Oxygen – Introduction, Oxygen Conversion, Dissolved Oxygen, and More

Oxygen

Oxygen is a colorless and odorless gas. The gas is very reactive and binds to other elements in the form of oxides. Oxygen is present in the air at 20.9 vol. %.

Oxygen is widely used in the steel and metallurgy industry. It plays an oxidizing role in the purification of domestic wastewater and is used in the form of ozone (O 3 ) in the remediation of contaminated soils. Most combustion processes (chemical industry) are carried out with oxygen.

How does it Influence Aquatic Biodiversity?

It is not only in terrestrial ecosystems that oxygen is an important element. It is also crucial for many chemical and biological processes that occur in waterways.

• These are mainly:
  Respiration and therefore metabolic efficiency, growth, disease resistance, etc. ;
• The decomposition of organic matter;
• The transformation of chemical compounds into less dangerous forms.
• In addition, a low level of dissolved oxygen can have effects on the ecology of the environment and the relationships between living beings. One of the consequences is the decrease in diversity: only species resistant to low oxygen levels are found on this site.
• People’s behavior is changed. They reduce their activities, delay their migration, etc. Their relationships with other species are also affected (eg predator-prey and parasite-host relationships).

What Factors Influence Dissolved Oxygen?

The level of dissolved oxygen varies mainly according to the following natural factors:

• The water temperature. Cold water contains more dissolved oxygen than warm water. To learn more about the relationship between dissolved oxygen and temperature, see the temperature capsule.
• The degree of turbulence. Heavy mixing increases the contact between air and water and therefore increases the surface area on which the oxygen in the air can dissolve.
• The respiration of animals, plants (at night) and bacteria that degrade organic matter. By breathing, living beings consume oxygen which decreases the amount of dissolved oxygen available.
• The photosynthesis of plants and algae produces oxygen during the day.
  partial gas pressure. The higher the pressure, the greater the solubility of gases.

Conclusion

Oxygen is one of the gases that is naturally found dissolved in water.
