Oxygen in Liquids (DISSOLVED OXYGEN) Dissolved Oxygen – the amount of dissolved oxygen in a body of water as an indication of the degree of the health of water and its ability to support a balanced aquatic ecosystem. Concentration, usually expressed as a weight/ volume relationship such as milligrams per liter, at saturation decreases with increasing water temperature and salinity (Table 1), and also as barometric pressure falls Dr. Oxygen enters the water through the process of diffusion from the atmosphere (direct absorption), through aeration by rapid movement as well as photosynthesis by aquatic plants. 4 Dissolved oxygen is one of the best indicators of the health of a water ecosystem. Since many living organisms require oxygen to survive, it is a necessary component of water systems such as streams, lakes, and rivers in order to support aquatic life. The research is mainly focused on the rate of growth of such cities and availability of natural resources to sustain the growth (Xu et al.

DO is an important parameter in assessing water quality because of its influence on the organisms living within a body of water Dissolved oxygen = (mL/L) Notice that the unit is one milliliter of oxygen per litre of water, which can also be transferred into mg per litre. A dissolved oxygen level that is too high or too low can harm aquatic life and affect water quality. Add 1 cm3 of manganese (II) sulphate solution to the sample using a pipette.
