Classify pollutants based on the source, state, polluted area and location with suitable examples. Explain the concept of primary and secondary pollutants. Explain the concept of source-transport receptor approach for pollution management.

Pollutants are undesirable substances introduced into the natural environment, causing adverse changes and affecting the health of ecosystems and organisms, including humans. Environmental pollution, control, and management involve understanding the nature and behavior of pollutants to effectively mitigate their impact. To facilitate this, pollutants can be classified on the basis of various criteria, including their source, physical state, area of pollution, and location. Furthermore, the distinction between primary and secondary pollutants and the adoption of strategic models like the source-transport-receptor approach play significant roles in pollution control and management.

### Classification of Pollutants

#### 1. Based on Source

Pollutants can be classified based on whether their source is identifiable or diffused:

a. Point Source Pollutants:
These originate from a single, identifiable source, such as a factory smokestack or sewage discharge pipe. Examples include:
- Industrial effluents released from a chemical plant
- Wastewater from a sewage treatment plant
- Emissions from a thermal power plant

b. Non-point Source Pollutants:
These come from dispersed sources, often difficult to identify and control. Examples include:
- Pesticides and fertilizers runoff from agricultural fields
