WebBOD analysis is similar in function to chemical oxygen demand(COD) analysis, in that both measure the amount of organic compoundsin water. However, COD analysis is less specific, since it measures everything that can be chemically oxidized, rather than just levels of biologically oxidized organic matter. Background[edit] WebCOD versus BOD Like BOD, chemical oxygen demand (COD) can be used to estimate the amount of organic loading in a water sample. COD describes the amount of oxygen required to chemically breakdown the pollutants, while BOD indicates the amount of oxygen required to breakdown the pollutants, biologically with microorganisms.
