CONSTITUTION:Any solution having dissolved hydrogen peroxide in water may be used as an aqueous solution of hydrogen peroxide as a raw material and concentration of the aqueous solution is determined by calculation from saturated concentration of oxygen in water. For example, when the reaction is ...
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...

Dissolved Oxygen (DO).Oxygen is a product of photosynthesis, and in a balanced diurnal cycle of photosynthesis and respiration, algae generate adn consume oxygen, respectively. Meanwhile other organisms consume oxygen around the clock. During the early and peak growth phases of an HAB, DO can inc...

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...
A systematic investigation was carried out to explore the effects of the dissolved oxygen concentrations of micro-nano bubble water and biochar application amounts on the soil aeration, cucumber yield, and quality over two growing seasons (1st and 2nd crop). The results indicate that the dissolved...
