oxygenation
Definition
Oxygenised is a term that is used to describe a substance that has oxygen added to it. This can be done in a variety of ways, such as by bubbling air through the substance, or by adding a chemical that releases oxygen into the substance.
Oxygenation is a chemical process that involves the addition of oxygen to a substance. This process can be used to improve the properties of the substance, such as its solubility, its reactivity, or its taste.
Oxygenation is used in a variety of industries, including the food industry, the pharmaceutical industry, and the water treatment industry. For example, oxygenised water is often used in spas and swimming pools, as it is believed to have health benefits.
Here are some examples of substances that can be oxygenised:
- Water
- Food
- Medicines
- Fuels
- Chemicals
How can the word be used?
Oxygenation is used in many different medical procedures, such as CPR and the treatment of carbon monoxide poisoning.
Different forms of the word
Noun: The process of adding oxygen to something.
Adjective: Relating to the addition of oxygen.
Etymology
The word "oxygenation" comes from the Latin word "oxygenium" (oxygen) and the suffix "-ation," which means "the act of.".
The word "oxygenation" was first used in English in the 19th century. It was used to refer to the process of adding oxygen to something.
Question
Why is oxygenation important?
AQA Science Exam Question and Answer
Question:
Explain the concept of oxygenation in aquatic environments and its significance for aquatic life. Provide a specific example of how oxygenation can be altered and its potential impact on aquatic ecosystems.
Answer:
Oxygenation refers to the process of introducing or increasing the concentration of dissolved oxygen in aquatic environments, such as rivers, lakes, and oceans. This oxygen is essential for the survival of aquatic life, including fish and other organisms. Oxygen enters the water through diffusion from the atmosphere and through photosynthesis by aquatic plants.
For instance, consider a freshwater pond. Aquatic plants produce oxygen during photosynthesis, and this oxygen dissolves into the water, creating a suitable habitat for fish and other organisms. However, factors like pollution, eutrophication (excessive nutrient enrichment), and temperature changes can alter oxygen levels. Eutrophication, often caused by excessive nutrient runoff from agricultural areas, leads to algal blooms that consume oxygen during decomposition. This can result in oxygen-depleted areas known as dead zones, where aquatic life struggles to survive.
Oxygenation is crucial for maintaining the health and balance of aquatic ecosystems. It supports the respiration of aquatic organisms and ensures the breakdown of organic matter without depleting oxygen levels excessively. Proper management of human activities and the mitigation of pollution are essential to preserving oxygenation and the vitality of aquatic ecosystems.
