Significance of Biological Oxygen Demand
Biological Oxygen Demand (BOD) is a crucial metric that measures the amount of oxygen consumed by microorganisms while decomposing organic matter in water. This indicator reflects the level of organic pollution, providing insight into water quality and potential pollution levels. Higher BOD values indicate greater pollution, with standard permissible limits often established for industrial effluents. The observed BOD values can significantly exceed these limits, highlighting the need for effective wastewater treatment to reduce organic pollution in aquatic environments.

The concept of Biological Oxygen Demand in scientific sources
Biological Oxygen Demand (BOD) is a crucial indicator of water quality, measuring the oxygen needed by microorganisms to decompose organic matter, thus reflecting the level of organic pollution in aquatic environments.

(1) It is a principal wastewater treatment technologies employed at the facility for treating (BOD).[1] (2) It indicates a decrease in the amount of oxygen consumed by aerobic biological organisms to decompose organic matter, potentially leading to anaerobic conditions.[2] (3) Biological Oxygen Demand of water discharged from POME pond has been selected as the performance measure for water quality control in this framework due to its common application and robustness in measuring pollution caused by both organic and inorganic matter.[3] (4) "Biological oxygen demand", abbreviated as BOD 5, is listed as an abbreviation, and represents the amount of oxygen needed by microorganisms to decompose organic matter.[4] (5) Chemical oxygen demand (COD), "biological oxygen demand" (BOD 5 ), organic matter (OM), total organic carbon (TOC), suspended solid (SS), nitrate (NO 3 − ), and absorbable organic halide (AOX) were analyzed using a portable UV analyzer.[5]

(1) Is the amount of oxygen consumed by microorganisms to decompose organic matter in water, reflecting the level of organic pollution.[6] (2) Biological oxygen demand (BOD5) is a measure of organic matter in water samples, and the removal efficiencies of BOD5 in greywater treated by a constructed wetland are being analyzed.[7] (3) This is a water quality parameter, and the measured value for an increase is limited due to the production and death of algae, making it difficult to simulate a large-scale river.[8]
