Estimate the BOD for every dilution. The most exact BOD will probably be received from All those dilutions that have a depletion of no less than 2 mg/L DO and at least 1.
Microbial Interference: Some h2o samples may well have a high focus of organic or launched microorganisms that exhibit larger-than-common metabolic action. This can result in elevated BOD test values and an overestimation of the natural and organic pollution degree.
