While the BOD test is a valuable tool, it has certain limitations:
Time-Consuming: The standard BOD test requires a five-day incubation period, which may delay decision-making in environmental management. Non-Specific: BOD does not identify specific pollutants or their concentrations; it only measures the overall effect of organic matter on oxygen demand. Interference: The presence of certain chemicals or toxic substances can interfere with the test, leading to inaccurate results.
