High levels of organic and inorganic materials in wastewater result in High levels of biochemical oxygen demand (bod).
The amount of dissolved oxygen required by aerobic biological organisms to break down organic material present in a given water sample at a particular temperature over a certain time period is referred to as biochemical oxygen demand.
The higher the BOD, the faster oxygen is reduced in the stream. This means that higher-level aquatic life has less oxygen content to it.. High BOD levels have the same consequences as low dissolved oxygen levels: aquatic creatures become stressed, suffocate, and die.
So, the more organic contaminants there are in the water, the more oxygen the bacteria demand, and this oxygen requirement is known as BOD. As a result, the amount of pollution in a body of water is exactly proportional to the BOD.
