Question

What is BOD?

Hint:

BOD is commonly used to assess the organic pollution level in wastewater and surface water bodies.

Answer 1

Step 1: Understanding BOD.
BOD stands for **Biochemical Oxygen Demand**. It is a measure of the amount of oxygen required by microorganisms to break down organic material in water. A higher BOD indicates a higher level of pollution in water, as more oxygen is needed for microbial activity.

Step 2: Conclusion.
BOD is an important parameter for assessing the quality of water and its level of contamination.
