OXYGEN DEPLETION

Oxygen depletion is the reduction of the dissolved oxygen level in a water body. The main reason for the occurence of oxygen depletion within a water source is due to elevated levels of algae and the growth in phytoplankton levels which is brought from greater concentrations of nitrogen and phosphorus. The organisms resulting from photosynthesis take up more oxygen during the night time and work in incorporating active photosynthesis through respiration.
