Question

    What is a key advantage of Chemical Oxygen Demand (COD) over Biochemical Oxygen Demand (BOD) in water analysis?

    A COD measures biodegradable substances more accurately. Correct Answer Incorrect Answer
    B COD requires a shorter testing time. Correct Answer Incorrect Answer
    C COD correlates consistently with BOD measurements. Correct Answer Incorrect Answer
    D COD measures dissolved oxygen directly. Correct Answer Incorrect Answer

    Solution

    COD test results are available in a shorter time frame (around 2 hours) compared to the standard BOD test, which takes 5 days, making COD advantageous for faster assessments of water quality.
