1. Statistical analysis
on
increase in air pollution
and
its effects
BY,
K.M.Bharthe

2. INTRODUCTION
Air pollution is the introduction of harmful substances
like chemicals,smoke etc into the atmosphere that causes
damage of the environment.

3. INTRODUCTION
A substance in the air that can be adverse to humans
and the environment is known as an air pollutant.
Pollutants can be in the form of solid particles, liquid
droplets, or gases. In addition, they may be natural or
man-made…
Some of the major pollutants are listed in the next slide

4. Sulphur oxides
Nitogen oxides
Carbon emmisions, especially CFCs
Particulates
Methane,Ammonia,Radioactive pollutants & Odors

5. How is it measured?
AQI (Air Quality Index) is the measure of air pollution
It indicates whether pollutant levels in air may cause
health concerns.
Ranges from 0 (least concern) to
500 (greatest concern)

6. Air Quality Air Quality Index Protect Your Health
Good 0-50 No health impacts are expected
when air quality is in this range.
Moderate 51-100 Unusually sensitive people should
consider limiting prolonged
outdoor exertion.
Unhealthy for
Sensitive Groups
101-150 Active children and adults, and
people with respiratory disease,
such as asthma, should limit
prolonged outdoor exertion.
Unhealthy 151-200 Active children and adults, and
people with respiratory disease,
such as asthma, should limit
prolonged outdoor exertion,
everyone else, especially children
should limit prolonged outdoor
excertion.
Very Unhealthy
(Alert)
201-300 Active children and adults, and
people with respiratory disease,
such as asthma, should limit
prolonged outdoor exertion
everyone else, especially children,
should limit outdoor exertion.

7. its harmful effects are…

9. The greenhouse effect is a process by which
thermal radiation from a planetary surface is
absorbed by atmospheric greenhouse
gases, and is re-radiated in all directions.
Since part of this re-radiation is back
towards the surface and the lower
atmosphere, it results in an elevation of the
average surface temperature above what it
would be in the absence of the gases

12. Steady Increase in
emmision of greenhouse
gases since 1990

13. amount of release of cArbon in tonnes
per person in various countries

16. Global warming is the rise in the average temperature of
Earth's atmosphere

25. PH scale of Ozone

26. Cycle of Ozone

28. death rates due to air
pollution

29. Some realistic facts and
statistics about air
pollution

30. Facts
We take in over 20 times more the acceptable level of air
pollution each day…
Breathing daily air pollution is like smoking 20
cigarettes a day…
Emissions from power plants contribute to over 2,800
lung cancer deaths, and 38,200 heart attacks annually
in the U.S …

31. REMEDIES
Alternative Energies:
• Adopting alternative energy sources can drastically
improve outdoor air quality.
• Replacing fossil fuel combustion with cleaner
technologies would decrease the production of carbon
dioxide.
• If people reduce the burning of sulphur-rich coal and
gas, they can lower the levels of sulfur dioxide and
nitrogen oxide.

32. Remedies
• Remove dust & dirt from every corner.
• Dispose of waste hygienically.
• Use biodegradable eco-friendly products instead of
plastics.
• Grow trees if you have a garden. Potted plants can be
put in small spaces. In over crowded areas air-purifiers
could be installed.
• Pure clean air is a need of the hour. Lets spread
awareness & ensure that the air around us is clean.

35. If we work together, we can achieve our goal of living in an
environment-friendly and green atmosphere.
Let’s join hands to have a clean and a green earth…!!
