How does temperature impact dissolved oxygen
WebAs the temperature of the water increases, dissolved oxygen levels decrease. Increases in pathogens, nutrients and invasive species. Increases in concentrations of some pollutants such as ammonia and pentachlorophenol due to their chemical response to warmer temperatures. Increase in algal blooms (Photo of algal blooms). WebJan 14, 2024 · How does temperature affect dissolved oxygen. As the temperature increases, the oxygen content gradually decreases. In freshwater, dissolved oxygen mainly comes from two parts: one is the oxygen released by plant photosynthesis, accounting for about 60%. Another part is that the oxygen in the air dissolves in water, accounting for …
