2. Definition:
Air pollution occurs due to the presence of undesirable solid / gaseous particles in
air,in quantities that are harmful to the human health and the environment.
TYPES AND SOURCES:
Primary pollutants: Pollutants that are emitted directly from identifiable
sources are produced bothby natural events (dust storms & volcanic eruption)and
by human activities (emission from vehicles and industries) are called primary
pollutants.
Primary pollutants as follows
 Carbon oxides
 Nitrogen oxides
 Sulfur oxides
 Volatile organic compounds (Mostly hydrocarbons)
 Suspended particulate matter
Secondarypollutants: The pollutants produced in the atmosphere when certain
chemicalreactiontakes place among the primary pollutants are called
secondarypollutant.
It includes
 sulfuric acid
 Nitric acid
 Carbonic acid

3. DIFFERENT SOURCES OF AIR POLLUTION

4. Particulates suchas
 Dust-Aerosolcontaining solid particles that are blown into air/
produced from larger particles by grinding
 Smoke-Containing solid particles /liquid produced due to chemical
reaction
 Mist –Aerosolconsisting ofliquid droplets
 Fog-Aerosolconsisting of waterdroplets
 Smog- Smoke + fog

6. Industrial pollution
Domestic air pollution in olden time ( Smoke)

10. CONTROLMEASURES FOR AIR POLLUTION:
To have proper equipment in place.
This includes device for removal of pollutants from the flue gases through
scrubbers , closed collection recovery systems(Through which it is possible to
collect the pollutants before they escape).
Plant tree and avoid deforestation
Preventive
techniques
Effluent
Control

14. Conclusion:
 Air pollution is a major environment relatedhealth threat to children
and risk factorfor both acute and chronic respiratory disease. To
prevent this problem need to actionby government and also increase
awarenessamong people.
 A method that seeksto develop as many options as possible, To reduce
environment harm and cost.
 Save environment for sustainable life.
