The normal atmosphere is composed approximately of 20.9% oxygen, 78.1% nitrogen, and 1% argon with small amounts of various other gases. Decreased oxygen levels (below the atmospheric level of 20.9% by volume) can cause various effects including: Level of 17%: increased breathing volume and accelerated heartbeat

Face masks restrict oxygen intake. Worksafe safety requirements state fitted face masks with oxygen restrictions below 70% oxygen are dangerous. to workers. Tests on fitted face masks show oxygen levels as low as 10%. causing. hypoxia (oxygen deprivation) leading to dizziness, headaches, loss of consciousness or, in severe cases, death.

Dissolved oxygen is one of many measures of water quality, but an important one for aquatic life. Like land animals, fish and shellfish require oxygen to survive. When oxygen levels fall below 5 mg/l, fish are stressed. At oxygen levels of 1–2 mg/l, fish die.

Oxygen must be supplied to the enclosed volume to maintain the DO above 7mg/litre (7 ppm) and between 90% - 120% saturation. Treatment should be aborted if the oxygen is falling rapidly below 60% saturation or 4.5mg/litre, and can't be immediately recovered.

3. Dissolved oxygen levels higher near surface due to photosynthesis in this area. 4. O2 levels are lower in deeper, dark layers due to aerobic respiration and because less O2 gas dissolves in deeper and colder water. 5. Open oceans tend to have limited amounts of nitrates, phosphates, iron, and other nutrients that limit productivity. 6.

Dissolved oxygen levels are higher near the surface due to photosynthesis in this area. CO2 levels are lower near the surface and higher in deeper, darker layers due to aerobic respiration. Open oceans tend to have limited amounts of nitrates, phosphates, iron, and other nutrients that limit productivity.
