  • Outdoor Pollution

  • But indoor

    air can

    be polluted

    too . . .

  • Causes

    Fuel burning (wood ,charcoal & animal dung)

    Absence of proper ventilation

    Smoking (Inhaling secondhand smoking still

    take over 4,000 chemicals)

    Asbestos, formaldehyde, varnish, paints

  • Causes

    =

    1 75-137Amount of

    Particulate mass

    One burning mosquito coil produces the same

    amount of particulate mass (diameter up to 2.5 m) as

    75-137 burning cigarettes

  • Causes

    =

    1 51Emission of

    Formaldehyde

    The emission of formaldehyde from one burning coil

    can be as high as that released from 51 burning

    cigarettes

  • Effects

    Short term effect Eye , throat irritation

    Long term effect Respiratory disease , cancer

    Expose to high level pollutant such as Carbon

    monoxide ,can even result in immediate death

  • Effects

    Outdoor-

    5,00,000 deaths/year

    Indoor-

    22,00,000 deaths/year

    (16,00,000 deaths/year Indoor fuel

    burning)

    Greater impact on developing

    countries(INDIA)

  • Control

    Proper ventilation should have to be

    provided

    Then must have to be plant some indoor

    plant

  • Control

    It can filter benzene,

    formaldehyde.

    Requires a lot of sunlight.

    Aloe Vera

  • Control

    Best indoor plant to remove

    formaldehyde from indoor

    plant.

    It also battles benzene,

    carbon monoxide.

    Spider Plant

  • Control

    Have bright and colorful

    flowers.

    Filter carbon monoxide

    and benzene.

    Gives off oxygen at night.

    It is ideal for bed room.

    Gerbera

  • Control

    Known as mother-in-law

    tongue.

    Can filter formaldehyde,

    nitrogen dioxide.

    At night takes CO2 and

    releases O2.

    Requires minimal sunlight

    & water.

    Snake Plant

  • Control

    It can filter formaldehyde.

    It grows in any type of light

    with an exception to sunlight

    (100% artificial lighting).

    Very easy to maintain.

    Golden pothos

  • Control

    It can filter formaldehyde,

    benzene and

    trichloroethylene.

    Does not need too much

    light to grow and thrives in

    room temperature.
