WebThe BOD of a water sample is a measure of the amount of oxygen that used up by microorganisms in the sample over a five-day period. The higher the BOD of a water sample, the greater the amount of organic material present in the water and the greater the potential for water pollution. WebBiochemical oxygen demand (BOD, also called biological oxygen demand) is the amount of dissolved oxygen 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 (Kaiser, 1998 ).
WebSAMPLING AND SAMPLE HANDLING FOR BOD Water and wastewater samples are biologically active and the BOD will quickly deteriorate.
