What is bod meaning?

BOD is an acronym for Biochemical Oxygen Demand, which is a measure of the amount of oxygen consumed by microorganisms in water while they break down organic matter. It is used as a parameter for evaluating the quality of water in terms of its organic content, and as an indicator of the presence of organic pollutants that can lead to eutrophication, algal blooms, and loss of aquatic life. Higher BOD values indicate that organic matter is being decomposed, which can deplete the oxygen content of the water and make it unsuitable for aquatic life. BOD can be used in conjunction with other water quality parameters to assess whether a body of water is suitable for drinking, irrigation, and other uses.
