Abstract
Currently there is much emphasis placed upon water quality and maintaining
water quality parameters in our freshwater hydrosphere. One of the most widely cited
parameters is that of dissolved oxygen concentration (DO). DO is often used as an
indicator of the quality of water for, use by humans as well as habitat for aquatic flora
and fauna, and is maintained by many natural chemical and biochemical processes
which either increase or decrease local oxygen concentrations. Respiration by aquatic
life serves to reduce DO, as does biodegradation of organic material in the sediments,
along with a host of other oxygen consuming chemical reactions. Photosynthesis by
aquatic plant life can be a significant source of oxygen to a water body, as can oxygen
mass transfer with the atmosphere. In nature these processes result in balanced DO
concentrations, allowing for seasonal changes, in surface waters.
