Question

What is bio magnification? Name two heavy metals which, when magnified resulted in diseases in humans.

Answer 1

Bio magnification is a process in which the concentration of a non-biodegredable substance such as insecticide progressively increases from one trophic level to another.

Typical example of bio magnification includes bio magnification of element mercury (Hg), which can lead to minamata disease in the human population. Moreover, the progressive bio accumulation of element cadmium (Cd) has resulted in itai itai disease in Japanese population.
