Biological Oxygen Demand (BOD)
Biological Oxygen Demand (BOD) measures the amount of oxygen required by microorganisms to decompose organic matter in water over a specified period. It serves as an indicator of water quality; higher BOD levels signify more organic pollution, which can lead to oxygen depletion in aquatic environments, harming fish and other aquatic life. Monitoring BOD helps assess the effectiveness of wastewater treatment and the pollution load in rivers and lakes, guiding efforts to maintain healthy ecosystems. In essence, BOD reflects the overall health of a water body and its ability to support life.
