Statement 1 is correct but statement 2 is incorrect
Statement 1 is incorrect but statement 2 is correct
Both statements 1 and 2 are incorrect
Answer :
A
Solution :
BOD
(biochemical oxygen demand) refers to the amount of the oxygen that would be consumed if all the organic matter in one litre of water were oxidised by bacteria. The BOD
test measures the rate of update of oxygen by microorganisms in a sample of water and thus, indirectly BOD
is the measure of the organic matter present in the water. The greater the BOD
of wastwater, more is its pollulting potential.
