Question

Q. For biomagnification, which of the following should be the characteristics of a pollutant?

Select the correct answer using the code given below:

• A. 1 and 2 only
• B. 3 only
• C. 2 only
• D. 1, 2 and 3

Answer 1

The correct option is A 1 and 2 only

Explanation:

• Pollutants need to satisfy characteristics like long life, biologically active, soluble in fat etc. to make biomagnification possible.
• Biomagnification refers to a process of Biological Magnification, meaning the increase of contaminated substances/toxic chemicals that take place in the food chains. These substances often arise from intoxicated or contaminated environments. They include heavy metals such as mercury, arsenic, pesticides such as DDT, and polychlorinated biphenyls (PCBs) compounds that are then taken up by organisms during food consumption or from the toxic environment. Pollutants need to satisfy characteristics like long life, biologically active, soluble in fat etc. to make biomagnification possible.
