If BOD of water sample is very high, the sample is
Show Hint
BOD is directly proportional to the amount of organic matter in water. As organic matter increases, BOD increases, and Dissolved Oxygen (DO) decreases.
Step 1: BOD (Biochemical Oxygen Demand) is the amount of oxygen required by bacteria to decompose the organic matter in one liter of water. Step 2: A high BOD value indicates that there is a large amount of organic waste present, which requires more oxygen for breakdown. Step 3: Therefore, the higher the BOD of a water sample, the greater is its polluting potential.
