1. Indoor Air
Pollution and
Control
Presented By – Partha Sarathi De

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.
