UGC NET Environmental Science Mock - 2 - Question 4

Consider the following about Biomagnification:

1). It refers to the tendency of pollutants to concentrate as they move from one trophic level to another.

2). In order for Biomagnification to occur, the pollutants must be short-lived, mobile, soluble in water only and biologically active.

Select the correct code:

Detailed Solution for UGC NET Environmental Science Mock - 2 - Question 4

Statement 1 is correct.

Statement 2 is incorrect as for Biomagnification to occur, pollutant has to be Long lived, Mobile, Soluble in Fat and biologically active.

If it is short-lived, it will be broken down before it can become dangerous. If it is not mobile, it will get stick to one place only. If it is soluble in water, it will be washed away in excretion.

So in order to retain it must be fat soluble
