Atmosphere
Atmosphere is the ocean of air we live in, which is a homogenous mixture of gases.

Composition The atmosphere is the mixture of gases. So atmosphere is composed of different gases in Fig-1.
Nitrogen (N2) is 78.084%
Oxygen (O2) is 20.94%
Carbon dioxide (CO2) is 0.033%
Argon (Ar) is 0.93% and
All other gases are 0.0027%
Pollution
Any undesirable change in the air, soil and water which have an adversely effects on the human and environment is known as pollution.

Air Pollution Any undesirable particles either visible or invisible or gas found in the air, which is not the portion of the original and normal composition of the atmosphere is called air pollution.

Air pollution in marble industry
The marble industry can also release the dirty gases like NOX, SOX, COX and these dirty gas stream also contain particulate matters. To control these dirty gases some technologies are used to minimize such gases.

Cyclones The dirty gases come out from the marble industry in the chimney. If these dirty gases enter into the cyclone equipment through the inlet. These dirty gases are travel into the helical path. These gases have contain particulate matter. And these particles have more inertia
