Hi There,

BOD is defined as the amount of oxygen required by bacteria and other microorganisms to decompose organic matter present in a certain volume of water over a specific period.

It is an indicator of Water quality.

• High BOD levels indicate the presence of a large amount of organic pollutants in water, such as sewage or industrial effluents.
• Elevated BOD is often associated with a decrease in dissolved oxygen levels, which can negatively impact aquatic life.
