ABILA,IANA VEE P.

OBJECTIVES

• Be able to discuss what “air pollution” is all about.• Be able to determine the cause and

effect of polluted air.• Be able to understand the importance

of fresh air on species.

THE AIR

- is the ocean we breathe.- supplies us with oxygen which is essential for our

bodies to live.- is 99.9% nitrogen, oxygen, water vapor and inert

gases.

human activities can release into the air, some of which can cause problems for humans, plants, and animals.

The Top 10 Most Air Polluted Cities in the World

10. Kanpur, India Population: 3,221,435 major leather industry illegal glue factories levels of respiratory

diseases, asthma and eye irritation among the city’s population are increasing.

9. Yasuj, Iran Population: 96,786 manufacturing plants The city has plans to open a

refinery by 2014 that will produce gasoline, kerosene, gas oil, furnace oil, liquefied gas, asphalt and sulfur.

8. Gaborone, Botswana Population: 191,776 caused by landfills where

garbage is burned and by people who burn wood and even animal waste for cooking and heating.

worst in winter because of side effects of heating.

7. Peshawar, Pakistan Population: 3,625,000 vehicles have “catalytic

converters” suffers greatly from its

vehicle use. Burning of municipal solid

wastes.

6. Kermanshah, Iran Population: 822,921 dust problem The dust has caused a

number of people to be taken to hospitals for respiratory and heart problems.

5. Quetta, Pakistan Population: 896,090 construction activities and

smoke emission from motor vehicles and industrial units.

Iron mills, municipal wastes and the use of insecticides.

4. Ludhiana, India Population: 1, 740, 247 Is a highly industrial city

made Ludhiana one of the most polluted cities in the world.

200 premature deaths each year.

incidence of asthma is on the rise.

3. Sanandaj, Iran

Population: 311,446 crippling dust storms annual large particle

concentration is more than 12 times.

2. Ulaanbaatar, Mongolia Population: 2,754,685 visibly worse in the

wintertime. Emissions from motor

vehicles, industries, and power stations as well as road dust and household garbage burning are increasing.

1. Ahvaz, Iran Population: 1,338,126 Major industry,

transportation, and oil refineries bring this city to the number 1 spot on the list.

These particles can cause asthma, heart disease and lung cancer.

CAUSE &EFFECT OF

Prepared by: BAGAN,

MARVIN LAWRENCE

• One of the main cause of air pollution in the air is the burning of fossil fuels, especially coal.

• Power plant and vehicles consumes large amounts of fossil fuels releasing large amount of smokes and fumes into the atmosphere. Among this fumes is sulfur dioxide.

• When sulfur dioxide mixed with oxygen in the air and with water, it creates sulfur acid.

• When droplets of sulfuric acid gets heavy, they fall as acid rain which can kill fishes, crops and plants, destroy bodies of water such as rivers and lakes, and infrastructure.

The Acid Rain

• Aside from acid rain, exhaust fumes creates Smog (combination of smoke and fog). This is caused by trapped exhaust fumes in the upper layer in the atmosphere which prevents the normal circulation of air.

• Motor vehicles gives off carbon dioxide which helps turn the atmosphere into a kind of green house.

• Greenhouse effect happens when the carbon dioxide in the atmosphere traps heat. As carbon dioxide builds up, more heat is trapped, causing the atmosphere to warm up causing global warming.

• Global warming creates climate change, affects farming and may cause the ice in the polar region to melt and cause flood.

• CFCs or chlorofluorocarbons which contains chlorine, carbon, hydrogen, and fluorine creates holes in the ozone layer which are called “ozone holes”

• CFCs come from aerosol sprays, refrigerator, and from the manufacture of plastic foams.

• The major sources of air pollution vary from city to city. Automobiles produce nearly in Los Angeles. Furnaces in apartment and office building cause most of the contamination in New York city. Chicago’s air pollution comes equally from industry, motor vehicles and heating plants.

Reasons of Polluted Air

• Fuel combustion• Industrial processes • Burning of solid waste• Other sources

Actions Taken to Save the Earth

• Clean Air Act• Sin Tax Bill• Using Of Solar Panel Vehicle• Tree And Plant Planting• Using Biofuel• Using Of Mask, Handkerchief Etc.

IMPORTANCE OF FRESH AIR ON US

• Fresh air is good for digestion.--Fresh air helps you to digest food more effectively. That is why it’s great to take a small walk outside after you eat. From all the health benefits of fresh air, this one is really important if you are trying to lose weight.

• Improves your blood pressure and heart rate.--If you have a problem with blood pressure, you should avoid polluted environments and try to stay in surroundings that have a good supply of fresh air. Dirty environment forces the body to work harder, to get the amount of oxygen it needs.

• Fresh air makes you happier.--The amount of serotonin is affected by the amount of oxygen you inhale. Serotonin can significantly lighten your mood and promote a sense of happiness and well-being. Fresh air will leave you feeling more refreshed and relaxed.

• Strengthens your immune system.

--White blood cells kill and fight bacteria and germs. They need enough oxygen to work and function properly.

• Fresh air cleans your lungs.

--Fresh air helps the airways of your lungs to dilate more fully and improves the cleansing action of your lungs. When you exhale and breathe out through your lungs, you release airborne toxins from your body.

• You will have more energy and sharper mind.

--Fresh air helps you to think better and increases your energy level. Your brain needs twenty percent of your body’s oxygen. More oxygen brings greater clarity to the brain, improves your concentration, helps you to think more clearly and has a positive effect on your energy level.

RECOMMENDATION

• Join in any environmental groups (Clean & Green Project).

• Overall ban for illegal human activities.• Each of us should clearly understood the importance

of fresh air on us (human,animals,plants,trees,flowers etc.) and in order to save the earth.

• Reduced the use of things that might affect our environment.
