3. DEFINITION
• occurs when the air contains gases,
dust, fumes or odor in harmful
amounts.
• it is when concentrated gases
exceed safe limits.

4. TYPES OF AIR POLLUTION
• Outdoor Air Pollution
o Smog
o Particulates
o Acid Rain
o Greenhouse Gases
• Indoor Air Pollution

5. CAUSES
• Natural Sources
e.g. smoke that comes from
wildfires, volcanoes, methane, dust
• Human Sources
e.g. power plants and
automobiles, fumes, burning wood
stoves, fireplaces, and furnaces

6. Pollutants
• Carbon Dioxide
• Carbon Monoxide
• Sulfur Dioxide
• Nitrogen Dioxide

7. MECHANISM

8. Primary Mechanism
• Formation ofVOC
• Biological generation ofVOC
• Formation of liquid aerosol droplets
• Anthropomorphic generation of particulate
aerosol
• Biological formation of particulate aerosols
• Particulate aerosol formation

9. Secondary Mechanism
• Condensation
• Adsorption
• Nucleation

10. EFFECTS
• Human Effects
e.g. diseases
• Environmental Effects
• Acid rain
• Eutrophication
• Haze
• Wildlife
• Ozone Depletion
• Crop and forest damage
• Global Climate Change

11. IMPACTS
• Climate System
• Health
• Economy
• Environment
• Ecosystem

• Agriculture

13. CONCLUSION AND RECOMMENDATION
• Air pollution has long been a serious problem
in the world.
•Without air, Earth would be unable to sustain
life.
• Spread theWord.
