Question

Assertion(A): The medium which is affected by the pollutants is receptor.
Reason(R): The medium which reacts with pollutants is sink.

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true but R is not correct explanation of A.
• C. A is true and R is false
• D. A is false and R is true

Answer 1

Answer: (B)

Both A and R are true but R is not correct explanation of A.

The "medium" (e.g. soil) or organism (e.g. fish) affected by the pollutant or contaminant is called a receptor, whilst a sink is a chemical medium or species that retains and interacts with the pollutant. Neither of them are explanations for each other, as they are definitions.
