Question

The medium which interacts with the long-lived pollutant is :

A) Sink B) Receptor C) Source

• A. A
• B. B and C
• C. A and C
• D. A, B and C

Answer 1

The correct option is A A

The source is the main cause of pollution. It is from where the pollutants come.

The receptor is the medium that is affected by a pollutant. Photochemical smog causes irritation of eyes and respiratory tract. Thus, man acts as a receptor for the photochemical smog.

The sink is the medium which interacts with the long-lived pollutant and removes pollution. For example, the sink for a sulphuric acid pollutant is a marble wall which reacts and gets damaged.

$H_2{SO}_4+{CaCO}_3\to {CaSO}_4+H_{2}O+{CO}_2$

Hence, the correct option is $\text{A}$
