Spraying of pesticide is an example of

Options

A. Point source water pollution
B. Diffuse water pollution
C. Both (1) and (2)
D. Pyrolysis

Answer

**Step-by-Step Solution:**

1. **Understanding Pesticides**: Begin by defining what pesticides are. Pesticides are synthetic chemicals used in agriculture to protect crops from pests, diseases, and weeds.

2. **Application of Pesticides**: When pesticides are sprayed on crops, they can mix with the soil. This is an important aspect to consider as it leads to further environmental impacts.

3. **Contamination of Soil**: After application, pesticides can contaminate the soil. This is significant because it affects the soil quality and can have long-term effects on the ecosystem.

4. **Leaching into Groundwater**: Pesticides can leach from the soil into the groundwater. Leaching is the process by which soluble substances move through the soil and enter the groundwater supply.

5. **Definition of Diffusion in Water Pollution**: The movement of pesticides from the soil into the groundwater is an example of diffusion. In environmental science, diffusion refers to the spreading of pollutants in water.

6. **Understanding Water Pollution Types**: Differentiate between point source and diffuse water pollution. Point source pollution comes from a single identifiable source, while diffuse pollution comes from multiple sources and is spread over a large area.

7. **Conclusion**: Therefore, the spraying of pesticides is an example of diffuse water pollution, as the pollutants are not coming from a single point but rather spreading through the environment.

**Final Answer**: Spraying of pesticides is an example of diffuse water pollution.
