What percent of oxygen is in the air?
21 percent
Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
Are there trees in Dubai?
The sandy desert surrounding the city supports wild grasses and occasional date palms. Several indigenous trees such as the Date palm and neem as well as imported trees like the eucalypts grow in Dubai’s natural parks.
What are the contents of air?
The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). Higher in the atmosphere air also contains ozone, helium and hydrogen.
Can we breathe pure oxygen?
Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can’t see properly, and your lungs, so you can’t breathe normally. So breathing pure oxygen is quite dangerous. Astronauts and deep-sea scuba divers sometimes breathe pure oxygen because they work in very dangerous places.
Can I make my own oxygen?
Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. This method is called electrolysis and produces very pure hydrogen and oxygen.

How do you measure oxygen in the air?
The Scripps Institute report oxygen measurements as changes in the O 2 /N 2 ratio of air relative to a reference. They compute: where (O 2 /N 2) sample is the O 2 /N 2 mole ratio of an air sample and (O 2 /N 2) reference is the O 2 /N 2 mole ratio of their reference.
What are the main causes of pollution in Dubai?
The widespread use of these exacts a large toll on pollutive output levels, causing the year round ambient readings to be higher than they should be. To reiterate, the main causes of pollution in Dubai are vehicular emissions as well as factories and other similar industries.
