Abstract
In order to quantify the effect of religious activity in water pollution, an ex situ study for Ganesh idol immersion has been carried out and dissolved oxygen (DO) and biochemical oxygen demand (BOD) were evaluated. The results showed an adverse impact on the water quality of the micro-environment of the idol immersion. The present investigation highlights the importance of analysis of the samples from water columns in the micro-environment of the idols after immersion and not the surface waters where the echelon of the effect gets diluted.
