Statistical analysis on
increase in air pollution and
its effectsBY,K.M.Bharthe
INTRODUCTION
Air pollution is the introduction of harmful substances like
chemicals,smoke etc into the atmosphere that causes damage
of the environment.
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
Sulphur oxides
Nitogen oxides
Carbon emmisions, especially CFCs
Particulates
Methane,Ammonia,Radioactive pollutants & Odors
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)
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.
its harmful effects are…
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
Steady Increase in emmision of greenhouse
gases since 1990
amount of release of cArbon in tonnes per person in various countries
Global warming is the rise in the average temperature of Earth's atmosphere
PH scale of Ozone
Cycle of Ozone
death rates due to air pollution
Some realistic facts and statistics about air pollution
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 …
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.
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.
So, Let’s aim towards “…Sustainable development…”
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…!!
