WebBOD is a measure of the amount of oxygen that is required by microorganisms to break down organic matter in water. In other words, it is a measure of how much oxygen is needed to support life in a body of water. The higher the BOD, the more polluted the water is, as it means that there are more organic pollutants present that need to be broken ... Webenters a system faster than it can be degraded, dissolved oxygen levels can drop below the minimum level required by aquatic organisms. In extreme cases, all of the dissolved oxygen may be removed, making the stream “anoxic”. When this happens, most organisms die, thus adding more BOD to the system and further increasing the oxygen demand.
Web14 de nov. de 2024 · Oxygen exists in many forms, in which dissolved oxygen is dissolved in dissolved oxygen, which could be mainly produced by photosynthesis of green plants in the water (Doudoroff, 1970).
