The answer to this question depends on the oxygen concentration that you are using and, to a degree, your body chemistry. Hal Watts has reportedly made many "bounce" dives on "air" (21% oxygen 79% nitrogen) in excess of 400 feet in sea water. Discounting the narcotic effect of nitrogen, ambient O2 or "air" becomes toxic at around 240 feet in salt water. You should never dive without proper training, and even properly trained Scuba divers would not dive beyond recreational limits (130 ft) without special training. Oxygen concentrations higher than 21%, or enriched air (Nitrox) will have MOD Maximum Operating Depths based upon the specific concentration of oxygen. 100% oxygen is dangerous below 20 feet and, unless you are trained in the use of military rebreathers, you should not be diving 100% oxygen. Technical divers frequently use concentrations of oxygen up to 100% for decompression in stage tanks, but they are not diving on oxygen. Many will undoubtedly realize that I am not distinguishing between 1.6 ATA and 2.0 ATA... Nor have I discussed the 24 hour clock and the cumulative effect of oxygen exposure. If you are still wanting to know the depth at which a specific concentration of oxygen or an exposure to oxygen over time can become toxic, you should take a class in Nitrox or enriched air from a internationally recognized SCUBA agency. Many questions will be answered and you will learn the formulas to determine oxygen toxicity for a given concentration. I hope this helps

What happens if you go in the Black Sea?
You might die because at a certain depth it becomes toxic
Why is nitrogen used in Nitrox?
Nitrox is just oxygen enriched air.If you used pure oxygen, it would be toxic past a depth of 20 feet / 6 meters.
What is carbon dioxide narcosis?
Carbon dioxide narcosis happens when people have too much oxygen. It builds up in the body and becomes toxic
Why can't we survive with only fermentation?
not enough ATP is produced for our bodies to function
What is oxygen Toxicity?
Toxic oxygen--.When oxygen is used by the body, most of it is converted to water. However, a small fraction of the oxygen breathed is converted to toxic oxygen. The body uses several different processes for preventing and repairing toxic-oxygen damage.
Is air conditioning coolant toxic?
Very toxic. Do not inhale, it deplets the oxygen.
Is sulfur hexachloride toxic if inhaled?
It is not toxic, extended inhalation can cause you to pass out if you do not have oxygen.
Can too much oxygen be toxic?
Yes it can.
How deep can a human dive without being crushed?
The biggest challenges is oxygen and nitrogen concentration. Oxygen becomes toxic at two atmospheres or about 300 feet since it is 1/5 atmosphere at the surface. Nitrogen is dangerous at lower concentrations if the diver doesn't rise very slowly. It also become like a narcotic about that depth. It is possible to regulate the concentration and use helium and selected gases and you can go down to at least about 1500 feet.
Is lactic acid a hazardous substance?
In quantities over a certain level, lactic acid is toxic; this is why lactic acid is broken down after its formation, once sufficient oxygen is available.
What happens when we throw toxic substance in river and stream?
it becomes
Are hydrogen and helium and oxygen poisonous?
Hydrogen and helium are generally considered non-toxic since they don't react with our bodies and are not harmful when inhaled or ingested in small amounts. Oxygen, on the other hand, is essential for human life and is not toxic in normal concentrations. However, excessively high levels of oxygen (such as in pure oxygen environments) can be toxic and potentially cause harm.
