The document discusses indoor air pollution, its causes such as fuel burning and lack of ventilation, and its significant negative health effects, including respiratory diseases and cancer. It highlights the severe impact of indoor pollution, particularly in developing countries, causing significant mortality rates each year. Control measures include improving ventilation and using specific indoor plants like aloe vera and spider plants that can filter harmful pollutants.

Control

2. Outdoor Pollution

3. But indoor
air can
be polluted
too . . .

4. 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

5. Causes
=
1 75-137
Amount of
Particulate mass
 One burning mosquito coil produces the same
amount of particulate mass (diameter up to 2.5 μm) as
75-137 burning cigarettes

6. Causes
=
1 51Emission of
Formaldehyde
 The emission of formaldehyde from one burning coil
can be as high as that released from 51 burning
cigarettes

7. 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

8. 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)

9. Control
 Proper ventilation should have to be
provided
 Then must have to be plant some indoor
plant …

10. Control
 It can filter benzene,
formaldehyde.
 Requires a lot of sunlight.
Aloe Vera

11. Control
 Best indoor plant to remove
formaldehyde from indoor
plant.
 It also battles benzene,
carbon monoxide.
Spider Plant

12. Control
 Have bright and colorful
flowers.
 Filter carbon monoxide
and benzene.
 Gives off oxygen at night.
It is ideal for bed room.
Gerbera

13. 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

14. 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

15. Control
 It can filter formaldehyde,
benzene and
trichloroethylene.
 Does not need too much
light to grow and thrives in
room temperature.
