Outline  What is air pollution?  Air pollution problems  Health Effects  Reducing of air pollution  Conclusion

What is air pollution? Air supplies us with oxygen which is essential for our bodies to live. Air is 99.9% nitrogen, oxygen, water vapor and inert gases Air pollution is the release of particles into the air from burning fuel in automobiles, homes, and industries. It is also the release of gases. These can take part in some chemical reactions once they are in the atmosphere, forming smog and acid rain.

Formation of Air Pollutant

Indoor Air Pollution Sources of indoor air pollution  Tobacco smoke  Cooking and heating appliances  Vapors from building materials, paints, furnices, etc.

What can you do about Indoor Air Pollution? Use Products safely Use Products safely Restrict Smoking Restrict Smoking Use Appliances Property Use Appliances Property Select Building Material Carefully Practice Good Housekeeping Provide Adequate Ventilation

Outdoor Air Pollution Smog Smog Acid Rain Acid Rain

Smog  The result of chemical reactions between pollutants derived from different sources, automobile exhaust and industrial emissions and moisture in the air.  Cities are often centers of these types of activities, and many people suffer from the effects of smog, especially during the warm months of the year when the humidity is high.

Acid Rain When a pollutant, such as sulfuric acid combines with droplets of water in the air, the water (or snow) can become acidified. The effects of acid rain on the environment can be very serious. It damages plants by destroying their leaves; it poisons the soil, and it changes the chemistry of lakes and streams. Damage due to acid rain kills trees and harms animals, fish, and other wildlife. Damage due to acid rain kills trees and harms animals, fish, and other wildlife.

 This picture shows what a long term exposure to acid rain can do.The first picture is the original sculpture, the second one is how it looks right now.  How the trees have become leafless and dead because of their being exposed to acid rain. Acid Rain  The main pollutant that causes acid rain,comes from industries,which eject Sulphur Dioxide and Nitrogen Oxide into the atmosphere, that become part of the clouds and form acid rain

Health Effect Short term Short term Long term

Short-term effects Irritation to the eyes, nose and throat. Upper respiratory can be infected and cause such disease as bronchitis and pneumonia. Other symptoms can include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. In the great "Smog Disaster" in London in 1952, four thousand people died in a few days due to the high concentrations of pollution.

Long-term health effects Chronic respiratory disease such as lung cancer, heart disease Damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly. It is estimated that half a million people die prematurely every year in the United States as a result of smoking cigarettes.

Reducing air pollution ( By people) By driving a car that gets at least 35 miles a gallon, drive fewer miles, walk, bicycle or use mass transit when it is possible Replace luminous light bulbs with compact fluorescent bulbs Make your home energy efficient. Recycle newspaper, aluminum, and other materials Plant trees Avoid purchase products such as Styrofoam that contain CFCS

Reducing air pollution ( By Government) The government should make stricter clean air laws The government should make stricter clean air laws Enforcement and Development of International contracts to reduce ozone depletion and slow global warming.

The Earth is everybody’s home and nobody likes living in a dirty home. Together, we can make the Earth a cleaner, healthier and more pleasant place to live.
