food chain to larger organisms and is of particular concern with regard to concentrating dangerous toxins in large species.


in general, the use of biomagnification is associated with dangerous toxins and chemicals that are released because of human action. Biomagnification can be broken into two categories: persistent organic pollutants and metal. Both of these groups are not easily degraded by organisms.persistant organic pollutants are novel organic substances made by humans.
 Metals can not be degraded because they are an element.
the example of biomagnification is the accumulation of insecticide DDT or any other PAHs and metal in zooplanktons that zooplanktons consumed by small fishes then DDT concentration moves to high in small fishes than zooplankton

Tiwari Committee 1980

-
                             Tiwari committee (1980) The Tiwari committee was set up in February 1980 to suggest administrative and legislative measures that out to be taken for the protection of the environment. This committee submitted its report in September 1980and made for reaching recommendations. According to this for the protection of the environment. 1.        Land and water management. 2.        Natural living resources. 3.        Environmental pollution and environmental impact assessment. 4.        Human settlement. 5.        Environmental education and awareness.     The committee reviewed the exciting laws related to the environment and pointed out the following shortcoming: 1.        Many laws ...

These are known as relatively rapid movements. the material involved the relatively dry.the size and shape of the detached mass depend on the nature of the discontinuities in the rock. the degree of weathering and the steepness of the slope. depending upon the type of movement of material several types are identified in this category. slump is slipping of one or several units of rock                                           Fig : Slumping of debris with backward rotation. debris with a backward rotation with respect to the slope over which the movement takes place Rapid rolling and sliding of earth debris without backward rotation of mass is known as debris slide . debris fall is nearly a free fall of earth debris from a vertical and overhanging face. sliding of individual rock masses down bedding joint or fault surfaces is rockslide .

Effects of Biomagnification?

As the substance biomagnification leech into the environment and absorbed, we seeing their effects. Generally, the organisms at the bottom of the food chain are not entirely affected by biomagnification because the concentration of the substance is very low. As it increases the higher level we being to see the problem. One of the most infamous persistent organic pollutants is DDT, an organic compound use as an insecticide.DDT is slowly accumulated in plankton, which was eaten by fish. these fish, which now accumulated more DDT, were then eaten by bigger fish until they were eventually eaten by birds. the birds had eventually large amount of DDT in their system. Fig: DDT Biomagnification another part cyanide fishing is widely used in southeast Asia by fishers because it is effective way of catching fish. the cyanide is introduced as a crushed tablet placed in squirt bottles. these are then sprayed across the water and reef fishes are stunned by the cyanide. As the coral reef dies, the o...
