Pulmonary Oxygen Toxicity (PO) and Central Nervous System Toxicity (CNS)
Abnormally slow breathing is a symptom of oxygen toxicity
Pulmonary oxygen toxicity is caused by divers exposing themselves to elevated partial pressures of oxygen for long periods of time, and is primarily a concern for technical divers who decompress on oxygen. Pulmonary oxygen toxicity causes a burning sensation in the trachea, coughing, shortness of breath, and eventually lung failure.
Cells resist oxygen toxicity because of the semi permeable membrane. This controls the amount of molecules and what molecules enter the cell.
Oxygen toxicity.
Partial pressure of oxygen of 1.6 will cause toxicity. If using standard air (roughly 20% O2) this equates to a pressure of 8 bar which is present at 70m. In terms of the percentage of O2 which causes toxicity, it depends on the depth but a partial pressure of 1.6 bar is the toxicity threshold
The signs and symptoms for oxygen toxicity include changes in vision, nausea, twitching, and dizziness. More serious symptoms can include seizures and possible death.
Oxygen toxicity can cause seizures and spasms. That implies to me that flickering eyes may be a symptom of O2 toxicity, but not a common or likely one. While possible, I'd personally look elsewhere for the cause.
Oxygen is very reactive and causes things to oxidize. This includes the genetic material of your cells which is one of the reasons why people get old.
once again...this question CANNOT be answered as is, it needs to be more specific. -are you asking about oral, demal or inhalation toxicity? -are you asking about acute toxicity, chronic toxicity, or carcinogenic toxicity? -if asking about acute toxicity, are you asking about slightly toxic, moderately toxic, or highly toxic? -what is the context: mineral collection, stone carving, or mining?
Examples of chemical properties: flammability, reaction with oxygen, valence, toxicity, stability, electronegativity etc.
A bacterium that needs oxygen is called an aerobic bacterium
