1. the process of removing oxygen from a substance or environment
Usage: commonly used in chemistry, biology, and environmental science
2. the reduction or depletion of dissolved oxygen in water, especially in aquatic ecosystems
Usage: environmental science context

Examples

• The deoxygenation of the lake led to a decline in fish populations.
• Industrial processes often require deoxygenation of water to prevent corrosion.
• Climate change is accelerating deoxygenation in coastal marine environments.
• The laboratory performed deoxygenation of the sample using nitrogen gas.
• Deoxygenation of blood occurs when hemoglobin releases oxygen to tissues.
• Stagnant water undergoes deoxygenation as microorganisms consume available oxygen.
