Question:
What do you mean by Biochemical Oxygen Demand (BOD)?

Answer:

Biochemical oxygen demand is the amount of oxygen required by bacteria to decompose organic matter in a certain volume of sample of water. Clean water would have a BOD value of less than 5 ppm, whereas highly polluted water has a BOD value of more than or equal to 17 ppm.
