Polymer Science Unit, Department of Biological Chemtstry, Indian Association for the Cultivation of science, Jadavpur, Calcutta-700 032 Manuscript received 30 November 1994, accepted 2 February 1995 A procedure for measuring BOD of collected water samples using a Karube type microbial BOD sensor is described. BOD of water samples collected from the Ganges at Calcutta, decreases on standing. This phenomenon has been attributed to consumption of the organic matter present in the collected sample
