Q-Consider the following statements:
  1. The Biological Oxygen Demand (BOD) is the measure of organic matter present in the water.
  2. Greater the BOD, lesser is the polluting potential.
  3. Microbes in sewage treatment plants increase the BOD of the effluent.
Select the In-correct answer using the code given below:
 A-Only 1,2
B- Only 2,3
C- Only 3
D-Only 2
MCQ Source- https://data.gov.in/keywords/biochemical-oxygen-demand
Ans-B
Greater the BOD more is the polluting potential. Actually, in secondary treatment or biological treatment of sewage water in plant, the primary effluent is passed into large aeration tanks where it is constantly agitated mechanically and air is pumped into it. This allows vigorous growth of useful aerobic microbes into flocs (masses of bacteria associated with fungal filaments to form mesh like structures).
While growing, these microbes consume the major part of the organic matter in the effluent. This significantly reduces the BOD (Biochemical Oxygen Demand) of the effluent. BOD refers to the amount of the oxygen that would be consumed if all the organic matter in one litre of water were oxidized by bacteria. The sewage water is treated
till the BOD is reduced.
Q-Consider the following statements:
  1. Kyoto Protocol was adopted in 1997 to fight global warming by reducing Greenhouse Gases emission.

  3. Both developed and Developing countries have mandatory mitigation obligations under the Kyoto Protocol.
