3. WHAT IS AIR POLLUTION?
 Air pollution is the introduction of particulates, biological molecules,
or other harmful materials into the Earth's atmosphere, possibly
causing disease, death to humans, damage to other living organisms
such as food crops, or the natural or built environment.
 The atmosphere is a complex natural gaseous system that is
essential to support life on planet Earth. Stratospheric ozone
depletion due to air pollution has been recognized as a threat to
human health as well as to the Earth's ecosystems.
 Indoor air pollution and urban air quality are listed as two of the
world's worst toxic pollution problems in the 2008 Blacksmith
Institute World's Worst Polluted Places report. According to the
2014 WHO report, air pollution in 2012 caused the deaths of around 7
million people worldwide.

4. WHAT ARE THE CAUSES
OF AIR POLLUTION?
 Air pollution is caused mainly by Transportation, fuel
combustion in stationary sources, burning of fossil fuels like
coal, wood, dry grass, and construction activity.
 Motor vehicles produce high levels of Carbon Monoxide
(CO) and Hydrocarbons (HC) and Nitrogen Oxides (NO).
 Construction activities, bad roads and burning of fossil fuels
are responsible for Dust (particulate matter) Pollution.
 Residential and Commercial activities also contribute to Air
Pollution.

5. WHAT ARE THE EFFECTS
OF AIR POLLUTION?
 The human health affects due to poor Air Quality.
 Principally, air pollution affects the body's respiratory system and

 Though the individual reactions to air pollutants depend on the
type of pollutant a person is exposed to, the degree of exposure.
 Air pollution may cause long term health problems.
 The health effects caused by air pollutants may range from
biochemical and physiological changes like difficulty in
breathing, wheezing, coughing and aggravation of existing
respiratory and cardiac conditions.

6. HOW TO REDUCE AIR
POLLUTION?
