Air Pollution Management
Air Pollution:
It is the introduction of particulates, biological molecules, or other
harmful materials into Earth’s atmosphere, causing disease, death to
humans, damage to other living organisms such as food crops, or the
natural or built environment.

Sources of Air Pollution:
Air Pollutants is categorized in to
• Primary Air Pollutants
• Secondary Air Pollutants
Primary Air Pollutants: Materials that when released pose health risks in their unmodified forms
or those emitted directly from identifiable sources. Five major materials released directly into the
atmosphere in unmodified forms.
• Carbon monoxide • Nitrogen Oxides • Particulate matter
• Sulfur dioxide • Hydrocarbons

Sources of Air Pollution:
Secondary Air Pollutants:
Primary Pollutants interact with one
another, sunlight, or natural gases
to produce new, harmful
compounds.
• Ozone • Photochemical Smog
• PAN (Peroxy Acetyl Nitrate) • Aerosols and mists (H2SO4)

Environmental Impact
Acid Rain:
Acid rain is the result of the emissions of sulfate
and nitrates into the atmosphere from the burning
coal to produce electricity and deposited to the
earth surfaces as an acid.

Ozone Depletion
• The Ozone layer is a thin layer in the atmosphere made up of oxygen atoms (03)
that absorb harmful ultraviolet radiation (UV-B) from reaching the earth’s surface.
• The ozone is being depleted by chemicals released into the atmosphere like
chlorofluoromethanes (aerosol repellents and as refrigerants).
• One free chlorine atom will destroy 100,000 ozone molecules before it dies off.

Global Warming
Global warming is the result of the troposphere trapping heat causing a greenhouse
effect.

Air Pollution Management
It is a phenomenon in which
the atmosphere of a planet
traps radiation emitted by its
sun, caused by gases such as
carbon dioxide, water vapour
and methane that allow
incoming sunlight to pass
through but retain heat
radiated back from the
planet’s surface.
