“Reoxygenation experiments were also carried out to confirm the reversibility of the deoxygenation experiments.”

“This can in turn lead to blocked waterways and deoxygenation of the water, leading to the death of aquatic animals.”

“In aquatic systems, mobile sediments, organic matter and runoff of nutrients may cause localized algal blooms and areas of deoxygenation.”

“It is not clear whether the deoxygenations that have been reported to occur during suctioning with normal saline instillation were clinically significant.”
