2. DEFINITION:
 occurs when the air contains gases, dust,
fumes or odor in harmful amounts.
 it is when concentrated gases exceed safe
limits.
AIR POLLUTION

9. Air pollution occurs in many forms but can
generally be thought of as gaseous and
particulate contaminants that are present in the
earth's atmosphere. Gaseous pollutants include
sulfur dioxide (SO2), nitrogen oxides (NO), ozone
(O3), carbon monoxide (CO), volatile organic
compounds (VOC), hydrogen sulfide (H2S),
hydrogen fluoride (HF), and various gaseous
forms of metals.
These pollutants are emitted from large
stationary sources such as fossil fuel fired power
plants, smelters, industrial boilers, petroleum
refineries and manufacturing facilities as well as
from area and mobile sources.
They are corrosive to various materials which
causes damage to cultural resources, can cause
injury to ecosystems and organisms, aggravate
respiratory diseases, and reduce visibility.
ACCORDINGTO INDIAN PERSPECTIVE :

10. Primary pollutants are those which are emitted directly into the air from
pollution sources.
 Secondary pollutants are formed when primary pollutants undergo chemical
changes in the atmosphere.
• Ozone is an example of a secondary pollutant. It is formed when nitrogen
oxides (NO,) and volatile organic compounds (VOCs) are mixed and warmed
by sunlight.
• → Ozone (03) is a major component of what is often referred to as smog.
• →The ozone which is present in the troposphere, or the atmosphere that is
close to the ground, should not be confused with beneficial ozone that is
located in the stratosphere or upper atmosphere.This beneficial ozone in
the stratosphere helps protect the earth from harmful ultraviolet
light from the sun.

11. Government policies and initiatives to
control air pollution:-
Renewable energy:-
The government has set a target to
generate 40% of its total installed
power capacity from renewable
sources by 2030.
Electric mobility:- The
government has launched the
National Electric Mobility Mission
Plan to promote electric vehicles.
Afforestation:- The government
has launched the National
Afforestation Programme to
increase forest cover and reduce air
pollution.
