What is Air Pollution

A normal healthy person takes breathe nearly 11000 litres of Air in a Day. Roughly 12-20 breathe per minute over the course of a day, that ends upto 17000-22000 breathe per day or more. A respiration rate which is under 12 or above 25 per minute is a sign of an Underlying health concerns. The rate is calculated by how many times the chest rises per minute when a person is at rest conditions.

Think how much Oxygen you are inhale per day? Normally the composition of Air approximately 78% nitrogen, 21% Oxygen, 1% Argon, and trace percentages of other gases. Such as Carbon dioxide, methane, Ozone, Ammonia, Helium, Sulfur, Nitrogen dioxide, Iodine etc. 

While breathing , The amount of inhale air contains 21% Oxygen, and 0.04% Carbon dioxide, the amount of breathe out air contains 16.4% Oxygen and 4.4% Carbon dioxide. This is because the trillions of cells in our body use Oxygen to breakdown molecules absorbed from the food we eat, to release energy and give out Carbon dioxide by products.

Breathing is the rhythmical process of moving air into and out of the Lungs. Mostly to flush out (exhalation) Carbon dioxide and bring in(inhalation) Oxygen in our body. Most of us we never think too much about Breathing, Because it is invisible, it is something that we can't see, we can feel it. But it is the time to think about it. Most people are unaware that according to World Health Organizations(WHO), more than 90% of the population breaths Polluted Air.

"Air Pollution is caused by when solid and liquid particles and certain gases and chemicals that are suspended in the Air. In one word Air pollution is the mixing of foreign substances into the whole atmospheric air."
