๏The presence or introduction of any foreign
material in the air ,which can cause change in
the original composition.
๏ It can cause discomfort ,hazardous damage
to the environment, human being & other
living organisms.

Sources of air pollution
1. Natural Sources
๏ง Dust from natural source
๏ง Smoke and carbon
monoxide from wildfires
๏ง Volcanic activities produces
sulfur and ash contents.
2. Anthropogenic (man-
made) sources
๏ง Point Source.
๏ง Area Source.
๏ง Line Source.

๏ A Primary pollutant is an air pollutant emitted directly from
a source.
๏ The majority of them includes:-
Sulphur oxides (SOx)
Nitrogen oxides (NOx)
Carbon monoxide (CO)
Volatile organic compounds (VOC)
Particulates
Persistent free radicals
Toxic metals, ( lead and mercury,).
Primary Pollutants

๏ Secondary Pollutants are formed when primary pollutants
emitted directly from a combustion process react in the
atmosphere.
๏ The majority of them includes:-
Smog
Ground level ozone (O3)
Peroxyacyl nitrates (PAN)
Secondary Pollutants

8. ๏
๏ Pollutants are the unwanted suspended particle or waste
materials in the atmosphere that cause air pollution.
๏ Permissible limits of pollutants.
1. Carbon monoxide :- 9 ppm.
2. Nitrogen Dioxide :- 100 ppb.
3. Ozone :- 0.070 ppm.
4. Arsenic:- 6 ppb.
5. Nickel :- 20 ppb.

๏ Carbon credit is a generic term for any tradable
certificate or permit representing the right to emit
one ton of carbon dioxide or the mass of another
Greenhouse gas with a carbon dioxide equivalent to
1 ton of carbon dioxide.
๏ Certificate issued to countries those reduce the
emission of greenhouse gases(GHG) which causes
global warming
CARBON CREDIT

๏ Came into existence as a
result of increasing
awareness of Need for
controlling emission
๏ The carbon footprint is a
measurement of all
greenhouse gases we
individually produce
and has units of kg of
carbon dioxide
equivalent

11. ๏
๏ A carbon footprint is a measure of the impact
activities have on the environment and in particular
climate change.It relates to the amount of
greenhouse gases produced in our day-to-day lives
through burning fossil fuels for electricity ; heating
and transportations;etc

What is a carbon
footprint ?
12. ๏
๏ Carbon footprint is "The
total set of greenhouse
gases emission caused
by an organisation ;
event ; product or
person"
๏ Greenhouse gases can be
emitted through
transport land clearance
and the production and
consumption of fuel and
fuels
12
13. ๏
๏ Increase Greenhouse gas and arerosol concentrations
๏ Changes in temperature
๏ Increasing sea level
๏ Various bacterial growth
๏ Health hazard

Global issues related to
pollution
14. ๏
๏ The heath of the public, especially those who are most
vulnerable is at risk from air pollution.
๏ Local authorities should take action to assess and improve
local air quality .
๏ Alternatives should be provided to all ,which pose a risk of
air pollution.
