BOB means biological Oxygen Demand , more the polluted water , more oxygen will b required by FLOC that is Bacteria and Fungi to oxidise and digest the organic matter
BOD will b lower when no sewage and industrial waste disposal is done in river
it could have both positive and negative effect on aquatic life
if wastes are organic, they get fodder but if same waste is in excess , alga colonises the water leading to EUTROPICATION will results in death of Fishes etc
on the other hand if wastes are Radioactive or inorganic, it will adversely affects them
