Some common particulate matter in the air: sea salt (from ocean spray), mineral dust, ash, pollen, tiny droplets (aerosols) of fuels and chemicals and tiny bits of plants, animals and minerals.
Inhaling some of them can lead to Asthma, lung cancer and heart disease.
Composition of air:
Nitrogen: ~76.4%
Oxygen: ~20.5%
Water vapor: 2%
Argon: 0.91%
Carbon dioxide: .04%
Note that the water vapor content of air varies depending on the weather and climate. It may range from nearly 0% in deserts to more than 4% in tropical areas.
It contains 78% of nitrogen, 21% of oxygen, 0.93% of argon, 0.03% of carbon dioxide and 0.04% of others:)
No, carbon dioxide is also found in air.
Methane Co2 Hydrogen Helium etc
argon

The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
Oxygen because when something hits oxygen it tends to rust so therefore it changes it's color.
nitrogen and oxygen
argon
there are many other gases like nitrogen, helium and water vapour in the air
carbon dioxide which is used to process plants and trees which let off oxygen
The percentage of oxygen in the atmosphere is 20.75%. The atmosphere has many other elements that we breathe in besides oxygen. Oxygen needs to be present for life on earth.
we take in oxygen via the air. the air is made up of 21% oxygen and oxygen is produced by many things. our lungs intake the air. through the mouth and nose.
Oxygen makes up about 21% or approximately 1/5 of the air.
As the third most abundant element, oxygen in the air is made by plants and algae.
Air is mostly made up of nitrogen. Oxygen is the second largest amount in air. Carbon dioxide is the third largest amount in air. Hope this helps!
the earth air is made of air, oxygen, water and helium
Nitrogen 78%, as oxygen is about 20% the rest is made up of small amounts of argon, carbon dioxide, methane and other gases. In areas of high pollution, for exmple cities, there will be sulfur oxides, nitrogen oxides and particulates from combustion.
its air dry made up of oxygen...
It is normally know as 'air' and air is made up mostly of nitrogen and oxygen. Oxygen is the gas that the body needs to survive.
