dellossigeno

Dellossigeno denotes processes or conditions related to the loss or removal of oxygen from a system. In scientific use it corresponds to deoxygenation or oxygen depletion and appears across chemistry, environmental science, biology, and industry. It can refer to dissolved oxygen in liquids as well as oxygen bound in materials or tissues.

In chemistry and materials science, deoxygenation removes oxygen from liquids, gases, or solids to prevent oxidation and corrosion. Common methods include chemical reducing agents, vacuum degassing, and purging with inert gases such as nitrogen or argon. Controlled deoxygenation preserves reactivity and stability in fuels, polymers, and metal treatments.

In aquatic environments, deoxygenation describes a drop in dissolved oxygen (DO) due to stratification, nutrient enrichment, or high microbial respiration. Low DO creates hypoxic or anoxic waters, harming aquatic life and triggering dead zones. DO is routinely measured in mg/L to assess ecosystem health.

Biology and medicine use hypoxia to denote tissue oxygen loss, arising from impaired circulation, respiratory failure, or anemia. Acute hypoxia is a medical emergency, while chronic hypoxia activates cellular responses (e.g., hypoxia-inducible factors) and can influence prognosis and treatment.

In food packaging and storage, deoxygenation reduces spoilage by removing or replacing oxygen with inert gas, such as nitrogen, or by vacuum sealing. This slows oxidation, flavor loss, and microbial growth.
