Biochemical Oxygen Demand (BOD) Biochemical Oxygen Demand‚ BOD‚ as it is commonly abbreviated‚ is one of the most important and useful parameters (measured characteristics) indicating the organic strength of a wastewater. BOD measurement permits an estimate of the waste strength in terms of the amount of dissolved oxygen required to break down the wastewater. The specifics of the analysis are discussed in detail in Standard Methods for the Examination of Water and Wastewater. The BOD test is
