  • 1. AIR POLLUTION
  • 2. Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere.4
    Air pollution can be found both outdoors and indoors.  Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time.
    The sources of air pollution are both natural and human-based.  As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air.
  • 3. TYPES OF POLLUTION
    Types of Air Pollution
    Based on the possible reasons, air pollution could be classified into
    • Accidental air pollution
    • 4. Industrial air pollution
    • 5. Transport related air pollution
    • 6. Dwelling related air pollution
  • CAUSES
    Excessive burning of fossil fuels like coal, Kerosene, Petrol and Diesel.
    Smoke from factories and thermal power stations.
    Deforestation
    Use of certain substances like CFC (chlorofluorocarbons) in refrigerators and spray cans.
    Gases like Carbon monoxide , Carbon monoxide , Nitrogen dioxide ,etc. are released from vehicles, industries ,etc.
  • 7. EFFECTS
    Effects of Air Pollution are:
    It causes diseases like:
    1.Dizziness
    2.Headache
    3.Eye irritation
    4.Coughing
    5.Sore throat
    6.Chest pain
    7.Allergies
    8.Lung diseases
    2.Acid rain
    3.Greenhouse effect
  • 8. METHODS OF CHECKING
    AIR POLLUTION
    Vehicle Care: Timely servicing of the car helps to keep it in a good condition and also minimizes fuel exhaust and air pollution.
    Public Transport: Whenever possible, try to travel by public transports. This helps in two ways; prevents air pollution and increases public income. If you are going to a nearby place, go by walking or use bicycle, instead of using your vehicle
    Alternative Energy Source: Another effective way to prevent air pollution is to use alternative energy sources such as solar energy, hydroelectric energy and wind energy
    Saving Energy:Saving energy will, of course, help to prevent air pollution. Switch off the lights, fans, air conditioners, televisions, and other appliances, when not in use. You can also share a room with others when the air conditioner or fan is on, instead of switching them on in every room
    Minimize Air Pollutants: Always try to minimize smoke emission, as it can contribute to air pollution. One way is to compost dried leaves and kitchen waste, instead of burning them.
    Social awareness about air pollution is the most essential step to be taken for the prevention of air pollution. Awareness programs and/or advertisements should be encouraged, so that people understand the potential health hazards of air pollution.
