  • Outdoor Air Pollution: Each year, hundreds of millions of tons of gases and particulates pour into the atmosphere. Most of this pollution results from the burning of fuel to power motor vehicles and to heat buildings. Some air pollution also comes from business and industrial processes. Indoor air pollution occurs when buildings with poorly designed ventilation systems trap pollutants inside.

    2. 2. DEFINITION occurs when the air contains gases,dust, fumes or odor in harmfulamounts. it is when concentrated gasesexceed safe limits.
    3. 3. TYPES OF AIR POLLUTION• Outdoor Air Pollution o Smog o Particulates o Acid Rain o Greenhouse Gases• Indoor Air Pollution
    4. 4. 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
    5. 5. Pollutants• Carbon Dioxide• Carbon Monoxide• Sulfur Dioxide• Nitrogen Dioxide
    6. 6. MECHANISM
    7. 7. Primary Mechanism• Formation of VOC• Biological generation of VOC• Formation of liquid aerosol droplets• Anthropomorphic generation of particulate aerosol• Biological formation of particulate aerosols• Particulate aerosol formation
    8. 8. Secondary Mechanism• Condensation• Adsorption• Nucleation
    9. 9. EFFECTS• Human Effects e.g. diseases• Environmental Effects  Acid rain  Eutrophication  Haze  Wildlife  Ozone Depletion  Crop and forest damage  Global Climate Change
    10. 10. IMPACTS• Climate System• Health• Economy• Environment• Ecosystem• Forestry• Agriculture
    11. 11. MITIGATIONS Sustainable Development International Lower Conventions Emissions and Treaties Mitigation Lower of Air National and InternationalTransboundary Emissions Pollution funds, Eco- Conversion New Lower Technologies, Combustion Recycling
