Dissolved oxygen (DO) is one of the principal components which should be removed for the production of ultrapure water. Even though concentration of DO in water is very low (approximately 8 ppm under ambient co
However, smaller fish consume more oxygen per unit of body weight. Dissolved oxygen is usually measured in milligrams per liter (mg/L) or as a percentage (%) of oxygen saturation. Yet, in most aquaculture industries the amount of DO in water is reported in parts per million (ppm), 1 ...
Dissolved oxygen (DO) has long been recognized as a critical component of lake ecosystem structure and function (Hutchinson 1957, Wetzel 2001) and has been used as an indicator of lake ecosystem he...
Biologically speaking, however, the level of oxygen is a much more important measure of water quality than feacal coliform. Dissolved oxygen is absolutely essential for the survival of all aquatic organisms ( not only fish but also invertebrates suach as crabs, clams, zooplankton, etc). Moreover...
63, 64). The air-saturated water has a dissolved oxygen concentration of about 256 µM and its concentration is lower in alkaline water31. At the beginning of the reaction, the dissolved oxygen in both tubes was quickly depleted by reacting with LH22−. However, stirring replenishes the...

Water pollutionis another widespread activity with severe effects of freshwater invertebrates. Rivers and lakes often have been used for waste disposal. These wastes include sewage and other organic matter, the decomposition of which may reduce concentrations of dissolved oxygen to levels too low to su...
contain on average more cells (up to 1.4 × 107 mL−1) than younger groundwaters, challenging current estimates of subsurface cell abundances. We observe substantial concentrations of dissolved oxygen (0.52 ± 0.12 mg L−1[mean ± SE]; n = 57) in older ground...
Oxygen-demanding materialsmight be discharged from municipalwastewater treatmentplants, food-processing plants, breweries, as well as paper mills, compose one of the most important types of pollutants because these materials decompose in the watercourse, and can deplete the water of dissolved oxygen. ...
