Biochemical oxygen demand - Wikipedia
Biochemical oxygen demand - Wikipedia

Biochemical oxygen demand, (BOD) is the amount of dissolved oxygen (DO) needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 °C and is often used as a ...
